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.
