将消息放在群集队列中

Question

We are trying to place message on IBM message clustered queue. When we place the message on the queue the following error will be thrown:

MQJE001: Completion Code '2', Reason '2085'.

When we try to place a message on a local queue on one of our queue managers it's working fine. But on a clustered queue it does not work.

MQQueue queue = null;
MQMessage mqMessage = null;

MQEnvironment.hostname = settings.getServer();
MQEnvironment.channel = settings.getChannel();
MQEnvironment.port = settings.getPort();

MQQueueManager queueManager = new MQQueueManager(settings.getQueueManager());

int openOptions = CMQC.MQOO_INPUT_AS_Q_DEF | CMQC.MQOO_OUTPUT;

queue = queueManager.accessQueue(settings.getQueue(), openOptions);

Can someone help us with placing message on a clustered queue?

Answer 1

MQRC 2085 is MQRC_UNKNOWN_OBJECT_NAME which normally means the queue manager you are connected to can't find this queue either locally defined or via the cluster(s) it is a member of.

Another reason you get a 2085 is if you try to open a clustered queue for INPUT ( GET ). You can only OUTPUT ( PUT ) to a clustered queue that is not located on the local queue manager. If you remove CMQC.MQOO_INPUT_AS_Q_DEF from your openOptions it should fix your problem. Unrelated to your problem, it is good practice to always include CMQC.MQOO_FAIL_IF_QUIESCING this will allow the queue manager to shutdown normally and not be held up by your process being connected.

int openOptions = CMQC.MQOO_FAIL_IF_QUIESCING | CMQC.MQOO_OUTPUT;

You can confirm if the queue manager you are connected too knows about this queue in its partial repository along with which cluster it is a member of and what cluster queue managers it is hosted on with the following command:

DIS QC(clustered_queue_name_here) CLUSTER CLUSQMGR

A partial repository only learns about a clustered queue the first time it is accessed so it may not show up until you fix your openOptions and try to access it again.
