Setting system parameters

In WebSphere MQ for z/OS, a system parameter module controls the logging, archiving, tracing, and connection environments that WebSphere 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 WebSphere MQ for z/OS. If these do not contain the values that you want to use, you can create your own parameter modules using the sample supplied with WebSphere MQ. The sample is thlqual.SCSQPROC(CSQ4ZPRM).

You can alter some system parameters while a queue manager is running. See the SET SYSTEM, SET LOG and SET ARCHIVE commands in the WebSphere MQ Script (MQSC) Command Reference.
