Maybe I'm missing something here, so comments are welcome.    If these 6 to 8 
are used frequently, then they will never page out from the LRU list no?  so in 
essence will always be in memory, (or at least almost all of the time).

So....  are we not complicating something that is essentially not needed?

Subject: Pinning Packages on the shared pool

Lists,

Our appliction team has requested (as per vendor's recommendations), to pin the 
frequently used packages (around 6 to 8 packages) on the shared pool. We 
thought of pinning the packages using the DB Startup trigger, so every time DB 
recyles, those packages gets included on the memory. Is there any other better 
way of handling this rather than using the startu trigger. Any advice is highly 
appreciated.

Thank you,
Prabhu
