Database exception table records
Database exception table (DBET) log records register different types of information: exception states and image copies of special table spaces.
DBET log records also register exception information
that is not related to units of recovery.
Exception states
DBET log records register whether any database, table space, index space, or partition is in an exception state. To list all objects in a database that are in an exception state, use the command DISPLAY DATABASE (database name) RESTRICT.
Image copies of special table spaces
Image copies of DSNDB01.SYSUTILX, DSNDB01.DBD01, DSNDB06.SYSTSCPY,
and DSNDB01.SYSDBDXA are registered in the DBET log record rather
than in SYSCOPY. During recovery, they are recovered from the log,
and then image copies of other table spaces are located from the recovered
SYSCOPY.
