USER HIT RATIO NOTES:
Username - Name of the user
Consistent Gets - The number of accesses made to the block buffer to retrieve data in a
consistent mode.
DB Blk Gets - The number of blocks accessed via single block gets (i.e. not through
the consistent get mechanism).
Physical Reads - The cumulative number of blocks read from disk.
Logical reads are the sum of consistent gets and db block gets.
The db block gets statistic value is incremented when a block is read for update and when segment header
blocks are accessed.
Hit ratio should be > 90%
