    how to do file house-keeping on windows 2003 

    Without “Forfiles” command, you maybe write a script with few hundred line, finally windows come with this handy command.

    This will delete .ARC files in d:\oraarch directory older than 10 days.

    Forfiles -p d:\oraarch -s -m *.arc -d -10 -c "cmd /c del /q @path"

    TCP High Performance Networking Options 

    High Performance Networking Options

    The options below are presented in the order that they should be checked and adjusted.

    http://www.psc.edu/networking/projects/tcptune/

    http://www.sean.de/Solaris/soltune.html

    Maximum TCP Buffer (Memory) space: All operating systems have some global mechanism to limit the amount of system memory that can be used by any one TCP connection. [more][less]

    Socket Buffer Sizes: Most operating systems also support separate per connection send and receive buffer limits that can be adjusted by the user, application or other mechanism as long as they stay within the maximum memory limits above. These buffer sizes correspond to the SO_SNDBUF and SO_RCVBUF options of the BSD setsockopt() call. [more][less]

    (More …)

    enable 4gb memory for vista 32bit 

    To force this new addressing method, you have to tell Vista to boot using this new parameter.  Vista no longer uses a BOOT.INI file as previous versions of Windows did, so you must modify the boot file using a built-in Vista tool called BCDedit.

    1. Open a command prompt (Press Window key + R to open the Run dialog, and then type cmd).
    2. Press Ctrl + Shift + Enter to execute (this allows you to run cmd in administrative mode if you haven’t already setup up a permanent admin mode).
    3. Type BCDedit /set PAE forceenable.

    This PAE flag (Physical Address Extension) tells the Vista core to use an additional 4 bits of addressing, which in theory allows the OS to see all of the RAM you have available.  We’re not out of the woods yet, because once you reboot you may find that Vista still doesn’t see all of your RAM.  You can turn PAE off again by typing BCDedit /set PAE forcedisable or BCDedit /set PAE default.
