DB2 initialization

The initialization phase verifies BSDSs, logs, and the integrated catalog facility catalog.

In this phase, the RBA of the last log record is retrieved, and logging is set to begin at the next control interval (CI) following the last RBA. Also during this phase, DB2® determines if the lock structure or SCA is lost and needs to be recovered.

The following message output shows a group restart controlled by member DB3A on behalf of members DB1A and DB2A. During initialization, you see messages similar to the following messages:
