Also make sure your max_dump_file_size is big enough so that the file doesn't get closed by the size limit before the STAT lines can be written to it. Regards, Brandon ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Stefan Knecht The STAT lines (row source operations) only get dumped in the tracefile when the cursor gets closed. If, for example, you're tracing a running session for a short period of time, you may not get any plans in the tracefile (and hence in tkprof).
