first...I am fairly new to MQ....
I have a sender channel that does not start when a message is put in the queue. I am putting the message in my local queue and then sending it to another queue manager via a xmit queue. If I don't put a message in there for a while it times out and the sender channel doesn't start again when a message is put in the queue. I am running MQ 6 for windows. Is there an attribute that I should be setting that I am not? The other queue manager on the solaris box always starts its sender channel properly. I just have this problem on the windows side sender channel.
any help is great....thanks |

| You need to read up about triggering the channels. Do a search here, in fact I think there is a FAQ on here too. |

Kevin is right but here's the down and dirty...
On your Transmit Queue make sure that the following is set:
INITQ(SYSTEM.CHANNEL.INITQ)
USAGE(XMITQ)
TRIGGER
TRIGTYPE(FIRST)
TRIGDEPTH(1)
TRIGDATA(SDR.CHANNEL.NAME)
If you don't want the Channel to stop, ever set DISCINT(0). Then the SDR Channel will only stop if the MQManager goes down or there is some other problem.

You do not need to set TRIGDATA, ever since 5.1. The channel initiator will look for the channel using the xmitq.

Since 5.1 or after 5.1?
In WMQ 5.1 and earlier versions didn't we have to define a PROCESS that pointed to the Channel?
Either way, it's always good to be able to see the channel name in the TRIGDATA field.

Interesting, but I agree, it's better, to enter the channel name in the TRIGDATA field. Otherwise you will get problems, when you define two channel using the same XmitQ (e. g. one, for SSL, and another one as backup, if SSL does not work).

However in 6.0 RP1 I have seen channels that refused to start until the TRIGDATA was set. I should specify that this was on regular sdr/rcvr channel in a clustered qmgr.

Can we use the same xmitq for 2 different channels? |

Yes, but you can only have one started at any point in time.
Cheers,

No, that was a bug in 6.0 GA. It was fixed in RP1.

Not according to my environment (AIX broker qmgr at 6.0 RP1 part of a cluster and std snd /rec channel to a qmgr outside of the cluster) Behavior was flaky until I added the Trigdata and then it behaved as expected.

I was thinking of APAR IY77282, and that is definitely in RP1.

Looking at dsmpqver
| Quote: |
Name: WebSphere MQ
Version: 6.0.1.0
CMVC level: p600-100-051021
BuildType: IKAP - (Production)
|
and I had to put the trigdata into the xmitq for the channel to trigger correctly...
Like I said the qmgr is in a cluster. This might have some influence.
