Hi,
Is there any possibility to know how much parse codes are present in shared pool?

what is the advantage of using bind variables?

Thanks.

Hi Michel,
Thanks for that info.
Is it possible to clear parse codes? Is there any LRU algorithm implemented in shared pool?
Hope this parse codes are present in library cache

Thanks.

1/ No specific clear possible. "alter system flush shared pool" clears all
2/ Yes there is something like a LRU algorithm
3/ SQL area is in the library cache.
