User Master Records
The
user master records define the user accounts for enabling access to the
system. The user master records contain all the access information needed by
the system to validate a user logon and assign users access rights to the
system, such as passwords and authorization profiles.
User Buffer
User
buffers are special areas (tables) containing all the authorizations for the
user. These buffers are specific for individual users, and are actually built
when the users log on, based on the authorizations contained in the profiles
included in the user master record.
When
users try to perform activities in the system, the application programs and
transactions are checked against the authorization objects and values contained
within the user buffer.
The
number of entries in the user buffer can be controlled using the profile
parameter auth/number_in_userbuffer.
