$HASP9211

hh:mm:ss.xx

Explanation

>>-JES MAIN TASK NOT RUNNING--DURATION---hh:mm:ss.xx-----------><

 JES2 issues this message in response to a
$JDJES or a $JDSTATUS monitor command or as a highlighted message.
Based on context, this message can indicate an alert or an incident
JES2 is tracking. This message is issued when the JES2 main task has
been waiting at its normal wait for the duration specified. There
are indicators that the main task does have work to do and should
be running, but it is not.
 In the message text: hh:mm:ss.xx
The length of time the main task has been waiting at its normal z/OS® wait.

System action
 If the condition persists, JES2 reissues this
message every 30 seconds with updated information.

Operator response
 Monitor alerts indicate potential reasons
why JES2 is not functioning properly. If this condition persists,
notify your system programmer.

System programmer response
 JES2's main task might not be running
because of improper tuning of MVS™ parameters or because of a problem
in the JES2 address space. If the condition persists, investigate
tuning and operational considerations first. For example, consider
if online applications have been tuned to run before JES2 (not a recommended
practice), or if the operator has issued a command that requires heavy
use of system resources.
 If the condition persists after investigating
a tuning or operational issue, obtain a dump of the JES2 address space
and determine why the JES2 main task is not being dispatched. Common
problems include the following: A service or an exit has reset the main task STIMER so that the
main task is not "waking up."
A POST SRB  is unable to run because the local lock is not available.
Determine which function is holding the local lock and why.

If the problems appear to be in IBM-distributed code, contact
the IBM® support center. Restarting JES2 might correct
the problem, however, if the condition is a result of tuning, attempting
to restart JES2 can aggravate the condition.
