Hello,
In WMQ 7.0.1.3, I am getting messages in the DLQ of particular queue manager(Name : TMP.XXX.BRK.QMGR). When i browsed the DLQ messages using MA96 API, we noted its showing MQRC_Q_FULL for a system queue SYSTEM.CHANNEL.INITQ. It looks like this queue manager is trying to pass the mesasge to another queue manager(TMP.YYY.BRK.QMGR) via sender channel(TMP.XXX.YYY.CHL). I have pasted below the DLH and some parameters. Can someone have any clue on this ?

You altered the SYSTEM.CHANNEL.INITQ to have a MAXDEPTH(0)?
Or you mean that the CURRENT DEPTH of SYSTEM.CHANNEL.INITQ is 0?
If you altered a SYSTEM object, you have at a minimum pointed the gun at your own foot and pulled the trigger. Depending on what SYSTEM object it is, changes what body part the gun is pointed at. |

WHICH THING IS ZERO?
The PROPERTY of the queue named "MAXDEPTH"?
Or the NUMBER OF MESSAGES ON THE QUEUE? |

MAXDEPTH and CURDEPTH are different attributes. What are the values of each?

Hi Jedi,
Maxdepth is 1000. curdepth is 0. I mean to say, when i am getting messages in the DLQ, curdepth is still showing zero only. |

do you use xmitq triggering to start the channel? if so, please check that "FIRST" is used, and not "EVERY"

Hi Padawan
Thanks for the reply. Yes, i am using xmitq triggering to start the channel. As you said, trigtype is given as 'every', which i changed it to 'FIRST' just now. So this is my understanding. When more than 1000 messages pumped into transmission queue, its sending the trigger message to SYSTEM.CHANNEL.INITQ. Since its maxdepth is 1000 only, its throwing MQRC Full error. if we give, trigdata as FIRST , then it will send trigger message only once to start the channel. Kindly confirm if my understand is correct? |

No, its sending the trigger message as soon as trigger conditions are satisfied. It would only wait to 1000 if you were using trigger type depth and had it set to 1000. Or if you were using some other trigger type and all trigger conditions only were met at the same time the queue reached 1000 by sheer coincidence.

It will send a trigger message each time trigger conditions are met. And that's a good thing because it means your channels will be reselient and you won't be called to restart the channekl any time the network farts.
