Hi All,

In 10g Oracle introduced view DBA_TAB_STATISTICS. Many columns are identical to those available
in DBA_TABLE (NUM_ROWS, LAST_ANALYZED), but there are new columns, in particular:

I checked a few databases and these columns don't get populated. It should be possible to get
this information from somewhere else - number of blocks from V$BH, V $CACHE and hit ratio from
object statistics. Still it would be nice to get these columns populated. Anyone know how to do it?
There is nothing in documentation.
