Just today I completely wiped my hard drive and installed snow leopard  
fresh. I’ve installed several libraries with success so far, but can’t  
seem to get oracle working with rails.

I’ve installed the instant client successfully and am able to connect to  
the db using irb:

$ irb

> > require ‘oci8’  
> > =\> true
> 
> > OCI8.new(‘user\_name’, ‘password’, ‘//server/xe’).exec(‘select column\_1 from table\_name’){|r| puts r.first}  
> > “value1”

but I can’t get it to work with a Rails 1.2.5 project:

$ script/console  
Loading development environment.  
/Library/Ruby/Gems/1.8/gems/activerecord-1.15.5/lib/active\_record/connection\_adapters/oracle\_adapter.rb:537:NameError:  
undefined method `define_a_column' for class`OCI8::Cursor’  
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/activesupport-1.4.4/lib/active\_support/core\_ext/module/aliasing.rb:28:in  
`alias_method':NameError: undefined method`process’ for class  
`ActionController::Base' /Users/kpeyton/projects/dfttracker/app/controllers/application.rb:8:NoMethodError: undefined method`hide\_action’ for ApplicationController:Class

This is a little snapshot of what gems I have installed right now.

\*\*\* LOCAL GEMS \*\*\*

rails (2.3.4, 2.2.2, 1.2.6, 1.2.5)  
rsim-activerecord-oracle\_enhanced-adapter (1.2.1)  
ruby-oci8 (2.0.4)

I’m not able to downgrade my ruby-oci8 install to 1.x because I need 2.x  
for a different project with rails 2.3.4. Can anyone help me with  
getting this oci8 to work here?

Thanks alot.
