Hi all, Does anybody know how to use the TKPROF command to format and analize a trace file generated by SQL?. I generated a trace file named: prt_ora_12733.trc, I am trying to get some detailed information because the trace file is quite big, but I get an error in SQLPLUS when I try to do the following: TKPROF prt_ora_12733.trc output.prf Isabel Bedoya Gómez Centro de Gestión y Control Tel. 2307500 ext:
