I've got a bad code duplication problem where we cannot tell which versions of packages/procedures are being used. i.e. I have different packages with procedures of the same name and I need to be sure which packages are not actually being called.
I'm trying to eliminate procedures/packages of the same name which are no longer being called. I'd like to run the trace for a few weeks, combine the data and query the metadata against it and find candidates for further investigation and deactivation.
