An i5/OS™ job is routed to a subsystem by using the routing entries in the subsystem description. The routing entry for the listener job in the QSYSWRK subsystem is present after i5/OS is installed. This job is started under the QUSER user profile, and the QSYSNOMAX job queue is used.
Prior to V5R2, the server jobs ran in the QSYSWRK subsystem. In V5R2, the server jobs run by default in QUSRWRK. The characteristics of the server jobs are taken from their prestart job entry which also comes automatically configured with i5/OS. If this entry is removed so that prestart jobs are not used for the servers, then the server jobs are started using the characteristics of their corresponding listener job.
The following list provides the initial configuration in the QSYSWRK subsystem for the listener job.
