Hi,
In my experience a large DB (60GB+) needs a big DB bufferpool
in order to perform well. We reckon on 2GB per TSM server.
There is little point in having much more than 2GB because
the server cannot use it (on AIX at least). I believe that
as distributed the TSM server code is built to utili

It depends upon the nature of the people in charge and organizational
