Default system examples for IBM i

These examples show how an unmodified IBM® MQ installation works when some of the standard jobs are submitted at queue manager startup time.

First, the AMQZXMA0 execution controller job starts.

Issue the STRMQM command for queue manager TESTQM.
IBM MQ searches the queue manager library QMTESTQM, firstly for job description AMQZXMA0, and then job description QMQMJOBD.
Neither of these job descriptions exist, so IBM MQ looks for job description AMQZXMA0 in the product library QMQM. This job description exists, so it is used to submit the job.
The job description uses the IBM MQ default job queue, so the job is submitted to job queue QMQM/QMQM.
The routing data on the AMQZXMA0 job description is QMQMRUN20, so the system searches the subsystem routing entries for one that matches that data.
By default, the routing entry with sequence number 9900 has comparison data that matches QMQMRUN20, so the job is started with the class defined on that routing entry, which is also called QMQMRUN20.
The QMQM/QMQMRUN20 class has run priority set to 20, so the AMQZXMA0 job runs in subsystem QMQM with the same priority as most interactive jobs on the system.
