An insight into MS SQL Server 2005 enhancements, inconsistencies and some appropriate resolution measures

The primary feature that distinguishes MS SQL Server 2005 from the earlier versions is its best in-class security enhancements. It allows you to categorize users into groups and grant adequate permissions to each group in order to keep your highly confidential data secure. You can have a dedicated administrator connection, which surely eliminates the need to stop the SQL Server service at the time of a failure. Moreover, the new database mirroring feature ensures high data availability and safety. Despite providing users a reliable database management platform, it certainly has a few inconsistencies. An SQL database is subject to corruption and some of the primary reasons for this corruption include virus infection, hardware failure, operating system malfunction, abnormal shutdown, etc. As a consequence, you might come across serious data loss. To overcome this problem, you need to go for MS SQL recovery through a reliable third-party utility.

Suppose, you have MS SQL Server 2005 installed in your system. You may encounter the following error message while using one of your important databases:
“Table error: Object ID O_ID, index ID I_ID, partition ID PN_ID, alloc unit ID A_ID (type TYPE). Duplicate keys on page P_ID1 slot SLOT1 and page P_ID2 slot SLOT2.”

The above error occurred because two slots on two different database pages contain the same or identical keys, including any uniqueifiers. You may encounter such situation in the event of a database corruption.

This would usually lead to inaccessibility of various database components. You may use an updated or recent backup to restore your troubled database. However, if the backup is missing, you should follow the below mentioned resolution steps.

To resolve the problem, you need to perform the following steps:

• Verify Windows system and application log and the SQL Server error log and check for a hardware failure. If there is a hardware-related problem, run hardware diagnostics or try replacing the damaged hardware component.
• If there is a logical corruption, run DBCC CHECKDB with an appropriate repair clause.

If the problem still persists, you should take help of a proficient SQL database recovery utility. These third-party tools follow a simple, streamlined procedure to repair corrupt MS SQL databases and restore vital database objects with their exact properties and attributes. They enable you to save the recovered queries, views, stored procedures, etc. in a separate text file. Moreover, they are compatible with Windows 7, Server 2008, Vista, Server 2003, XP, and 2000.
