CHAPTER 3
Configuring the Operating
System
This chapter discusses the operating system configuration settings that
you can adjust after installing or upgrading Adaptive Server. Unless stated
otherwise, the information pertains to all supported UNIX platforms.
Setting environment variables
Note As part of the installation, the installer creates SYBASE.sh and
SYBASE.csh files in $SYBASE directory for user to source to setup all the
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).
Only the file owner or the “root” user can edit a user’s .login, .cshrc, or
.profile file.
