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.
