index bufferpool measurement
I increased the user data and index bufferpool last week.
How can I tell what improvement percentage we got after the increase in bufferpool from Insight?
Every Field is important in its own way and provides an Insight into Buffer Pool Performance.
What is very good in CA Sysview for DB2 is the Field Level Help.
If you put your cursor on a column and hit PFK1 (help) not only do you get very detailed field information you will get tuning hints and tips.
The first three columns i would suggest you review are "Hit Ratio" "Sync RD I/O" and "Getpgs" but do review the Field level Help on all columns
