Recommendations:
1) apply maintenance regularly after testing it don't hang on some base release
aka 11.1.0.1.0
2) reboot the server after getting an rman backup and verifying that backup
completed.

Subject: DB slow after bounce (Windows)
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.
