OID installed fine, opmnctl shows all services fine. confirmed ldapbind command works fine.
However, none of the web browser interfaces show up. eg (<host>:7001 ,7001/em). This is on RHEL 6.2
checked 7001 port is listening. (Have similar set up on Oracle Linux everything works fine)
are you accessing EM remotely or local? if you are accessing remotely then make sure firewall is disabled on server machine and login to weblogic console and check if listen address parameter is set to 'localhost' if so, remove the value and save the changes.
