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.

Damaged and Deleted SQL Data Recovery after GAM Page Error

Allocation Units in SQL: In Microsoft SQL Server, the database is basically divided into different allocation units, viz. Index Allocation Map or IAM pages, Global Allocation Map or GAM pages, Shared Global Allocation Map or SGAM, and or Page Free Space or PFS pages. All of these allocation units are required to be in healthy condition for the successful functioning of your MS SQL database. However, corruption in any of these allocation units or pages can result in stopping SQL database mounting; thereby, resulting in the inaccessibility of databases elements like tables, views, stored procedures, indexes, triggers, etc.

GAM Page Error: A common database damaging situation occurs when the GAM allocation page falls prey to corruption, making your SQL database elements inaccessible to you. The error message that you will see on your screen can be: Page errors on the GAM… The error message that will appear whenever you attempt to mount your database will be: “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.” Same message appears repetitively each time you try to mount your SQL database.

Possible Reasons for GAM Page Error: The above-written error message can occur either because of some logical or physical damage. Various factors can be responsible for such corruption in SQL Server allocation pages. Naming a few of them – wrong system or application shutdown, MS SQL Server damage, Trojan infections or virus attacks on the system, software malfunctioning, human errors, media errors, etc. However, in the above situation, the major possibility of damage is due to the corruption in any of GAM, SGAM, or PFS pages of SQL database Server Meta structure.

Useful Resolution Points: For resolving the issue and for regaining access to your SQL database elements again, you can do the following measures:

* If corruption has occurred due to physical damage, then you must replace that system component which is damaged by a new component
* However, if the problem is as a result of some logical damage, then you can run the ‘DBCC CHECKDB’ command with correct repair clause
* In case above resolutions fail, try to restore your damaged or deleted SQL database from an updated backup

In however, you had forgotten to update backups; then an SQL database recovery tool is what you need to rescue your database in an efficient manner. One such useful tool for damaged or deleted SQL data recovery is SysTools SQL Recovery software. SQL data recovery using this SQL database recovery software is extremely simple.

Repairing SQL Server master database – Error 3417

SQL Server is a relational database management system (RDBMS) by Microsoft that is designed for the enterprise environment. It has got two primary query languages, T-SQL and ANSISQL. It provides you the flexibility to access your database from anywhere, be it from a data center, desktop, or from a mobile device. It also provides combined services to query, search, synchronize, report, and analyze the database records. However, at times it may happen that the SQL Server is unable to run. It may be possible that the master database has gone corrupt. This can be possible because of various reasons such as virus infections, human errors, power outages or abrupt system shutdown while SQL Server was open. In such cases, you should replace the corrupted database with its updated backup.
