After you have installed and configured Oracle Database XE Server, users must set their environment before they use Oracle Database XE. They do not need to log on with root permissions to do so. Oracle Database XE provides a script that sets the necessary environment variables.

Follow these steps:

    1 .

      Go to the following directory:

      /usr/lib/oracle/xe/app/oracle/product/ 10 . 2 . 0 /server/bin
    2 .

      Look for the following scripts:
          

            oracle_env.sh (for Bourne, Bash, or Korn shell)
    3 .

      Run the appropriate script for your shell. For example:
          *

            Bourne, Bash, or Korn shell:

            $ . ./oracle_env.sh




You may also want edit your login or profile files so that these environment variables are set properly each time you log in or open a new shell.

For Bourne, Bash, or Korn shell, enter the following line into the .bash_profile (to log in) or .bashrc file (to open a new shell):

. /usr/lib/oracle/xe/app/oracle/product/ 10 . 2 . 0 /server/bin/oracle_env.sh

. /usr/lib/oracle/xe/app/oracle/product/ 10 . 2 . 0 /server/bin/oracle_env.sh
