Task 13: Customize the initialization input data sets

 

• Repeat this task for each WebSphere MQ queue manager.

• You need to perform this task when migrating from a previous version. For details, see Migrating from a previous version.

Each WebSphere MQ queue manager gets its initial definitions from a series of commands contained in the WebSphere MQ initialization input data sets. These data sets are referenced by the DDnames CSQINP1 and CSQINP2 defined in the queue manager started task procedure.

Responses to these commands are written to the initialization output data sets referenced by the DDnames CSQOUT1 and CSQOUT2.

Sample initialization input data sets are supplied with WebSphere MQ, see the WebSphere MQ for z/OS Concepts and Planning Guide for information about them.

To preserve the originals, you should make working copies of each sample. Then we can tailor the commands in these working copies to suit your system requirements.

If you use more than one WebSphere MQ subsystem, you are recommended to include the subsystem name in the high-level qualifier of the initialization input data set name. This allows you to identify the WebSphere MQ subsystem associated with each data set more easily.
