subject: Tips To Resolve table Error: Iam Chain Linkage Error... Error Message [print this page] IAM (Index Allocation Map) pages in SQL Server database tracks nearly 4GB file space to store critical Extent information belonging to a particular entity. These IAM pages are have to be linked together in case an entity needs many IAM pages to track all the Extents. The linking of all IAM pages is termed as IAM chain. Corruption or damage in IAM chain can occur due to unexpected shutdown of SQL Server, metadata structure corruption, operating system damage, and virus hit. In most of these situations, the database becomes unmountable making all the records saved in it inaccessible. A complete and updated database backup acts as a boon by restoring all the records. However, in case of database backup unavailability or backup falling short to restore the required data, start searching for an advanced third-party sql database repair application.
