MODLUSER—Identify an OMVS Model User

Valid on z/OS.

Use the MODLUSER control option to specify the ACID that contains a model for a default OMVS segment. If the UNIQUSER control option is ON, any signed-on session ACID that accesses OMVS services without an OMVS segment receives the segment from the designated MODLUSER ACID and receives an automatically generated UID.

If the session ACID has no DFLTGRP, the MODLUSER DFLTGRP is also copied. If the DFLTGRP GROUP assigned to the session ACID has not been assigned a GID, an automatic GID is assigned to the GROUP.

This control option has the following format:

MODLUSER(acid)
acid

Specifies the ACID that contains a model of the OMVS segment. The ACID can be given the fields UID, HOME, OMVSPGM, OECPUTM, PROCUSER, ASSIZE, THREADS, MMAPAREA, MEMLIMIT, SHMEMMAX, and DFLTGRP. DFLTGRP will be copied if the OMVS user does not already have a DFLTGRP assigned.

We recommend DFLTGRP, HOME, and OMVSPGM for the MODLUSER ACID (to guarantee a valid entry to OMVS service environment). OECPUTM, PROCUSER, ASSIZE, THREADS, MMAPAREA, MEMLIMIT, and SHMEMMAX provide override values for identically named variables in the z/OS PARMLIB member BPXPRMxx; copying these values to session ACIDs overrides changes to your system PARMLIB and might require additional maintenance.

Note: For HOME, you can specify a variable that is replaced by the current user ID value when MODLUSER information is added to a user’s ACID record. Specifying &ACID (or a mixed-case entry) translates to an uppercase user ID value; specifying &acid translates to a lowercase user ID value. For complete information about the HOME keyword, see the CA Top Secret Command Functions Guide.

Example: Identify an OMVS Model User

This example specifies that the ACID JDOE contains a model of the OMVS segment:

F TSS,MODLUSER(JDOE)
