Program execution trace

Hi,
does exist any tool how to trace whole path a program was going through ?
Thank you.
Marian,

Hi Marian,
The best way to trace a program would be by looking at the call stack and the overview details in the debugging mode.If you want to analyse the performance of selects in the program then use the transaction ST05.If you are still not satisfied then run through the entire execution process by entering into the debugging mode.
The answers that you have recieved so far should be sufficient to close the thread.Please reward some points and kindly close the thread.
Cheers

Execution system differs between VI properties and Execution Trace Toolkit

I have a time critical acquisition VI whose execution system is set to "E/S d'instruments" (instrument IO). When I dump the execution trace in the execution trace toolkit it appears as "LabVIEW Thread [Standard]". Moreover there is a second line with the same thread name. Is this just a confusing bug or does it reflect a possible conflict in my program ?
Thanks in advance.
Gael.
Additionnal information : I am working on FP-2015.

Gael,
I made my top-level VI run at normal priority in the "same as caller" execution system, and my subVI run at time critical priority in the "instr I/O" execution system. The trace (attached) showed correct behavior.
There are a few things to try. First make a backup of your application. Try removing the storage management subVI assigned to "other 1". You should now have a top-level VI running at normal priority in the same as caller exec system and a subVI running at time-critical in the instr I/O exec system (same as my setup).
If you still get the weird behavior, we might be able to isolate the behavior to a subVI you're calling inside the time-critical VI. Try removing one subVI at a time and collect a tra
ce each time.
Alternatively, you can start with my simply VIs and slowly add components from your application until you see the weird behavior.
I should remark that when you assign a VI to run at time-critical priority, that VI gets its own thread, even if the VI is set to run in the "same as caller" execution system. So even if your time-critical VI is not adhering to its assigned execution system, it's still running in its own time-critical priority thread (shown as red in the trace tool).

Did anyone used Execution trace toolkit ??

Hi all!
I try to debug an RT application using Execution trace toolkit, and i wanted to tell everybody this tool is unuseable !!! It's impossible to debug anything with such a tool, and i wander how it's possible to even sell this tool !!! I have a 3.2Ghz with 1Gb RAM and this program takes 100% CPU during 2mn to refresh the screen !! Everytime you make a zoom, move the scrollbar... it takes more than 2mn !!!! And no : I didn't parameter a buffer of 5 000 000 (but 200 000, so approximatively 3ms of trace) !
So my questions are the following:
1) Does anyone have the same problem ?
2) Is there an other tool able to read a .log file ?
3) Is NI working on a better version for this tool ???
Thanks !

Hi KaBooOoom.
Though this is getting off topic; the issue with NI-CAN priority inversion was resolved by using multiple CAN cards. According to the developers at NI a two channel CAN card (I use the PXI-8464) has the same onboard embedded processor (386) and shared memory resources as a single channel card. Though the series2 cards were redesigned to improve throughput there are still some issues such as accessing the drivers from multiple threads.
I used the trace execution toolkit to identify the problem, but had to use internal resources within the NI-CAN group to find a resolution. Their proposal was to use multiple cards, and use only 1 channel on each. Yes; this can be an expensive proposal; particularly if you have to get a larger chassis as was my case. To get all of the cards working together "properly" (as their timebases are not sync'ed to RT); I had to use a pair of timers on a DAQ board which I happen to have in my system. DAQmx was used to route a shared clock across the RTSI backplane and also act as a synchronized time source for a few timed loops that I use to service CAN. You can PM me directly if you would like to discuss this further.
Thanks

NI RT execution trace toolkit and firewall

Hi,
I tried launching the RT execution trace toolkit and been ask to add the NI service locator to the exclusion list of my computer's firewall.
It appears that for LV 2010, the NI service locator is included within the SystemWebserver.exe located here:C:\Program Files\National Instruments\Shared\NI WebServer.
I added the SystemWebserver.exe in the exclusion list of the firewall but i still get the message asking to add the NI service locator to the exclusion list of my computer's firewall.
Any hint?
I'm Using Labview 2010 under Win7.
Regards,
Guillaume

Hi Guillaume,
So you have both the NI System Web Server, and the Real-Time Execution Trace Toolkit listed in the 'Allowed programs and features' section of the Windows Firewall control panel? Are they allowed on all network types?
If you ignore the firewall request, does the Real-Time Execution Trace Toolkit successfully connect to the target? If you turn off the firewall does the Real-Time Execution Trace Toolkit successfully connect at that time? Is your firewall managed by a group administrator?
Kind regards,

Virtual machine: Execution trace. HELP

HI,
I want to write an application using the latest jdk which shows a graphical representation of a program's execution. There are already commercial programs available I know but my one will be aimed at helping new programmers visualise method calls etc. helping debugging.
Is this possible? How does one log an execution trace, and know the variables, objects and method calls at a particular time in a program.
Any help would be very much appreciated. I need to know where to start! (And how!)

Tracing a java program execution

Hello. I would like to know which classes of a java archive (jar) are executed when i execute an application. Is there an easy utility to do this?
There's an application running on a server. I would like to know which class is called first when a tcp client is connection to the server...
Thank you for your help, it's very very important.

thank you. i thought that the java language had some specific modules to automatically trace a java program execution....
anyway, thank you.

How can I extract the data from a Real-time Execution Trace ".log" file?

I would like to get the data for the traces from the Real-time Execution Trace toolkit ".log" file to read in Excel and generate a report.

Hi Chuck,
Have you tried reading it into a text or binary file first and then generating a report using the Report Generation VIs?

Date format changes in the middle of a program execution

In my C code I have a series of select statements.
When I first get a session to the database I use the following command to set the date format
alter session set nls_date_format = 'MM/DD/YYYY HH24:MI:SS'
It works fine for a few queries. After a while during the program execution I see that the date format changes to 'DD-MON-YY' format. This results in a series of error in my code because I expect the date format to always be in the 'MM/DD/YYYY HH24:MI:SS' format.
Any idea why the date format should change all of a sudden in the middle of the program execution.

I second the idea that you should always use TO_DATE and TO_CHAR if you want to reliably convert between dates and strings.
Without seeing your code, it is hard to say why your date format is changing, but the most likely reason is that you are changing users somewhere in the code. For example:
SQL> show user
USER is "OPS$ORACLE"
SQL> SELECT sysdate FROM dual;
SYSDATE
11-JUL-2003
SQL> ALTER SESSION SET nls_date_format='dd-Mon-yyyy hh24:mi:ss';
Session altered.
SQL> SELECT sysdate FROM dual;
SYSDATE
11-Jul-2003 10:15:12
SQL> connect jtest/test
Connected.
SQL> SELECT sysdate FROM dual;
SYSDATE

Program execution during RIMODAC2..will it always reach to cif user exit

Hello ,
We are implementing cif user exit for Purchase Order at R3 side to capture additional date field. So logic to capture additional date field is put in user exit CIFPUR01. We have RIMODAC2 background job for Purchase order running on daily basis.
if there is no change in standard Purchase Order objects. When RIMODAC2 is executed for purchase order Integration models ..will program execution still always reach to R3 user exit part of the program irrespective of if any change in standard purchase order object has happened or not.
Will appreciate your answer.
Thank you
Best Regards
Nilesh Patil

Nilesh,
I am no longer sure I understand the question.
RIMODAC2 activates the model. Once a model is activated, if someone changes certain specific fields in an R/3 object, then these changes are sent to SCM, either immediately or via change pointers. All this happens irrespective of IM userexits.
If this same field in this same object is changed in R/3, and a userexit also has been implemented, the userexit will execute according to its design, performing whatever task it has been programmed to do.
If you create and implement a userexit, it begins working at that moment in time that it is installed. Data that flowed across 'yesterday' to SCM is not affected. Data that flows across 'tomorrow' will be affected. Data in R/3 will usually only flow across to SCM if there is some kind of triggering event, usually a database 'change' transaction (e.g., ME22N for POs) The mere act of installing a userexit will not generally affect existing data on either side. The userexit only affects data that flows across the IM. Unchanged records in the R/3 database will generally not be sent to SCM by the IM, and will not be subject to userexit processing.
It is not generally the responsibility of a functional consultant to explain the workings of a userexit to a technical consultant. It is enough that the functional identifies the userexit, and specifies the business requirement in as much detail as possible. The developer is then responsible for carrying out the coding. Technicals are generally expected to be competent enough to determine from the userexit docs, and from the surrounding code, how a userexit works. They can also raise a message to SAP. In the end, it is all just ABAP, although userexit implementations can be quite challenging. SAP seldom provides enough details in their documentation. Once the Technical has finalized the code, Functional and Technical together then perform unit testing, before passing the mods to users for integration testing.
If your client's coders are unable to manage the task, perhaps they should engage your company to provide technical expertise, as well as functional expertise.

Remote Program Execution

Dear Sir,
I have following problem and very desperately looking for the solution .
I have 9ias installed on window-2000 server and on this machine JSP/Servlet is also running .
There is another Unix server also having Oracle 7.3.4 and Pro*C installed .
My requirement is that on receiving a web client request , the invoked JSP must also execute a C program on the unix machine ( the execution of C program creates a text output file on the unix machine ) and after completion of C program execution the output text file must be available to JSP . As a final result of JSP execution this output text file must be returned to WEB Client .
Please guide me how to go about this .
Thanks and Regards
B V Mittal

Call your C program like this from your controller servlet
Process p = Runtime.getRuntime().exec("c.exe");
BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
Then read from your generated file and populate whatever you need into a bean.

How to use Real time execution trace toolkit with Dual-core processor??

hi there
the situation as follows:
i have a computer (PC and Laptop) types with Dual-core processors, and am trying to do simulation using Multi-core technology and based on different simulation scenarios...starting from sequantial processing,.......Piple lining processing strategy. so that i can differentiate the time delay between those types of processing based on (Using 1 processor then dual-core processor Computers)
my question is: As i read through Ni's white papers i saw many notes refer to Real-time execution trace toolkit to investigate the (processing-time , etc) of multi-core processors in processing diffenent algorithms. My algorithms are to be run on 1 computer with dual-core processor BUT, not in real time environments, that is ( No hardware to be connected to my pc) only algorithms running on my pc....
So, is it possible to use Real time execution trace toolkit or anyother tools in LabVIEW to show processing-delays and/or anyother timing critical issues without using my application for real- time hardware.???
in other words: how to use Real time execution trace toolkit in non-hardware and/or real-time scenarios???
please help me in this.
Any suggestion, comments, feedback.....is absolutely highly appreciated
thanks a lot in advance
Labview Lover

Hey,
The Realtime Execution Trace Toolkit only works for NI RT Targets.
But you can use the Desktop Execution Trace Toolkit, just search for it under ni.com.

How do I pinpoint the program execution?

Hi all,
I am wondering how to pinpoint the program's execution point? I have a problem with all of the loops not stopping properly. I hit the "Hilight Program execution" and it went to one loop, that is, it appeared greyed out, but I can't figure out which case it's stuck in. Is there a way to find the exact *point* of execution?
Thanks,
Jason

You can use breakpoints. The program will pause as soon as it hit the breakpoint. To add breakpoints, right-click in the place where you want it and set it. You can also set probes. The probes activate as soon as the information is available. Then you can be creative with the highlight execution, breakpoints and probes. You can have a fairly good idea on how your program is executing.
Otherwise, try posting your code or an image of your code so we can try to figure out what is going on.

Execution trace won't transfer trace to host

I am trying to get the execution trace toolkit to work on my system for the first time. I am using a PXI-8196 realtime controller. I have put a TraqceTool Start on my block diagram for the real time system as well as a TraceTool Stop Trace and Send. I have the Execution Trace Tool running on the host computer. When the real time code gets to the TraceTool Stop Trace and Send vi it gets stuck and eventually gives the error "Error 56 occured at TCP Open Connection in TraceTool Stop Trace And Send.vi->test_main_delete.vi. Possible reason: The network operation exceeded the user-specified or system time limit.". I am using the company network in which the IP address is set up to obtain an IP address automatically but, I have gone to a command window on the host machine, typed in ipconfig and taken the IP address that specifies and have attached that IP Address to theTrace Host Network Address connection on the TraceTool Stop Trace and Send vi. I'm guessing it has to do with the IP address I have inserted but, I can't figure out any other way to talk over the network to the host machine. Any ideas??

Hello,
The IP address returned by ipconfig should be perfectly valid for the Stop Trace and Send VI, so long as you don't restart your host PC or obtain a new IP for the host. One thing to verify as well is whether you have multiple internet adapters (for example, an ethernet port and a wireless card), since each of these will have separate IP addresses. Additionally, this VI will attempt to communicate with your PC over a particular port, if you have a firewall enabled, this port is likely being blocked. Try running it with your firewall disabled.
If all else fails, you always have the option to save the trace log file locally on the RT target and retrieve it later via a standard FTP connection. To do this, use the Stop Trace and Save VI instead. Give these a try and let me know how it goes.
