DB_BLOCK_BUFFERS I have the NT 8i Tuning & Performance guide, which goes in to this in a bit of detail.

OK, so I have a new utility to monitor overall SGA usage. Breaks it down to show statistics on the major components.

Nothing that unusual, but, I notice that 'Buffer Cache Hit Ratio' is low from my perspective (78.56%). 'Library Cache Hit Ratio' is running at 97.54%, while 'Data Dictionary Cache Hit' is running at 96.11%. I would like to increase 'Buffer Cache Hit Ratio' to about 93-95% but am unsure which SGA parameter I need to increase.

Thanks for your assistance.
