I have installed latest OEM 12c in OEL 5.7 64 bit. I am trying to discover target database from remote host (RHEL 4.5 32 bit). Installed agent and listener running on port 1585. When i am trying to discover target database, its detecting listener. But its not finding the database. I have registered the listener with the database (local_listener). Please let me know how to resolve this.
