I want to format the output gathered in the tables PLSQL_PROFILER_UNITS and PLSQL_PROFILER_DATA after executing the relevant functions of DBMS_PROFILER package

I tried using the script profsum.sql (copied profsum.sql and profrep.sql from ..\ORANT\plsql\demo) to generate the report

But the script does not give the expected result
It gets hanged max of the times

I tried to comment out some queries in the script where I suspected the problem could be
But could not get thru

Can anybody provide me the scripts for the same purpose
Script should display the performance informance, coverage information etc

Thanks and Regards,
