Note: Oracle Linux 6 (OL6) or Red Hat Linux 6 (RHEL6) has deprecated inittab, rather, init.ohasd will be configured via upstart in /etc/init/oracle-ohasd.conf, however, the process ""/etc/init.d/init.ohasd run" should still be up.
for example on one of our test boxes: [root@fwlxrac1 ~]# more /etc/init/oracle-ohasd.conf
