I had an issue this morning selecting data from an Oracle DB with MX 6.1. It looks like there are some known issues with the latest drivers. I found a post and spoke with an support engineer (thanks Stephen!) and after a roll back of the drivers, it all worked well. Hopefully we will see a real fix soon. I don't use Oracle often, so the Forums were a real help. If you don't use Macromedia's Support Forums, you are really missing out on a valuable resource. It's one of the best places to ask for, and search for help. I'd probably recommend it as the number two resource after cf-talk.
