Format of DBCTL operator commands

DBCTL commands begin with a command recognition character (CRC). A CRC of / is the default. (The examples of DBCTL commands in this manual use the default CRC.) You can override it on the DBCTL job, but remember that each DBCTL subsystem in a single MVS image must have a different CRC. This CRC must also be different from every other subsystem in the processor (or multiprocessor), not just DBCTL subsystems. The same applies to any test systems you might be using. You can, if you prefer, use the subsystem ID (for example, SYS1) of the DBCTL you are using instead of a CRC.

There must be no space between the CRC and the verb. Usually there is a space between parameters, except as noted for specific parameters in Operations and automation in IMS product documentation. Many verbs and keywords have abbreviations. Guidance on using them is in Operations and automation in IMS product documentation.
