Environment:
WMQ v7.0.1.7
RedHat Linux 5.7
3 QMGRs, one on each of 3 VMs.
2 QMGRs are full repos, one is partial. All in the same cluster.
The 2 full repos (QM1 and QM2) each host Q1 as a cluster queue with CLWLUSEQ(ANY).
Partial repos(QM3) hosts an alias to a remote q definition of Q1.
Cluster sender channel setup on QM3 points to QM1. QM1 and QM2 are available.
Message broker from an outside (the cluster) server puts messages to an Output queue that resolves to the alias on QM3. All messages end up on QM1.
Issue one: Would like messages to end up in both Q1 on both QM1 and QM2.
Issue two: When QM1 is brought down, messages only get as far as the cluster xmitq on QM3 and eventually end up in the DLQ. I am expecting messages to end up on QM2.
I have been over the cluster pdf and a couple Developworks papers on this setup and can't seem to get it to work predictably. All involved objects and channels are in the cluster and have running status.
I've tried combinations of CLWLUSEQ settings on the Q and QMGRs.
Would like any input on what else to try.
Thanks,

Phil,
Can you please post the definition of the QAlias on QM3?

Phil, it may seem an obvious question but have you set BIND(NOTFIXED) on both instances of Q1?

Does the app specify BIND(NOTFIXED)?

In this scenario neither this nor the Q1 default bindings matter.
Read back the OP's post.
There is a reason why I asked for the definition of the Alias Queue on QM3...

So you're hoping to see something like:
| Code: |
QR(Q1_ALIAS) +
RNAME(' ') +
RQMNAME(' ') +
XMITQ(' ') |
but suspect that some of the blank attributes might not be blank?

CLUSTER(cluster name), for example.

I wouldn't expect to see anything in that attribute if it's an alias in a gateway...care to elucidate?

I was going to look specifically for the defbind attribute on that definition... and of course some others...

Here are the defintions to the QREMOTE, QALIAS on the Gateway QMGR:
DEFINE QREMOTE (Q1) DEFBIND (NOTFIXED) RNAME (Q1) RQMNAME (QM1) REPLACE
DEFINE QALIAS (INPUT) TARGQ (Q1) REPLACE

RQMNAME should contain a space as per cluster manual...

So.. Simply leave out the value in the RQMNAME for the definition.
So this doc:
http://www.ibm.com/developerworks/websphere/library/techarticles/1108_gupta/1108_gupta.html?ca=drs-
is wrong for:
Remote Queue Definition of Cluster Queue
DEFINE QREMOTE (IBM.ESB.IN) RNAME (IBM.ESB.IN) RQMNAME (IBMESBQM1)
DEFINE QALIAS (INPUT) TARGQ (IBM.ESB.IN)
I know its not magic, so the QMGR for where to put the message on must be populated by the Gateway QMGR based on the clustering algorithm?
