Issue
Where do the environment variables under Jenkins ( manage jenkins -> system information ) come from?
I checked /etc/init.d/tomcat5, /usr/bin/dtomcat5, /usr/bin/tomcat5, /etc/sysconfig/tomcat5 and /etc/profile but do not see any such variables there specially the ones related to Oracle (Base, Home, Ld_lib, path, etc.).
Tomcat's bashrc has some oracle related variables which I commented out but I still see the same in the jenkins system info page. Any directions?
Solution
The environment variables displayed in Jenkins (Manage Jenkins -> System information) are inherited from the system (i.e. inherited environment variables)
If you run env command in a shell you should see the same environment variables as Jenkins shows.
These variables are either set by the shell/system or by you in ~/.bashrc, ~/.bash_profile.
There are also environment variables set by Jenkins when a job executes, but these are not displayed in the System Information.
