TSM v4.2.1, sun 3500, solaris 2.8, 2gb memory, 288gb disk.

Currently have a database of approximately 6.5gb at 77% utilization.  Dbbufsize 
is currently set at 192mb.  Cash hit starts out very good at 99-99.5% but 
creeps downward throughout a weeks run to around 97%.

I have looked in the admin guide, and they recommend a cash hit ratio of over 
98%.  However, no matter what I try, I can never seem to hit it.

Any suggestions welcome.
