I want to see the "wait events" along with my cost for a particular query. My environment: Sun Solaris (SUNOS 5.9) Oracle 9.2.0.7 TIMED_STATISTICS is not set in the parameter file.... So, I am doing SQL> alter session set sql_trace=true; SQL> alter session set timed_statistics=true; SQL> "running the SQL here" After getting the trace: $ tkprof <trace file> <output file> explain=... sys=no waits=yes But the "output file" never produces the "wait events" Any ideas?
