Today, I noticed a performance problem on one of my databases. Statspack was showing quite a few of library cache waits. Most of the waiting sessions were trying to execute the same procedure and the problem was alleviated to significant degree by pinning the the package that contains the offending procedure, as well as all of the other PL/SQL objects belonging to FLOWS_03000.
Trouble is, I distinctly remember rading an article claiming that using DBMS_SHARED_POOL.KEEP is not good, that it is, in fact, obsolete. I can't locate the article so I will ask anyone who thinks that I shouldn't have done what I did, to explain me why? In other words, am I missing something or not? I have sufficient free memory, no danger of 4031 in the near future.
