Configuring CICS to use the WebSphere MQ transport

If you want to use the WebSphere® MQ transport with Web services in CICS®, you must configure your CICS region accordingly.

You can find more detailed information in the MQ Series System Setup Guide.
  1. Include the following libraries in the STEPLIB concatenation.
    • thlqual.SCSQANLx
    • thlqual.SCSQAUTH
    where:
    • thlqual is the high level qualifier for the MQ libraries.
    • x is the language letter for national language.
  2. Include the following libraries in the DFHRPL concatenation.
    • thlqual.SCSQLOAD
    • thlqual.SCSQANLx
    • thlqual.SCSQCICS
    • thlqual.SCSQAUTH
    • thlqual is the high level qualifier for the MQ libraries.
    • x is the language letter for national language.
  3. Specify the following CICS system initialization parameters.

    INITPARM=(CSQCPARM='SN=queuemanager,TN=traceptid,IQ=initiation_queue')
    MQCONN=YES

    where:
    • queuemanager is the subsystem name.
    • traceptid is the trace number that identifies the adapter in CICS trace entries.
    • initiation_queue is the name of the default initiation queue.
  4. Ensure that the coded character set identifiers (CCSIDs) used by your queue manager and by CICS, and the UTF-8 and UTF-16 code pages are configured to z/OS® conversion services. The CICS code page is specified in the LOCALCCSID system initialization parameter.
