There is a 4K limit on varchars. Check out the limits here: http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14237/limits001.htm

The NLS_LANG environmental variable can be very problematic as well. Good luck if you need more than one character set encoding. Due to using a legacy database where the developers decided it would be a good idea to store UTF-8 data in a Latin-1 encoding, I had to override the NLS_LANG parameter before the database is initialized. Since the database is initialized in the config/boot.rb file before environmental files are loaded, I had to put ENV['NLS_LANG']=’american_america.WE8ISO8859P1′ at the top of the boot.rb file.

You know you have bad encoding problems with oracle when you see “Je d??teste Oracle” like strings.

By the way, Oracle doesn’t support the SQL92 “set names” standard, nor can you do an alter session to change the character set encoding. Once the connection is made, there is no way to change the character set encoding, just the local information for sorting and formatting purposes.

I had wondered the other day if a Ruby -> Oracle connector existed. We do a significant amount of file processing, which might be much nicer in Ruby than Java.
