The PFS (Page Free Space) pages in the MS SQL Server databases are used to search for free space in the database tables. It holds a byte-map which contains one byte per page that is represented by P_ID. Sometimes, you are unable to read the PFS page that can happen due to database corruption. The corruption cases are caused due to various issues such as abrupt or improper system shutdown when the database is open, virus infections, etc. In such circumstances, you should try to recover SQL database using appropriate methods. If you are unable to workaround the issue, then you should use a third-party SQL database recovery software to address the problem.

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

"Object ID O_ID, index ID I_ID: Page P_ID could not be processed. See other errors for details."

Cause:

The most prominent cause of this problem is that the P_ID page was marked as allocated in a PFS page. But, when the page was read, the reading failed resulting in this error...

In the MS SQL Server databases, the IAM (Index Allocation Map), GAM (Global Allocation Map), SGAM (Shared GAM) are different types of pages that are used to store the records on the hard disks. These pages combine together in an extent, which is used to hold the metadata of the databases. A lot of times due to the mismatching in these files, the database gets corrupt and does not work properly. In such cases, you should try to repair MDF file using appropriate measures. However, if the problem is not addressed, then there is a strong case of using a third-party SQL repair software.

Consider a situation in which you are facing the following error message while working on an MS SQL Server 2000 database:

“Extent E_ID in database ID DB_ID is allocated in both GAM GAM_P_ID and SGAM SGAM_P_ID.”

Cause:

The error has occurred because of corruption in the extents due to the irregularities in the IAM, GAM, and SGAM pages.

The system catalogs in SQL Server databases are used to store various types of information such as number and names of tables and views in the database among many others. This information is collectively referred as metadata. However, sometimes this metadata may get corrupt due to various reasons such as virus infections, hardware issues, power outages, etc. In such cases, you should use the in-place methods to rectify the problem. However, if you are not able to recover SQL database, then you should use a third-party Repair SQL database software to do the needful.

Consider a scenario wherein you encounter the following error message while using the DBCC CHECKNAME tool on an SQL Server 2008 database:

"Database 'DBNAME': consistency errors in system catalogs prevent further DBCC CHECKNAME processing."

Cause:

There could be the following causes for this error. They are:

The system base tables are storing the metadata for all the objects in the database...

As you store more and more data to your Microsoft SQL Server database, the size of database increases and the performance of Microsoft SQL Server decreases day by day. Large size of database may also cause system crash and sometimes database corruption. To prevent such situations, MS SQL Server provides SHRINKFILE and SHRINDB tools for reducing size of the database. However, in some cases, these tools fail to shrink the database and problem remains intact. At this point, if database corruption occurs, SQL database repair becomes need of hour.

As a practical example of this behavior, you may come across the following error message when you try to reduce size of the SQL Server 2000 database using SHRINKFILE, SHRINKDB, or SQL Server Enterprise Manager:

"2002-11-25 22:41:30.18 spid55 Time out occurred while waiting for buffer latch type 4,bp 0x3d03340, page 1:37939357), stat 0xb, object ID 8:8:0, EC 0xB39B55E0 : 0, waittime 300. Not continuing to wait...

MS SQL Server 2000 is used to provide enterprise solution in many reputed organizations. The primary reasons behind this are that it is simple to use, scalable for huge databases, provides strong support for demanding situations, etc. However, having said that, the database tables may sometimes become corrupt thereby disabling you to use it properly. Such issues can occur due to virus infections, power outages, damaged hardware components, etc. You should inquire for the cause of the corruption and try to recover SQL database. If you are not able to resolve the issue, then you should use a third-party SQL database recovery software to perform SQL server recovery.

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

"Table error: Object ID O_ID, Index ID I_ID. Duplicate keys on page P_ID1 slot SLOT1 and page P_ID2 slot SLOT2."

Cause:...

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:...

Microsoft usually recommends you to use a SAN (Storage Area Network) or locally attached hard drives to store your MS SQL Server database (MDF or Master Database File) because it optimizes the reliability and performance of Microsoft SQL Server. Use of the network database files (the files stored on NAS [Network Attached Storage] or networked server) isn't enabled for MS SQL Server. However, this configuration may damage your SQL Server database in some cases of system failure. In such situations, you must have an absolute backup of your significant database to extract inaccessible data from it. In the other case, you need to go for master database file recovery solutions to get your valuable data back.

Although, network file support is not enabled by default in Microsoft SQL Server, you can manually configure MS SQL Server to store all your database files on NAS storage server or networked server. The servers, which you employ for this configuration, must fulfill MS SQL Server requirements for write-through guarantees and data write ordering...

The tempdb database is one of the system databases in SQL Server. It is used to store the temporary tables, table variables, etc. The tempdb is recreated every time SQL Server is started. This way, the system always starts with a fresh copy of the tempdb database. However, sometimes the tempdb gets corrupt because of various issues such as power outages, virus infections, human errors, abrupt system shutdown, etc. In such cases, you should take appropriate corrective measures to resolve the issue. However, if you are not able to do so then you should use a third-party MS SQL repair tool to repair SQL database.

Consider a scenario wherein you are performing allocation checks on the tempdb database. But the process terminates abruptly and an error message is displayed, that is: “Database tempdb allocation errors prevent further CHECKNAME processing.”

Cause:...
