Setting Oracle environment variables in Linux/UNIX

Oracle Database Tips by Donald Burleson


Environment variables are set in the sign-on scripts, and the system-wide scripts are located in /usr/local/etc (for HP/UX):

  • /usr/local/etc/profile (sh, ksh, bash)
  • /usr/local/etc/cshrc (csh)
  • /usr/local/etc/login (use for csh programs)
For individual users, you can create session start-up scripts in your default home directory (as specified in /etc/passwd), by placing a file in that directory.  For example, if the /etc/password file shows this for the Oracle user, we would add a dot-file called .profile in /home/oracle.
root> cat /etc/passwd|grep oracle
Other dot-file depend on the shell specified in /etc/passwd:
  • .profile (sh, ksh, bash)
  • .cshrc (csh)
  • .login (use for csh programs)
