Enabling SMF record collection

Use the following procedure to specify IBM System Management Facility (SMF) exits for collecting SMF records, and where to write SMF data. BMC AMI Ops Monitor for Java Environments can collect SMF records when exit IEFU84 is invoked for STC and JESx. 

To enable SMF record collection

  1. On the COMMAND line, type D SMF,O to list the exit specifications for your system.

    Warning

    Important

    • By default, all exits are invoked for a statement if no exits are defined for that statement.
    • If NOEXIT is specified, no exits are invoked.
  2. Search for the following statements:
    • SYS(EXITS(IEFU84))
    • SUBSYS(ssss,EXITS(IEFU84)), where ssss is STC, JES2, or JES3

  3. If you did not find these statements, specify IEFU84 in the SMF parmlib member (SMFPRMxx).
    Specify IEFU84 on the EXITS option of either the SYS or SUBSYS parameter.

    Warning

    Important

    • In SMFPRMxx, SYS defines global exit specifications. You can optionally use the SUBSYS parameter to override specific subsystems.
    • Exercise caution when defining exits. Ensure that you do not inadvertently remove any exits that are already defined.

  4. Grant authorized read access to BPX.SMF (the Facility class resource) for JZOS and IMS.

    Example

    permit BPX.SUPERUSER CLASS(FACILITY) ACCESS(READ) ID(<userID>)

  5. Specify the following Java Batch Toolkit for z/OS (JZOS) environment variables:

    Warning

    Important

    To set these variables as the default for JZOS, specify the values in /etc/profile.
