dba_object_size only shows some fixed calculations from stored code (how big is the code segment etc..), but it doesn't show how much memory a loaded object actually uses in shared pool.

If you want to know library cache usage, use v$db_object_cache or x$kglob directly.

If you want to know shared pool usage, then you have to start taking shared pool heapdumps....

On a side note, before I kill myself with the Friendly Manual, does anyone have a fast way to determine how much space in the shared pool a package is using?

Is there a way to catch shared_pool fragmentation before you get the 4031 errors? I have looked at Steve Adams site which has scripts to show the free lists chunks in the shared pool. At what point do I know that it is fragmented too much? I know that I can prevent this by using bind variables, and keeping objects, but until I can modify all the apps, I would like to know a little before these errors happen. Any ideas?

Thanks,

Rick Stephenson
