title: Environment variables in Jenkins
body: <p>Where do the environment variables under Jenkins ( <em>manage jenkins -&gt; system information</em> ) come from?</p>
  <p>I checked <code>/etc/init.d/tomcat5</code>, <code>/usr/bin/dtomcat5</code>, <code>/usr/bin/tomcat5</code>, <code>/etc/sysconfig/tomcat5</code> and <code>/etc/profile</code> but do not see any such variables there specially the ones related to Oracle (<code>Base</code>, <code>Home</code>, <code>Ld_lib</code>, <code>path</code>, etc.).
  Tomcat's <code>bashrc</code> has some oracle related variables which I commented out but I still see the same in the jenkins system info page. Any directions?</p>
