The HDB(HKEEP) operand requests CICS PA to perform
housekeeping on the HDB Register (DDname CPAHDBRG). Housekeeping
deletes expired HDB container data sets and removes definitions from
the HDB Register that are no longer required.
The command format is:
CICSPA HDB(HKEEP)
Note: There is a second function available in HDB housekeeping, Repair
HDB Register using VERIFY command. This is available only from
the CICS PA dialog.
