There is no question that reusing reusable sql parses was a huge advance for scalability. But tossing non-reusable sql in the shared pool just puts extra pressure on the latches.

The shared pool came at the same time as database server pl/sql --- if I remember correctly. [there was forms pl/sql available earlier]

Was there co-development or dependency ?

In fact, why not parse all sqls with literals privately? It worked just fine in V6.

I wish that the ORA-4031 issue could be solved permanently
#IfWishesWereHorses
 

Is a solution to this problem beyond the capabilities of mortals?

Why is it necessary for a session to die if it cannot write to the shared pool? Why not just do what it needs to do even if it cannot share?
