Dear Experts,
I tried to undeploy a message flow from an Execution Group, but timeout error occurs. Pl check the log.
P/F: AIX 5.3, IBM MB 6.1.0.4
Configuration QM is up and running fine.
$ mqsideploy -i localhost -p <portno> -q CONFQM -b MYBK -e MYEG.EG -d MY_MF
BIP1044I: Connecting to the Configuration Manager's queue manager...
BIP1045I: Connecting to the Configuration Manager...
BIP1062I: Removing the following objects from execution group 'MYEG.EG': MY_MF.cmf
BIP1100E: Broker MYBK had not responded before the timeout occurred.
$ ps -ef | grep -i MYEG.EG
cudbinst 925834 2310320 0 Dec 20 - 154:28 DataFlowEngine MYBK 01555df9-2101-0000-0080-fb25898b4c5b MYEG.EG 0
How can I undeploy the message flow?
Are there any checks that need to be done to rectify this. |

| Further, no Application is making use of the message flow. |

What do the various logs have to say about this? Does the broker respond correctly to other requests to deploy / undeploy flows or is it just this one?
Does the flow appear in the ConfigMgr's view or is it a phantom?

Recently at a client, we discovered Tivoli monitoring product was interfering with MQSI commands, causing the MQSI commands to hang. Our resolution was to apply several APARs for Tivoli. Are you using any Tivoli product on your system?

It's significantly more likely that the EG has gotten stuck in a loop and is thus not responding to the broker or that the Broker is stuck and not responding to the ConfigMgr than that Tivoli has been playing muckymuck with things.
It might even just be that channels between Broker and ConfigMgr aren't working or configured correctly. |

We had not set debug mode while doing the activity.

Broker responds correctly to other requests for all deploy/undeploy activities for other flows which runs on different EG's.

No.

Broker and Configmgr Qmgrs are configured properly and I don't see any abnormal things happening around qmgrs. |

I never said you had. The components still produce logs.
What about my other question?

Does the flow you're trying to undeploy still appear in the ConfigMgr's view of the topology under the broker?

Based on the fact that other execution groups still respond to deployment requests, this is the most likely explanation.
Check the message flows on the failing execution group for infinite loops or potential hangs. Or try deploying that execution group's message flows one at a time to a new execution group, to see if which one(s), if any, are causing your problem. |

Yes, MessageFlow is still appearing in the ConfigMgr's view of the topology.

Yes, checked MF thoroughly... No infinite loops.

Tried deploy the MF in new EG. Same problem exists. |

Do you have any adapter nodes in your message flow?
How big is the Bar file that you are using for deployment?
What does the Event Viewer/ User log say during deployment?
Have you tried to increase the timeout period to a bigger value?
| Code: |
| '-w timeoutValue' value in seconds to wait for the broker to reply to the deploy request |

New update is that, Message flow was trying to retrieve information from 2 tables which were some how got deadlocked. 
May be that's the reason why, message flow was unable to deploy.. and the broker time out occurred.
Any thoughts on this pls. |

If the flow is in use, either waiting for a database activity which will never finish or in in an infinite loop, then you can neither undeploy or redeploy the flow as commented above.
