Re: TKPROF output -- high current gets for INSERT

The phrase "Elapsed times include waiting on following events:" comes from a
tkprof output, where the wait times are expressed in seconds (as opposed to
v$session_wait where they're in centiseconds (or micro in time_waited_micro
in 9i)).

Are there current gets associated with checking the referential integrity
(index is unusable but FK still in force)?

I checked the docs, according them that's centiseconds (100ths of a
second) 1192cs is 11.92s, close enought to 12 for government work.

Depends on the row size vs blocksize I suppose.  If the average row
size was 40k and block size was 2k that would explain the blocks per
row.  I'd hope that the poster would have said if that was a
possibility.
