Anything extra must have a cost, but I’ve only heard of a ‘compile’ tax for PL/SQL extend to debug information – as that causes overhead on EXECUTION of said procedures. I’ve never heard of any sort of performance tax for plsql objects with Scope data additionally stored in the data dictionary.

Of course, all things are easy to prove with some A vs B testing using something like LoadRunner or SwingBench.

The only downside I can think of is one thing that I've heard from one of DBA when I asked the same question to him. His concerns were:
- conpilation/recompilation time

I cannot confirm any of his concerns though.

Performance? Security? Anything?

If there are reasons not to do it in production, I'm considering giving out DBAs a script to turn it on for everything as part of their instance-cloning procedures, so it would be turned on in all non-production environments. That script would include an ALTER SYSTEM SET PLSCOPE_SETTINGS='IDENTIFIERS:ALL', so that PLScope data will be maintained as developers do their work. Any reasons this is a bad idea?

Thanks,
Matt
