SQL Server Database marked Suspect error

Article by Mahi Sony

To successfully configure, manage, develop and access all the SQL server components, an integrated environment named SQL Server Management Studio (SSMS) is provided to the database users. Corruption in SSMS results in inaccessibility of SQL database components and various error messages. In such circumstances, the user needs to use effective SQL Recovery software.

For example, when a user attempts to connect to the SQL database and opens SSMS, he encounters this below error message:

“Database ‘msdb’ cannot be opened. It has been marked suspect”

The main cause of the above error message is that the SQL database has been suspected. This situation occurs under following conditions:* When the error log file does not match with the database file* SQL database corruption

When the user views the SQL Server application event log, he finds the following entry:

“The log scan number (152:284:1) passed to log scan in database ‘msdb’ is not valid. This error may indicate data corruption or that the log file (.ldf) does not match the data file (.mdf). If this error occurred during replication, re-create the publication. Otherwise, restore from backup if the problem results in a failure during startup.”

Once the above error message appears on the screen, SQL database becomes inaccessible. To resolve the above problem, the user can use an inbuilt tool named sp_resetstatus. This tool enables the user to change the SQL database status and access the SQL database again. But in this case, this inbuilt tool will not be able to resolve the issue. This tool will only allow the user to connect to the SQL Server instances and will let you access other databases. To resolve the above error message and perform complete sql database recovery, the user needs to use a third party application known as SQL Recovery software.

Error Messages while restoring the MS SQL Server database

Article by Naveen Kadian

Restoration of data from an updated database backup allows you to overcome almost all SQL Server database corruption scenarios. It is therefore, always recommended to maintain a systematic database backup on some other storage media as well. While restoration of data is an easy process, it might result into an error message, which prevents you from restoration of the database. In such situations, an easy way is to restore the data from any other updated database backup. However if in case, no other backup is available or backup falls short to restore the data, then you will need to opt for advanced third-party SQL Database Recovery application.

Consider a practical scenario, where you encounter the underneath error message while restoration of data:

“Msg 8967, Level 16, State 216, Server <server name>, Line 2 An internal error occurred in DBCC which prevented further processing. Please contact Customer Support.DBCC results for ‘<database name>’.Msg 8921, Level 16, State 1, Server <server name>, Line 1Check terminated. A failure was detected while collecting facts. Possibly tempdb out of space or a system table is inconsistent. Check previous errors.”

On viewing the your SQL Server log, you view another error message:

“2007-05-26 07:13:49.21 spid58 DBCC encountered a page with a LSN greater than the current end of log LSN (<LSN>) for its internal database snapshot. Could not read page (file id:page id), database ‘<database name’ (database ID database id>), LSN = (<LSN>), type = 32, isInSparseFile = 1. Please re-jog this DBCC command.”

While the restoration process halts, the data stored in the database becomes unaccessible.

Cause:

The above error message principally occurs when the DBCC CHECKDB command is ineffectual to function the asked checks that sustain the consistency of your database. These checks could not be done owed to numerous reasons, such as SQL Server database corruption, metadata structure damage, and more.

Resolution:

To adjudicate the above error message and to access the database records, you will take to use advanced SQL Repair tool that provides comprehensive repair of crooked database. Such SQL Repair tools are non-destructive in nature as they do overwrite or optimize the original records of the database.

Error 3403 in SQL Server

A SQL Server database is comprised of two basic components, viz. data files and transaction logs. A transaction log file is the one which records uncommitted transactions of database. If due to any reason, SQL service shuts down unexpectedly, the next time when you restart the server, it analyzes all the transaction log files and if not committed, it rolls back all the changes that have been performed as the part of such transactions. But sometimes, this recovery procedure fails to end successfully and database remains in corrupted state. Such situations require you to restore from the last good backup. However, if no backup is available or is damaged, you should use SQL applications.

You might encounter the below error message with your SQL Server database:

Error 3403, Severity 22
During recovery initialization, page %ld was encountered.

This page belongs to object %ld, not the log

Cause

After the SQL crash, SQL Server automatically tries to recover. While it occurs, it scans the complete transaction log till the last page. If it finds a page, which is allocated to syslogs but the object ID on the page header doesn’t match with that of syslogs, it displays error 3403 and recovery fails. It occurs because of following possible reasons:

• A SQL Server problem resulted in a bad write or page allocation
• Allocation page was updated and SQL Server went down before the transaction log page could be written. So, when later SQL database rebuilt itself, it did it without transaction log pages being cleared, while the old log entries still exist.

Solution

To solve such issues, you should apply these methods:

• Check your backup status.

If a clean backup exists, drop the damaged database and load it from the backup
• If no valid backup exists, use commercial SQL recovery applications to repair and restore the database

SQL Repair software are powerful and safe tools that use efficient scanning algorithms to repair a damaged SQL Server database. Such applications feature thorough file scanning, non-destructive design, graphically rich user interface and complete documentation.

Inconsistency Assertions 3624 or Error Message 7987 in Sql Server

SQL Server errors are not hostages of only the complex operations, but while the normal and usual operations like SELECT and UPDATE are attempted; several error messages may also be seen. The error messages, as mentioned below,

Resolving SQL Server Error 8942

A SQL Server database table is prone to corruption due to unexpected shutdown, application errors, hardware bugs and similar other faults, thereby resulting into DBCC CHECKDB errors or inaccessible table. To resolve such issues, it becomes essential that you restore from the latest database backup. But sometimes, it is not feasible to restore complete information from the backup. Thus, you should use SQL recovery tools to repair these databases.

As an instance, you might encounter the below error with SQL Server table:

Server: Msg 8942, Level 16, State 1
Table error: Object ID O_ID, index ID I_ID, page P_ID. Test (TEST) failed. Slot S_ID, offset 0xADDRESS overlaps with the prior row.

Cause

The above error occurs due to overlapping of slots. It primarily occurs when the offset of slot S_ID is not equal or greater to previous slot end.

The error is the result of a table test, in which sorted[i].offset has not been found greater or equal to a expected value, ‘max’. Here, ‘max’ signifies the end of last slot and [i] is the ADDRESS.

Solution

To troubleshoot these database table errors, you are recommended to consider these methods:

If you are encountering such problems repeatedly, it might be due to hardware issues. So, you need to diagnose the system, application and SQL Server™ error log to know the exact hardware issues, if any. Remove, swap and replace the damaged hardware.

If this is not a known hardware problem, restore the database from the recent data backup
In cases, when you don’t have any valid data backup, you need to run DBCC CHECKDB command without using any repair clause. This will allow you to determine the exact repair clause required to be applied for database repair.

Next, run DBCC CHECKDB with this repair clause.

Applying the above measure can cause data loss. To perform safe database repair, you should use SQL Repair software. These are perfect tools that apply safe scanning algorithms to result effective repair of complete database and its components. SQL Recovery tools are highly competent utilities with graphically rich user interface.

Rectifying Error 8906 and repairing corrupt database in SQL Server 2000

An IAM (Index Allocation Map) page consists of eight page Ids, collectively called mixed page array, and holds the pages that are allocated to the index. The IAM pages are used to optimize the tables by allocating and deallocating storage space. Sometimes the IAM page is not able to perform as expected. Such corruption instances can occur because of various reasons such as hardware malfunctions, virus infections, power outages, abruptly exiting SQL Server, etc. To resolve such situations, you should use appropriate corrective measures. In case, you are not able to recover SQL database then you should use a third-party SQL database repair software to do so.

Consider a scenario wherein you encounter the following error message while working on an SQL Server 2000 database:

“Page P_ID in database ID DB_ID is allocated in the SGAM SGAM_P_ID and PFS PFS_P_ID, but was not allocated in any IAM. PFS flags ‘PFS_FLAGS‘.”

Cause:

The root cause of this error is that a page that is not reflecting as an IAM page and also not seen in the mixed page array of IAM page. This is quite contradictory as this page has mixed page bit set in its PFS byte.

Resolution:

There could be the following resolutions that you can perform to resolve this error:

Look for hardware problems: You should run hardware diagnostics and check for problems, if any. You can also check the error log report to ascertain whether this error has occurred because of any hardware malfunctions. In addition, you should swap the hardware components to zero down on the cause of error. In the end, you can also consider reformatting the hard disks and reinstalling the operating system to get a fresh operating system.

Restore from backup: After confirming that this is not a hardware related error, you should check the backup of the database. If it is updated and clean, then you should restore the database from the backup.

Run DBCC CHECKDB: If none of the previous methods work, then you should run the DBCC CHECKDB command without any repair clause to know the level of corruption. Then, you should run it again with the recommended repair clause.

The aforementioned methods should repair the corrupted database. However, if you still encounter the same error again then you should use a third-party SQL database recovery software to do the needful. Such read-only tools perform SQL recovery without overwriting the existing database.

Rectifying Error 2578 and recovering corrupted database in SQL Server 2000

Are you facing problems while working on your SQL Server 2000 database? Are you getting lot of error messages for some tasks that worked fine previously? Or the database is responding too slowly? If all your answers are in YES, then chances are that the database has corrupted. It may have corrupted due to various reasons such as virus infections, power outages, hardware malfunctioning, etc. To resolve such issues, you can perform in-place resolving techniques. If you are not able to address the situation, then you should use a third-party SQL database repair software to repair SQL database.

Consider a scenario wherein you encounter the following error message while working on the SQL Server 2000 database:

“Minimally logged extents were found in GAM interval starting at page P_ID but the minimally logged flag is not set in the database table.”

Cause:

The root cause of this error is that a page of ML_MAP_PAGE was found in the GAM extent. However, in the DBTABLE, the DBT_MINIMAL_LOG_IN bit was not set.

Resolution:

To resolve this error, you need to recover SQL database. To do this, perform the following methods preferably in the given order:

Resolve the hardware issues: You should run hardware diagnostics and check if the problem is because of any faulty hardware component. You can also check the error logs to ascertain this. In addition, you can swap the hardware components to zero in on the actual cause of the problem. If nothing works out, then you can reformat the hard disks and reinstall the operating system to get an altogether fresh system.

Restore from backup: If the problem is not hardware related, then you should check if the backup is clean and updated. If yes, then restore the database from its backup.

Use DBCC CHECKDB: As a last resort, you should run the DBCC CHECKDB command: first without any repair clause to know the extent of corruption and then with the suggested repair clause.

After performing the aforementioned methods, check if you are still getting the same error. In most of the cases, it would not. However, if the error is still not resolved then you should use a third-party SQL database recovery software.

“Object ID O_ID, forwarded row page P_ID1, slot S_ID1 should be pointed to by forwarding row page P_ID2, slot S_ID2. Did not encounter forwarding row. Possible allocation error.”

Cause:

The root cause of this erroneous situation is that there is a forwarded row in a heap that is missing the forwarding row that should point to it.

Resolution:

To resolve this problem, you need to do MDF file recovery. For this, you should perform the following methods:

Check for hardware issues: You should check the hardware components to ascertain whether the error has occurred because of any hardware malfunctions or not. You can also swap the hardware components to isolate the actual problem. Last but not the least, you can even consider reformatting hard disks and reinstalling operating system.

Restore from backup: If it is not a hardware related problem, then you should check the backup of the database. If it is updated and clean, then you should restore the database with its backup.

Run DBCC CHECKDB: If the database is not clean, then you should run DBCC CHECKDB command with the suggested clause to repair the corrupted database. It will convert the forwarded row into a regular data row.

These methods should be able to repair the corrupted SQL component. However, if you are still getting the same error, then you should use a third-party SQL database recovery software to perform SQL recovery.
