MQSeries.net :: View topic - Aggregate Execution Group shutdown and restart

Richard Jeong

Hi. Everyone.

I have a problem with Aggregation MsgFlow.
When I had tested with little MsgData , Aggregate MsgFlow was well done.
But When case with much MsgData ( over 500 transaction per second ),
Aggregate Execution Group was shutdown and restarted

- Timout is 10 in Aggregate Control
- Aggregate Send to 8 spoke
- unknown timeout is 10 in AggregateReply
- one execution group

Merchine's environment is below.

- QMGR Env :
HUB : ITBOX1T (on hubf1), ITBOX2T (on hubf2)
QM CLUSTER : CLUSTB (w/ Full Repository : ITBOX1T, ITBOX2T)
MQ ver : MQ 5.03 CSD 04
MQSI : Ver 2.1 CSD 04

- HUB's OS : AIX 5.2
- HUB's DB : DB2 9.0

I don't know why Execution Group was shutdown and restart.
Is so many thread is working in this merchine?
so execution group is down?

Please help me...
Thanks a lot.
