ORA-06528: Error executing PL/SQL profiler

Question

Hai
I would like to see the outcome of package (to view the report on the package).In order to get that
I installed the below package connect as internal
sql>d:\oracle\orq81\rdbms\admin\profload.sql
In order to use dbms_profiler,after that i need to have installed profilling tables ,in order to get i ran proftab.sql ,and its created three tables are
plsql_profiler_data,plsql_profiler_units,plsql+profiler_runs
after that i ran the below procedure
create or replace procedure do_mod as
cnt number := 0;
begin
dbms_profiler.start_profiler( 'mod' );
for i in 1 .. 500000
loop
cnt := cnt + 1;
if ( mod(cnt,1000) = 0 )
then
commit;
end if;
end loop;
dbms_profiler.stop_profiler;
end;/
PL/SQL procedure successfully completed.
exec no_mod
PL/SQL procedure successfully completed.
In order to see the report on packge ,i had query the table , RUN_TOTAL_TIME IS 3.5190E+11(this is seconds)
my qusetion is
1)
Please explain me that is total amount time in seconds or minutes,i donnot understand what is 3.5190e+11
SQL> select RUNID,RUN_COMMENT,RUN_TOTAL_TIME FROM PLSQL_PROFILER_RUNS;
RUNID
RUN_COMMENT
RUN_TOTAL_TIME
1
mod
7.0975E+11
2
mod
6.9767E+11
RUNID
RUN_COMMENT
RUN_TOTAL_TIME
3
no mod
3.5190E+11
2)
I had ran the above script one of the schema ,and successfully created above procedure.When i execte,it retuns below error message

Answer 1

1) Run_total_time is the elapsed total time in nanoseconds.
   A nanosecond is one billionth of a second.
   It is displayed in scientific notation
   where E stands for "times ten to the power of".
   So, 3.5190E+11 nanoseconds
     = 3.5190 * 100000000000 nanoseconds
     = 351900000000 nanoseconds
     = 351900000000 billionths of a second
     = 351900000000 / 1000000000 seconds
     = 351.9 seconds
   If you want to display it in seconds, use:
     SELECT runid,
            run_comment,
            run_total_time / 1000000000 AS seconds
     FROM   plsql_profiler_runs;
2) The only thing that looks wrong about your do_mod procedure
   is the last line:
     end;/
   The / should be on the next line.
   Other than that, I don't see any possible cause for
   the error.
