Copying Oracle List.
Thank you Jonathan for pointing out the anomaly which was the root cause
of the incorrect data getting displayed in the TKP file. The file that I
have also contain the same characters at the same location, which shows
that it somehow got corrupted during tracing.
Thank you,
Amir

Unless the trace file has been corrupted in zipping or in transit then the
problem is simply that a spurious batch of zero bytes has got into the file.
When I unzipped the file it held 447,145 lines
When I applied tkprof it reported " 116645 lines in trace file."
When I opened the file and jumped to line 116645 I saw the line after is
held 131 "^@" symbols, which I think is the representation of ascii 0 in vi
So one line of nulls got printed, and tkprof stopped when it hit them.
After deleting the line and re-running tkprof I got a summary showing:

Hi Cary,
Attached, please find the trace file in zipped format. I am also copying
Jonathan as he was the first person who had provided his feedback, in case
he would like to look at it as well.
Thank you,
Amir
