running wmqi 2.1 csd06, unix borker.
We are having an intermittent problem when deploying. the deploy timeout adn the execution group remains in doubt state. Not sure what causes this but is normally resolved by a restart of the broker. The problem comes when issuing the mqsistart broker command. multiple instance of the dataflow engine come up which cannot be 'killed', any further restarts sometimes results in the other dataflow engines coming up with multiple instances. We have been resolving this by restarting the server itself.
I have tried to track the deploy messages between the broker and config manager and the reason it sometimes times out is the time it takes the config to send a message to broker is too long.
I am not sure what causes this and how it can be resolved bearing in mind that it an intermittent problem. |

You can try to increase the time-out limit on the broker(s) with mqsichangebroker <BrokerName> , the syntax:
mqsichangebroker BrokerName [[ -i ServiceUserId ] -a ServicePassword ] [ -p DataSourcePassword ] [ -s UserN
meServerQueueManagerName ] [ -t | -n ] [ -l UserLilPath ] [ -g ConfigurationTim
out ] [ -k ConfigurationDelayTimeout ]
e.g. mqsichangebroker <BrokerName> -g 3600 -k 3600 |

I think one of your message flow might be looping. Default timeout value on the broker is good enough to do the deploy of large message flow. Are you trying to do the complete deploy of your EG or Broker?

Would looping message flow cause a deploy time out? i have been only tracking the resource utilisation when I suspect a looping message flow.
We have increased the timeout already and I agree that we may need to increase this if the broker needs to be deployed instead of the execution group.
Any reason why multiple instances of the dataflow engine come up after a mqsistop has been issued? How to avoid this? |

WMQI 2.1 CSD04 unix broker:
Now I am timing out because the deploy message is stuck on the SYSTEM.BROKER.EXECUTIONGROUP.QUEUE queue and the stop/start flow messages are stuck on the SYSTEM.BROKER.ADMIN.QUEUE queue.
The broker is not picking these messages up and I have no clue where to look for errors/problems.Not much in /var/adm/messages files. Restarting the broker sometimes helps. I need to know why this is happening. DB2 has no visible issues. |

Is there a reference where i can read on the sequence of events during a deploy.Specifically,I need to understand the role of the system queues and the communication with the broker and configuration.
Still timing out with 3212489byte message in SYSTEM.BROKER.EXECUTIONGROUP.QUEUE.
Is there a limit to the size of this message?
Configuration timeout is already at 900 secs.
Please help!!! |

I think one of the presentation from Conference talks about the role of each system queue and how messages flow thru them.
I think the limit would be imposed by your queue and channel max message length. How big is your message flow? Whatsthe max message length on your mq queue/channel?
