System user roles
The Adaptive Server installation and setup process defines various user roles.
Different user roles have different responsibilities and privileges. These user
roles clarify the way Adaptive Server is to be integrated into your system:
• Operating system administrator – the individual who maintains the
operating system. This individual has superuser or “root” privileges.
• System Administrator – the individual in charge of Adaptive Server
system administration, creating user accounts, assigning permissions on
databases, and creating new databases. At installation time, the System
Administrator’s login name is “sa”. The “sa” login is not a UNIX login.
The “sa” login is specific to Adaptive Server and is used to log in to
Adaptive Server using the
isql command.
• “sybase” login – the “sybase” login is a UNIX login that owns all the
Sybase installation directories and files, sets permissions on those
directories and files, and performs the installation and upgrading of
Adaptive Server. This login is preferred, but not required.
Environment variables
It is crucial to the operation of Sybase products that the system environment
variables be set correctly.
Environment variables are set in the user’s environment either interactively or
by including them in the user’s .login and .cshrc files (for C shell) or .profile
file (for Bourne shell). The installation instructions in this guide explain when
to set these variables.
Note As part of the installation, the installer setup these environment variables
in SYBASE.csh and SYBASE.sh files. You can source the file to set their
environment.
• DSLISTEN – defines the name Adaptive Server uses to listen for client
connections if no name is given during the Adaptive Server start-up. If
DSLISTEN is not set, and no name is given during the Adaptive Server
start-up, the Adaptive Server name defaults to SYBASE.
