Resolving “Page errors on the GAM...” Error Message

The metadata structure of Microsoft SQL database is divided into numerous allocation units, such as, IAM (Index Allocation Map) pages, GAM (Global Allocation Map) pages, SGAM (Shared Global Allocation Map), or PFS (Page Free Space) pages. Corruption in any of the above pages primarily results into unmountability of database, further resulting into inaccessibility of database records. In addition, you receive an error message that states the exact cause of corruption. Few main reasons for metadata structure corruption could be unexpected system shutdown, SQL Server damage, virus hit, and human errors. To resolve all corruption scenarios and to access the database records, you will need to use restore the data from an updated backup. But there are millions of case studies proving that most of the database users forget to create a database backup. In such situations, these users need to use advanced SQL Recovery application.

As a practical case, you receive the underneath error message when you attempt to mount your MS Access database:

“Page errors on the GAM, SGAM, or PFS pages do not allow CHECKALLOC to verify database ID DB_ID pages from P_ID1 to P_ID2. See other errors for cause.”

The same error message appears repeatedly each time you attempt to mount your database. The above error message is a severity level 16 error message and can be caused either through logical or physical damage.

Cause:

The root cause for the occurrence of the above error message is corruption in GAM, SGAM, or PFS pages.

Resolution:

The error message can be resolved by using any of the below methods:
If caused due to physical damage, change the damaged system component with a brand new system component.
In case of logical damage, run DBCC CHECKDB command, with correct repair clause.
If both the above resolutions fail, restore the data from an updated backup.
However, if case of absence of a valid backup, repair the corrupt database using advanced SQL Database Repair utility. Such SQL Database Recovery utilities are competent enough to repair corrupt databases in all logical corruption scenarios. Database repair through these tools can even be performed by a non-technical user.

SQL Recovery is an efficient SQL Repair tool to surpass all SQL database corruption scenarios. The software incorporates advanced scanning methods to repair database created in SQL Server 2008, 2005, and 2000. It is designed for Windows 7, Vista, XP, 2003, 2000 and NT.

Table Corruption Post Meta data Structure Damage

Tables in MS SQL Server database act as a major storage component to save records with different data types. The data stored in the tables can be easily viewed by running a query. However, in some situations (when you receive an error message), the query may not display the desired records. One of the main reasons for the occurrence of the error message is corruption of table. The error message message halts the extraction of records, making them totally inaccessible. To access the records stored in the table, an easy way is to restore them from an updated backup. However, if the backup is not available, then you will need to repair the corrupt table. To do so, you will need to search for an advanced SQL Recovery application.

Picture a situation, where you receive the below error message when you attempt to access the records stored in a MS SQL Server database table:

“Table error: Object ID O_ID, index ID I_ID. Index node page P_ID1, slot S_ID1 refers to child page P_ID2 and previous child P_ID3, but they were not encountered.”

After the above error message appears, all the table records become inaccessible. Furthermore, the error message appears at every attempt of accessing the table records.

Cause:

The above error message pops up when the table gets corrupted due to metadata structure damage. The result of damage is that the index page in a B-tree can not see its child references, which are neighboring to its two lower pages.

Note: Database corruption can either be caused due to logical or physical factors.

Resolution:

For systematic resolution of the above error message and repair of corrupt table, you will need to follow underneath measures:
Physical damages can be surmounted only by changing the damaged system object with a new object.
Logical corruption can be surpassed by running DBCC CHECKDB command.
In case the problem persists even after running DBCC CHECKDB command, then you will need to repair your database table using an advanced SQL Database Repair software.

A SQL Database Recovery utility ensures comprehensive repair of corrupt database components by incorporating powerful scanning methods. In addition, these tools perform safe repair, without making any changes in original records saved in table.

How to Resolve “Database ID DB_ID, object 'OBJNAME' (ID O_ID)...”

The main purpose of DBCC CHECKDB command in MS SQL is to check the integrity (logical and physical) of all the specified database objects. The command performs three operations (DBCC CHECKALLOC, DBCC CHECKTABLE, and DBCC CHECKCATALOG) to comprehensively repair the corrupted database. While the repair command repairs your database in most situations, it might fail to repair in case of damage of critical system tables. In such circumstances, an easy way is to restore the data from an updated database backup. But in case of absence of an updated backup or the backup file itself getting corrupted, then you will need to search for advanced SQL Database Recovery application that can repair your database.

Consider a practical situation, where you receive the below error message when you attempt to mount your database:

“Database ID DB_ID, object 'OBJNAME' (ID O_ID). Loop in data chain detected at P_ID.”

After the above error message pops up, your database becomes unmountable. Furthermore, the data stored in your database becomes inaccessible.

Cause:

The root cause for the occurrence of the above error message is corruption in metadata structure of SQL database. Corruption can occur by both logical or physical reasons.

Resolution:

To resolve the above error message and to access the database records, follow the below three measures:

Swap the physically damaged system component with a new component.
Execute DBCC CHECKDB command (with appropriate repair clause.)
Restore the data from an updated database backup.

Out of the above three measures, the first measure provides complete resolution from the physical damage situations. The other two measures fail to perform in case the database is severely corrupted or there is no backup available. In such situations, the only alternative left is advanced SQL Repair software.

Such SQL Recovery tools ensure complete repair of most corrupted SQL databases. These applications come with interactive user documentation that makes the database user to easily understand the repair process. These repair tools are non destructive in nature.

Tips to resolve “Table error: Object O_ID... page P_ID was not encountered.” Error

The records in Microsoft SQL Server database can be placed and located in the form of a B-tree. These records are divided into various pages (child pages), each having a unique index page, which is one level up in hierarchy from the child page. Corruption in the hierarchical tree structure (metadata structure corruption) primarily results in loosing the reference of the child page from the Index page. In such situations, the data stored in the database becomes inaccessible. For accessing the data stored in the database, an ideal way is to restore it from an updated database backup. But if in case of absence of an valid database backup, you will need to use advanced MS SQL Database Recovery application to repair your database.

Consider a practical scenario, where you receive the below error message when you attempt to access the records stored in table:

“Table error: Object ID O_ID, index ID I_ID. Parent node for page P_ID was not encountered.”

The above error message makes the data stored in table inaccessible. Moreover, the error message repeatedly repeats every time you attempt to access the records stored in the table.

Cause:

The root cause for the occurrence of the above error message is SQL database corruption due to metadata structure damage.

Note: SQL database can be corrupted either due to logical or physical factors.

Resolution:

To resolve the above error message and to access the table records, you will need to follow the below measures:
To solve all the corruption issues caused due to physical damage, swap the corrupt system component with a new component.
To solve all the corruption issues caused due to logical damage, run DBCC CHECKDB command with correct repair clause.

The first measure is competent enough to resolve all the physical damage issues. The second measure, however, fails to resolve all logical corruption problems. For such situations, the database table can be repaired by using advanced MS SQL Recovery software. These SQL Repair utilities employ effective scanning methods to completely repair the corrupt table after all logical database corruption scenarios.

Resolving “Missing or invalid key in index...” Error Message

In SQL Server database, the data is primarily organized in two kinds of non-system pages – data pages (consist of data rows) and Index pages (consist of index rows). For every data row in a data page, there is always a pre-defined matching index row in Index page. However, if the index row is missing or corrupt, then you receive an error message that results into unmountability of your database. Records stored in an unmountable database are inaccessible. To access the records and continue with your work, you will need to use the data from an updated database backup. But if in case, the database backup has been corrupted or damaged, then you will need to use powerful third-party SQL Database Recovery application that can repair the database.

Consider a practical situation, where the below error message appears when you attempt to access the records stored in SQL database table:

“Table error: Table 'OBJNAME' (ID O_ID). Missing or invalid key in index 'INDEXNAME' (ID I_ID) for the row”

The above error message makes the records stored in your table inaccessible. Furthermore, the above error message pops up every time you attempt to access the table records.

Cause:

The fundamental cause for the occurrence of the above error message is missing of Index row.

Note: The above error message can be caused due to logical or physical corruption in SQL database table.

Resolution:

There are different ways to resolve corruption caused due to different reasons. These ways are discussed underneath:
Resolve the physical damage issues by swapping the damaged system component.
Resolve the logical damage problems by running DBCC CHECKDB command, with appropriate repair clause.

While the first resolution guarantees complete resolution from all physical damage scenarios, the second fails to repair database table in all logical corruption situations. For complete repair of tables after all logical corruption cases, you will need to opt for efficient SQL Recovery software. Such SQL Repair tools use powerful scanning methods to repair and restore the repaired table on default or user-specified location.

Resolving “Row error: Object ID....created NOT NULL, but is NULL in the row ”

SQL Server database corruption can have severe effects on the records stored in database components. One of the effect that most database users might encounter is wrong values being displayed under a particular column. Few major causes for database corruption can be improper system shutdown, SQL Server malfunction, virus infection, and more. An easy way to access data after corruption due to any of the above reasons is to restore the data from an updated backup. However, there might be circumstances where you have either not created any backup or backup itself is damaged corrupted. In such situations, you will need to search for advanced MS SQL Repair application that can systematically repair your corrupted database.

For example, the below error message pops up each time you attempt to mount your SQL Server database:

“Row error: Object ID O_ID, index ID I_ID, page ID P_ID, row ID S_ID. Column 'COLUMN' was created NOT NULL, but is NULL in the row.”

As the error message states, the columns which had NOT NULL values, now hold NULL values. The above error is 'severity level 16' message and can occur either due to software or hardware corruption issues.

Resolution:

The above error message can be resolved by following underneath error messages:

To isolate the problem caused due to physical damage of the system component, you will need to swap out the damaged system components with new components.
To completely resolve the issues created due to logical damage, you will need to execute DBCC CHECKDB command with appropriate repair clause.
Restore the database by using an updated database backup.

While the above resolutions are helpful in most of the issues, they fail in below situations:

DBCC fails to repair
Unavailability of database backup

To overcome both the above database corruption issues, you will need to use effective SQL Database Recovery software. Such SQL Repair tools thoroughly scan your database and allow you to restore the repaired database at user-specified location. These tools can be easily understood even by novice user.

Resolving “IAM page P_ID ... that should be in filegroupFG_ID2” Error Message

Mapping of MS SQL Server database is performed over a group of operating system files. The information related to data and logs is kept in different files, while single files are handled only by one database. The collections of all these files is known as filegroup. Two major functions that every filegroup performs are placement of data and administrative tasks. Corruption in any of the filegroups primarily results in unmountability of your database, which further results in inaccessibility of database records. To access your records after your SQL Server database becomes unmountable, a simple way is to restore the data from an updated database backup. But in weird situations where you have not created any backup or backup falls short to restore the records, you will need to start searching for an advanced third-party MS SQL Repair application.

Picture a scenario where you attempt to access the data saved in one of your SQL Server database, an you receive below error message:

“IAM page P_ID for object ID O_ID, index ID I_ID controls pages in filegroup FG_ID1, that should be in filegroupFG_ID2.”

Database records stored in your database do not appear because the above error message does not allow the database to mount. In addition, you repeatedly receive the above error message each time you attempt to access the database records.

Cause:

The root cause for occurrence of the above error message is damage of filegroup. Corruption can occur either due to logical or physical reasons.

Resolution:

Below are two measures that allow you to access database records:

Swap the physically damage component with a new component to overcome all physical damage issues.
Run DBCC CHECKDB command to surmount all logical issues.

Although the above resolutions prove successful in most cases, the possibility overcoming all logical corruption scenarios by using DBCC CHECKDB command is slightly less. In such situations, a powerful SQL Database Recovery application enables you to repair your corrupt database and access it records. Such SQL Repair tools use advance repairing procedures to thoroughly scan and repair the corrupt database.

Tips to Resolve “Database 'DBNAME' consistency errors...” Error Message

DBCC CHECKDB command is used to check the physical and logical integrity of MS SQL database objects. It is a three-stage process that performs DBCC CHECKALLOC, DBCC CHECKTABLE and DBCC CHECKCATALOG operations on the specified database. The command also validates the service broker data, contents of every indexed view, and link-level between file system directories and table metadata. While DBCC CHECKDB command repairs your SQL Server database in most situations, it might fail to perform under numerous circumstances. In such cases, an ideal way to is to restore the data from an updated database backup. But if in case, there is no database backup available or backup falls short to restore the lost data, then you will need to use advanced MS SQL Repair software.

As a practical scenario, you encounter the below error message while attempting to mount your Employee database:

“Database 'Employee' consistency errors in sysobjects, sysindexes, syscolumns, or systypes prevent further CHECKNAME processing.”

Above error message makes the data stored in the database inaccessible.

Grounds for the Error:

Corruption of Employee database either due logical or physical reasons.

Resolution:

To access the Employee database records and comprehensively resolve database corruption, you will need to follow the below measures:

To surmount damages caused due to physical damage of the system component, you will need to switch to a new system component. This can also include reinstalling the operating system.
To overcome the damages caused due to logical corruption, you will need to run DBCC CHECKDB command.

While DBCC CHECKDB command provides complete repair in most situations, it fails to perform when it finds error in Stage 2 (while running DBCC CHECKTABLE). This means that your system tables have been corrupted and DBCC CHECKDB can not repair your database. In such situations, the only way to repair your database is by using advanced SQL Database Recovery software.

Resolving “Text node referenced by more than one node” Error Message

Data, such as, tables, views, etc in SQL Server database is stored in blocks of 8Kb known as Pages. The two ways in which these Pages can be organized are clustered and non-clustered tables. While in clustered table the pages are linked in a doubly-linked list, the pages in non-clustered table may not be linked. Corruption in clustered table can damage the linking of the pages, further resulting in the unmountability of the SQL database. The records stored in the pages become inaccessible once the SQL Server becomes unmountable. For comprehensive accessing of all records in such situations, you will need to restore the data from an updated database backup. But if in case, the backup is corrupt, unavailable, or not even created, then you will need to use advanced third-party SQL Recovery application.

As a practical instance, you encounter the below error message while trying to access the records saved in a particular table:

“Text node referenced by more than one node. Object ID O_ID, text, ntext, or image node page P_ID1, slot S_ID1, text IdTEXT_ID is pointed to by page P_ID2, slot S_ID2 and by page P_ID3, slot P_ID3.”

Your database becomes unmountable after the above error message appears. Additionally, the error message pops up every time you attempt to access the table records.

Cause:

The reason responsible for the above error message is internal errors related to three pages involved in the above error message. These internal errors could be caused either due to physical or logical crash scenarios.

Resolution:

Below steps enable you to resolve the problem and access your database records:

Check for physical damage of the system component. If required, change the damaged system component
If the problem persists, run DBCC CHECKDB using appropriate repair clause to repair your database.
However, if the error message still appears and no backup is available, then you will need to use powerful SQL Database Repair tool. These MS SQL Repair applications use intensive scanning methods to and repair databases and recover all database components. Such tools are completely non-destructive in nature.

How to Resolve “CHECKTABLE processing of object ID...” Error Message

DBCC CHECKTABLE command in SQL Server database is used to check your database table for errors. The command creates a mini dump file in the SQL Server Log Directory whenever it detects that the table is corrupt or damaged. If you wish to access the records saved in the table in such scenarios, then you will need to restore the data from an updated backup. However, if in case the backup is not available or backup falls short to restore the table records, then you will need to search for advanced SQL Server Recovery application.

As a practical case, you view the below error message in mini dump file after you run DBCC CHECKTABLE command to check your table:

“CHECKTABLE processing of object ID O_ID, index ID I_ID encountered page P_ID, slot S_ID twice. Possible internal error or allocation fault.”

Your table records become inaccessible after the above error message appears.

Cause:

The root cause for the above error message is encountering of Page P_ID during the course of scanning.

Note: Table corruption can occur either due to logical or physical damage.

Resolution:

To resolve the above error message and to access table records, you will need to follow the below steps:

Restore the data from an complete backup.
In case of physical damage, change the damaged system component.
For logical corruption scenarios, run DBCC CHECKDB using appropriate repair clause.

Swapping the damaged system component provides complete resolution from all physical damage scenarios. The other two resolution fail to perform under tow scenarios:

The backup is unavailable.
Severe Corruption of the database.

To repair your corrupted database in the above scenarios, you will need to search for an efficient SQL Database Repair tool. These MS SQL Repair applications are developed by talented data recovery experts and repair databases after almost all logically corrupted SQL databases. These repair tools use high-end scanning methods to repair and restore the recovered database components on default or user-defined destination. These read only nature of these database repair applications ensure risk-free repair of database, leaving the original database file untouched and unmodified.

Resolving “Forward row mismatch” Error message

In SQL Server database, rows of a table are divided and stored into a series of partitions. These rows can either be saved in heap or B-tree structure. In heap tree structure, the table does not contain any Index and the forward row always points back to the forwarding row. However, in B-tree structure the rows are saved in accordance to the Index values. Corruption in metadata structure of your SQL database results in changing the values of these rows, thereby resulting in inaccessibility of all database records. An easy way to surpass such corruption scenarios is by using restoring the data from an updated backup. But, the possibility of backup being corrupted or damaged always exist. In such situations, an ideal way is to repair your database by using an effective SQL Server Recovery software.

Consider a scenario, where the underneath error message pops up every time you attempt to mount your database:

“Forwarded row mismatch: Object ID O_ID, page P_ID1, slot S_ID1 points to forwarded row page P_ID2, slot S_ID2; the forwarded row points back to page P_ID3, slot S_ID3.”

Your database records become inaccessible after the above error message appears.

Cause:

The main reason of the above error message is that the forwarded row (S_ID2 on page P_ID2) instead of pointing to forwarding row (S_ID1 on page P_ID1), is pointing to the wrong row.

Note: The above case can occur due to both logical and physical corruption scenarios.

Resolution:

The resolution for the above error message is mentioned below:

Swap the system component that is damaged with a new component.
Execute DBCC CHECKDB command.

While the former resolution to overcome hardware related issues is perfect, the later solution might fail to resolve logical corruption issues. For complete and systematic resolution in all logical corruption scenarios, you will need to opt for advanced SQL Database Repair tool. Such tools provide maximum MS SQL Repair by employing high end scanning and repairing algorithms. These tools are non-destructive and perform recovery without making any changes in the original database file.

Database Suspect due to Problems while Transaction Commit

A commit transaction in SQL Server is primarily used to make all the changes permanent which you performed since the start of transaction. Once you run the commit statement, all the resources held by the transaction are freed and the value for TRANCOUNT is set to “0”. Interruption while processing of commit transaction can result into making your database suspect. In such situations, your database becomes unmountable and the records stored in it become inaccessible. For complete access of database records after it has been corrupted, you will need to restore the data from an updated database backup. However, if the database backup is corrupted or unavailable, then you will need to use advanced third-party SQL Recovery application that can systematically repair your corrupted database.

A commit transaction can be halted due to below reasons:

A SQL Server CE application closes unexpectedly.
Windows CE device is reset.
SQL Server CE does not respond.

Your database is marked suspect after any of the above problem occurs. Furthermore, this leaves your database in an unrecoverable state. The above problems occur either due to power failure or an explicit reset during a transaction. Below are some prevention measures that enable you to minimize the effect of the problem:

Ensure that you have maintained a backup copy of your SQL Server CE database files.
To prevent database users from performing an explicit reset while a data manipulation process is in progress, add a progress bar in your application.
Always try to keep your transactions short.


Resolution:

To make your database records accessible, you will need to use Compact method. While the method repairs the database in many cases, chances of database corruption still exists. In such situations, the only way left to repair your database is by using advanced SQL Database Repair application.

These database repair utilities employ intensive scanning methods to repair your corrupted database and recover almost all database components. With highly-interactive user documentation, the MS SQL Repair software guides you through a complete repair process. The non-destructive software provides safe recovery of database components and provides an option to save them on default or new destination.

How to Resolve “Could not read and latch...” Error Message

Data storage space in SQL database is primarily divided into numerous pages. Each page contains a 96-byte header that contains information related to page number, page type, ID, and free space. Corruption in metadata structure primarily results in failing to read the data stored on the page. This further results in making the data stored in the database inaccessible. In such situations, the data stored in the database can be accessed by restoring it from an updated backup. However, there have been instances where the backup has not been created or the backup file is corrupted due to various logical and physical factors. For accessing your database records under such circumstances, you will need to search for an advanced third-party Recover SQL application.

Consider a practical scenario, where you encounter the below error message when you attempt to mount your SQL database:

“Could not read and latch page P_ID with latch type TYPE. OPERATION failed.”

The above error message appears each time you attempt to access the database records. Furthermore, the above error message makes the database records inaccessible.

Cause:

The root cause for the occurrence of the above error message is the failure of page read due to any of the below reasons:

The page is in repairing state.
An indeterminate function is being performed on the page.
The page might be read as a part of per checks of important system tables.

Note: The above scenarios can occur due to both logical and physical reasons.

Resolution:
To resolve the above error message and to execute your database records, you will need to
swap the damaged system component with a new one (for physical damages). For logical crash scenarios, you will need to run DBCC CHECKDB command (with correct repair clause).

Changing the damaged hardware component provides comprehensive solution to get rid of all hardware problems. But, in case of removing logical corruption scenarios, DBCC CHECKDB is not always a complete solution. For permanent resolution of all corruption scenarios, you will need to use a powerful SQL Database Repair application. Such MS SQL Repair software orderly perform database repair and recover all lost database components.

How to Resolve “Extent E_ID in database ID...” Error Message

The structure of an Index Allocation Map (IAM) page in MS SQL Server consists of one bit per dedicated extent for all the “Extents” in the file interval. The bit is allocated to the index of which the IAM page is a part. Corruption in the bit can result into inaccessibility of records stored in your database. Few major causes of corruption of the application damage, metadata structure corruption, malicious software like virus, and human errors. To access your data in such situations, restoration from an updated and valid database backup always helps. However, if the restoration could not be performed due to backup corruption, then the only way to access your data is by using advanced third-party SQL Server Recovery application.

Consider a practical scenario, where the underneath error message appears when you attempt to mount your SQL database:

“Extent E_ID in database ID DB_ID is allocated to more than one allocation object.”

The above error message halts the database mounting process making all the records saved in it inaccessible.

Cause:

The fundamental reason responsible for the occurrence of the above error message is bit corruption that results in the allocation of same extent to two different IAM pages.

Note: The above error message can also occur due to physical damage of your system's component.

Resolution:

To resolve the above error message and to access the database records, take the below measures:

In logical crash circumstances, run DBCC CHECKDB command (with appropriate repair clause).
The physical damages can only be resolved by making the swapping the damaged component with the new component.

While the above resolution for physical damage is always successful, the DBCC CHECKDB does not provides complete surety of repairing database after all logical crashes. To permanently resolve all logical corruption scenarios, you will need to use advanced SQL Repair tools. Such SQL Database Repair applications are built by highly talented database recovery experts and use high end repairing methods to repair your database. These tools come with interactive user documentation, that makes them easy to understand without any prior technical understanding.

How to Resolve “Table error: … out of range ...”

Nothing can be more frustrating than the inaccessibility of records stored in your database. There can be numerous reasons responsible for corruption, such as, metadata structure damage, MS SQL Server unexpected shutdown, virus attack, and more. A perfect resolution to get rid of all the corruption scenarios is by restoring the data from an updated database backup. But, there might be situations where you have either not created any backup or your backup has been damaged. These circumstances force you to use advance third party Recover SQL application that can easily repair your corrupted database.

As a practical scenario, you receive the underneath error message when you attempt to access the records stored in your SQL database:

“Table error: PAGETYPE page P_ID (object ID O_ID, index ID I_ID) is out of the range of this database.”

The above error message makes the database unmountable eventually resulting in the inaccessibility of records. Furthermore, the same error message pops up every time you attempt to access the database.

Cause:

The root cause for the occurrence of the above error message is that the IAM (Index Allocation Map) page is beyond the use of the file in which it is stored. This happens when the page maps an invalid interval or the first IAM page for an index is allocated as PageId_NULL.

Note: The above error message can occur due to both logical or physical damage.

Resolution:

Underneath are the resolutions that help you to resolve the error caused due to either logical or physical reasons:

Run DBCC CHECKDB command to in case of logical corruption.
Thoroughly examine the application the application and Microsoft Windows system logs to identify physical damage. In case, the logs specify the physical damage, then connect the hardware.

While the above resolutions prove successful in most situations, the possibilities of DBCC CHECKDB command falling short always exists. In such cases, you will need to opt for advanced SQL Repair software. Such SQL Database Repair are easy to understand by both technical and non-technical users as they are built with highly interactive user-interface.

Resolving “IAM page P_ID1 is pointed to by the previous pointer...” Error Message

An Index Allocation Map (IAM) page in MS SQL Server database act as a storage component to save information related to table extents and indexes. A single IAM page contains of two records – IAM page header and bitmap – and has the capacity to track 4GB of space to store. A linked list of all the IAM pages – IAM chain – tracks the space assigned to every single entity. Corruption in IAM chain primarily results in unmountability of SQL database. An unmountable database means inaccessibility of all the records. To access your records after IAM chain corruption, restore the data from an updated database backup. But, in absence of an updated backup or backup falling short to restore the required data, you will need to use advanced MS SQL Recovery application to repair your database.

Here is an instance to prove the above point. Consider a scenario, where you receive the below error message when you attempt to mount your database:

“IAM page P_ID1 is pointed to by the previous pointer of IAM page P_ID2 object ID O_ID index ID I_ID but was not detected in the scan.”

This error message stops the mounting process of your database resulting in making the records inaccessible.

Cause:

The above unmountable error message primarily occurs when the metadata entry in the IAM chain goes missing. This usually occurs due to metadata structure corruption.

Resolution:

The resolution for the above error message can be found out by following the below measures:


For logical corruption situations, you will need to run DBCC CHECKDB command (with repair clause) to repair your database.
For physical damage cases, you will need to examine the SQL Server and Microsoft Windows system logs. These logs help you to find the exact cause of damage. To permanently rectify the problem, change the damaged component with a new one.

While all the logical corruption scenarios can be solved using the above repair statement, there are still some possibilities of the database being not repaired. In such situations, if you want to repair your database, you will need to use a powerful third-party SQL Repair tool. Such SQL Database Repair applications are developed by highly qualified data recovery engineers and employ high end scanning methods to repair logically corrupted database.

Database Repair post “Table error: Page P_ID...” Error Message

Two main building blocks of every MS SQL database are pages and indexes. These pages store actual data and are always marked by a header that stores information such as, page number, page type, and free space. The page type in header section saves the data (Index, allocation map, etc.) that define the page. Corruption in the header might occur due to numerous factors, resulting into inaccessibility of records stored in the database. In most cases of SQL database corruption, you encounter an error message. To surmount the error message and access the SQL database records, you will need to restore the data from an updated backup. However, if the database backup file is corrupted, damaged, or inaccessible, then you will need to use advanced SQL Repair software.

Below is the error message that appears after the header gets corrupted or damaged:

“Table error: Page P_ID with object ID O_ID, index ID I_ID in its header is allocated by another object.”

The above error message appears every time you attempt to access the database records. In addition, the database records become inaccessible after the above error message appears.

Cause:

The above error message primarily occurs when a page contains a Index ID but is not allocated by any of the index's IAM pages. This happens in case of Index corruption, caused by either logical or physical crash.

Resolution:

Underneath are the resolutions for database repair caused due to logical or physical issues:

For logical crash circumstances, run DBCC CHECKDB command (with recommended repair clause) to repair your database.
For physical crash situations, examine the application and Microsoft Windows system logs. These logs enable you to determine the hardware responsible for damage. Swap the damaged hardware with a new one.

While physical damages can be convincingly solved by changing the hardware component, DBCC CHECKDB does not provide comprehensive repair in all cases.

Data Retrieval post Read/Write Error Message

Physical disk problems can be a result of various factors, such as, bad sectors on your hard drive, disk drive failure, or controller damage. A read/write error message pops up whenever your storage media gets physically damaged. This error message is primarily raised when you want to open a database file and MS SQL Server is unable to read the specified disk location. Furthermore, read/write error message disk problems leave your database in unmountable state making the records saved in it inaccessible. To overcome the hazards created by the error message, the best way is to restore the data from an updated backup. However, if the backup fails to restore the data due to its corruption or damage, then you will need to use advanced SQL Server Recovery services to recover your data.

As a practical instance, you experience the below read/write error message while attempting to access your database:

“%s: operating system error %d (%s) encountered”

Records stored in your database file become inaccessible after the above error message appears. Furthermore, the above error message repeatedly occurs each time you attempt to access the database records.

Cause:

The root cause for the occurrence of the above is the physical disk problem caused due to bad sectors, human errors, hard disk controller damage, and many more similar reasons.

Resolution:

To comprehensively troubleshoot the above error message and access the database file, you will need to identify the damaged device by selecting the row from “sysaltfiles”, which contains same disk name mentioned in the error message:

USE master
GO
SELECT name, filename
FROM master..sysaltfiles
GO
The output of the above query displays the name of physical name of your hard disk.

Self-examine your hard disk and correct the problems. While the problem may solve at your end, the probability of database getting further corrupted always high. To ensure any further damage, it is advisable to opt for advanced SQL Repair services. These SQL Recovery services are provided by data recovery organizations and are performed by highly talented data recovery experts.

Applying CHECKDB On Tempdb Cause Data Loss

The tempdb database is a global resource of MS SQL Server, which is available for all users that are connected to instance of Microsoft SQL Server. This database stores temporary user objects, internal objects that are designed by SQL Server Database Engine, row versions that are resulted by data alteration transactions and row version that are resulted by data alteration transactions for features. In some cases, when you try to repair a damaged tempdb database using CHECKDB command, SQL Server database corruption may occur. This behavior renders all of your mission-critical data inaccessible and thus you need to opt for SQL Recovery solutions to retrieve data.

In a practical scenario, when any of the database user raise attentions during process of SQL Server, you might come across any of the below error message:

Server: Msg 8946, Level 16, State 1, Line 1
Table Corrupt: Allocation page (1:253) has invalid IAM_PAGE page header values. Type is 1. Check type, object ID and page ID on the page.

Or

Server: Msg 8906, Level 16, State 1, Line 1
Page (1:253) in database ID 2 is allocated in the SGAM (1:3) and PFS (1:1), but was not allocated in any IAM. PFS flags 'IAM_PG MIXED_EXT ALLOCATED 0_PCT_FULL'.

Attains are raised by SQL Server clients while server is executing or performing commands, necessitating non-logged allocations in tempdb file like worktables for the cursors.

Cause

As stated in above error, this issue is caused by corruption to the SQL Server database table. When the database table gets damaged, an invalid value is written in header of IAM_PAGE page of table and the operating system could not identify table and gives you error messages.

Corruption to the SQL Server database table might occur due a number of reasons ranging from improper system shutdown to virus infection. When database corruption occurs, it neither accessed nor repaired through CHECKDB utility.

In such situations, you need to repair and restore the database using third-party SQL Repair applications to retrieve inaccessible or damaged data. The SQL Recovery tool perform systematic scan of affected database to ensure absolute recovery.

The software are quite easy to use as they have self-descriptive and interactive graphical user interface. SQL Repair is completely safe with these programs as they have read-only and non-destructive conduct.

SQL Server Metadata Corruption After Importing Data From Excel File

In Microsoft SQL Server, you can import or export data through Import/Export Wizard. This wizard offers simplest way to create an Integration Services package, which copies data from a source to destination. The MS SQL Server Import/Export Wizard could copy data from and to a data source for which a native OLE DB provider or a managed .NET Framework data provider is available. Microsoft Excel is one such application. But sometimes, after importing data from Excel spreadsheet, the database may not be accessed. This behavior can occur due to corruption and lead to critical data loss situations. At this point, you need to opt for SQL Recovery solutions to retrieve business-critical data from damaged database.

In a practical scenario, when you try to open a SQL Server database after importing data from an Excel spreadsheet that was originally created using data from SQL resultset, following errors may occur and prevent you to access the database:

“The component has detected potential metadata corruption during validation.
Error at Update Counterparty Table with new counterparties [DTS.Pipeline]:
The package contains two objects with the duplicate name of 'output column'”

And

“It may not be possible to recover to a valid state using a component-specific editor. Do you want to use the Advanced Editor dialog box for editing this component?”

When this issue occurs, MS SQL Server database become inaccessible. In order to sort out this problem, you need to find out the cause of this issue and go for SQL Repair by resolving it.

Root of the issue

As stated in above error message, this problem occurs due to metadata corruption in SQL Server database. SQL Server use a number of metadata for effective management of database. The metadata are used for easily accessing data from database. When they gets damaged, SQL Server can not find the required data and thus you come across data loss situations.

To retrieve data in such scenario, repair and restore damaged database through third party SQL Recovery applications. These software are particularly designed to thoroughly scan the affected database and retrieve all of its damaged and inaccessible objects such as stored procedures, triggers, tables, reports and forms. These tools are completely safe and easy to perform SQL Repair in all database corruption circumstances.

SQL Recovery is the best ever made and the most advanced application that repairs and restores all of the SQL Server database objects. It supports recovery from Microsoft SQL Server 2008, 2005 and 2000. This software is compatible with Microsoft Windows Vista, 2003, XP, 2000 and NT.

Damaged SQLServerAgent Service Might Cause MDF Corruption

Microsoft SQL Server is an advanced RDBMS (Relational Database Management System), which include a service called SQLServerAgent for managerial operations of MS SQL Server, known as Jobs. This service executes the jobs and monitor the tasks for SQL Server. It is also able to process the SQL Server alerts. But in some situations, where the SQLServerAgent gets damaged, database might get damaged and become inaccessible. In these situations, you can not access your mission critical data from the damaged database and need to opt for SQL Recovery to get your data back.

In MS SQL Server, a job is usually a collection of steps that are particularly designed for the simplification of tasks of users. There are several functions that could be carried out through the jobs and information of these jobs is stored in SQLServerAgent. The critical functions include backing up the database that could be generated on regular intervals, specified as per users' choice. But if the functioning of this utility is aborted, then backup process might get terminated and some other database operations may also get terminated.

This utility tells you about the errors in the database, which occurs while executing the database jobs. But in case if the error numbers raise, which have six or more digits then heap corruption might take place in SQLServerAgent service. At this point, you might come across below error message in the sqlagent.log file:

“The ExecReAlloc memory operation failed (request [for 1508 bytes] occurred at line 2409 of function ODBCErrorHandler)”

In such circumstances, you would not be able to access the service and thus no database job will run. This behavior of SQL Server renders entire database inaccessible and cause MDF corruption. To gain access of your mission critical data in these cases, SQL Repair is required.

Cause

The major reason behind this problem is the routine for procession the errors in SQLServerAgent doesn't allocate disk space that is sufficient for storing errors numbers that is greater than 5 digits. To prevent this issue, Microsoft recommends you to use error numbers that are 5 digits long.

In case of corruption, you are required to repair and restore damaged database through SQL Recovery solutions. Recovery is best possible using third party applications. These tools are quite effective in most of the database corruption situations. SQL Repair using these applications is completely safe and easy.

If you work on Microsoft SQL Server, you must know the actual value of T-SQL (Transactional Structured Query Language) commands. These commands help you to access and alter the Master Database File (MDF) in an easy and effective fashion. Other useful features of such commands include absolute control on transactions, error handling and row processing. This is recommended not to use such commands concurrently on same SQL Server database component, because it might cause serious corruption to database or its components. In such situations, the database become inaccessible and you come across critical data loss situations. At this point, to retrieve your valuable data from the database, you are required to carry out SQL Recovery using appropriate tools.

Outcomes of executing two T-SQL command concurrently

When you run two T-SQL commands at the same time on same database, database inconsistencies might occur and you come across some error messages. Take an instance of two T-SQL commands DBCC SHRINKDATABASE and DBCC DBREINDEX, which you run concurrently on any particular database table (Employee) of an SQL Server database. The DBCC SHRINKDATABASE command is used to shrink the database size, whereas DBCC DBREINDEX command is helpful in rebuilding the indexes in database table. In this scenario, you might encounter below error message:

“Error: 8909
Table Corrupt: Object ID 0, index ID 0, page ID (1:623). PageId in the page header = (0:0).”

The moment you encounter above error message, shrink operation on database table gets terminated. Furthermore, the Employee table becomes damaged and inaccessible. It generally occurs due to simultaneous execution of more than one T-SQL commands simultaneously.

In such critical situations, you need to find out the solution, which could perform effective SQL Repair on database and all of its objects. To handle minor consequences in the database table or the database, you can use DBCC CHECKDB command. This is an inbuilt command line utility of MS SQL Server.

However, when the DBCC CHECKDB command can not resolve database corruption problem, you need to go for SQL Recovery using third party tools. These applications are capable of handling most of the MDF file corruption situations.

They use high-end scanning algorithms to throughly scan damaged database and ensure absolute and easy recovery of all the database objects. This SQL Repair software is quite easy to use and thus do not demand sound and prior technical skills.

SQL Recovery is the most advanced and powerful software to successfully recover damaged SQL Server database. It works well with Microsoft SQL Server 2008, 2005 and 2000. This software is compatible with Microsoft Windows Vista, 2003, XP, 2000 and NT.

MDF Corruption After Transferring Data to sql_variant Column in SQL Server

When you use DBCC CHECKDB command on SQL Server database (MDF) file, you may face database inconsistency problems that could cause issues like database corruption. In case of corruption, SQL Server can not recognize the MDF file and thus data stored in it becomes inaccessible. To resolve MDF corruption issues, you need to repair and restore the MDF file using SQL recovery software.

The DBCC CHECKDB command might display error messages due to database inconsistency in your SQL Server database. It takes place when the underwritten conditions are true:

MS SQL Server loads data to the column which has a sql_variant data type.
The data gets created in another column which has a sql_variant data type and the data is sent on-the-wire by the SQL Server.
Data is sent either to an intermediate file or directly to another database server based on Microsoft SQL Server.
sql_variant column holds character values.

In case of database inconsistency, SQL Server may not work properly and data stored in the MDF file can not be accessed. Here are some examples of the SQL statements which could result into such behavior:

A BULK INSERT or BCP statement from the file which was originally created using SELECT statement or BCP IN command from the SQL Server.
Data load which is using the Data Transforming Services.
Data load which is using the SQL Server DMO Transfer Object.

In case of MDF file corruption, you may encounter the below given error message:

"Msg 2537, Level 16, State 43, Server MYSERVER, Line 1
Table error: Object ID 1977058079, index ID 0, page (1:75), row 0. Record
check (Valid SqlVariant) failed. Values are 4 and 0.
DBCC results for 'MyTable'.
There are 0 rows in 1 pages for object 'MyTable'.
CHECKDB found 0 allocation errors and 1 consistency errors in table.”

In case of corruption, MDF file repair is required to access data from the database. It is best possible using third party SQL Repair software. These software incorporate efficient scanning mechanisms to scan the damaged MDF file and extract all the data from it.

SQL Recovery software are result-oriented and easy-to-use tools that do not require sound or prior technical skills to achieve recovery of your precious data.

SQL Recovery is the most advanced and powerful SQL Repair application that ensures complete repair of your corrupt database (MDF) file. It supports Microsoft SQL Server 2005 and 2000. The software is compatible with Microsoft Windows Vista, XP, 2003, 2000 and NT.

Sysindexes.statblob Column Corruption after Running DBCC DBREINDEX Statement

After you apply the DBCC DBREINDEX T-SQL statement to rebuild one or more of the indexes for a database table in a particular SQL Server 2000 database, the indexes and statistics of the database may get damaged. This behavior results as data inaccessibility and database corruption which causes data loss. In order to resolve such behavior of Microsoft SQL Server 2000, you should opt for SQL Recovery solutions.

After running DBCC DBREINDEX statement on SQL Server database, the sysindexes.statblob column might get corrupted if the following conditions are true:

The table has a computed column.
Some columns in the table are referenced by more than one indexes or statistics.
The table is referenced by an indexed view.
You have re-indexed the table using DBCC DBREINDEX command.

Auto create statistics option is enabled for database.

When you run the DBCC CHECKDB command on the database, you come across the following corruption error messages on sysindexes.statblob column:

Server: Msg 8964, Level 16, State 1, Line 2 Table error: Object ID 2. The text, ntext, or image node at page (1:64), slot 29, text ID 6815744 is not referenced.
Server: Msg 2576, Level 16, State 1, Line 2 IAM page (0:0) is pointed to by the previous pointer of IAM page (1:88) object ID 1977058079 index ID 2 but was not detected in the scan.

Corruption to the sysindexes.statblob column might also damage the whole MDF file.

Sysindexes.statblob is a column of sysindexes table which is used by SQL Server to store statistics of a column or an index key. It is an image data type which stores a histogram with a sampling of values in column or index key.

The ultimate result would be the inaccessibility and loss of your mission critical data. Thus, you need to perform SQL Repair to resolve this problem and to get your data back.

This is best possible with the help of powerful third-party SQL recovery applications. These software use effective scanning mechanisms to thoroughly scan entire MDF file and extract all data from it. The software come with interactive interface and to-the-point documentation that enables you to perform SQL Repair on your own.

SQL Recovery is the most comprehensive SQL Repair software that can repair and restore damaged MDF files in most of the data loss situations. It can repair and restore MDF files of SQL Server 2005 and 2000. The software is compatible with Windows Vista, XP, 2003, 2000 and NT.

CHECKDB Fails to Fix Error 8909 and 8905

DBCC CHECKDB commands allow checking logical and physical SQL Server database integrity. When used with REPAIR_ALLOW_DATA_LOSS argument, it repairs all reported errors, but with the possibility of data loss. The corrupted data gets deleted in the process. But at times, when you run DBCC CHECKDB command with REPAIR_ALLOW_DATA_LOSS argument, database corruption is reported as fixed though is not corrected. In such situations, you can use your recent data backup to restore the database. But if the backup fails to restore or is not present, you need to scan your damaged database with powerful SQL recovery applications.

Consider a practical instance, you scan your SQL Server 2000 database and get 8909 error, followed by a group of eight or more 8909 error messages:

Server: Msg 8905, Level 16, State 1, Line 1
Extent (1:192) in database ID 10 is marked allocated in the GAM, but no SGAM or IAM has allocated it.

Or

Server: Msg 8909, Level 16, State 1, Line 1
Table error: Object ID 0, index ID 0, page ID (1:192). The PageId in the page header = (0:0).

Further, you use DBCC CHECKDB with REPAIR_ALLOW_DATA_LOSS option and it reports it as fixed. But again, when you run DBCC CHECKDB command to check database integrity, it reports the same error messages.

Cause

You encounter this issue when the following conditions are true:

You run DBCC CHECKDB on pages and extents that are allocated for sorting
Pages have field values such as Page type is set to SORT_PAGE (7), Index ID is 0 and Object ID is 0
You haven’t installed SQL Server 2000 Service Pack 2 or later.

Solution

To resolve the issue, you can follow any of these methods:

Install SQL Server 2000 Service Pack 2 and run DBCC CHECKDB command with repair_allow_data_loss option
Use DTS (Data Transformation Services) and transfer the database out.

If the above measures don’t help or the database still appears to be corrupt, you need to use efficient third-party SQL repair applications. These are the commercial tools provided to scan and repair damaged SQL Server databases. You can use these SQL Recovery products in any case of SQL database corruption.

SQL Recovery is the finest SQL Repair tool to scan and repair damaged or corrupt SQL Server databases. The software performs safe repair operations and restores all database components. It is compatible with SQL Server 2005 and 2000. The software supports Windows Vista, XP, 2003, 2000 and NT.

Assertion or MDF Corruption When You Import Data in SQL Server 2000

You may face database corruption or receive an assertion in SQL Server 2000 when you use the “Bulk Insert” T-SQL (Transaction Structured Query Language) command or BCP (Bulk Copy Program) utility to import data. In such situations, data from SQL Server MDF files can become inaccessible. SQL Database Recovery is required to overcome such issues.

BCP is a command line utility in SQL Server that is used in a script or batch file to automate the import and export processes through text files. To import data in a table, you must either understand the structure of table and types of data or use a format file designed for that table.

When you use BCP command line utility or Bulk Insert T-SQL command for importing data, MDF corruption may occur and you may get the following error message:

“Server: Msg 823, Level 24, State 2, Procedure gfspTMAppendText, Line 20 I/O error (bad page ID) detected during read at offset 0x0000000024e000 in file 'C:\Program Files (x86)\Microsoft SQL Server\MSSQL\data\'.”

You receive following information in error log of SQL Server 2000:

1.“DateTime spid53 SQL Server Assertion: File: , line=466 Failed Assertion = '0'.”
2.“DateTime spid53 Error: 3624, Severity: 20, State: 1.”

If you run DBCC (Database Consistency Checker) command like DBCC CHECKDB command to find and repair corruption in the database, you receive further error messages stating:

1.“Server: Msg 8909, Level 16, State 1, Line 1 Table error: Object ID 0, index ID 0, page ID (1:105). The PageId in the page header = (0:0).”
2.“Server: Msg 8928, Level 16, State 1, Line 1 Object ID 2009058193, index ID 255: Page (1:105) could not be processed. See other errors for details.”

Such SQL Server behavior causes critical data loss. You should figure out the cause to Repair SQL database and gain access of your lost data.

Root of this issue

You may experience assertion and MDF corruption problems, if following conditions are true:

You use Bulk Insert or BCP utility together with the FIRE_TRIGGERS option.
You import a database table which has an after trigger that updates the text column of another database table.

Resolution

You can fix database corruption with the help of SQL Database Recovery software. These are highly automated tools that completely scan the corrupted MDF file and extract all of its objects as tables, stored procedures, indexes, views, triggers, constraints etc.

SQL Recovery is the most advanced SQL Database Recovery tool. It can Repair SQL database components like tables, views, rules, stored procedures, defaults, user defined functions and data types along with triggers. It is compatible with Microsoft SQL Server 2005 and 2000. It supports Microsoft Windows Vista, XP, 2003 and 2000.

Index Corruption in SQL Server Might Damage MDF File

In Microsoft SQL Server, a database index is the data structure, which enhance speed of operations on database table. You can create database indexes using single or multiple columns of table, providing efficient access and random lookups of ordered records. The offer better management of data in SQL Server database and enhance improve performance. But in case if the database index gets damaged, you might come across serious problems. Index corruption might make your database inaccessible and cause data loss. At this point, you need to repair and restore the database using SQL Recovery solutions to gain access of your mission critical data.

In a practical scenario, when you attempt to access MDF (Master Database File) of MS SQL Server, you might come across below error message:

"Possible index corruption detected. Run DBCC CHECKDB."

After above error message, you can not perform any operation on the database and can not access data from it. In order to gain access of your valuable data, you are required to find out the cause of this problem and go for SQL Repair by sorting it out.

Root of the issue

This is an event log error message, which occurs when MDF file or its components gets damaged. The SQL Server database might get corrupted or damaged due to a number of reasons such as virus infection, software malfunction, improper system shutdown, registry errors and so forth. When any of the above situations occur, it might directly affect your business in terms of finance and decreased market revenue.

Solution

As recommended in above error, you could resolve this issue by using “DBCC CHECKDB” command on affected database. It is an in-built MS SQL Server command like tool, which checks the integrity of database, find errors and try to fix them.

But in case if this utility can not help you to resolve the issue, go for SQL Recovery software. These are advanced third party applications, which carry out efficient scan of damaged database to retrieve all of its objects including tables, reports, forms, triggers and stored procedures.

With interactive and simple graphical user interface, these SQL Repair software are completely easy to use and thus do not demand sound technical skills. They do not alter contents of the database as they have read-only approach.

SQL Recovery is the most excellent solution for all MDF corruption situations. It works well with Microsoft SQL Server 2008, 2005 and 2000. This softwre is compatible with Microsoft Windows Vista, 2003, XP, 2000 and NT.

Incorrect Configuration of SQL Server 2005 May Lead to Database Corruption

Microsoft SQL Server is the most advanced and widely used RDBMS (Relations Database Management System). It stores all of your critical data in MDF (Master Database File), in the form of tables. But in case if the SQL Server gets damaged, it does not allow you to properly mount the database and access data from it. There are several possible scenarios of SQL Server corruption, which include virus infection, application crash, improper system shutdown, file system corruption and operating system failure. All these situations cause critical data loss and require SQL Recovery to be sorted out. You should always opt for reliable and effective solutions for absolute recovery.

As as example of SQL Server corruption, when you try to start Microsoft SQL Server 2005, you might encounter below given error message:

"Could not start the SQL Server (SQL2005) service on Local Computer

Error 14001: This application has failed to start because the application configuration is incorrect.
Reinstalling the application may fix this problem."

Subsequent to above error message, MS SQL Server database become unmountable and inaccessible. The major reason behind occurrence of above error message is damaged or incorrect SQL Server configuration settings. In order to access database in these cases, you need to reinstall SQL Server 2005.

Although, reinstalling SQL Server might help you to carry out SQL Repair, but it is not safe at all. When you reinstall the application, data loss might take place. After you reinstall the SQL Server, the database might get damaged and it can not be reattached with the server.

The problems might occur due to SQL Server edition mismatch. MS SQL Server is available in 64-bit and 32-bit editions. The 64-bit edition uses Windows Installer to perfectly integrate installation of SQL Server characteristics in single feature tree. But if the hardware is not compatible with particular edition, the installation might fail.

No matter what the cause is, database corruption can not be accepted at any cost and it cause serious data loss issues. In these cases, you need to repair and restore the damaged database and retrieve all of its objects using third party SQL Recovery software.

These applications are particularly designed to perform in-depth scan of affected database and successfully restore it. The SQL Repair tools have interactive and simple graphical user interface to enable Do It Yourself recovery. With read-only and non-destructive conduct, they are completely safe to use.

Damage Registry of SQL Server Agent Cause Database Corruption in SQL Server 2008

Registry is the most important component of Microsoft Windows operating system. Whenever you install a software (such as Microsoft SQL Server 2008) or hardware on your computer, a new registry hive is created. But in case if the registry entries of Microsoft SQL Server gets damaged, the database corruption might occur and it may become inaccessible. In such situations, you encounter data loss circumstances and need to go for SQL Recovery solutions to get your valuable data back.

For example, consider the below scenario:

In the clustered instance of MS SQL Server 2008, SQL Server Agent registry checkpoint is missing due to some unexpected corruption problems or deletion problems.
You repair clustered instance of MS SQL Server.

In above scenario, the Windows registry subkey, which is associated with MS SQL Server Agent isn't found in list of checkpoints of SQL Server Network Name resource. The resource is associated with clustered instance. Furthermore, updates for SQL Server Agent application configuration aren't propagated to other nodes of cluster when SQL Server group of resources move to those nodes.

Below is the registry subkey, which applies to the SQL Server Agent:

HKEY_LOCAL_MACHINE\Software\Microsoft\Microsoft\SQL Server\\SQLServerAgent

Resolution

In order to sort out this problem, go through underwritten steps:

Point to Start-> Run and type cmd and click OK button.
Type cluster . resource /checkpoints on command prompt and press Enter key.
Check whether the below registry key appears in the result of above command:
HKEY_LOCAL_MACHINE\Software\Microsoft\Microsoft SQL Server\\SQLServerAgent
If the registry does not appear, then type below command and press Enter key:
cluster . resource /addcheckpoints:"HKEY_LOCAL_MACHINE\Software\Microsoft\Microsoft SQL Server\\SQLServerAgent"

If this method can not help you to sort out the issue, then you are required to repair and restore the database to carry out SQL Repair. This is possible with the help of powerful third party applications, known as SQL Recovery software.

These tools use advanced and efficient scanning mechanisms to carry out in-depth scan of affected SQL Server database and retrieve all of the corrupt or inaccessible objects. The SQL Recovery softwre are generally easy and safe to use. They do not demand high technical skills.
