I currently have MQ channels that do not start automatically when a message hits the Transmission Queue after going into 'IDLE' status for being inactive for 9000 seconds. This is preventing message reposnses from working. What can be done to resolve this?
FYI - MQ sender and receiver channels are set up to work between System i and System p systems. Regarding System i, we have backups that take place bringing down and bringing back up the channels. With System p, no stops and starts take place, but the MQs should start automatically when a message hits the queue during the business day.
Any assistance here will be greatly appreciated. Thanks in advance. |

They should be triggered if you want them to start when a message arrives on the XMITQ.

On distributed, the first (lexical order) channel that reads the XMITQ will be the one that is started (in case you have mistakenly defined more than one channel to read the XMITQ).
On z/OS, you better put the channel name in the TRIGDATA and it wouldn't hurt to do that on distributed. |

Okay, I will ask my peer to trigger the channels to see if that works.
As for the TRIGDATA parm, we did change it recently to the correct channel.
Thanks for the link. Maybe I can check the details of the transmission queues to see if the channel is set since no prcess definition exists. |

You don't need a Process def to trigger channels. But you wil need an initiation queue, and a channel initiator monitoring that initq.

Hi, I have yet to to find out when the triggering is set, etc.
The INITQ is set to its default as in the link. Not sure what you mean by channel initiator. Do you mean the channel that has the XMITQ assigned? I was also thinking maybe the INPROC (1) and OPPROC(2) were also to deal with this issue, but most likely not. Am I right? |

The channel initiator is an IBM-supplied trigger monitor application designed to start channels. You can create a channel initiator with MQSC commands (the preferred method), or start runmqchi manually.
Your XMITQ definition identifies the channel name to be started, and the initiation queue where the trigger event message is to be put. The channel initiator you start monitors the initiation queue, and starts the channel.

Yes, I understand. The channel initiator is set up, so that's good. The XMITQ parms were changed to the correct channels last week, so I got that done.
It appears that the channels are now triggered since yesterday, but the channels did not activate automatically this morning when a message was put in the queue. Do you think the System i recycles may be disrupting the System p triggered channels? |
