Defining the system on z/OS
IBM MQ for z/OS uses many default object definitions, and provides sample JCL to create those default objects. Use this topic to understand these default objects, and the sample JCL.
Set system parameters
In IBM MQ for z/OS, a system parameter module controls the logging, archiving, tracing, and connection environments that IBM MQ uses in its operation. The system parameters are specified by three assembler macros, as follows:
- CSQ6SYSP
- System parameters, including setting the connection and tracing environment.
- CSQ6LOGP
- Logging parameters.
- CSQ6ARVP
- Log archive parameters.
Default parameter modules are supplied with IBM MQ for z/OS. If these do not contain the values that we want to use, we can create your own parameter modules using the sample supplied with IBM MQ. The sample is thlqual.SCSQPROC(CSQ4ZPRM).
We can alter some system parameters while a queue manager is running. See the SET SYSTEM, SET LOG, and SET ARCHIVE commands in The MQSC commands.
