Automatic index recovery to rebuild

Automatic index recovery to rebuild is a strategy in which the solution identifies indexes that have copies and recovers them when possible. If no copy exists or the index is not recoverable, the solution automatically falls back to an index rebuild.

The BMC Recovery Management for Db2 solution supports this strategy through both the BMC AMI Recovery Manager and BMC AMI Recover components. This feature is most powerful when used in conjunction with the automatic index backup feature (see Making-automatic-index-copies).

BMC AMI Recovery Manager supports the automatic index recovery-to-rebuild strategy by default. ARMBGEN generates syntax which tells BMC AMI Recover to fall back to REBUILD for unrecoverable indexes.

For automatic backout recoveries (BACKOUT AUTO), BMC AMI Recovery Manager generates the INDEXLOG AUTO statement in the JCL to enable BMC AMI Recover to automatically recover or rebuild indexes.
