Fixing “Multiple IAM Pages For Object” Error Message
MS SQL Server database data files are divided into numerous GAM (Global Allocation Map) intervals. Each GAM interval consists of at least 4GB space or 64,000 extents. The page interval allocates one or more pages to an index that contains an IAM (Index Allocation Map) page for that GAM interval. However, the problem occurs when the index contains more than one IAM page for a GAM interval. The above situation primarily occurs when the SQL Server database gets corrupted or damaged. To overcome such database corruption scenarios, an easy way followed by most of the database users is restoration from an updated backup. However, in case of unavailability of a valid backup, you need to use advanced MS SQL Recovery application.
Consider a practical case, where you attempt to access the records saved in one of your tables. Instead of viewing the table records, you receive the below error message:
“Table error: Multiple IAM pages for object ID O_ID, index ID I_ID contain allocations for the same interval. IAM pages P_ID1 and P_ID2.”
The same error message pops up every time you attempt to access the database table records. Additionally, the records saved in the database table become inaccessible after the above error message pops up.
Cause:
The reason for the occurrence of the above error message is that there are two IAM pages (P_ID1 and P_ID2) that cover the same GAM interval. This occurs either due to physical or logical corruption of the database.
Resolution:
To resolve the above error message and to access the database table records, you need to repair the database using below methods:
Change the damaged/corrupt system component to isolate the physical damage reasons.
Run DBCC CHECKDB command (with repair clause) to isolate all logical corruption scenarios.
If the problem persists, then you need to repair the database using an advanced SQL Database Recovery software. A SQL Repair application repairs corrupt database in all cases of logical corruption.
SQL Recovery is a trust-worthy solution for resolving all sorts of corruptions in SQL database. The software brings the database in a re-usable state in three simple clicks. Compatible with SQL Server 2008, 2005, and 2000, the SQL Repair tool saves the repaired database at required location. It is designed for Windows 7, Vista, 2008, XP, 2003, and 2000.
