connecting to an oracle database on an hp server

Well I'm at my wits end...

I have an oracle database on an HPUX box that I can connect to using
this code:

require 'oci8'

connection = OCI8.new('user','passwd','connectstring')
connection.exec("select table_row from table") do |row|
puts 'column 1: ' + row[0] # outputs "dummy: X"
end

Works beautifully, but when I set up a rails application I get

OCIError in ArtifactController#new

ORA-12154: TNS:could not resolve the connect identifier specified

Here is my database.yml file
===================================================

# MySQL (default setup). Versions 4.1 and 5.0 are recommended.
#
# Install the MySQL driver:
# gem install mysql
# On MacOS X:
# gem install mysql -- --include=/usr/local/lib
# On Windows:
# There is no gem for Windows. Install mysql.so from RubyForApache.
# http://rubyforge.org/projects/rub...
#
# And be sure to use new-style password hashing:
# http://dev.mysql.com/doc/refman/5.0/en/old-c...
development:
adapter: oci
username: xxxxxxxxx
password: xxxxx
host: host_alias:port

# Warning: The database defined as 'test' will be erased and
# re-generated from your development database when you run 'rake'.
# Do not set this db to the same as development or production.
test:
adapter: oci
username: xxxxxxxxx
password: xxxxx
host: host_alias:port

production:
adapter: oci
username: xxxxxxxxx
password: xxxxx
host: host_alias:port

I can't think of anything to check and google doesn't tell me much
except for

http://ruby.about.com/od/enterprise/ss/ruby_or...

Which is where I started out 3 hrs ago.

Found this Rails wiki
(http://wiki.rubyonrails.org/rails/pages/HowtoConne...)
and notice the database.yml they show is a bit different than yours.
Lots of info there about getting conencted
