Before you begin: You need to know which RACF® group profiles will be used as z/OS UNIX groups.
Perform the following steps to define RACF groups that can be used as z/OS UNIX groups.
- Log on to the user ID with RACF SPECIAL
authority.
_______________________________________________________________
- Issue one of the following commands. Base your choice on your
particular situation.
This
table shows the tasks for creating z/OS® UNIX groups.If you want to . . . |
Then issue. . . |
---|
Define a new RACF group profile and have it be used as a z/OS UNIX group |
The ADDGROUP command.
Example: To
define a RACF group profile
named SYS1 and to give it a GID of 575, issue: ADDGROUP OMVSGRP SUPGROUP(SYS1)
OWNER(SYS1) OMVS(GID(575))
Result: You
have defined a RACF group profile
and created a z/OS UNIX group.
|
Change a current RACF group
profile and have it used as a z/OS UNIX group |
The ALTGROUP command.
Example:
To add a GID of 678 to the current RACF group
ENGNGP7, issue: ALTGROUP ENGNGP7 OMVS(GID(678))
Result: You
have created a z/OS UNIX group.Use
AUTOGID to automatically assign an unused GID. For example: ALTGROUP ENGNGP7 OMVS(AUTOGID)
To
assign OMVS GIDs to all groups, use the ISPF shell.
|
Tip: For useful reports and auditing, assign a unique
GID to each RACF group name.
Reports for the RACF group
name will then supply information about the corresponding GID.
_______________________________________________________________
When you are done, you have created a z/OS UNIX group.
When the user connects to the system (for example, logs on to a TSO/E
session), one group is selected as the user's current group. When
a user becomes a z/OS UNIX user,
the GID of the user's current group becomes the effective GID of the
user's process. The user can access resources available to members
of the user's effective GID.
