I have Oracle 11.0.1.0 over Windows 2008.
Yesterday we had to bounce the instance due to an ora-04031 error caused by
the Automatic Memory Management system, the error is solved by patching to
11.0.2.0 or higher (that's not the problem now).
The main problem is that after bounce (I had to kill the oracle.exe service
as I couldn't even connect with sys account), the DB it's beeing so slow.
Checking the OEM Performance, I have found that the reason is a very high
I/O (virtual memory), but the difference in use is huge!
The I/O was very low and constant before the bounce (at least on the last
10 days), but now has growth about 3 or 4 times.
I've found some high I/O queries that I have tuned, but they were running
faster before the bounce, any idea?
I have red that some people has have similar problems but under Solaris,
seems like it's only solved after bouncing the server, not only the
instance.
Any inputs are appreciated.
