upgrading from rails 1.1.6 to 2.3.2; problems with activerecord-oracle-adapter

I'm upgrading from rails 1.1.6 to 2.3.2 and having problems with
activerecord-oracle-adapter.
Following are the ruby, rails & gems versions. "ruby script/about" has
the problems.

I really suggest you upgrade from 1.1.6 to 1.2.6 first. Rails 1.2.6 has many
checks for deprecated (soon to be dropped) features. When your app runs
without warnings on 1.2.6, then move to 2.x. I'd also suggest a quick stop at
the latest version of 2.0.x or 2.1.x before jumping to 2.3.2. Much has
changed and trying to untangle it all at once will shorten you life, your
marriage (relationship), and hair coverage regardless of gender.

Don’t forget rake rails:update to update scripts, config etc.

Hi Jeffrey & Colin,

Thanks for your quick response. Just to give you a brief back ground:
Currently we have the application on a "production" box where we make
the client requested changes in the evenings or week-ends. We have
recently got a development box where I installed ruby 1.8.6; rubygems
1.3.3; rails 2.3.2 & ruby-oci8-2.0.1. The application itself is not
very large, so the changes and testing for rails 2.3.2 should not be a
problem.
Regarding the actual problem, I did do "rake rails:update" which was
suggested when I first ran "ruby script/about". After that, when I ran
"ruby script/about" again, I got the oracle adaptor error message. Is
it a gem installation, configuration or an application problem?

Rails 2.3 does not work with ruby-oci8 2.0.0.
gem install ruby-oci8 -v 1.0.4

Thanks Joyce. I am a step ahead when I went to ruby-oci8 1.0.4

Now I am struggling with the following:
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in
`gem_original_require': no such file to load -- environments/
