    Question Unanswered: Virtual Memory Paging

    I am having Oracle 10g on Windows 2003 server (EE). Following are server details:-
    1)RAM :- 16GB
    2)CPU :- Dual core 4 cpu
    3)Pagefile size :- 20GB (Distributed across C,D & E drives. Out of which C drive is FAT32 & others have NTFS file system.)

    I am facing performance issue. I am getting following message thru OEM:-
    Significant virtual memory paging was detected on the host operating system.
    Host operating system was experiencing significant paging but no particular root cause could be detected. Investigate processes that do not belong to this instance running on the host that are consuming significant amount of virtual memory. Also consider adding more physical memory to the host.


    What could be the cause?
    Also please tell me what should be the cpu_count parameter in my case?

    32 or 64 bit h/w and/or OS? which for both?

    Is any other s/w or application running on this system?

    You can lead some folks to knowledge, but you can not make them think.
    The average person thinks he's above average!
    For most folks, they don't know, what they don't know.
    Good judgement comes from experience. Experience comes from bad judgement.

    Server is a 64bit. OS is also 64bit. On this server only Oracle is running.
    But still I am getting Virtual Memory Paging message.

    I presume your using 64 bit windows in which case this should be of use to you.

    I would have thought with 8 cores that is what you should set your cpu count to.
