Where did "Please try again" come from? Is this your own exception 
handler? Try commenting that out so you get a full backtrace.

There's probably an AR method you can use to inspect the class 
(Irb.column_names maybe?) And in any case, check there are accessor 
methods for the columns you expect, e.g.

   x = Irb.new
   x.irb_number = 123
   x.pi_full_name = "bar"

If this is a rails app, use "script/console production" as an easy way 
to do this. It fires up a Ruby IRb shell with your models already 
loaded.

And finally, if you are developing for Oracle, then your dev database 
should be Oracle too! There is a free edition of Oracle (XE) which is 
just the job. Limited to 1 CPU, 1GB RAM, 4GB table space.
