hi,
what is the error?
i believe its mostly becuase of PATH setttings.
u need to execute tkprof from the OS prompt.
simplest way is to go to the trace directory,
execute the command. by default, tkprof.exe should be accessible anwhere from $ORACLE_HOME.
from the docs
Examples of TKPROF Statement
TKPROF Example 1
If you are processing a large trace file using a combination of SORT parameters and the PRINT parameter, then you can produce a TKPROF output file containing only the highest resource-intensive statements. For example, the following statement prints the 10 statements in the trace file that have generated the most physical I/O:
TKPROF ora53269.trc ora53269.prf SORT = (PRSDSK, EXEDSK, FCHDSK) PRINT = 10
TKPROF Example 2
This example runs TKPROF, accepts a trace file named dlsun12_jane_fg_sqlplus_007.trc, and writes a formatted output file named outputa.prf:
TKPROF dlsun12_jane_fg_sqlplus_007.trc OUTPUTA.PRF
EXPLAIN=scott/tiger@prod1 TABLE=scott.temp_plan_table_a INSERT=STOREA.SQL SYS=NO
SORT=(EXECPU,FCHCPU)
This example is likely to be longer than a single line on the screen, and
