Hi,
I need help in cluster environment. We have 10 queue managers in DSOI cluster. QM1 and QM2 are full repository queue managers. Recently we have closed and removed both QM1 and QM2 queue managers from the cluster and made QM3,QM4 as full repository queue managers. We have deleted all the CLUSSDR channels to QM1 and QM2. Issue here is
1. Still i can see the CLUSSDR channels to QM1 and QM2
DIS CHS(*)
3 : DIS CHS(*)
AMQ8417: Display Channel Status details.
CHANNEL(CC_TO_QM1) XMITQ(SYSTEM.CLUSTER.TRANSMIT.QUEUE)
CONNAME(QM1(1414)) CURRENT
CHLTYPE(CLUSSDR) STATUS(RETRYING)
RQMNAME() AMQ8417: Display Channel Status details.
CHANNEL(CC_TO_QM3) XMITQ(SYSTEM.CLUSTER.TRANSMIT.QUEUE)
CONNAME(QM3(1414)) CURRENT
CHLTYPE(CLUSSDR) STATUS(RUNNING)
RQMNAME(QM3)
2. QM1 and QM2 queue managers are still showing in cluster.
DIS CLUSQMGR(*)
2 : DIS CLUSQMGR(*)
AMQ8441: Display Cluster Queue Manager details.
CLUSQMGR(QM1) CLUSTER(DSOI)
CHANNEL(CC_TO_QM1)
AMQ8441: Display Cluster Queue Manager details.
CLUSQMGR(QM2) CLUSTER(DSOI)
CHANNEL(CC_TO_QM2)
AMQ8441: Display Cluster Queue Manager details.
CLUSQMGR(QM3) CLUSTER(DSOI)
CHANNEL(CC_TO_QM3)
AMQ8441: Display Cluster Queue Manager details.
CLUSQMGR(QM4) CLUSTER(DSOI)
CHANNEL(CC_TO_QM4)
AMQ8441: Display Cluster Queue Manager details.
CLUSQMGR(QM5) CLUSTER(DSOI)
CHANNEL(CC_TO_QM5)
AMQ8441: Display Cluster Queue Manager details.
CLUSQMGR(QM6) CLUSTER(DSOI)
CHANNEL(CC_TO_QM6)
AMQ8441: Display Cluster Queue Manager details.
CLUSQMGR(QM7) CLUSTER(DSOI)
CHANNEL(CC_TO_QM6)
3. SYSTEM.CLUSTER.TRANSMIT.QUEUE is pilling up with cluster messages in QM5,QM6,QM7 queue managers. All the messages are pointing to QM1 and QM2 queue managers. Since the sender channels are deleted, messages are pilling up. Why messages are still coming up for the queue managers which are not in the cluster?
Can anyone please help me in resolving the above issues?
Note: I think the QM1 and QM2 queue managers are not properly removed from the cluster and we have shutdown the server holding both the queue managers.
Thanks,
Vaishnavi |

Yes, that's correct.
They were not properly removed from the cluster.
You need to forceremove them.

Thanks For the Reply.
How can i force remove them from the cluster?
Cluster is in production environment. Will this effect the Production data?
How can i do it without effecting the other cluster queue managers and their objects? Please send me the steps.
Thanks in Advance,
Vaishnavi |

Look up the RESET CLUSTER command in the MQ Clusters manual. You should probably read the entire MQ Clusters manual. Its not that big and the knowledge gained will (should) prevent your cluster problems.

Your cluster is broken.
All of your other cluster qmgrs are already affected.
You have already failed to handle your production environment in a proper manner. You should have run this same change - removing the old FRs and putting in the new ones, in a different environment FIRST.
The RESET CLUSTER will remove the cluster qmgr definitions for the old qmgrs.
It may not redirect messages on the XMITQ.

| Since the messages are not real data, I can clear off the messages on SYSTEM.CLUSTER.TRANSMIT.QUEUE. I want to know whether Resetting the cluster will solve my issues. Please suggest how to proceed. |

On top of this some of your cluster sender channels are now incorrect.
The manually defined cluster sender from any partial repository MUST go to a full repository or your cluster will not work...
