UNIX commands

Take Action commands that are issued on the Tivoli® Enterprise Portal with any of the following prefixes are issued as UNIX commands. By default, only user IDs that are defined for z/OS® UNIX System Services (USS) and have superuser, or root, authority are allowed to issue UNIX commands through the Tivoli Enterprise Portal.

Prefixes are as follows:

  • OMVS:, Omvs:, or omvs:
  • UNIX:, Unix:, or unix:

Use RACF® commands to define user IDs for z/OS UNIX . The z/OS UNIX attributes are maintained in the OMVS segment of the RACF user profile.

Follow these guidelines to enable users with Tivoli Enterprise Portal user IDs to issue UNIX commands:

  • The Tivoli Enterprise Portal user ID must be defined in RACF.
  • The profile that is associated with the RACF user ID must contain an OMVS segment.
  • In the OMVS segment, the z/OS UNIX user identifier (UID) must have a value of 0 (superuser).
