Configuring system parameters on z/OS queue managers
If the default system parameter module that is supplied with IBM® MQ does not contain the system parameters that you want, you can create your own system parameter module and customized macros.
About this task
A subset of a z/OS® queue manager's attributes are loaded from the queue manager's system parameter module when the queue manager starts. The default system parameter module that is supplied with IBM MQ is called CSQZPARM. In the system parameter module are three macros:
- CSQ6SYSP, which controls the connection and tracing parameters
- CSQ6LOGP, which controls log initialization
- CSQ6ARVP, which controls archive initialization
If the default system parameter module does not contain the system parameters that you want, you can create your own system parameter module and customized macros using the supplied JCL sample. You cannot perform these customizations from IBM MQ Explorer because IBM MQ Explorer cannot connect to a queue manager that is not running. For more information, see Customizing your queue managers in the IBM MQ online product documentation.
Viewing the system parameters
When the z/OS queue manager starts, it loads its system parameter module which sets the queue manager's initial system parameter values. When the queue manager is running, you can monitor and administer it from IBM MQ Explorer and, therefore, view the queue manager's initial system parameter values.

Overriding system parameters while the queue manager is running
While the queue manager is running, you can change and temporarily override certain system parameter values. You can make these changes from IBM MQ Explorer.
