Fine tuning a system parameter module

WebSphere MQ also supplies a set of three assembler source modules, which can be used to fine tune an existing system parameter module. These modules are in library thlqual.SCSQASMS. Typically, you use these modules in a test environment to change the default parameters in the system parameter macros. Each source module calls a different system parameter macro:

This assembler source module... Calls this macro...
CSQFSYSP CSQ6SYSP (connection and tracing parameters)
CSQJLOGP CSQ6LOGP (log initialization)
CSQJARVP CSQ6ARVP (archive initialization)

This is how you use these modules:

  1. Make working copies of each assembler source module in a user assembler library.

  2. Edit your copies by adding or altering the values of any parameters as required.

  3. Assemble your copies of any edited modules to create object modules in a user object library.

  4. Link-edit these object code modules with an existing system parameter module to produce a load module that is the new system parameter module.

  5. Ensure that new system parameter module is a member of a user authorized library.

  6. Include this library in the queue manager started task procedure STEPLIB. This library must come before the library thlqual.SCSQAUTH in STEPLIB.

  7. Invoke the new system parameter module by issuing a START QMGR command, specifying the new module name in the PARM parameter, as before.
