Calculate execution time of procedure

hiii
I create procedure that insert data in multiple tables i want to calculate execution time of procedure the start time
and the end time to insert them in a table .
and i want to calculate the start&end time that the procedure take to insert in each table
i use DBMS_UTILITY.GET_TIME but it gives me in millisecond i want the format DD/MM/YYYY HH:MI:SS
i also use sysdate but it gives un un reasonable time
like the start time more than the end time
how to calculate execution time of procedure???????
thanks

Look at the docs for DBMS_PROFILER.

Execution time of procedures

How can find out the execution time of procedures.
I've debug and find why a procedure takes so much time for its execution.
Could someone please help me with tips or links to useful info.

First you can use the SQLPlus feature "set timing on" This will print the run time of each SQL or pl/sql procedure executed in the session.
Second you can modify the pl/sql code to include timing information so as the code runs it dumps and/or calculates step and procedure run time.
Third look at the dbms_profiler package Oracle provides.

How can i calculate execution time for methods?

I'm making a project that i want to calculate execution time for a
method in "miliseconds" or "microseconds".You see,I have a sort algorithm and i want to calculate execution time of this algorithm.How can i do?
Thanks...

Just remembered.
The answer you get isn't trustworthy below a hundred millis, so you may need to sort a hundred or a thousand times to get a reasonable elapsed time. You also need to run the test five or ten times and take an average. In Windows you should fire up the Task Manager and be sure that your other CPU usage is as near to zero as you can get.

How to calculate Execution Time

Hi gurus,
Can any one tell me how to calculate the Report Execution time in Seconds.
We have one requirement.My manager told me track all the reports in Development server how much time those take to execute. and Compare those with Production server.
I dont have an Idea how to calculate the Execution time in Seconds.
Please guide me on this.
Thanks in Advance
Thanks and Regards
Siri...

hi
check se30
enter the prog name and press execute.
after your execution is over press back
then press evaluate in the initial screen.
you have the analysis
in that you will get the time in microseconds and you can convert to sec

Execution time for web reports

Hello every one,
How to calculate execution time for web reports, for query execution we will go through RSRT, by giving query name and press execute + Debug button then select statistical data & Do not Cache buttons then press enter, after getting output press on back button, we will get duration of the query.....
But my question is , can we calculate execution time for webreport, if so can you please guide me.
and can you also tell me , if there is any RRI for one report, how to calculate execution time for these queries.
Ex : Query ABC have XYZ as its drilldown report , i need to calculate execution time for XYZ report via ABC report.
Thanks in advance,
Best Regards.

Hi,
For reports executed in java web you can add the parameter &PROFILING=X
to the URL in order to record the execution time. Please have a look at SAP note 1048691 for further information.

Best way to messure execution time???

Hi everybody,
I am trying to messure the time that takes an algorithm to be executed. I am using System.currentTime() at the begin and the end of the algorithm to calculate the time.
Is there another way to calculate execution time?
Thanks in advance,
JB

If you are on Windows (NT4 anyway) and want something more accurate, you can use this lil' bit of JNI:
// NanoTimer.java
package com.baesystems.tc.pete_kirkham.benchmark;
* Gets ~ nanosecond accuracy time
* @author Pete Kirkham
* @version 1.0
public final class NanoTimer {
   * Get a measure of the current elapsed time.
   * @return the time elapsed since an arbitary point in seconds.
public static native double currentTime ();
static {
    System.loadLibrary("nano_timer");
// nanotimer.cpp - compile to nano_timer.dll
#include <windows.h>
#include <winbase.h>
#include "com_baesystems_tc_pete_0005fkirkham_NanoTimer.h" // generated via javah
* Class:     com_baesystems_tc_saa_services_NanoTimer
* Method:    currentTime
* Signature: ()D
JNIEXPORT jdouble JNICALL Java_com_baesystems_tc_pete_1kirkham_benchmark_NanoTimer_currentTime
(JNIEnv *env, jclass cls) {
LARGE_INTEGER frequency;
LARGE_INTEGER counter;
if (QueryPerformanceFrequency(&frequency) && QueryPerformanceCounter(&counter)) {
    return (double)counter.QuadPart/(double)frequency.QuadPart;
} else {
    return 0.0;

Execution Times of Stored Procedures Called from Other Stored Procedures

If I execute sys.dm_exec_procedure_stats, it will produce execution times of my stored procedures executed recently.
However, stored procedures called from other stored procedures do not show up.
Is there code that can return the execution times of stored procedures even though they are called from other stored procedures.

Look at the example. It is counting nested execution.
CREATE PROC z1SP AS SELECT * FROM Production.Product;
GO
CREATE PROC z2SP AS SELECT * FROM Production.Product WHERE Color is not null; EXEC z1SP;
GO
SELECT object_name(2002822197), object_name(2034822311);

Procedure execution time difference in Oacle 9i and Oracle 10g

Hi,
My procedure is taking time on
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 is 14 min.
same procedure is taking time on oracle Release 9.2.0.1.0 is 1 min.
1) Data is same in both environment.
2) Number of records are same 485 rows for cursor select statement.
3)Please guide me how to reduce the time in oracle 10g for procedure?
i have checked the explain plan for that cursor query it is different in both enviroment.
so i have analysis that procedure is taking time on cursor fetch into statement in oracle 10g.
example:-
create or replace procedure myproc
CURSOR cur_list
IS select num
from tbl
where exist(select.......
EXECUTE IMMEDIATE 'ALTER SESSION SET SQL_TRACE = TRUE';
EXECUTE IMMEDIATE 'ALTER SESSION SET TIMED_STATISTICS = TRUE';
OPEN cur_list;
LOOP
FETCH cur_list INTO cur_list; -----My procedure is taking time in this statement only for some list number. there are 485 list number.
end loop;
TRACE file for oracle 10g is look like this:-
call count cpu elapsed disk query current rows
Parse 1 0.00 0.00 0 0 0 0
Execute 1 0.37 0.46 0 2 0 0
Fetch 486 747.07 730.14 1340 56500700 0 485

so Please guide me how to reduce the time in oracle 10g for procedure?
1) Is this envrionment setting parameter?
2) I have to tune the query? but which is executing fine on oracle 9i?
so how to decrease the execution time?
Thanks in advance.

Here i have one cron expression which says every 25 minutes, i want to have one function which will be passed with cron expression and time and function should return next execution time.
I was wondering if any ready function available for the same.
Thanks in Advance

How to know child procedure Execution time with in parent procedure

Hi Team,
I've a requirement in which I need to get the execution time of a child procedure while its running in a parent procedure in PLSQL. While the child process is running, I want to know its execution time so that if it execution time exceeds more than 5 seconds than I want to through an error. Please let me know by what means this can be achieved in plsql.
Regards,
Tech D.

Regards,
Tech D.PL/SQL is NOT a Real Time programming language.
The procedure that invokes the child procedure is effectively dormant while the child runs.
Plus there is no easy way to know when 5 seconds has elapsed.

Measure procedure execution time..

Hi,
Is there any possibility to measure how long each of a procedure in database take?? Is that possible for Oracle's V$ views or by performance report like AWR? On the other hand, is that possible to measure execution time for SQL statements, but without using "set timing on".
Best,

Long procedure execution time

Hello,
I hav a procedure which consists of select and insert statements(includes Union, Minus, DataType conversions etc.). Three tables of around 27 fields each, are involved in procedure. Table has around 87-90 lakhs of records. This procedure is taking around 7-8 hours for execution.
There is another almost exactly same procedure with tables of almost same fields, takes less than 5 minutes for execution. How can I optimize the previous procedure so that execution time is reduced.
Thanks.

Table has around 87-90 lakhs of records. 1 lakh is 100,000 records.
How can I optimize the previous procedure so that execution time is reduced.Without even knowing how the procedure looks, we can't comment or even able to help you. Apart from the number of columns and rows, we don't have any other information regarding your procedure or data or index.
Please elaborate so that anyone can help you.
Cheers

How can i check the procedure execution time..?

Hi All,
Can any one of you tell me how can i check the procedure execution time..?
Thanks in advance.

if running it from SQL*Plus,
SQL> set timing on
Or from PL/SQL, use DBMS_UTILITY.GET_TIME before and after the call and calclate the difference.

Calculate the execution time

Hi!,
I wanto to calculate what time Java need to do the execution of some methods...

You can use the system clock,
long time = System.currentTimeMillis();
// do something
System.out.println("Time= " + (System.currentTimeMillis()-time));The problem is the system clock has a resolution of about 1 millisecond. So you probably will have to call your methods many times and then calculate the average.
