Sybase DC35823-01-1500-04 manual System user roles, Environment variables, Introduction

CHAPTER 1 Introduction

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.
