Hi elainelaw

open /etc/bashrc file and add

Code:

$export ORA=/opt/ora
$export JAVAHOME=/usr/java

execute

Code:

source /etc/bashrc

Source the file rather than run it. When you run it it does work -- for the process the script is running in and any of its children; when that process ends the changes are lost; you want to make the change in your current shell; when you source the script its commands are run in your current shell exactly as if you typed them.
