Execution time in microseconds

Hi,
Can someone tell me what should be the ideal execution time of a program in microseconds. My program consists of 2586 lines and has almost around 10 subroutines and some 10 function modules. Could you suggest me how the execution time is determined for a program.
Thanks,
Binay.

You can use simple command like
declare three variables :
data : a Type i,
b type i,
c type i.
start-of-selection.
Write the command in staring
get runtime field a. -> will have intial start time
write the one more command in last
get runtime field b. -> this is final time
c = b - a. -> c will have total execution time in micro seconds
or
you can use ST05 Transaction to find out the time,here you need count the all times.
Thanks

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

Retrieve Computer time in microsecond

to retrieve computer time i use the function System.currentTimeMillis() but i need the time in microsecond. how could i get that?

<snip>
Java 1.5 added nanosecond methods for hardware/OS
combinations that can support it.Which at current includes none at all :)<snip>
Are you saying that System.nanoTime() isn't supported at the present time?
That's not correct - I am running a 3 GB Pentium 4, a relatively recent GigaByte m/b and XP Pro, and get very good microsecond and submicrosecond results from the method.
I executed 2 consecutuive calls to the method, like so
startTime = System.nanoTime();
estimatedTime = System.nanoTime() - startTime;and averaged 100 repetitions.
Results vary with the manner in which the jvm is executed. Here's a summary of results, to give a feel for what's possible.
Program Execution From        Nanoseconds (average)
Commandline                     1300
CrimsonEditor                    500
jEdit                            700
NetBeans IDE 4.1                1050So, depending on the method of execution, nanosecond precision ranges from 500 to 1300 (0.5 microsecond to 1.3 microsecond). Accuracy (repeatability) is not as good - there are outliers in the individual times, probably due to Garbage Collections. However excluding those outliers, times appear reasonably repeatable.

Top Sqls by Execution time

Hi,
Can you please provide a query which gives top 5 SQLs ordered by Execution time ( i.e Elapsed Time/No of Executions), for one day.
Appreciate your help.
Thanks

Hi,
welcome to the forum!
Here is the query:
select sql_id, sum(elapsed_time_delta)/1e6 total_elapsed_seconds, sum(executions_delta) total_executions
from dba_hist_sqlstat st,
dba_hist_snapshot sn
where st.snap_id = sn.snap_id
and sn.begin_interval_time between sysdate-1 and sysdate
group by sql_id
order by 2 desc;Keep in mind that in order to use it you need the diagnostic pack license.

Sorry i have tried to format the code, but it has changed to �... sorry read this one...
Hello All,
I'm making a Java SQL Client. I have practicaly all basic work done, now I'm trying to improve it.
One thing I want it to do is to allow the user to specify new drivers and to use them to make new connections. To do this I have this class:
public class DriverFinder extends URLClassLoader{
private JarFile jarFile = null;
private Vector drivers = new Vector();
public DriverFinder(String jarName) throws Exception{
super(new URL[]{ new URL("jar", "", "file:" + new File(jarName).getAbsolutePath() +"!/") }, ClassLoader.getSystemClassLoader());
jarFile = new JarFile(new File(jarName));
System.out.println("-->" + System.getProperty("java.class.path"));
System.setProperty("java.class.path", System.getProperty("java.class.path")+File.pathSeparator+jarName);
System.out.println("-->" + System.getProperty("java.class.path"));
Enumeration enumeration = jarFile.entries();
while(enumeration.hasMoreElements()){
String className = ((ZipEntry)enumeration.nextElement()).getName();
if(className.endsWith(".class")){
className = className.substring(0, className.length()-6);
if(className.indexOf("Driver")!=-1)System.out.println(className);
try{
Class classe = loadClass(className, true);
Class[] interfaces = classe.getInterfaces();
for(int i=0; i<interfaces.length; i++){
if(interfaces.getName().equals("java.sql.Driver")){
drivers.add(classe);
Class superclasse = classe.getSuperclass();
interfaces = superclasse.getInterfaces();
for(int i=0; i<interfaces.length; i++){
if(interfaces[i].getName().equals("java.sql.Driver")){
drivers.add(classe);
}catch(NoClassDefFoundError e){
}catch(Exception e){}
public Enumeration getDrivers(){
return drivers.elements();
public String getJarFileName(){
return jarFile.getName();
public static void main(String[] args) throws Exception{
DriverFinder df = new DriverFinder("D:/Classes/db2java.zip");
System.out.println("jar: " + df.getJarFileName());
Enumeration enumeration = df.getDrivers();
while(enumeration.hasMoreElements()){
Class classe = (Class)enumeration.nextElement();
System.out.println(classe.getName());
It loads a jar and searches it looking for drivers (classes implementing directly or indirectly interface java.sql.Driver) At the end of the execution I have found all drivers in the jar file.
The main application loads jar files from an XML file and instantiates one DriverFinder for each jar file. The problem is at execution time, it finds the drivers and i think loads it by issuing this statement (Class classe = loadClass(className, true);), but what i think is not what is happening... the execution of my code throws this exception

How to get the execution time of a Discoverer Report from qpp_stats table

Hello
by reading some threads on this forum I became aware of the information stored in eul5_qpp_stats table. I would like to know if I can use this table to determine the execution time of a worksheet. In particular it looks like the field qs_act_elap_time stores the actual elapsed time of each execution of specific worksheet: am I correct? If so, how is this value computed? What's the unit of measure? I assume it's seconds, but then I've seen that sometimes I get numbers with decimals.
For example I ran a worksheet and it took more than an hour to run, and the value I get in the qs_act_elap_time column is 2218.313.
Assuming the unit of measure was seconds than it would mean approx 37 mins. Is that the actual execution time of the query on the database? I guess the actual execution time on my Discoverer client was longer since some calculations were performed at the client level and not on the database.
I would really appreciate if you could shed some light on this topic.
Thanks and regards
Giovanni

Thanks a lot Rod for your prompt reply.
I agree with you about the accuracy of the data. Are you aware of any other way to track the execution times of Discoverer reports?
Thanks
Giovanni

How to get the total execution time from a tkprof file

How to improve the execution time of my VI?

My vi does data processing for hundreds of files and takes more than 20 minutes to commplete. The setup is firstly i use the directory LIST function to list all the files in a dir. to a string array. Then I index this string array into a for loop, in which each file is opened one at a time inside the loop, and some other sub VIs are called to do data analysis. Is there a way to improve my execution time? Maybe loading all files into memory at once? It will be nice to be able to know which section of my vi takes the longest time too. Thanks for any help.

Bryan,
If "read from spreadsheet file" is the main time hog, consider dropping it! It is a high-level, very multipurpose VI and thus carries a lot of baggage around with it. (you can double-click it and look at the "guts" )
If the files come from a just executed "list files", you can assume the files all exist and you want to read them in one single swoop. All that extra detailed error checking for valid filenames is not needed and you never e.g. want it to popup a file dialog if a file goes missing, but simply skip it silently. If open generates an error, just skip to the next in line. Case closed.
I would do a streamlined low level "open->read->close" for each and do the "spreadsheet string to array" in your own code, optimized to the exact format of your files. For example, notice that "read from spreadheet file" converts everything to SGL, a waste of CPU if you later need to convert it to DBL for some signal processing anyway.
Anything involving formatted text is not very efficient. Consider a direct binary file format for your data files, it will read MUCH faster and take up less disk space.

How to find out the execution time of a sql inside a function

Hi All,
I am writing one function. There is only one IN parameter. In that parameter, i will pass one SQL select statement. And I want the function to return the exact execution time of that SQL statement.
CREATE OR REPLACE FUNCTION function_name (p_sql IN VARCHAR2)
RETURN NUMBER
IS
exec_time NUMBER;
BEGIN
--Calculate the execution time for the incoming sql statement.
RETURN exec_time;
END function_name;
/

Please note that wrapping query in a "SELECT COUNT(*) FROM (<query>)" doesn't necessarily reflect the execution time of the stand-alone query because the optimizer is smart and might choose a completely different execution plan for that query.
A simple test case shows the potential difference of work performed by the database:

Need to know how to find the last execution time for a function module

HI all
I need to know
1) How to find out the last execution time of the function module ?
say for eg. I have executed a func. module at 1:39pm. How to retrieve this time (1:39pm)
2) I have created 3 billing document in tcode VF01 i.e 3 billing doucment no. would be created in SAP TABLE "VBRP" b/w 12am to 12:30 am.
How to capture the latest SAP database update b/w time intervals?
3) Suppose I am downloading TXT file using "GUI_DOWNLOAD" and say in 20th record some error has happened. I can capture the error using the exception.
Is it possible to run the program once again from 21st records ? All this will be running in background...
Kindly clarify....
Points will be rewarded
Thanks in advance

1.Use tcode STAT input as Tcode of Fm and execute .
2. See the billing documents are created in table VBRk header and there will always be Creation date and time.
VBRk-Erdat "date ., u can check the time field also
So now if u talk the date and time we can filter then display the records in intervals.
3. with an error exeption how is my txt download finished .
once exception is raised there will not be a download .
regards,

Plz help me. It's a very urgent report...

I think you are using for all entries statement in almost all select statements but i didnt see any condtion before you are using for all entries statement.
If you are using for all entries in gt_opbal ... make sure that gt_opbal has some records other wise it will try to read all records from the data base tables.
Try to check before using for all entries in the select statement like
if gt_opbal is not initial.
select adfda adfadf afdadf into table
for all entries in gt_opbal.
else.
select abdf afad into table
from abcd
where a = 1
    and b = 2.
endif.
i didnt see anything wrong in your report but this is major time consuming when you dont have records in the table which you are using for all entries.

Reduce execution time with selects

Hi,
I have to reduce the execution time in a report, most of the consumed time is in the select query.
I have a table, gt_result:
DATA: BEGIN OF gwa_result,
      tknum            LIKE vttk-tknum,
      stabf            LIKE vttk-stabf,
      shtyp            LIKE vttk-shtyp,
      route            LIKE vttk-route,
      vsart            LIKE vttk-vsart,
      signi            LIKE vttk-signi,
      dtabf            LIKE vttk-dtabf,
      vbeln            LIKE likp-vbeln,
      /bshm/le_nr_cust LIKE likp-/bshm/le_nr_cust,
      vkorg            LIKE likp-vkorg,
      werks            LIKE likp-werks,
      regio            LIKE kna1-regio,
      land1            LIKE kna1-land1,
      xegld            LIKE t005-xegld,

And the select query is this:

                         INNER JOIN vttp AS tp ON tktknum = tptknum
                         INNER JOIN likp AS tl ON tpvbeln = tlvbeln
                         WHERE l~/bshm/le_nr_cust IS NULL )

                    AND ( nregio = '51' OR nregio = '52'
                          OR nregio = '35' OR nregio = '38' ) )
                           OR n~land1 = 'ESC' ) )
                  OR ointca = 'AD' OR ointca = 'GI' ).
Does somebody know how to reduce the execution time ?.
Thanks.

Hi,
Try to remove the join. Use seperate selects as shown in example below and for the sake of selection, keep some key fields in your internal table.
Then once your final table is created, you can copy the table into GT_FINAL which will contain only fields you need.
EX
data : begin of it_likp occurs 0,
         vbeln like likp-vbeln,
         /bshm/le_nr_cust like likp-/bshm/le_nr_cust,
         vkorg like likp-vkorg,
         werks like likp-werks,
         kunnr likr likp-kunnr,
       end of it_likp.
data : begin of it_kna1 occurs 0,
       kunnr like...
       regio....
       land1...
      end of it_kna1 occurs 0,
Select tknum stabf shtyp route vsart signi dtabf
from VTTP
into table gt_result
WHERE tknum IN s_tknum AND
      tplst IN s_tplst AND
      route IN s_route AND
      erdat BETWEEN s_erdat-low AND s_erdat-high.
select vbeln /bshm/le_nr_cust
       vkorg werks kunnr
       from likp
       into table it_likp
       for all entries in gt_result
       where vbeln = gt_result-vbeln.
select kunnr
       regio
       land1
       from kna1
       into it_kna1
       for all entries in it_likp.
similarly for other tables.
Then loop at gt result and read corresponding table and populate entire record :
loop at gt_result.
read table it_likp where vbeln = gt_result-vbeln.
if sy-subrc eq 0.
move corresponding fields of it_likp into gt_result.
gt_result-kunnr = it_likp-kunnr.
modify gt_result.
endif.
read table it_kna1 where kunnr = gt_result-vbeln.
if sy-subrc eq 0.
gt_result-regio = it-kna1-regio.
gt_result-land1 = it-kna1-land1.
modify gt_result.
endif.
endloop.

Oracle - select execution time

hi all,
when i executed an SQL - select (with joins and so on) - I have observed the following behaviour:
Query execution times are like: -
for 1000 records - 4 sec
5000 records - 10 sec
10000 records - 7 sec
25000 records - 16 sec
50000 records - 33 sec
I tested this behaviour with different sets of sqls on different sets of data. But in each of the cases, the behaviour is more or less the same.
Can any one explain - why Oracle takes more time to result 5000 records than that it takes to 10000.
Please note that this has not something to do with the SQLs as - i tested this with different sets of sql on different sets of data.
Can there be any Oracle`s internal reason - which can explain this behaviour?

That is not normal behaviour. I've never come across anything like that that wasn't explainable by some environment factor (e.g. someone else doing a big sort).
I ran a couple of tests:
(1) to insert 5000 rows 0.1 seconds
to insert 10000 rows 0.18 seconds
and
(2) to select 5000 rows joined with 200K row table 0.19 seconds
to select 10000 rows joined with 200K row table 0.2 seconds
Although the second is close, I grant you!
Cheers, APC
