IBM® ships the QSERVER/QUSRWRK subsystems to use prestart jobs to improve performance at job initialization and startup.
When prestart jobs are configured in the subsystem, the job MUST be active to connect. The prestart job used for a TCP/IP connection is:
To verify a prestart job is running use one of the following:
WRKACTJOB SBS(QUSRWRK)
WRKACTJOB SBS('user-defined-subsystem')
The appropriate prestart job should be active:
Job User Type -----Status-----
QZDASOINIT QUSER PJ ACTIVE (socket connection)
Prestart jobs do not display in WRKACTJOB unless a connection is already active. You must use F14 - Include from the WRKACTJOB panel.
