Explanation for DB parameter settings with version 8.

Hi,

I would like to get hold of some documentation that explains the "DB2 Profile registry" parameters and also provides an insight into performance aspects when these parameters are changed.

For example-

CATALOGCACHE_SZ

LOGBUFSZ

UTIL_HEAP_SZ

BUFFPAGE

LOCKLIST

DB2_REDUCED_OPTIMIZATION

DB2_INLIST_TO_NLJN

DB2_MINIMIZE_LISTPREFETCH

DB2_ANTIJOIN

DB2_EVALUNCOMMITTED

Though standard SAP Notes are available that provide start up values for the above parameters, i would like to get documentation explaining the purpose of these parameters and their impact on performance.

thanks for your time.

regards

shaibal
