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.

class Connect < ActiveRecord::Base
  set_table_name "changelog"
end

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



Any ideas from any genius?

Thanks!
