We use a script to shutdown immediate (in sqlplus) all the DB's then
shutdown/bounce the box. On Windows, Oracle will perform crash recovery on
startup, but that was not acceptable since some DB's might be very busy
during shutdown and just didn't want to take the chance of a failed
recovery in production.

I would say yes this is accurate. Oracle is going to perform crash
recovery on startup so why worry about this?

Subject: Oracle shutdown on Wintel
We have a few Oracle databases running on Wintel.
In the past year, the Admins who take care of these Wintel hosts have
started to patching MS-Windows on a monthly basis.
So once-a-month we are going thru the routine of: download patches &
reboot.
What we are experiencing is that the Oracle database software on those
Wintel hosts is not shutting down gracefully. All we get is an error
message in the alert log, followed by the messages showing the database
being restarted.
I have talked to the guys who run MS-SQL databases and they are not
experiencing this problem; that is, their stuff is shutting cleanly with
each reboot.
I opened a case with Oracle support and got the following:
"The issue is addressed in bug 1912184 / bug 1638610.
The bug 1638610 has been identified as "Not Feasible to fix".
The reason for this is that once the Microsoft command to shutdown has
been issued, the dll security.dll is unregistered before the 'net stop'
command is given time to execute properly.
Oracle has no control over the algorithm used by Microsoft when Windows is
shutdown and thus cannot force adherence to the values of registry
parameter 'ORA_SID_SHUTDOWN' and by extension 'ORA_SID_SHUTDOWNTYPE' at
Windows shutdown time."
Is this accurate?
Is everyone running Oracle database software on Wintel living thru this
same scenario?
Thanks in advance.
