JES2 waits have the same symptoms as MVS™ waits.

Use SYSLOG to determine the cause of the wait. If you determine that JES2 is the cause of a wait state, ensure that you dump JES2 by entering the following command from a console with master authority:

DUMP COMM=(JES2 HANG DURING INITIALIZATION)

The system will respond with the message:

* id IEE094D SPECIFY OPERAND(S) FOR DUMP COMMAND

Waits can be caused by resource shortages. See Resource shortages for additional information.
