User Guide

SAP AG November 2002
The following user data is needed to log on:
userid
User name
password
The user’s password
database_name
The name of the SAP DB instance you want to work on
server_node
The name of the server node on which the database you called is running
In addition to this generally required user data, you can enter further data, which is then
transferred when you log on.
You can also transfer the following user data to the SAP DB tools or the C/C++ Precompiler
programs:
• Enter user data as options [Page
31] (note that the required options [Page 34] must
always be entered for each tool used)
• Enter user data on the logon screen (for the Database Manager GUI and SQL Studio
tools)
Note the special features of entering user data in the SQL Studio (Opening a Database
Session [See SAP DB Library]).
• User Data Using XUSER [Page
34]
Entering incomplete or incorrect user data when calling the C/C++ Precompiler programs,
application programs, or the SAP DB tools cause the program to terminate with an error
message.
When you call the C/C++ Precompiler and application programs that were
generated using the SAP DB programming interface, you can also transfer user
data directly in the program itself. For this reason, the program contains a special
modified rule for the transfer of user data. Basically, the logon options for the
C/C++ Precompiler and application programs are the same as for the SAP DB
tools.
SAP DB User Classes
The SAP DB database system differentiates between two main user classes:
• Database Manager Operator (DBM Operator) [Page
134]
• Database Users [Page
136]
Database Manager Operator (DBM Operator)
Users working with the database management tool Database Manager [Page 133] are known
as Database Manager Operators. The SAP DB user class [Page 149] is the DBM operator.
Depending on what authorizations [Page
27] the DBM operator has been given, a DBM
operator is able to perform all kinds of Database Manager functions.
You create the first DBM operator when you install a database instance [Page
132]. When
you register a database instance, you must specify the name and the password of the first
DBM operator. In this way, you legitimize yourself as the DBM operator of the database
instance. The DBM operator’s password can be changed at a later date.
