both release versions - having problems. I had no issues with oracle 11g XE on opensuse 11.4 but on 12.1, the installation finishes but when I start the DB, database processes start but not the listener- without the listener, I cannot connect.

I tried replacing localhost with 127.0.0.1 in the listener.ora and tnsnames.ora files. That led to listener starting but when I connect, it says that the service name/id ( XE in my case) does not exist and the listener crashes again.

Any one had better luck ?
