Users (TIAM or UTM users) require a BS2000 system user ID in order to be able to work in BS2000.
TIAM users are identified in BS2000 by a symbolic processor name and the BS2000 user ID. UTM users are identified in the openUTM system by a symbolic processor name, the name of the UTM application and the KDCSIGN or LSES name.
In order to use SQL to work with a SESAM/SQL database, BS2000 users require an SQL user authorization identifier. The database must contain a system access for that authorization code. A system entry is a system user ID and authorization identifier combination. An SQL user is represented by all system accesses in the database system which contain his or her authorization code.
When a database is moved to a different computer, you must create a system entry for the database on the new computer before the database is moved. If this is not done, it is not possible to access the database after the move.
Figure 9: Example of system access by an SQL user
In section “Specifying an SQL user's authorization identifier” there is a description of how an SQL user identifies himself/herself to SESAM/SQL with an authorization code.
