BROKER V6.1 fixpack 3 on Windows
I see the following "command" every few minutes in the SYSTEM.BROKER.EXECUTIONGROUP.QUEUE
| Code: |
| <Broker uuid="638b5942-2001-0000-0080-dc04cd90b1d2" label="BROKER3"><Start><ExecutionGroup uuid="d3103d61-2001-0000-0080-931c02b13e21" label="DEV"/></Start></Broker> |
All message flows in "DEV" executiongroup is running. The DEV uuid in the command above is the one assigned to the EG in the BROKERAAEG DB. But, then every few minutes I get error message in windows event viewer stating that in internal START message for DEV failed. Any ideas? How can I stop this message from appearing every few minutes?
To me it looks like the broker thinks this EG is not running, so it is trying to start it periodically.

hmm, looks like that executiongroup is truly broken... it shows "running" in the toolkit..but that is all.
When I do mqsilist BROKER -e DEV it timeout after 360 seconds while this command is working 100% for other EGs.
I tried to stop flows in EG...not working.
I tried to delete EG...not working.
Guess I'm back to fiddling with DB to try and get rid of this EG...sigh

You might want to practice by defusing live bombs before you try that!
"Fiddling" is always risky. Make sure you've exhausted all the other options for removing phantom execution groups discussed in here before you get creative.

Hi,
It looks like your flow in that particular EG has gone into an infininite loop or the flow holds some external resources which it could not get rid of(For e.g the flow is in the debug session).
I think you have to remove all the inputs to the flows in the EG, stop debug session and kill the DataFlowEngine of that particular EG. Due to the resilient nature of the DFE, it automatically restarts. After that you can perform all the operations since the flow has stopped running.
Thanks,
Venkatesh |

I could not confirm that flow was in loop...so in the end I decided to cut the blue wire....
1. I used MQSILIST BROKER to find the process IDs
2. Then, I removed that line from the BROKERAAEG DB while broker was running
3. I stopped broker and killed last message flow engine that did not want to stop from task manager.
4. I removed ALL MQ messages from ALL SYSTEM.BROKER.* queues
5. Restarted everything
6. Did full topology deploy from domain view.
Maybe I was lucky...but it worked.
