Queues

Job and Print Queue Names—The default Work Management names QPRINT, QBATCH and QPGMR should be used where possible, and object identification controlled by library list. Consider introducing a different output queue for each forms type used.

Message Queues—Display device message queues (created automatically by OS/400) will be given the same name as the associated device. OS/400 will also automatically create a message queue for each user profile. Other message queue names should describe their role. For example, ‘NGHTERRMSG’ - error messages from the overnight batch run.

Message queues can be particularly useful for providing log functions. For each application system, consider introducing three message queues (xxxSYSOPR, xxxHSTLOG, and xxxCHGLOG), each with a particular role:

• An exception message queue to contain information about errors and exceptions. This is analogous to the OS/400 QSYSOPR message queue.
• A log message queue to contain audit information recording important processing stages; for example, end of period processing.
• An object change log message queue. The CA 2E Toolkit Move object (YMOVOBJ) and Move object & source (YMOVOBJSRC) commands may be used to send messages automatically to this log to record object changes when objects are moved into the live system.
