I'd say that 7000 cursors is a bit much, so its no wonder your running out of them. See a previous post of mine. If you are going to use prepared_cached, then you MUST use placeholders. The variables belong in the execute() argument list, not in the SQL statement itself. See the DBI docs and What are placeholders in DBI, and why would I want to use them?

And especially with a database like Oracle, you should be using placeholders whenever possible whether you use prepare OR prepare_cached.
