In the second session I see, that logical reads have exceeded 200k and it still going further..

Question is:
Do I correctly compare statistic value of sesstat 'session logical reads' with 'LOGICAL_READS_PER_CALL' from profile?
If yes - Why had profile limit been ommited in the second case, while in the first there was a stop?

Answer 1

Have compared execution plans - they are the same.
Have made traces.

********************************************************************************After, I'de made serial test to determine the stop point and found that LOGICAL_READS_PER_CALL=116700
Which is very close to value in the following string of second trace:
  6446   COUNT STOPKEY (cr=116530 pr=0 pw=0 time=2127750 us)Well. I'm ready to admit, my understanding was wrong.
After some investigation, I've found, that 'CR' (consistrent reads) from trace refers to 'consistent gets' (While I queried 'session logical reads') wait from v$sesstat and in profile it is called 'LOGICAL_READS'.
Sorry, my fault.
