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.
