How to find the elapsed time between 2 events ?
I want to use the robot class and I have register all events in a file but when I use the Robot. It isn't synchronous. So I should find th elapsed time between two events for reproducing them with the method delay of the class Robot.
Thanks
It sounds like you want to reproduce the events with varying time between the events? This is a good idea for a couple of reasons 1) it's possible to enqueue events so quickly that Robot gets ahead of the Java GUI, and 2) every human does their mouse/keyboard activity at varying (and relatively slow, relative to the computer that is) rates of speed. It would help make a more realistic interaction to vary the speed of event reproduction.
Since you can't control the amount of time between the call to Robot and when the event arrives in the application, you can't be ultimately precise about this. You'll have to accept a teensy bit of slop in the process and just live with it.
That is ... you can do something like robot.method1() .. Thread.sleep(1) .. robot.method2() .. Thread.sleep(1) ... and that will give slight delays. If you vary the value for Thread.sleep you can vary the event reproduction speed. Early in the development of Robot I experimented with something like this - I set up an EventQueue listener to capture all mouse/keyboard events (remember that each comes with a timestamp) and then reproduced events using the time intervals from the captured events to control the Thread.sleep times between Robot calls. It worked pretty well, and the mouse would dance around in the same way I moved the mouse around.

When my process stops, I am reading an array of tags(datapoints) and writing the max and average to memory tags for data logging. However, when viewing the data, the elapsed time between cycles spreads the data out unevenly. It could be 90 seconds between cycles or maybe two hours or longer. Is there a way to convert the time axis data to be just consecutive datapoints?? It would be like logging data based on a particular condition happening rather than time-based trending. Should I try to use the data set logger examples instead?? I would prefer to use the built-in datalogging features rather than writing to databases.
You could export your data to a spreadsheet file and then actually write then again in a second database using this example program in the devzone
http://zone.ni.com/devzone/conceptd.nsf/webmain/5A921A403438390F86256B9700809A53?opendocument
Using this program (if you don't want to modify it, which would take a reasonable amount of time specially if you are not familiar with VI-Based Server) You would have to generate a collum in your spreadsheet file to be the timestamp, it would be a artificial timestamp.
What you could do in your application is to first save the data to file and then read from file, substitute the collum timestamp for the "artificial one" and then write it to the database, again, with that you would not need to modify this program.
However if you have the time and is willing to work with VI-based server you could try to modify the example program to be adapted for your purposes.
I hope it helps
Good Luck

FROM all_tab_columns
WHERE table_name = 'TABLE_A'

I was also looking from a DBA point of view, say increasing the DB_CACHE_SIZE from 5GB to 8GB as the machine has almost 32GB memory out of which 13GB is free memory. Because the timed event is "db file sequential read" which takes 95% of Total Call time.

How to find the execution time
Hi
I don't know whether it is possible in Oracle or not?
Say i have got around 20 odd Views in my DB and couple of them based on Materialized View which is again created by joining more than 5 based tables.
Even most of the Views are also created by joining base tables and MV's.
When i execute Select count(*) from <viewname>;
I do get the count of rows and on avg each view returns more that 30lacs row.
And when i excute select * from <View_name> by setting the Time on.
It takes more than 2 hours to return the rows.I know the elapsed time of a query do depend of external factors as well such as number of users using the DB Object used in thoe views,Number of process involved and all.
And therefore in order to gather the elapsed time of each and every view will take more than a week .
I would appreciate if anyone can provide me a better approach or even a shell script or something like that which will give me the elapsed time of all the views if i query (Select * from <view_name>);
Thanks in advance.
VineetBut to SomeoneElse's point, if you are running
SELECT * FROM view_namefrom SQL*Plus, what you are primarily measuring is how fast your network is (because you're spending a great deal of time sending data from the database to the client) and the speed of the SQL*Plus client on your machine (which has to fetch that data, which may have to format and display that data, etc.) It is not a particularly meaningful metric. If you tuned the client machine so that SQL*Plus wasn't displaying the data, if you increased the fetch size, etc. you could drastically decrease the time it would take to send all the data to your client machine, but that is probably not going to constitute tuning for anyone other than you (i.e. you might see a halving of run time while everyone else saw no change).
Beyond that, doing a SELECT * with no criteria is likely to involve execution plans that no one else will see, data access patterns no one else will see, etc. which just makes the benchmark you are proposing irrelevent.
If you really, really want to measure how quickly your client can pull the data from all the views, you could of course let that run for a week. But the number wouldn't mean anything.

[How-to] Find the middle point between sides of two distant objects.
[In reference to my attachment]
I would like to find the middle point between object A's right-most segment (in green) and object B's left-most segment (in blue), quickly, effectively and reliably.
Ideally, there's a function i'm not familiar with that exists . I would rather not resort to having to create more objects to "figure out" the middle point manually, so-to speak.Dandreu,
In a more general case than assumed in the first post, if you wish to have an actual key point, you may:
1) Direct Select each of the path segments in question and Ctrl/Cmd+C+F+X+F,
2) Select either and rotate it by 180 degrees,
3) Object>Blend>Blend Options, with 1 Step, then Object>Blend>Make, then Object>Blend>Expand,
4) Select the line in the middle and Object>Path>Add Anchor Point.
You may also do a similar way where you add an Anchor Point at the middle of the segments and ClickDrag with the Line Segment Tool between them, but that is a bit destructive. -
How to find the execution time of a query?
hi guys,
i need to find the execution time of a query.
i tried finding it in rsrt but couldn find the execution time.
pleasse let me know the way to do it..

sagarHi sagar,
If you want to know the frontend time, first of all you need to maitain the BW Statistics. To maintain you have to go the respective target and click on it. Go to the tools, select BW Statistics of infoprovider. It pop ups a window there you find two check boxes 1) WHM and 2) Front end time. Check both.
Now Exe query and close the analyzer. Then go to SE11 table RSDDSTAT. There is one field which displays Frentend time.
OR
Go to STO3 here also you can analys the frontend time.
If you feel useful Assign Pts.

How to display the elapsed time of a video (event video) in Captivate 6
I have a Captivate 6 project which includes two separate videos and I am wondering how I can display an elapsed time for the videos - preferably one that stops if the individual stops the video.
Hello and welcome to the forum,
Are you talking about an inserted video, or about the Captivate file itself? I'm asking this because a lot of users refer to a published CP-file as a video.
'Elapsed time': is this the real time spent by the user, or the time as you can see in the TOC (developer's time)? I blogged once about the difference.

preetyHello Preety,
Goto RSRT give the query name and see the technical property you will find the query generation time.
For the time taken for execution Select the execute and debug mode in the options select display statistics.

How to find the transport time?
Dear all,
Our inbound delivery document's delivery date calculation = Actual GI date in Outbound Delivery + transport time.
My question how do i find out the transport time? where in the outbound dlivery document state this and where in the SPRO stated the outbound dlivery time?
thanks
TuffSAP online help:
The route determines the means of transport and the legs involved. It influences transportation scheduling. For example, the system can determine from the route that goods are to be sent by rail to Boston. Therefore, during transportation scheduling, it takes into account how far in advance loading space in the freight car must be reserved.
http://help.sap.com/saphelp_erp60_sp/helpdata/en/dd/5607da545a11d1a7020000e829fd11/frameset.htm
LIKP-ROUTE is the route assigned to the delivery, it is not time. As you can see route has an impact on scheduling but it is only one factor.
Please read SAP online help about delivery scheduling:
http://help.sap.com/erp2005_ehp_05/helpdata/EN/dd/5607e7545a11d1a7020000e829fd11/frameset.htm.
I think it's better you take your time and and invest some energy in reading the help, there's no point in writing down the same again on the forum.
In customizing you can go into the definition of the route and check the help for customizing node as well as F1 help for the route-fields.

How to find the Response time for a particular Transaction
Hello Experts,
Am implementing a BAdI to achieve some customer enhancement for XD01 Transaction . I need to confirm to customer that after the implementation and before implementation what is the response time of the system
Response time BEFORE BAdI Implementation
Response time AFTER BAdI Implementation
Where can i get this.
Help me in this regard
Best Regards
SRiNiHello,
Within STAD, enter the time range that the user was executing the transaction within as well as the user name. The time field indicates the time when the transaction would have ended. STAD adds some extra time on using your time interval. Depending on how long the transaction ran, you can set the length you want it to display. This means that if it is set to 10, STAD will display statistical records from transactions that ended within that 10 minute period.
The selection screen also gives you a few options for display mode.
- Show all statistic records, sorted by star
This shows you all of the transaction steps, but they are not grouped in any way.
-Show all records, grouped by business transaction
This shows the transaction steps grouped by transaction ID (shown in the record as Trans. ID). The times are not cumulative. They are the times for each individual step.
-Show Business Transaction Tots
This shows the transaction steps grouped by transaction ID. However, instead of just listing them you can drill from the top level down. The top level will show you the overall response time, and as you drill down, you can get to the overall response time.
Note that you also need to add the user into the selection criteria. Everything else you can leave alone in this case.
Once you have the records displayed, you can double click them to get a detailed record. This will show you the following:
- Breakdown of response time (wait for work process, processing time, load time, generating time, roll time, DB time, enqueue time). This makes STAD a great place to start for performance analysis as you will then know whether you will need to look at SQL, processing, or any other component of response time first.
- Stats on the data selected within the execution
- Memory utilization of the transaction
- RFCs executed (including the calling time and remote execution time - very useful with performance analysis of interfaces)
- Much more.
As this chain of comments has previously indicated, you are best off using STAD if you want an accurate indication of response time. The ST12 (combines SE30 ABAP trace and ST05 SQL trace) trace times are less accurate that the values you get from ST12. I am not discounting the value of ST12 by any means. This is a very powerful tool to help you tune your transactions.
I hope this information is helpful!
