Procedure/Function execution time

I want to get my procedure/function total execution time which is running inside of application.
I think that I can use PLSQL_EXEC_TIME column of v$sql time. Please confirm this if I can or not.

"IMAQdxOpenCamera" function execution time is particularly long,why?

I install VAS2011 in CVI2010 environment, running IMAQdx the samples <Grab and AttributesSetup>, "IMAQdxOpenCamera" function execution time is particularly long, more than 7 seconds，why?
Thanks!

Thank you for your answers!
I capture video using VFW initialization faster, only use IMAQdx speed slow.

Procedure/function execution sequence

Hi,
I've a package that has about 20 stored procedures & functions and I know these are executed sequentially but don't know which procedure/function is called when and in what order.
Is there a way for me to query some Oracle table to check the sequence in which these procedures or functions are called during the last execution?
I understand, it can also be achieved by logging messages but am wondering if there's a Oracle table that stores this information.
Thanks in advance.

If you can start the dbms_profiler before the procedure is executed and stop the dbms_profiler after the procedure is finished. It will give you each statement which gets executed in sequenc.
NOTE: The source code should be unwrapped.

CVI XML Functions Execution Times Increase When Looped

I have written multiple functions using CVI that read XML files. I have confirmed in the Resource Tracking utility that i have cleaned up all of my lists, elements, documents, etc. I have found that when I loop any of the functions I have created, the execution times increase. The increase is small but it is noticable and does effect my execution.
Are there any other sources of memory that I need to deallocate? It seems that there is a memory leak somewhere but I am unable to see where this increase is located.
I am currently running LabWIndows/CVI 2009 on Windows 2008 Server. I have looped my functions using TestStand 4.2.1. Any help would be appreciated!
Thanks in advance,
Kyle

HI Daniel,
Thanks for the quick response.
It is indeed slow down in execution speed when we loop. When looped, the XML reader is overwriting variables, not adding to an array. Our application is structured differently than my test case. We run a CVI function from TestStand that contains a series of commands, which contains the XML reading. The XML looping is really done in CVI. I used TestStand in my test case just to get execution times. Our psuedocode for the CVI function is as followed:
For loop (looping over values, like amplitude or frequency)
Reading the XML
Applying the data from the XML to set up some instrument(s)
Do something...
End loop
I can confirm that the instrument set up is not the cause of the slow down. We have written the same XML reading in C# and applied the values to the instrument setup and do not experience the slow down.
I tested with On-The-Fly Reporting enabled and the execution time continued to slow down.
I hope that answers all of your questions!
Thanks,
Kyle

Get Stored Procedure Last Execution time.

Hi,
I am looking to get last execution of store proc(My cache is flushed off). So would like to know all the store proc execution times.
sys.dm_exec_query_stats( as I known gets from cache, now all my cache is flushed)
Is there any way out.
N_14
Naveen| Press Yes if the post is useful.

You may need to look at sys.dm_exec_procedure_stats.
As your cache is flushed, you will be unlikely to get this information without manual logging.

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:

You need to actually fetch all records, e.g. using a PL/SQL block on the server to find out how long it takes to process the query, but that's not that easy if you want to have an arbitrary query string as input.

Oracle Execution Time for function inside view

Hi Guys,
i would like to ask if i call a function inside a view , how does it behave in term of execution time and performance
For Example i have a view as below
create or replace view CUST.CUST_VIEW
select a.nice , a.getCustomDisplay(a.name,a.pin,a.dos,b.master_key) as custom from CUST.customer as a , CUST.master as b
where a.idno = b.main_id_no
AND the function look like this
create or replace function getCustomDisplay(a varchar2,b varchar2,c varchar2,d varchar2)
begin
select * from CUST.MAPPING_MATRIX order by idno asc;
for loop
//logic goes here to determine the result return from matrix
end
My Question is for example
1. If i do select * from CUST.CUST_VIEW ( return 1000 records for example ) , so the function getCustomDisplay will be executed 1000 times also right ( that means select * from CUST.MAPPING_MATRIX order by idno asc; will also be executed 1000 times ) ?
2. If i do select * from CUST.CUST_VIEW where rownum <= 20 , how many times getCustomDisplay() function will be executed ?
The reason i ask this because recently we saw a few million execution times per day from AWR report for this query
"select * from CUST.MAPPING_MATRIX order by idno asc;"
But when i investigate , and put a logger whenever it call getCustomDisplay , the query above as mention in item no 2 only will be executed as many as the record that will be returned from ( view + where condition ).
3. will it affect performance if my view return a lot of records ? or is there any way to improve it?
Thanks

Hi
i have other solutions that seems work for reducing number of execution times but do you think its scalable and feasible ?

the key point is the initializeTypePassMatrix function but it seems the variable only works for one session ?
if i open new session it will be reset again .

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,
vijay

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

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.

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 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.

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.

Execution time for Call Library Function Node

I am experimenting with the Call Library Function Node block in LabVIEW and am curious if it should be running faster than what I'm seeing. For testing purposes, I have compiled and transfered to my RT target the .out file from the KB article http://digital.ni.com/public.nsf/allkb/81D1172E3C28A5E4862575CC0076A230 (I'm using the vxworks 6.1 version). The function in the .out file just multiplies two inputs together, adds a constant, and returns the result. I have put this inside a 1 kHz timed loop with a commanded period of 1 ms and via the Ticks(ms) block and shift registers I calculate the amount of time per loop execution. This process is apparently taking 5 ms per cycle and to me that seems slow. Is that roughly the correct execution time for this kind of setup? I will attach my test .vi file.
What I'm using:
Windows 7
LabVIEW 2009 SP1
NI-cRIO 9024 with NI-RIO 3.4.0
Solved!

First off, the way you are doing timing isn't necessarily accurate because you don't know when the tick count VI is being called. For example, if it gets called on one iteration after your call library node executes, and the next iteration it gets called before the CLFN it executes, the subtraction doesn't include the call of the CLFN so you aren't seeing the true time it is taking for the dll to be called.
Where it says "error" on the top left hand corner of your loop. left click and choose previous iteration timing. Also, do you have the ability to choose a 1 Mhz clock? Are you sure it's actually being run on the RT and not on your PC? Running it on the PC would definitely make it difficult to execute at a 1 kHz rate.

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,
tutus

This is just an add-on to Satish's reply. You may want to chck this link to see how Profiler works,

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
Sarma.
