In order to increase the DB buffer Cache there are two parameters in the
init.ora file. The DB_BLOCK_SIZE and the DB_BLOCK_BUFFERS. You will
increase the DB_BLOCK_BUFFERS and multiply it by the DB_BLOCK_SIZE to get
the size of the cache.

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.
