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

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.

Measure plsql execution time

Hello dear teachers,
i would be gratful for advice.
I have materialized view that is refreshed with the dbms_mview procedure and it's scheduled through dbms_job.
How could i measure that refresh execution time so i can for example query one table and have in there when this job(refreshing) started , and when did it finish ?
I could do set timing on in sqlplus , but is there somthing like that in plsql and than insert that time in some table ?
i am on 9.2.0.7.

set serverout on
declare
start_time number;
elapsed number;
begin
select to_char(sysdate,'sssss') into start_time from dual;
-- put here your code
select to_char(sysdate,'sssss')-start_time into elapsed from dual;
dbms_output.put_line ('Elapsed='||elapsed);
end;
/You can use systimestamp to get a more precise result.

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

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.

How to measure fpga execution time

Howdy--
I'm hacking through my first FPGA project without yet having the hardware on hand, and I find I could answer a lot of my own questions if I could predict what the execution time (ticks, mSec, whatever) of bits of my code will be. Running FPGA VIs on the Dev Computer with built in tick counters does not seem to be the proper way to go. Is it possible to know the execution time of FPGA code before compiling and running it on the target?
If it matters to anyone, my context for the question is a situation where a 10 uSec loop is imposed by the sample time of my hardware (cRIO 9076, with a couple of 100 ks/S I/O cards), and I'm trying to figure out how much signal processing I can afford between samples.
Thanks everyone, and have a great day.

bcro,
You can look into cycle accurate simulation, which would give you a better understanding of how your code will work. More information can be found here: http://zone.ni.com/devzone/cda/tut/p/id/12917
As a rough measure, you can estimate that simple functions will take one tick to execute. However, there is not list of what is and is not a simple function.
You could also try placing code inside a single cycle timed loop (SCTL), which would then guarantee that all of the code in the loop will execute in 1 tick. However, if you are doing a lot of operations or trying to acquire an analog input, this will fail compilation.

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.

Measure command execution time

How can we measure that how much time has been taken by a command to complete. For instance if i 'm running a find / -name something ..
how can i find out for much time did this command run.

Try the time command. See man time.

Procedure/Function execution time

Execution time of a flat-sequence

Hello there -
Is there any way to get a measurement of how long each part of
the flat sequence takes to execute? Anything like matlab's "tic" and "toc"
commands in labview? I have been playing with it for a while now and
have yet to discover if Labview has this functionality. Anyone know of
anything like this?
I currently have a VI that controls the realtime acquisition of a CCD camera via Firewire and a USB spectrometer. The VI collects data from each of these devices (triggered by an external source at 10Hz), and dumps them into a Matlab script which does analysis on the CCD image and spectrum. The bulk of the VI sits inside a while loop, which continues to run until the user presses the stop button. Inside this main loop is a flat-sequence. The sequence goes: ACQUIRE DATA ---> PROCESSING DATA ----> MATLAB SCRIPT ----> PLOTTING GRAPHS -----> OUTPUT DATA TO FILE.
The problem here is that the VI runs at 5Hz, while we are triggering it at 10Hz. Originally, it was my thought thought that the matlab algorithm was to blame, but I used the matlab commands "tic" and "toc" to determine that the matlab algorithm runs in 15-20ms. I did this by putting a "tic" command at the top of the matlab algorithm and a "toc" command at the bottom. The problem, as I have now discovered is that the rest of the labview code takes ~180ms to execute. (This was discovered by putting the "tic" at the bottom of the program, and the "toc" at the top of the program, thereby measuring the execution time of everything except the matlab algorithm). Each time a trigger signal from the external source comes in, it starts the flat-sequence structure (which takes ~190ms), and then waits for another trigger signal, always missing every second signal. My eventual goal is to reduce the bloat, and get the algorithm down to less than 100ms, so that I can run the VI and acquire data at 10Hz rather than 5Hz. If anyone can offer some help with this, it would be much appreciated!
Eric
P.S. - I have attached a copy of the VI that I am working on, but unfortunately, it most likely will not run on your computer....the VI will not run unless it is connected to a triggered spectrometer and CCD camera....but I have attached it anyways incase anyone who can help might want to take a look.

can we divide the program into 2 parts and use background process for acquisition and front end process for analysis?
I mean, create 2 VIs from the present VI and then launch the acquisition program dynamically as a background process and fire events in Main VI from acquisition VI and process it. not sure how much it is going to reduce. lets give a try....

Execution time continues to increase while vi is running

I started with a vi which reads data from a WII remote (wiimote). The code works. I want to convert the acceleration data to velocity and displacement by numerical integration. Accurate conversion requires a measure of execution time. The vi correctly returns 9-11 ms when it first starts, however the measured intervals continue to increase in lenght as the vi runs. The measured interval goes from 10 ms to 80 ms after about 1 hour. I used a tick counter to measure the loop execution time. Any suggestions?

Can you do some profiling to see which subVI could be the problem?
If you look at the task manager, how is the momery use over time?
Your timing systems seems flawed, because the execution of the first tick cound is poorly defined with respect to the rest of the code.
Some typical things to look out for.

Execution time too low

I was trying to measure the execution time. The rate is 1KS/s per channel and the samples to read is 100 per channel in a for loop of 10. The time should be around 1000ms, but it's only 500-600ms. And when I changed the rate/numbers of samples, the execution time doesn't change..... how could this happen?

You can right-click on the output tunnel and tell it to not auto index. But even better would be to use shift registers just in case you tell that FOR loop to run 0 times.

LabVIEW2012 has long execution time to write string than LabVIEW2011 on XP SP3

in for loop, each execution will output string and display it on front panel by value property.
But after upgrade to LabVIEW 2012, the execution time doubled on Chinese XP OS, I really want to know this difference between LabVIEW 2011 & LabVIEW 2012, pls advice.
"I think therefore I am"

This is no way to measure the execution time. Your parallel while loop spins as fast as the computer allows, consuming all CPU it can get in the process, and starving everything else. Your code is highly flawed!
Eli: actually I add 10milliseconds delay inside both for and while loop.
In addition, get date/time in seconds is also a relatively expensive function, not to mention all these local variables! Your benchmark is completely meaningless! All it does is slow down your regular code, nothing else. How do you know in what order things start? Where is the "start time" initilized (where is the terminal?!)
Eli: I am using the states machine, and set the "start time" during the program initialization, then calculate "test time"in next case (running block).
A proper benchmark uses a three-frame flat sequence with to high resolution relative seconds timers, on in each outer frame and the code to be benchmarked in the inner frame. (here is an example). The difference between the two timers is the exection time of the inner code in seconds. Make sure to only have wires in the benchmarking code. All controls and indicators belong outside the sequence. Also make sure that no other code can run in parallel to the sequence.
Use this and you'll be surprise how fast your code actually runs.
Then you should also disabele debugging.
Please attach your actual code (including the subVI) so we can see what else you are doing wrong.
Eli: if possible, give me your mail address, then I can sent more actual code to you separately.

OSB: reporting via service callout & reporting execution times

Assume I made a common local service for a general report action and it's called from all inbound proxy services. At the moment all I see is in the report database is: inbound service uri: LocalProxy and inbound service name: <my local report service name>. How can I log the original service instead which was called?
An other question: is it possible to report the execution time of the service call into the database as well? I'd prefer having two measures: service execution time from the inbound proxy service until it leaves the ESB with the response; and the called business service execution time.

What to do if data grows heavily.How to decrease the execution time

Procedure execution time increases from 1 minute to 40 minutes in the past three years. I think this is due to increase in size of tables. We are maintaining the database from last 6years. Nearly 25,000 records are adding per month in a table. Now each contains above 12Lakh records. I already used Query Optimization techniques. So please suggest me what to do.

So, does this process need to access the whole table or is it just interested in the last months records?
I already used Query Optimization techniques.meaning what precisely???
So please suggest me what to do.Without knowing a whole bunch more about your situation we cannot give you a solution. You have one slow process. So what? For instance, let's presume this is a batch process that runs once a month. Does a forty minute elapsed time matter compare to processes that are used by all your users many times every day? Are you prepared to risk the performance of those OLTP functions to improve the runtime of that batch process?
