The universal access authority assigned to each resource defines the access that all users have to a resource unless the users are in the access list. The meaning of the universal access authorities varies depending on the type of resource that is being defined. For example, the following UACC values are valid for resources defined through the RACF® DATASET class:

NONE

Specifies that the user or group of users is not permitted to access the resource.

EXECUTE

Specifies a user can load and execute a program from a private program library but cannot read or copy the program.

READ

Specifies the user can read from the resource.

UPDATE

Specifies the user can read from or write to the resource.

ALTER

Specifies a user the maximum access RACF allows to the resource and permits a user to update a discrete profile.
