Making DFSMShsm exit routines available


Related topic
Use the following procedure to make DFSMSHsm exit routines available.
  1. Use the following table to determine which BMC AMI Storage exit routines you want available to DFSMShsm.

    BMC AMI Storage exit routines

    BMC AMI Storage

    Description

    ARCINEXT

    Required for DFSMShsm log record collection and reporting

    ARCRPEXT

    Required to use the BMC AMI Storage HSMRQUE and HSMPRTY functions

    ARCMDEXT, ARCRDEXT, and ARCSAEXT

    Required to use the BMC AMI Storage HSMBACKP, HSMDELET, HSMMIGRT, and HSMRECAL functions

    Function HSMMCCNV begins working as soon as the HSM collector is started.

  2. Make the BMC AMI Storage exit routines and modules available to DFSMShsm by adding the BMC library to the DFSMShsm STEPLIB or to LNKLST.

    Important

    Ensure that old copies of the exits do not exist in libraries in the concatenation.

  3. Activate the BMC AMI Storage exit routines by issuing the following command from the console (or TSO) or including it in the ARCCMDxx member in SYS1.PARMLIB.

     SETSYS EXITON (ARCINEXT, ARCRPEXT, ...)

    Important

    The ARCINEXT exit is only invoked during startup of DFSMShsm.

  4. If these DFSMShsm exits are already being used by your site or a third-party vendor, perform one of the following actions to allow exists to coexist with the BMC AMI Storage exits:
    1. Use the information in the following table to rename your exits to names that will be recognized by the BMC AMI Storage exits.


      BMC AMI Storage exits

      Load module name

      ARCINEXT

      USRINEXT

      ARCMDEXT

      USRMDEXT

      ARCRDEXT

      USRRDEXT

      ARCRPEXT

      USRRPEXT

      ARCSAEXT

      USRSAEXT

      When a BMC AMI Storage exit calls a non-BMC AMI Storage exit, the PSW key, PSW state, and registers are exactly the same as they were at entry to the BMC AMI Storage exit (except for register 15, which contains the entry point address to the non-BMC AMI Storage exit). The exit is called in the addressing mode in which the exit was link edited.

    2. Rename the BMC AMI Storage exits and modify your exits to call them.

    Important

    The PSW key, PSW state, and registers must be exactly the same as they were at entry to the non-BMC AMI Storage exit (except for register 15, which should contain the entry point address of the BMC AMI Storage exit). The BMC AMI Storage exit must be called in 31-bit addressing mode.
