Another Helpful Hint - Debugging why opmnctl won't start

Another day, another new box setup by someone else. Turns out they forgot to disable SELINUX when doing the OEL install. The result is that all of your installs work just fine. Except when you go to try to run opmnctl you get this lovely error: /u03/middleware/Oracle_IDM1/opmn/bin/opmn: error while loading shared libraries: /u03/middleware/Oracle_IDM1/lib/libdms2.so: cannot restore segment prot after reloc: Permission denied Can you ask the team if they know anything The solution is as root edit /etc/selinux/config And then set SELINUX=disabled then reboot.
