Input for IRRMIN00

IRRMIN00 expects one of the following parameters on the JCL EXEC statement:

PARM=NEW, specified when formatting a new RACF® database
PARM=UPDATE, specified when updating the templates on an existing database. IRRMIN00 adds or updates the templates as required and writes the segment table, while leaving the old profiles intact. PARM=UPDATE is the default if no parameter is specified.
PARM=ACTIVATE, specified when activating a new version of the templates.

IRRMIN00 requires the following DD statements:

ddname

Description

SYSPRINT

Defines the output data set. The minimum block size is 129 (enforced by a DCB exit).

SYSRACF

Defines a contiguous, unmovable, non-VSAM data set to be formatted.

The logical-record size and block size are required to be 4096. For PARM=NEW, this is forced by RACF utility processing. If you are updating an existing RACF data set, IRRMIN00 updates the RACF data set in place. Specify the real name of the data set; do not specify an alias.

Do not allocate this data set in the extended addressing area of DASD volumes. To ensure that this data set is not allocated in the extended addressing area, the SYSRACF DD statement must not contain the keyword parameter EATTR (unless its value is the default NO). Since EATTR=NO is the default, it is not necessary to include this on the DD statement.

Note: Before z/OS® Version 1 Release 5, IRRMIN00 required a SYSTEMP DD statement. If you have a SYSTEMP DD statement in existing IRRMIN00 JCL, and you do not remove it, it will be ignored.

For an example of the JCL required to allocate space, catalog the data set, and run the IRRMIN00 program, see Creating a RACF database.
