Conn list w/o Multi-instance

[Jackson, Richard R.]

Group

We've gotten a few requests from outside partners to have multiple IP addresses on sender channel
even though the partner doesn't have a multi instance QMgr set up.

I think the intent is to have multiple routes to the same qmgr in case of a line failure.
These requests are probably coming from the network groups not MQ sysadmins.

I'm not familiar with NATing and IP broadcasting, etc... I'm guessing this is a view to hands off recovery.

Are there messages in the CHINIT that show an IP switch or is a Dis CHstatus required.
Any thoughts on this. Did anyone test this.

We do that quite a bit. I don't remember any messages coming out, as the
failover is fairly quick. However, channel startup can take a little bit
longer.

Thank you,

I guess my question is - does it matter to you if the ip switch occurs?

If the switch occurs, and the channel is still running successfully, then
there's basically no impact to you.

If the switch occurs, and the channel doesn't run successfully, then it's
the same as if the channel just failed without switching.

So as long as you're already monitoring the channel for stopped states,
then it shouldn't matter what IP address it's running on. At least, in my
view.

Thank you,

Jeff Lowrey

Using jboss 7.2 and WMQ 7.5.

12:17:16,884 WARN [org.springframework.jms.listener.DefaultMessageListenerContainer] (jmsContainerEmailUF-1) Could not refresh JMS Connection for destination '***@3b0d1fa0' - retrying in 5000 ms. Cause: MQJCA1026: An operation on a domain specific object was not valid.

Does anyone know how to resolve this error? I googled it but am afraid I am not understanding any of what was posted.
