Hi List, i would like to know what exactly 'tim' value means in a '10046 event' trace file. (9iR2 on W2K) for example , what this means ? PARSE #1: tim=31028556368 is it the time(micro seconds) taken to parse ? (i don't think so.the query did not take so much time) OR is it the system time when the parse was done ? if so,how do i interpret it to a readable time format ? with Cary's book in front of me,i still can't get exactly what it is :( Regards, Prem.
