Hi Dwight, I wanted to throw out one note of caution. I completely agree with Roger: memory is too cheap to rob your system of it! However, you said you are running your TSM server on a Windows 2000 box. Remember, Windows limits application memory space to 2GB. This can be increased to 3GB with a startup option at the expense of some operating system memory spaces. (i.e. use it carefully!). Thus, you cannot allocate all 2GB to bufferpool cache as TSM still needs additional space for object creation, I/O buffering, and its own execution. We have found that we could only safely allocate 512-768MB to the bufferpool. If we incerased it beyond that, TSM would dump (go down HARD) when under load. While our DB is rather small (20GB - 40% utilized) we still get a hit of 99.9%. Other options are: Use different OS, use an Itanium-class server, talk IBM into adding AWE support when they write/compile TSM for windows (least likely I think <8) ).
