No utility is going to fully account for memory usage in Windows. Process Explorer (a free download from Microsoft) is better than Task Manager but it does not show everything. Performance Monitor is also very good. Unless you have very specific need these should be more than adequate.

The problem for the large majority of users isn't a lack of information but knowing how to interpret the information. This isn't nearly as simple as it may appear.

I have this server with 32 gb of ram. The only big app on this is the oracle database. I have assign 15gb of sga + cache memory to it. The other apps running are small, like virus scanner. During the day, I would see the available ram goes to 200MB. Something is taking up all the memory. Its not the database, as only assign 15gb to it. I know that the OS usually uses 20% of the ram. Here is the math:

total ram (32gb) - ( db (15gb) + os (7gb) + other (2gb) ) = free (8gb)

So, my question is, -->> who is using the 8gb of memory?

Thanks.

You said that the OS uses 20% of RAM. Where do you get that number from? The memory manager will assign RAM dynamically to the OS as needed. This is never a fixed percentage.
Is this a 32 or 64 bit OS?

It would be very useful to see a screenshot of Task Manager - Performance tab.
Either that or provide all the memory related numbers, exactly as labeled.
