2531 (09E3) (RC2531): MQRC_PUBSUB_INHIBITED

Explanation

MQSUB, MQOPEN, MQPUT, and MQPUT1 calls are currently inhibited for all publish/subscribe topics, either with the queue manager attribute PSMODE or because processing of publish/subscribe state at queue manager start-up has failed, or has not yet completed.

Completion code

MQCC_FAILED

Programmer response

If this queue manager does not intentionally inhibit publish/subscribe, investigate any error messages that describe the failure at queue manager start-up, or wait until start-up processing completes. If the queue manager is a member of cluster, then start-up is not complete until the channel initiator has also started.

On z/OS, if you get this return code from the Chinit for the SYSTEM.BROKER.DEFAULT.STREAM queue or topic, then the Chinit is busy processing work, and the pubsub task starts later. Use the DISPLAY PUBSUB command to check the status of the publish/subscribe engine to ensure that it is ready for use. Additionally, on z/OS, you might receive an information message CSQM076I.
