Use IBM MQ classes for JMS in a CICS Liberty JVM server

From IBM MQ Version 9.1.0, Java programs running in a CICS Liberty JVM server can use the IBM MQ classes for JMS to access IBM MQ.

We must be using a IBM MQ Version 9.1.0 version of the IBM MQresource adapter. We can obtain the resource adapter from Fix Central (see Installing the resource adapter in Liberty).

There are two flavors of Liberty Profile JVMs available in CICS Version 5.3 and later, the types of connection possible to IBM MQ are restricted as follows:

    CICS Liberty Standard

    • The IBM MQ resource adapter can connect to any in-service version of IBM MQ in CLIENT mode
    • The IBM MQ resource adapter can connect to any in-service version of IBM MQ for z/OS in BINDINGS mode when there is no CICS connection (active CICS MQCONN resource definition) to the same queue manager from the same CICS region.

    CICS Liberty Integrated

    • The IBM MQ resource adapter can connect to any in-service version of IBM MQ in CLIENT mode.
    • BINDINGS mode connection is not supported.

For details on setting up and configuring the system, see Use IBM MQ classes for JMS in a Liberty JVM server in the CICS documentation.
