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.
Sybase 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.
