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,
