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.

Windows Unable to Start SQL – Error 10022 Displaying

There are two basic components of the MS SQL Server and they are the ‘data files’ and ‘transaction log files’. The latter i.e. the transaction log files record uncommitted transactions of the databases. A situation unfortunately possible to arise is of SQL corruption which brings with it the by-products, data loss and halt of work. These by-products buy immense tension, worry and distress for the users because it is their days and days of endeavor and also, SQL corruption would mean the halt of many important tasks that were being carried out with the help of MS SQL. Sometimes, the user sees error 10022. An SQL repair tool that will fix SQL database 10022 error to resume the proper and normal functioning of SQL Server would be the only and most workable solution to deal with this problematic situation.

The SQL Server can unpredictably shut down due to some unanticipated reason. After this, when the user restarts the Server, it analyzes transaction log files and if they are not committed, then the alterations and changes which were performed as a part of those transactions are rolled back. But sadly, at times, this recovery process does not finish successfully leaving the database in a corrupted state. In such a scenario, it is required on the part of the user that he gets the restoration done from the last good backup. But more sadly, if no such backup is present or is damaged, then simply a single sql recovery solution is left with him which is to use an SQL server recovering tool for restoring SQL database.

Sometimes when the installation of SQL Server application gets corrupted, it shows the following error message:
“Windows could not start the SQL Server on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code 10022″.

After getting this error, a user should first of all try to find the actual cause of it. There are very simple ways to find this cause:

By trying to bypass Configuration Manager which can be done by starting the MS SQL Server from the Windows Services applet. The user can do this through command prompt also. It is possible that after the user runs the command, he gets an error message saying: “Your SQL Server installation is either corrupt or has been tampered with (Error getting instance ID from name.). Please uninstall then re-run setup to correct this problem” which is a signal of huge trouble. When the user re-installs the application it may or may not solve the problem, and even worsen it by damaging or corrupting the database leading to the corruption of the MDF files. In this condition, an SQL repair tool is imperative. User can also go for editing of the registry entries. It needs locating of the following: HKEY_LOCAL_MACHINESOFTWAREMicrosoftMicrosoft SQL Server.

If there are some permission problems, they can be corrected it.

Resolving Error 7965 and recovering corrupt database in SQL Server 2000

In SQL Server databases, an Index Allocation Map (IAM) page is a page type that stores the details about the extents, which is a collection of eight pages. These IAM pages are used to navigate through the heap, thereby making the searching process much faster. Well, at times these IAM pages do not exhibit the desired working due to database corruption. Database corruption can occur due to various reasons such as power outages, human errors, damaged hardware components, virus infections, etc. You should find out the cause and the resolution to recover SQL database. If you are not able to recover the database, then you should use a third-party SQL database recovery software to do the needful.

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

“Table error: Could not check object ID O_ID, index ID I_ID due to invalid allocation (IAM) page(s).”

Cause:
The root cause of this error message is that one of the IAM pages, which was identified by various Ids, has corrupted.

Resolution:
To resolve this erroneous situation, you should recover SQL database using the following methods, in the given order:

Check the hardware-related reasons: You should check the error log reports to check whether the error has occurred due to malfunctioning hardware components. You can also consider swapping the hardware components to isolate the actual reason for error. You may also consider reformatting the hard disks and reinstalling the operating system to get a fresh system to work on.

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

Run DBCC CHECKDB: If the backup is not updated, then you should run the DBCC CHECKDB command to repair the database. You should run it without any repair clause to know the level of corruption, and then with the recommended repair clause to repair the database.

However, if the problem is not resolved even after performing these methods then you should use a third-party SQL database recovery software. These read-only tools are able to recover SQL database without overwriting the original database.

3403 Error in SQL – Combat Data Loss with SQL Repair Tool

The SQL Server comprises of two fundamental elements; one is the “data files” and the other is the “transaction log files.” It is the transaction log file that records databases’ uncommitted transactions. Sometimes a problem arises when SQL Sever service unexpectedly shuts down to any unpredictable reason. After this accidental shut down, when the user tries to restart the server again, it analyzes all the SQL transaction log files. Now, if the transactions are not committed, then the changes that were performed as a part of those transactions are rolled back. But unfortunately, sometimes, this process of recovery does not successfully ends and thus leaving the database in the corrupted state only. In such situation, the user requires restoration from the last good backup. But, if no such backup is there or is damaged, then the only solution left with the user is to use an SQL database recovery tool for repairing MDF files which is the most apt and wise way for SQL database repair.

The error 3403

During the SQL Server database corruption, the user encounters the below error message:

Error 3403, Severity 22 During recovery initialization, page %ld was encountered. This page belongs to object %ld, not the log

Cause of SQL Server error 3403

When the MS SQL Server crashes, it itself tries to recover without user intervention. When this automatic recovery takes place, there happens a complete scan of transaction logs up till the last page. If a page is found which is allocated to syslogs but the page header object ID does not match with that of syslogs, in that case, error 3403 is displayed and recovery is failed. Recovering SQL server database using an outside solution for SQL database 3403 error fix is the only way out of this problem. Such recovery is not difficult with a highly reliable SQL repair tool by SysTools for restoring SQL server databases from .mdf files.

Reasons for such error display

Failed SQL recovery and display of 3403 error occurs due the following plausible reasons:

An SQL server problem resulting in a bad write or page allocation The user updates the allocation page and SQL Server goes down prior to the writing of the transaction log page. So, on the time of automatic rebuilding of SQL database, it happens without the clearing of the transaction log pages and the old log entries still existing.

Solution for SQL database recovery

This situation can be dealt by checking the backup status. If there is an existence of a clean backup, then one should drop the damaged or corrupted database and should load it from the backup. But, in the case where no backup exists, the user should use professional help from a good SQL recovery application for repairing MDF files.
