Hello!
I just wanted to thank everyone for suggestions and help with this matter!
I changed the bufpoolsize to 419430, which is 10% of the physical memory,
and then reset the bufpool and now my cache hit % is 100%. At this point,
until I see otherwise, I am going to conclude that I had the bufpoolsize
setting too high at 524288. I will continue to monitor the cache hit % of
the database, but I believe the problem to be solved. Thank you again!

What is your buffpool setting? Run "query option" and look for the
buffpoolsize. Look in the dsmserv.opt file and read the comments about
this parameter, then look in the server manual for this too.

Cache Hit % below 99%
Hello All!
I have noticed that the cache hit % is below 99%. This is a newly defined
TSM 5.2.2.5 server on an AIX 5.2 OS. Are there any special
parameters/definitions that could contribute to the percentage being so
low? Thanks!
