Hallo TSMers.



Question:



If the DB Package Cache Hit Ratio  is low, besides HW- and OS-tuning, where
can I tune / use Parameters

for DB2 (" TSM") to influence overall performance. Is there something more
than "just" the dbmempercent option ?



(In the DB2 documentation I found as an example also    "pckcachesz -
Package cache size configuration parameter". But as a non-DB2 expert,

I'm first not sure about the effects and second I know of course, that I
should not change TSM DB2 settings as long as it is not officially endorsed
by TSM support).

Thanks in advance for ideas
