Allow_concurrency with oracle

I have a script that does a batch update via parsing rss feeds every
hour. Originally I was using ActiveRecord with MySQL, however, upon
switchign to oracle 10 with the OCI8 driver and oracle_adapter.rb
things don’t seem to work.

Does anyone know if this is even possible? It appears that when using
ActiveRecord::Base.allow_concurrency = true then connections are set
to non-blocking. I seem to get errors when the oracle_adapter is
trying to see what columns are defined within the defined method. Has
anyone seen this?

Thanks for any help,
Mark J.
