WebSphere MQ work management objects

When WebSphere MQ is installed, various objects are supplied in the QMQM library to assist with work management. These objects are the ones necessary for WebSphere MQ jobs to run in their own subsystem.

Sample job descriptions are provided for two of the WebSphere MQ batch jobs. If no specific job description is provided for a WebSphere MQ job, it runs with the default job description QMQMJOBD.

The work management objects that are supplied when you install WebSphere MQ are listed in Table 2 and the objects created for a queue manager are listed in Table 3

Note:
The work management objects can be found in the QMQM library and the queue manager objects can be found in the queue manager library.
