DBRC considerations for Initializing a DEDB
DBRC setting for the initialization function
Recovery Needed flag
Exclusive access (EX)
If your areas do not reflect the appropriate Recovery Needed condition, their status must be changed before execution of the initialization function. To set the Recovery Needed flag ON, execute the DBRC utility by using the command shown in the following figure.
DBRC command for setting the Recovery Needed flag on
CHANGE.DBDS DBD(dbdname) AREA ( areaname1) RECOV
Multiple area data sets (MADS) are not supported. The initialization function initializes only the first area data set that is registered in the ADS list (in collating sequence by DD name). All other area data sets are marked unavailable. After initialization processing has completed, use the IBM Online MADS Create utility to initialize the other (unavailable) area data sets.
When initialization processing is completed, the initialization function resets the Recovery Needed flag.
The initialization process also creates a REORG record in DBRC, if DBRC detects that this record is required for recovery.
