How can I see where all my memory go on my window server 2003? Task manager or perfmon does not show all. thx
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.
Click on Performance Monitor. Click on Green colored “Plus” Symbol to open add counters Window. To select Memory, search the list of counters and select Memory, click on Add button and then OK button. When the graph appears on the screen, the graph will indicate memory usage.
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.
