When I've wanted to do something like that I've been able to set up something to listen for database events. You can attach a small payload/message of up to 256 bytes when you raise them, which might be enough to send some argument. You need the listener to register for the event then react to any message. I rather doubt you can have a UDF even in 11.2+ that could run externals, but I would run screaming from the idea anyway. Roy
