I have gor some values form v$rowcache, I was wondering what are they
I mean I got
Parameter Gets GetMisses Count Hit Ratio
dc_histogram_data 10763 3153 14 70
dc_histogram_data_values 7661 1911 12 75
And the hit is to raise them.First of all I'd like to know what these
perameters refer to and then how could I raise the Hit?? What should I do?
What is the meaning of dc_histogram_data and dc_histogram_data_values??
the statistic collection either made too often or to rarely?
