Hi all,

Is it possible to keep one sql code to avoid parsing ?
I know we can keep a table is that possible for one sql ?
Do we need to set db_keep_cache_size or buffer_pool_keep ?

Thanks

This should not prevent from parsing, just from loading the package.
Let Oracle manages its shared pool; if the package is frequently used then it will be in memory, if it is not frequently used then why should it use memory that other can benefit?

So when we see that one sql is called frequently on statspack. What can we do to improve performance ? Should we store execution plan on outln user ?

Thanks.

Called? fetched, executed or parsed?
