RE: What's Oracle Trying to Hide ???

Not quite true. Wrapped packages take same space (in fact more in dictionary cache
and same space in library cache).

Earlier versions of ORacle did not "wrap" the packages. Since the source code was available well meaning dba's decided to help Oracle by changing and recompiling these packages. This led to more than one corruption and many a confused support analyst. BTW, the wrapped package bodies supposedly take less space in the shared pool.
