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 Johnson
