Oracle_enhanced adapter 'uninitialized constant' error


#1

Hi,

Can any one help me? I’m using Ubuntu and trying to connect to an oracle
database using oracle_enhanced adapter connection, but keeps getting
following error:

/usr/lib/ruby/gems/1.8/gems/activesupport-2.1.0/lib/active_support/dependencies.

require ‘active_record’

ActiveRecord::Base.establish_connection(
:adapter => “oracle_enhanced”,
:database => “xyz”,
:username => “user1”,
:password => “password1”,
:host => “abc.def.jkl:1521”)

class Connect < ActiveRecord::Base
set_table_name “changelog”
end

current_db = Connect.find(:first, :order => ‘applied_dttm DESC’)

Any ideas from any genius?

Thanks!
