George, I had opened a service request with MQ support a while back over the changed behaviour of CSQOREXX at 5.3. The change is that CSQOREXX now reacts to JWT where prior to 5.3 is seemed to not be affected by JWT. Here is part of the reply I got:
"The different behaviour of CSQOREXX is due to changes to the batch stub. In the past the batch stub has employed a STIMER exit to check for Queue Manager termination which if detected would post all get waiters. In V5.3 this function is only used for Get with Signal, Get with wait now employes a ECB/WAIT mechanism. So provided Get With Signal is NOT used time-outs can occur. " I think this explains what you are seeing as well. -Tom -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Tom Schneider / IBM Global Services - MQSeries ASC (513) 274-4034 [EMAIL PROTECTED] -=-=-=-==-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- "Sproull, George" <[EMAIL PROTECTED]> Sent by: MQSeries List <[EMAIL PROTECTED]> 06/22/2004 11:15 AM Please respond to MQSeries List To [EMAIL PROTECTED] cc Subject OS/390 GET WAIT Troubles Hi, We recently upgraded from WebSphere MQ 5.2 to 5.3.1 on an OS/390 2.10 system. We run a homegrown trigger monitor which does a GET WAIT on the batch initiation queue, it runs as a batch job...not a started task. The JWT on this system is set at 15 minutes. For some reason, it seems that under MQ 5.2 the batch job did NOT abend with a S522 (JWT Timeout), but when we implemented MQ 5.3.1 it started to timeout. Was there some architecture change between releases that would account for this? I assumed the GET WAIT caused the program to wait on an ECB, but I can't figure out why it would not time out under MQ 5.2........was there some sort of keepalive handshake going on under the covers?
