Memory is so cheap that you can afford to throw lots of it at it.

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) ).
