I am attempting to upgrade the em using the emca -upgrade <old_oracle_home> command

I keep getting the Database connection though Listener failed error message.

Some possible reasons may be:

1. Listener port XXXX provided is incorrect.    - The port provided is correct.

2. Listener is not up.   - Listener is up and accessible via remote client tools.

3. Database Service is not registered with the listener.  - lsnrctl status displays the correct service name.

4. Listener is up on physical host.... - It resides on a virtual host server.

5. Listener is up on virtual host. Set environment variable ORACLE_HOSTNAME=<virtual_host>    -- ORACLE_HOSTNAME=full host name (same host name in listener.ora)

Howdy, Stranger!
