CSDBKUP
The CSDBKUP parameter specifies whether or not the CSD is eligible for BWO.
- CSDBKUP={STATIC|DYNAMIC}
- If you want to use BWO, specify CSDBKUP=DYNAMIC. The CSDBKUP, CSDRECOV, and CSDFRLOG system initialization parameters interact according to how they are specified. For information about their effects when the SIT is assembled and during CICS override processing, see Planning for backup and recovery.
- STATIC
- All CICS files open for update against the CSD data set must be quiesced before a DFHSM and DFDSS backup of the CSD data set. The files must remain quiesced during the backup.
- DYNAMIC
- DFHSM and DFDSS are allowed to make a data set back up copy while CICS is updating the CSD.
Note that CSDBKUP=DYNAMIC is valid only if you have also specified CSDRECOV=ALL.
