Naming convention

The DBCTL display commands (for example, /DISPLAY ACTIVE and /DISPLAY CCTL). and the DRA startup table USERID parameter, all use what is known in IMS and DBCTL as the CCTL ID to identify the transaction management subsystem. In the case of CICS®, the CCTL is CICS and the ID is the CICS APPLID.

However, many IMS messages use the jobname of the CICS system instead. An example of this sort of message is DFS554, which notifies you that a BMP region, or a thread from a CICS transaction, has terminated abnormally. If the DFS554 message was caused by an abnormal termination of a thread that originated from CICS, the message text contains the CICS job name or CICS startup procedure name. You will therefore need a naming convention that enables operators to immediately identify a corresponding CICS APPLID and CICS JOBNAME. For example, if you use the APPLID DBDCCICA, your job name could also contain the characters CICA.
