Molianro ("you developer, you"),
You leave the "bouncing the db" to the DBAs! hehe. However, we shutdown our databases monthly and take offline backups and full exports. This also includes shutting down completely our Solaris and Windows servers. It does seem to help. Everything seems to run faster and some bugs go away. I always say: "The bugs went away because the "developers" (Oh my! Phew!) fixed their code! hehe.

Subject: bouncing the db?
hello dba's,
I have a question that I am hoping you can help with.
We have different rdbms at my company and as expected
each one is treated differently.
from our experience (well, from the suggestion of sql server
consultants)
its good to bounce the sql server databases every so often.
now, I've never done this with oracle but I am wondering
if any of you have.
I am ofcourse aware of the various drawbacks to bouncing
the db (such as flushing the caches making all new sql hard parsed)
but it would be done at our maintenance window (so, no worries
about users and their sql).
over the last 6 months we've hit some bugs with oracle that neither
I nor oracle support have been able to really fix (we're talking
severity 1 tar here, so, very senior support analysts working with
me to resolve various problems as we got nowhere).
in some cases (magically) bouncing the db
(at the suggestion of support) has helped.
I'm not crazy about doing this all the time but if it saves me
from all-nighters and rebuilding production from standby via
failover (which is a total pain as our db's are ~1tb) then I'll do
it.
this would be a monthly thing or every other month.
so, we're talking 6 - 12 bounces a year.
any feedback (good or bad) would be appreciated.
thanks guys/gals,
Anthony
