Rails + Oracle problems

I'm having a problem getting Rails to connect to my Oracle database. I have Ruby/Rails installed on a SunOS (sun0) and my Oracle database (mydb) is installed on another SunOS (sun1). sun1 has the Oracle instant client on it, and I can run a simple ruby script to execute queries just fine:

#!/usr/local/bin/ruby require 'oci8'

conn = OCI8.new('user', 'pass', '//sun0:3333/mydb') conn.exec('select count(*) from t_mytest') do |row|   puts row end

This runs with no problem. Now comes my Rails issues. I've setup a simple Rails project and in my database.yml file, I swear I've tried every configuration I can, but the 'rake migrate' command still won't work. Here's what my database.yml file looks like:

development:    adapter: oci    username: user    password: pass    database: //sun0:3333/mydb

development:    adapter: oci    username: user    password: pass    database: //sun0:3333/mydb

development:    adapter: oci    username: user    password: pass    database: //sun0:3333/mydb

I've seen some folks saying the 'database' line in database.yml isn't read, and I've tried it also with the host line in there. But alas, it still doesn't work. Any ideas?

I guess I should mention the error I am getting. When run with the above configuration, rake migrate produces:

rake aborted! ORA-12162: TNS:net service name is incorrectly specified

If i remove the database: line in database.yml and include this line:

host: sun0

then rake migrate produces:

rake aborted! ORA-12452: TNS:no listener
