Overflow memory desktop trace execution toolkit
I tried to debug a few leaks of possible memory with running office toolkit. And you know - the Toolbox crashes because it records events too! It seems not to be possible to get it to connect to the file, or to do anything else.
Apart from the taste of the irony that the Toolbox which is supposed to track memory leaks has't had this kind of protection - someone has managed to find a way around this?
(I know it's a problem of long duration with this tool kit - see http://forums.ni.com/t5/LabVIEW-Idea-Exchange/Improvements-to-the-Desktop-Execution-Trace-Toolkit/id... )
I'm sorry you're having trouble with the Toolkit of Trace Desktop performance.
What version of the DETT do you currently have? Make sure you use the latest version because there was a lot of changes on the different version released.
I noticed on the other post on the forum that you could change the number of events that it caps to. did you tried to change this setting? :
"The current implementation preserves all traces in the memory to keep possible fast pace of generated events. There is a setting in the TraceTool.ini (MaxEvents = 4000000) file that specifies when the tool stops tracing because of too many traces. »

I'm trying to save data from 4 ports to 40.96 Mhz. using a producer consumer architecture and a PCIe NI 6527 B using an external clock.
I inherited code which works for 2 ports. I tried to add additional ports and changed the size of the data to the DAQ.mx queue and data. Launch the program several times, reach conflicting error messages after less than 2 seconds from the beginning:
Error 200284: Some or all of the requested samples are not yet acquired. [...] To make available samples more quickly, increase your sampling rate
200361 error: Overflow memory device on board. Due to the limitations of system and/or the bandwidth of the bus, the driver could not read the device fast enough to follow the flow of the unit. Reduce your sampling rate.
What is a race condition between the error messages, a problem of timing of start or something else?
I approach, how to debug these types of problems? How can I determine what is causing the error? I can't single step through because I'm at the wheel of sampling with an external clock.
Running on labview 2012 Windows XP on the machine who's 3.17 GB of ram.
Try to reduce the size of your buffer. In fact, simply leave the calendar DAQmx unwired. The size of the buffer must be large enough by default. And then also try to read less data at a time, as data instead of data 500ms 10ms. What I suspect here, it's that the DAQmx buffer is too large and therefore must use the hard drive for part of the buffer, to slow things down a lot.
Other notes here:
1. do not use the time-out to stop your loop of consumer. Your producer should send an order of a certain type to your consumption by telling it to stop. In this case, I would use an empty array. And then, you must release the queue after the loop of the consumer.
2. you want a constant FALSE to Append Array/String input size of the binary file write. This will remove the 2 I32s at the beginning of each table that you write. Eelle are here to tell the size of the table being written. But since you are just data flow, I doubt that you care about those.
3. instead of the entire setup of producer/consumer, have you considered using just the DAQmx Configure Logging VI do DAQmx stream directly to a TDMS file for you? Makes things much faster and much easier on you.
Hi, I have worked with labview for the past month with the material
and the software.
I was wondering if there is a way to see the order of
execution of the vi... It would be nice to see on the block diagram has
system of reheating or dialing device or stream that indicates the order of the drop-down list
operation... I think that all this is done behind the scenes of labview... He could
be nice to have a trace or a label... perhaps that it exists... I'm getting
the book scientists and engineers... then maybe it's there... any help...
A simple programs is not a problem... I've seen some complex vi!
I guess I'm allows the old C programming... line by line...
Perhaps with time?
I have a lot of things to think about, this case is solved...
Thanks for any thoughts here...
HELP if I can put this pny optima md4096sd3-1333 Fund memory module - 4 GB pc3-10666 ddr3 1333 mhz hp pavilion model fq515aa-aba agg20f PC with windows vista
Hello Q -.
I understand that you're looking to see if you can install DDR3 1333 mhz RAM memory in your HP Pavilion a6620f desktop PC. According to the HP Pavilion a6620f Desktop PC product specifications page, your computer uses DDR2 RAM NO, you cannot use DDR3 RAM in your computer, it will not work and may possibly cause damage.
I hope that I have answered your question to your satisfaction. Thanks for posting on the HP Forums. Have a great day!
I have a Compac Presario with a motherboard M2N68-(Narra6)... I know it can withstand PC3-10600 ram for memory upgrade... but I can't find out how much ram I can actually go to... I have currently 3GB I would have at least 6 GB...
My operating system is Windows 7-64 bit
Checked with Geeks at Staples and they aren't really sure... someone can tell me if I can go to 6 GB and it will work?
I looked at the motherboard plug, and they say that the Board can support a maximum of 4 GB of memory (2 x 2 GB).
I guess if there were two additional locations as there were up to, while he could have executed 4 x 2 GB of PC3-10600 memory.
You can always run the free memory Crucial analysis tool and see what it reports as well.
Hi any idea how to read or check use all memory space by accumulating the table with the data?
My program works like this: -.
(1) values are acquired and displayed on the table
(2) the values are acquireduring the next event and appear in the next row in the table.
(3) and this continues...
Thanks in advance
You can use 'Flatten channel' to get the size of your data.
There, I think of the stack trace that is done automatically on all running applications when "something goes wrong.
I have an application that freezes up (I suspect it is a blocking of the thread) and it would be great to have a practical method to force the stack trace in the event of phones log. (The phone still works ok, it's just the single application that froze).
Unfortunately the user having the problem that's about 3 000 mi away from me, so I can just plug in the phone and use the option 'connect to the device.
Update: I guess I could always send to the user another app... one who deliberately misbehaves...
You can trigger a stack trace by launching a Throwable. You can take in your application so that the user sees no error dialog box.
I have a question about windows server 2008 R2 that is about a year. After installation, it worked effectively for a few months, then it starts to freeze showing a message "insufficient system resources exist to complete the requested service". Previously, he started once or twice a month, now it starts to get serious. It's freezing systems, you need to restart the server using the power button / stop. Can it's disturbing for me, someone help me. Thank you in advance.This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)
Hello everyone, this is my first post here, I hope it's in the right place :-)
I was making mistakes of memory. I am running LV 32-bit on a system with 24 GB of memory. I understand that LV may use only 2 GB of memory, even if I used the utility followed memory to trace a problem at one of my Subvi, in which I use a functional global to store arrays of data.
My LV program periodically takes in an array of new data. Whenever a new data table is received, I divided into its constituent parts and store these components in another series of paintings. I use the USR to store the functional arrays as globals, since I heard that this tactic will improve performance. However, using the utility followed memory, I find that the Subvi takes much more memory than indicated the amount of data stored. So, I guess the Subvi has made multiple copies of data than expected.
Could you please take a look at this VI someone and tell me what "rule" I am breaking what problems? It is not too big, I think we should that the eyes of an expert. I'm still a little new to LV :-)
How much data are you trying to store in this functional overall? How often is it updated, and how many times it is called between resets? If you know the maximum size of the data you need to store, it may be better to have the case reset allocate arrays of this size (instead of empty tables) and then maintain an index indicating both the current size of the table and the position to insert the next piece of data. It will be more effective than to build the table.
Now, even if you have enough memory to store all the data, it can be too fragmented to be usable. Whenever you use array of generation in the loop, LabVIEW will allocate a new array of the current size of + 1 and then copy data to it, after which it can make memory of the former small table available again. The next time the loop for this once again, setting up small blocks of memory available which may not be contiguous and are too small for reuse when the berries then need to grow. Pre-allocating berries to the maximum size and then replace the items one at a time (as new data arrives) will solve this problem. In addition, it will be faster, because it takes less time to replace one does it to copy all of a table to a new location.
In addition, there is no need of the loop for use replace table subset. Delete the register shift and let the autoindexing to build the output array. You actually produce an extra copy useless trying to reuse the table, instead of save memory (because there is a copy in the shift register and the other being used for autoindexing). For loops are effective for the construction of the tables because their maximum size is known before the loop begins. In addition, the table to initialize is unnecessary - you are initializing the values that will be immediately be replaced - and you don't even have the function of the size of the array. I'd do it as shown below:
would the G.SKILL Ripjaws Series 8 GB (2 x 4 GB) 240 - Pin DDR3 SDRAM DDR3 1600 (PC3 12800) model memory desktop F3-12800CL9D-8GBRL be compatible with my computer? If no, what type of ram should I get (as this case latency time and how fast)? is also SO-DIMM compatible?
Please try the following RAM for the HP 2000 series:
They guarantee the work of RAM.
Hi is there any tool I can install or use with SDK native to see the memory consumption during execution on the device of my project? Thank you.
Sure. You need to open the System QNX perspective information (window > Open Perspective > QNX system Perspective). From there, you should be able to view the memory usage of your application via the tabs System summary, the memory information and the Information of Malloc .
I installed a 11 GR 2 Oracle RAC (22.214.171.124) database, but I see the use of the feature of running parallel SQL queries, but I never used that.
I would like to know if this feature is enabled by default on CCR environments and if it does not require me to pay for Enterprise Edition.

You are not, but Oracle is, since you are using RAC. Oracle relies on execution in parallel against the gv$ views so even if you can't use it in SE way common Oracle can when it comes to query against one of the points of view gv$. That's why DBA_FEATURE_USAGE_STATISTICS reports that you see.

Whenever we start a request will start a process called ESSVR.exe in the background and his memory, consumption will increase as and when we run the calculations. But after the calculation is performed should not reduce the memory consumption.
Whats happening is that sometimes the calculation gets hanged and when I kill the process and start it again, it is run after a couple of times the calculation again gets hung, is possible to free this memory consumed by the process through calc only, script commands so that every time when a calc script finish the memory is released. We use essbase 9.3.1.
When an application is started, the first thing it does is enter memory equal to what is defined as the key cache. This memory is never released until the application is stopped. He leaves also consumes memory for the data cache as she needs until he reached what is defined for this cache. Yet once that memory is not released until the termination of the application. In addition, additional memory can be consumed for different things while the demand is increasing. For example dynamic cache calculator will use memory during the execution of a calc, each user to make recovery uses a little memory (which can add up with many users). ASO data load buffers use memory, kinds of report and recoveries, etc., you get the picture. All these resources are released when the application terminates. (or should be, there have been cases of memory leak in some versions)
Ive read that you can set < CFQUERY name = "session.queryname" > to cache the set of records. Im confused about how it works. Replace the memory usage a query would use if she was appointed without the "session." This caching? Or if she puts the record set in memory in the form of scans?
I hope that makes sense. We receive a 500 error message trying to run the model. We have reduced to my page as well as others that are running at the same time that also receive the error message. Anyway, we are looking for a way to free memory during the execution of our models. If anyone has any ideas on this it will be appreciated.

To pretend that it's a lot... So regardless of the amount of data and the memory that is used, is far from reducing the amount of memory used?
The best way is to reduce the amount of data returned to Cold Fusion. Ways to do this are:
Select only the fields you need.
Select only the records you need
Prune the characters of the fields.
Given the way in which you said that you collect your data, some of these methods are not placed at your disposal.
