The database system differentiates between two main user classes:
· Database Manager operators (DBM operators)
When you create new database instances, you must first create the first user of each of these classes for each instance. These are the first Database Manager operator and the database system administrator (SYSDBA user).
Each of these users then has the authorization to create additional users of the specified main classes.
See also: User Concept in the Database Administration documentation.
Note that a Database Manager operator can manage a
database instance but cannot work with the database objects.
A database system administrator, on the other hand, can work with the database
objects and also has the authorizations of the first Database Manager
operator. This means that he or she can also perform all Database Manager
functions.
You can perform the following administration tasks with the Database Manager GUI:
