Thursday: yes, I'll be there (though it's also OK with me if we need to reschedule to get more people).

ORACLE_SID just specifies the SID to connect to if you don't specify one when you're connecting. I've gone months at a time without even having ORACLE_SID defined, because I always specify my SID explicitly. sqlplus catherine goes to ORACLE_SID sqlplus catherine@db2 goes to the instance with SID DB2 For creating it, you'll probably want to use dbca (database creation assistant), which asks for the database's name as one of the first steps. -- - Catherine http://catherinedevlin.blogspot.com
