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!
