Syntax
Parameters
- PRIV={Off|On}
- Indicates which state privilege
support is set to. The values are:
- OFF
- Privilege support is turned off for all resource types. All resources are considered non-privileged.
- ON
- Privilege support is turned on for all resource types. Privilege space is set aside for each resource type.
- ON,SMALLENV=ON
- Privilege support is turned on for all resource types. Privilege space is set aside for each resource type, according to Small environment activation and reservation rules. See Privilege support and the emergency subsystem.
Authority Required
This command requires system authority. The description of the $T RDRnn command explains how to ensure that the authority of the appropriate MVS system command group is assigned.
This command also requires read security access authority. For a description of assigning command input authority, see z/OS JES2 Initialization and Tuning Guide.
Programming considerations
Privilege support can only be turned on by using $T LIMITS,PRIV=ON if the support is turned off by using $T LIMITS,PRIV=OFF.
Privilege support cannot be turned on by using $T LIMITS,PRIV=ON or off by using $T LIMITS,PRIV=OFF if privilege support is suspended because of an error.
Privilege support cannot be turned on by using $T LIMITS,PRIV=ON if all of the members of the MAS are not at release z/OS V2R3 or higher, or if the MAS is not at checkpoint level z22 or higher.
To activate privilege support using the Small environment activation and reservation rules, first turn off privilege support using $T LIMITS,PRIV=OFF. Then, turn on privilege support requesting Small environment by using $T LIMITS,PRIV=ON,SMALLENV=ON.
Scope
MAS-Wide. This command has an effect across the entire MAS.
