hello DBA forums

I have a new 11g installation on solaris 11 (openindiana) that seemed to go well. But when I go to log into the database I see this message:

Code:

My oracle home is set to:

And my oracle_sid is set to:

I did my entire oracle install on a zfs pool for enhanced performance.

Code:
-bash-4.0$ ls -l /tank/oracle/

I'm sure it's a matter of tweaking some environment variables but please help me learn what I need to do to log into my new database.

Curiously I can log into the web interface but not from the command line.

thank you!
