2342 (0926) (RC2342): MQRC_DB2_NOT_AVAILABLE
An MQOPEN, MQPUT1, or MQSET call, or a command, was issued to access a shared queue, but it failed because the queue manager is not connected to a Db2® subsystem. As a result, the queue manager is unable to access the object definition relating to the shared queue.
This reason code occurs only on z/OS®.
Configure the Db2 subsystem so that the queue manager can connect to it.
