Stand-Alone Prefix Update is run as a standard z/OS® job. It consists of a single
job step. To run Stand-Alone Prefix Update, you must supply an EXEC
statement that invokes program FABYMAIN, and DD statements that define
inputs and outputs.
Before you begin
Before running Stand-Alone Prefix Update, consider tuning
your environment to improve performance. See
Performance and tuning for integral information about
performance and tuning.
Procedure
- Specify the EXEC statement in the following form:
//HPPR EXEC PGM=FABYMAIN,REGION=nnn
// PARM='IMSPLEX=ccccc,DBRCGRP=ddd'
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 DFSURWF3 DD statement. The minimum region size requirement
is approximately 512 KB. Performance improves as the region size is
increased. The recommended value for the region size is 8 MB or higher. Optionally, you can specify the PARM= parameter. It
can include the following parameters:
- IMSPLEX=ccccc
- Specifies the IMSplex name to be used for a RECON. This parameter
is 1- to 5-characters.
- DBRCGRP=ddd
- Specifies the 1- to 3-character identifier (ID) assigned to a
group of DBRC instances that access the same RECON data set in an
IMSplex.
- Provide DD statements.
