The CSDDISP parameter
specifies the disposition of the data set to be allocated to the CSD.
- CSDDISP={OLD|SHR}
- If no JCL statement for the CSD exists when it is opened, the
open is preceded by a dynamic allocation of the CSD using this disposition.
If a DD statement exists in the JCL of the CICS startup job, it takes
precedence over this disposition.
- OLD
- The disposition of the CSD is set to OLD if dynamic allocation
is performed.
- SHR
- The disposition of the CSD is set to SHR if dynamic allocation
is performed.
This parameter is effective only on a CICS cold
or initial start. On a warm or emergency restart, file resource definitions
for the CSD are recovered from the global catalog.
