I am having problems removing a queuemanager from the cluster.
I have 2 FR and 2 PR (all in Unix). The 2 PR have to be removed from the cluster (these systems are going to be restaged)
On the PR1 I altered the clusterrcvr channel, making the cluster attribute empty. Then I did a refresh cluster on the FR. When I checked with dis clusqmgr it was indeed out of the cluster.
Now when I tried this with PR2, it didn't work. I did the exact same thing, but for some reason on FR1 it is indeed out of the cluster, but when I look at FR2 it isn't. The channels between the 2 FR are working.
I resorted to doing a 'reset cluster... qmid... action(forceremove)' but that didn't remove it.
Can anyone help me?
P.S. I already tried bringing it back into the cluster and trying it again, it didn't work |

Why?

Again, why?
Follow the Clustering manual, it will save you so much heartache. _________________ It's puzzling, I don't think I've ever seen anything quite like this before...and it's hard to soar like an eagle when you're surrounded by turkeys. |

Why a refresh? Why not the rest of the steps to remove a queue manager from a cluster?

No it wasn't .

No, what you've got is an inconsistent and broken cluster.

No, it wouldn't

Rebuild a new cluster with a new name and use that.

How about following the Clustering manual? How about following Vitor's suggestion? How about considering that doing things "to see what happens" is one of the biggest causes of broken clusters?
There is a set of tried, tested, and trusted procedures for administering clusters, and the best advice and practice is to use them. _________________ It's puzzling, I don't think I've ever seen anything quite like this before...and it's hard to soar like an eagle when you're surrounded by turkeys. |

hi, exerk, yes, we should have followed the manual, planned it thoroughly in advance. I suggested the above because the cluster seemed already in an inconsistent state, I guess one would want to make some desperate moves at this point, wishing that would work even though chances were slim.
I am not advocating changing without planning. It's not right in any case. |

If you're in a plane that's crashing, would you run to the front and grab the controls from the pilot, believing that it's best to make a desparate move and wish it would work? I have to admire the optimism, though I question the reasoning!
I think I see what you're getting at, but can't agree with it. Even if you're in desparate straits (and IMHO the original poster's certainly there) thrashing round wildly in the hope of fixing stuff is not going to help. Experience teaches that a bad situation can always get worse.
Or maybe that's just my experience.
There's also the management belief that, in a crisis, doing something is better than doing nothing and thinking counts as doing nothing. This is a trout-inducing school of thought.

This is I think the key lesson from this post. _________________ Honesty is the best policy.

And a bunch of problem scenarios in the back of the manual with detailed solutions for each. 99.9% of the time you can find one that matches your dilemma. _________________ Peter Potkay
