Re: Oracle 10g on Windows 2003 x64 Memory Useage

Have you enabled large page support on Windows and Oracle, which
causes Windows to use 4MB memory page sizes rather than 4KB memory

information. I am running Oracle 10.2.0.2 on Windows 2003 x64, total
page file size for all drives is configured at 3124MB, yet Task
Manager reports that PF usage is 13.3GB. In my case, system
performance is great, so I am not too concerned about the inconsistent
numbers.

Have you verified that the page file is actually 10GB in size?



I have read quite a few of your posts and I think
that:

a) you know what you're talking about

and

b) you genuinely try to help people.


I hope that this info can help you and/or others.


For Windows, there is a nifty/cool/rad/awesome(for Yanks
only) - (choose term which hasn't gone out of fashion, or
better yet, the one which has come back into fashion!!)


Go to www.sysinternals.com and go for procexp (process
explorer).exe - it gives more reliable results than
the Windows performance monitor.



Inconsistent numbers should not happen. The site also
has a number of other useful bits and bobs for anyone
concerned with performance.
