Hello,
I'm playing with MQ clusters with 2 qmgrs.
I created CLUSRCVR on both qmgrs. And then created a CLUSSDR on 1st qmgr. And I noticed a auto-defined CLUSSDR on the 2nd qmgr too. I know this is how MQ clusters work, but what happens to this auto defined CLUSSDR if i define another CLUSSDR manually.
I did try it and noticed only 1 CLUSDR after manually defining it.
My question is, how to tell the diff b/w a manually defined CLUSSDR and auto-defined CLUSSDR?
How do I know if the displayed CLUSSDR is auto-defined instance or the one that I manually defined?
Thanks |

Read THIS for a very detailed explanation of how to determine the difference...

Hi - still [url=http://www.mqseries.net/phpBB2/viewtopic.php?t=75315&highlight=[/url] working through the MQ docs I see.

If it's to the other FR in the cluster, it probably disappears.

Told you.

Each queue manager in a cluster should have a manually defined CLUSSDR. I think you're asking how you tell if the channel has been automatically defined, and those channels have a different type that you won't see in a cluster with only 2 queue managers (which must of course both be FRs.

From the type that's being displayed.

Thanks for your replies.
While verifying the cluster objects, i noticed that all the channels(from dis chs(*) conname where(cluster eq cluster1) ) have the ip address in CONNAME field. but I defined all the manual channels with FQDN. (CONNAME('FQDN(PORT)')).
Question is, does the cluster automatically update this ip addresses on the auto-defined chls when any of the qmgr's IP address changes(but the hostname remains same). |

This is the usual behavior of channels (cluster and non-cluster) at channel attach time - if you don't specify an ipaddress in the CONNAME field, MQ software will attempt to resolve the name you do specify.
