Running Stand-Alone Prefix Resolution

Stand-Alone Prefix Resolution is run as a standard z/OS® job. It consists of a single job step. To run Stand-Alone Prefix Resolution, you must supply an EXEC statement that invokes the program FABYMAIN, and DD statements that define inputs and outputs.

Before you begin

Before running Stand-Alone Prefix Resolution, consider tuning your environment to improve performance. See Performance and tuning for integral information about performance and tuning.

Procedure

  1. Specify the EXEC statement in the following form:
    //HPPR   EXEC   PGM=FABYMAIN,REGION=nnn

    where nnn is the region size. The minimum region size requirement depends on the internal sort/merge requests and on the number of I/O buffers specified on the DFSURWF1, DFSURWF3, and DFSURIDX DD statements. The minimum requirement is approximately 4 MB. Performance improves as the region size is increased. The recommended value for the region size is 8 MB or higher.

  2. Provide DD statements.

    For a list of DD statements for Stand-Alone Prefix Resolution, see DD statements for Stand-Alone Prefix Resolution.

  3. Provide control statements.

    For a list of control statements for Stand-Alone Prefix Resolution, see Control statements for Stand-Alone Prefix Resolution.

  4. Specify the following FABYIN control statement:
    UPDATE=NO

    This control statement is optional because UPDATE=NO is used when UPDATE control statement is not specified.
