Transient data definitions

CICS provides a resource definition for the CICS® ONC RPC message transient data queue CRPO. The resource definition is in group DFHDCTG, which is part of DFHLIST.

Group DFHDCTG is not protected by a lock, so the definitions it contains can be modified if required. CRPO is defined as an extrapartition queue, but you can make the destination intrapartition or indirect if you prefer.

If you leave CRPO defined as an extrapartition queue, you must add a suitable DD statement for the extrapartition queue in the CICS JCL, for example:

//CRPO   DD   SYSOUT=A
