This is one of the common issue we face in
Websphere MQ clusters Environment.
(e.g)
1 : display chs(*) AMQ8417: Display Channel Status details. CHANNEL(TO.QM2) XMITQ(SYSTEM.CLUSTER.TRANSMIT.QUEUE) CONNAME(computer.ibm.com(1414)) CURRENT CHLTYPE(CLUSSDR) STATUS(RETRYING)
Cause of the issue:
Either the remote queue manager is not available or there is an
incorrect parameter in either the local manually defined cluster sender channel
definition or the remote cluster receiver definition.
Checks to be done:
a) First check whether the
problem is the availability of the remote queue manager. Are there any error
messages?
b) Is the queue manager
active?
c) Is the queue manager's
listener running?
d) Is the queue manager's
channel able to start?
If the remote queue manager is available there could be a problem
with a channel definition. Check the definition type of the cluster queue
manager for the channel in retry state. For example:
1 : dis clusqmgr(*) deftype where(channel eq TO.QM2) AMQ8441: Display Cluster Queue Manager details. CLUSQMGR(QM2) CHANNEL(TO.QM2) CLUSTER(DEMO)DEFTYPE(CLUSSDRA)
If the definition type is CLUSSDR the channel is using the local
manual cluster sender definition. Alter any incorrect parameters in the local
manual cluster sender definition and restart the channel.
If the definition type is either CLUSSDRA or CLUSSDRB the channel
is using an auto-defined cluster sender channel based on the definition of a
remote cluster receiver channel. Alter any incorrect parameters in the remote
cluster receiver definition. For example, the conname may be incorrect.
1 : alter chl(to.qm2) chltype(clusrcvr) conname('newhost(1414)') AMQ8016:WebSphere MQ channel changed.
Changes to the remote cluster receiver definition will be
propagated out to any cluster queue managers that are interested and the
corresponding auto-defined channels will be updated accordingly. You can check
that the updates have been propagated correctly by checking the changed
parameter. For example:
1 : dis clusqmgr(qm2) conname AMQ8441: Display Cluster Queue Manager details.CLUSQMGR(QM2) CHANNEL(TO.QM2) CLUSTER(CLUSDEMO) CONNAME(newhost(1414))
If the auto-defined definition is now correct, restart the
channel.
