1 – Install SMF Exit IEFU83

To install SMF exit IEFU83, perform the following:

  1. Create the CTSU83A exit module.

    Member ASMU83A in the Connector INSTALL library is a sample member to assemble and link Connector for ACF2 exit IEFU83. ACFU83A member in INSTALL library is the source code of the IEFU83 exit.

    Review the JCL carefully and submit the job to create the CTSU83A load module in the Connector LOAD library. All job steps must end with a condition code of 0, except for the following:

    • CHECRCF – Ends with the condition code 4.

    • RCFU83A – This step is not executed.

  2. You can either copy CTSU83A module to your LPALIB (this requires you to do an IPL) or you can use the dynamic exit facility feature of MVS. It is recommended that you use the dynamic exit facility. The following step assumes that you use the dynamic exit facility for the SMF exit. If, for any reason, you want to set the SMF exit in the LPA (and do an IPL) skip to step 3.

    1. Define the SMF exit in the MVS dynamic exits facility.

      Edit member PROGnn in SYS1.PARMLIB to define the new SMF exit module, for all SMF sub-systems.

      Add the following statements to the member:

      Copy 
      EXIT ADD EXITNAME(SYS.IEFU83) MODNAME(CTSU83A)DSNAME (<CTSA LOAD library>)
      EXIT ADD EXITNAME(SYSSTC.IEFU83) MODNAME(CTSU83A)
      DSNAME (<CTSA LOAD library>)
      EXIT ADD EXITNAME(SYSTSO.IEFU83) MODNAME(CTSU83A)
      DSNAME (<CTSA LOAD library>)

      If JES3 is active in your environment, please add the following line as well:

      Copy 
      EXIT ADD EXITNAME(SYSJES3.IEFU83) MODNAME(CTSU83A)

    2. Activate the exit by issuing the following operator command:

      SET PROG=nn

      where nn is the suffix of the PROGnn member which was updated in step 2 above.

      Note
      Installation of SMF exit IEFU83 is complete. Proceed to step 3 if you need to set the SMF exit in the LPA and do an IPL.

  3. To set the SMF exit in the LPA (and do an IPL):

    1. Copy CTSU83A to your LPA system library.

      Edit member CPYU83A in the Connector INSTALL library. The job copies load module CTSU83A to your system LPA library.

      Review the job carefully and submit the job. All job steps must end with a condition code of 0.

    2. Activate the exit in LPA.

      Once the exit module resides in your LPA library, activate the module. This is usually performed by the next IPL with the CLPA option.

      If you have a product which can dynamically load modules to the LPA (for example, RESOLVE, LOOK, OMEGAMON) you can use it to add the exit to the LPA. However, when loaded in this manner, the exit remains active only until the next IPL.

    Note
    Installation of SMF exit IEFU83 is complete.
