Hello,

I’m having problems with my Rails deployment (version 2.1.0, using  
Passenger). I have a basic Rails application which worked fine on an  
Ubuntu server, but after migrating it to RedHat the application  
sporadically shuts down. Now I’m trying to get the app to use Ruby  
Enterprise Edition, but the latest error I get is the following:

uninitialized constant  
ActiveRecord::ConnectionAdapters::OracleEnhancedAdapter
