Overview of Maintaining User Type Definitions
A user type defines a class of users, such as administrators, ordinary
users, operators, and so on. When enrolling a user through the Information Center Facility ENROLL
option, an administrator specifies a user type. Associated with each
user type is the following information the system needs to define
the user to the system and define the type of access the user has
to various parts of the system.
- USERID Information
- When you use Information Center Facility panels to define a user to TSO/E, you supply user ID information that automatically becomes the parameters for the TSO/E ACCOUNT command and/or RACF® commands, depending on how your installation is set up. If your installation uses the ACCOUNT command, the user ID information is stored in the user attributes data set (UADS) named SYS1.UADS. If your installation uses RACF commands, the user ID information is stored in the RACF data base. For more information about the ways to define users to TSO/E, see Defining Users to TSO/E.
- RACF Security Information
- RACF is an optional security server that protects system resources. You can supply information on Information Center Facility panels to define a user to an existing RACF group. A RACF group is a collection of RACF users who have the same access requirements to protected resources. A RACF administrator gives the appropriate access authority to each group.
- Master Catalog Information
- The master catalog keeps track of data sets in the system. You can use Information Center Facility panels to supply information for the VSAM DEFINE ALIAS command that puts a user catalog alias for the user's TSO/E ID into the master catalog. This action can improve performance by decreasing the time required to locate the user's data sets.
One of your jobs as an administrator is to maintain a set of user
type definitions. The Information Center Facility supplies
two pre-defined user types: USER and ADMINISTRATOR. If they are
not suitable for all users at your installation, you can add new user
types. You can also modify current user type definitions and delete
those that are no longer needed. To aid in choosing and maintaining
user types, you can display either a list of the currently defined
user types, which includes a brief description of each, or a particular
user type definition (that is, the information it specifies). For
descriptions of the information each user type can include, see:
