Doug - I would suggest that you start by trying to identify the worst
offenders in your SQL code. If modifying the source code is an option, you
can use Pareto's rule (80/20 principle) to identify the worst offenders. In
my experience, the worst troublemakers are batch reports that can flood your
SQL with non-reusable SQL that quickly ages out the good (reusable SQL).
Individual screens where users enter the occasional query with non-bound
variables
Once you exhaust the options for modifying code, or if your
situation won't let you use that option, take a look at the init.ora
parameter cursor_sharing=force. Be sure to read the available notes on this
because there are several caveats. This has been discussed several times on
this list, so search the archives. Personally, I would try the manual option
first, but I haven't tried the cursor_sharing=force alternative.

50% - pretty bad for a system that's been up for one week.
I checked and found that there were a few cases, blatent, that bind
variables
weren't being used. What's the next step? Increase the shared pool?
Is there any way I can monitor how often statements are being aged out?
Thanks.
