General

All application programmers in a z/OS environment have to check the following items:

  • User options file (CEEUOPT)

    A Language Environment user options object is supplied as part of the installation. When compiling a TIBCO EMS Client for z/OS (MVS) application, you must include the object during the link-edited step. The installation-supplied procedures already cater for this.

    Including the supplied user options object ensures that POSIX(ON) is set at run time and memory allocations are optimized.

    You can always include the TIBCO supplied object xxxUOMSG with your programs. The xxxUOMSG object is optimized for running EMS messages in batch mode.

  • Execution

    The TIBCO EMS Client for z/OS (MVS) API uses the TCP/IP socket interface. Most installations require a SYSTCPD DD statement in the execution JCL. For more information, contact your organization’s TCP/IP support personnel.
