MQCONN resources

An MQCONN resource defines the attributes of the connection between CICS® and IBM® MQ. You can install or discard an MQCONN resource only when CICS is not connected to IBM MQ.

Only one MQCONN resource can be installed at a time in a CICS region. When you define an MQCONN resource, CICS checks to ensure that there is only one MQCONN resource defined in the group or list. If more than one is found, even one with a different name, a warning message is issued. If you do install a second MQCONN resource, CICS implicitly discards the existing MQCONN resource before proceeding with the installation, unless you are reinstalling an MQCONN resource with the same name.

When you have installed the MQCONN resource, you can use the CEMT SET MQCONN or EXEC CICS SET MQCONN command, CICSPlex® SM, or the CICS Explorer® to start the connection between CICS and IBM MQ.

When you install an MQCONN resource that specifies a value in the INITQNAME attribute, CICS also dynamically creates and installs an MQMONITOR resource with the reserved name of DFHMQINI representing the default initiation queue.

For details about DFHMQINI, see MQMONITOR resources.
