Help with maxage / limiting the use of the default recording disc

I have 2 related questions:

(1) is it possible using the - XX: StartFlightRecording and/or XX:FlightRecorderOptions causes of flight recording to keep only last minute value of N to the details on disk, so that everything no matter how much one can view data about the last minutes worth of activity N?  How?

2), which is the maxage parameter supposed to effect?  Reading http://docs.oracle.com/javase/7/docs/technotes/tools/solaris/java.html it seems that it is supposed to do the above, but I couldn't see any difference in behavior with any of these args, and in particular, each of them continues fill ed. / tmp with .jfc files well beyond the limit of maxage.

No maxage:-XX: + UnlockCommercialFeatures - XX: + FlightRecorder - XX: FlightRecorderOptions = defaultrecording = false, dumponexit = true, dumponexitpath = / tmp, loglevel = trace

Maxage on StartFlightRecording:-XX: + UnlockCommercialFeatures - XX: + FlightRecorder - XX: StartFlightRecording =maxage = 1 m - XX: FlightRecorderOptions = defaultrecording = false dumponexit = true, dumponexitpath = / tmp, loglevel = trace

Maxage on FlightRecorderOptions:-XX: + UnlockCommercialFeatures - XX: + FlightRecorder - XX: FlightRecorderOptions = defaultrecording = false dumponexit = true, dumponexitpath = / tmp, loglevel = trace,maxage = 1 m

THX,

Chris

(1) Yes, by using the maxage parameter. But it only works if drive = true, if you have a repository of disk, if you do not specify maxage/maxsize and defined only disk = true, the JVM will set default values, if you use defaultrecording = true. If you want infinite, set maxsize = 0, maxage = 0 to override the defaults.

(2) the maxage/maxsize parameters thresholds at which the JVM will begin to remove the registration from the repository of the disc. Because it would be costly check each written event thresholds, thresholds are checked only when a new piece of record is created, which is on each 12-15 Mb (depending on how much the data exist in thread pads when they are empty) so with a short maxage, like 1 minute, he may not have sufficient data to trigger the removal of pieces.

  • set the default recording time in windows sound recorder

    Looking for a way to increase the default value to the recording of the sounds found in XP home recorder.  There is no documentation that I can find to the configuration

    Hello

    In the default recorder recording time is 60 seconds. There is a solution to increase the maximum recording time. Follow the steps mentioned below:

    Step 1:
    a. utility start Sound recorder.
    b. click on save and then Sound Recorder run for 60 seconds.
    c. once the sound recorder to stop recording, click Save as on the file menu, and name the file Blank.wav.
    d. in order to increase the maximum duration of recording in sound recorder, click Insert a file in the Edit menu, and then insert the Blank.wav file saved in step 3. When you do this,
    the maximum recording time is increased by 60 seconds. You can repeat this step once for each additional minute recording that you want to add. For example, for 5 minutes
    recording time, insert the Blank.wav file five times.

    Step 2:
    To make the tape recorder automatically use the extended length of the recording time:
    a. Click Start and then click Open.
    b. double-click the programs folder.
    c. double-click the Accessories folder.
    d. double-click the multimedia file or entertainment.
    e. right - click sound recorder and then click Properties.
    f. click on the shortcut tab.
    g. in the target box, press END, press the SPACEBAR and type the location of the file Blank.wav.

    For example, if the target is 'C:\Windows\sndrec32.exe', and the location of the Blank.wav file isC:\Blank.wav, the new line in the target box is "C:\Windows\sndrec32.exe C:\Blank.wav"

    The next time that you start the tape recorder, the Blank.wav file opens automatically. After you save your new .wav file, you can click on remove after the current Position in the Edit menu for
    Remove the extra space in the file.

    NOTE: when you have finished recording and editing of your new .wav file, save the file with a new file name.

  • Help with fft vibrations without using the package of noise and vibrations

    I'm looking for help in the analysis of vibrations. I use an example updated NI 9233 VI, to get a signal from the accelerometer for display using a FFT power spectrum. I'm not entirely sure if it works, because it's the first time I've ever done vibration analysis on LabView. So if you could explain a thing or two about vibrations or TFF, I'd be more than willing to hear from you. I have included my code along with a photo of an analysis of vibration of the computer, I work with. (even when I don't know if his work that I just thought it would be good to show an output)

    Brandon

    Data sheet:

    I have LabView 2011

    I FPGA, real-time

    I have a model of research of Wilcoxon accelerometer 797-33

    With an NI 9233

    On a cRio-9012

    Hi Brandon,.

    You can use the FFT Complex (photo attached) to calculate the magnitude of the acceleration at different frequencies. You will need to take a little further to build a new waveform with this release, which includes d0, df and the output of the FFT. In order to calculate the df, please refer to the user manual on page 10-3. With respect to the scale that is output by the FFT, it must be same as input. Hope this helps to answer your questions. Thank you!

    See you soon,.

  • help with authorization of the ADE?

    Hello

    I downloaded ON my PC and I need to allow it. Now, my computer asks me if I want to replace the AdobeID by the new. I get confused, because OF is not yet on my computer, but I don't allow my ereader with my AdobeID.

    The question is, if the email address remains the same, but password changes, I will always be able to read the books I already have on the ereader? I bought via the ereader, whereas they were not on my computer before.

    When asking you TO 'replace' means replace the anonymous account which is currently my pc or can I replace what I had before on the ereader as well? Because if I have to replace the AdobeID on my ereader as well, then I won't be able to read ebooks that I put on the ereader.

    Thanks in advance!

    Kind regards

    Denise

    Many people seems to think that the use of Digital Editions with an ereader is

    'plug and play '.  It is not because there is a good amount of technology

    lurking in the background.  No offense, Denise, but I should put a

    view around the answers to your questions.

    EPublications are consistent with the Digital Millennium Copyright Act of 2000 (DMCA

    for short), which sets out the way they are managed.  There are

    restrictions on copying and printing of ebooks and these restrictions may be

    fixed by the authors, distributors and publishers using digital rights management

    (DRM).  At the same time, as Digital Editions library management systems

    need to build these restrictions to their programs.  In addition, ereader

    manufacturers can choose some options to integrate into their equipment.

    Some ereaders can be used without their registration with the manufacturer.

    But their capacities are limited.  Some, like the Kindle and

    iPads/iPods/iPhones, are related to a certain ebookseller (Amazon or Apple).

    All PC library management systems can access ebook sources without being

    recorded.  However, as you have discovered, some will impose limits

    on you if you do not save.

    ADE - registered or not - creates a small file of ID for each ebook and that

    contains information about the user.  So, you are right in saying that, if

    you use a different ID, you won't be able to read ebooks that you

    downloaded with (or without) a different ID.

    Your ereader also contains information on registration - if you are registered

    then the ID you used is embedded in its file ID and is associated

    with all of the ebooks that are downloaded/copied on it.

    All that being said:

    ADE is flexible enough, you've discovered.  You can allow it with a

    ID and then change it when you want.  However, because of the DMCA, it won't

    allow you to read electronic books other than those to this ID.  One solution is

    the other is to set up an Adobe ID which is independent of your email

    address (you can do even if the suggested format is an e-mail

    address) and use it.  If you change your email, you do not assign your

    eBooks.  However, for the moment, whatever ID you use must match

    the one that you used to download the ebooks.

    I can't tell you exactly what to do with your ereader, but the very idea

    apply.  You must register, and using the same ID that you did for ADE

    greatly simplifies things.

    I hope this helps!

For example, I'm going to fname lname, address, telephone, etc... How can I get these fields automatically on the other pages of the form?  Is this possible?  Any suggestions are welcome.

    If it's just a fill operation then make sure the fields have the same name. Then set the binding to the global level and all the fields with the same name will get the same value.

  • I am facing problem with playback of the audio recorded.

    What version of the Windows operating system is installed on your computer?

    If I understand correctly you are facing some problem with the audio recorded. There is no way to lose the sound after a few seconds; There seems to be a problem with the registration. I suggest you to run the game audio recording Fixit then try to register once more and check if it works.

    where should I call the get_line., in my script, I started after the loop as above

    Immediately after open from finifile is a good place:

    ...

    fINFILE: = UTL_FILE. FOPEN (vINFILE_PATH, vINFILE_NAME, 'R');

    -The first line always is a header, to be ignored

    UTL_FILE. GET_LINE (fINFILE, vINPUT_REC);

    ...

    Or you could do later as immediately before the LOOP.

  • work on FB4.5 and Flash5.5 simultanoiusly - lack of indicators of code with classes in the default package.

    Hello!

    I have installed Flash Professional CS5.5 and FB4.5 to work together. I just follow this tutorial: http://www.adobe.com/content/dotcom/en/devnet/flash-builder/articles/sharing-projects-flas hbuilder - flash.html and almost everything looks good, but unfortunately works in Flash Builder, adding new Classes, I don't have a default package accessible Classes. In this way I can't yet declare Sprite, the Array class and so on. In the code hints I will receive my current package classes only.

    I put the project FLA in Flash CS5.5 with cases like the package for my classes. It's for examle:

    com.myDomain.testProject where DocClass exists. By adding this path as the document to FlashCS5.5 everything works fine, I can easily run, debug movie in the Flash environment.

    Definition of this project by "Import"->"FlashBuilder-FlashBuilderProject"->"dossierprojet" pointing to the .fla file, it seems that the thing is going well. The project is defined, and even I had some problems with the name of the Document class (it seems that Flash Builder must have the Document class with the same name as the flie .fla) and renaming I can run or debug him and it works.

    But if I try to add the new class in the directory I find myself with no indication of code, and in fact no default package classes are supported. This means that I get errors when trying to create the instance of any common class etc. In the code hints, I get only my advice of package (see photo)

    fb1.jpg

    Maybe I misunderstand some basics of package and has done something wrong, but in general I don't want to put all my classes to the location of .fla but sort them upward in specific folders because I assume that the project is important enough.

    If you can help me, thanks in advance. Been to mess with the code is a part of the nature of the programmer, and when we find the answer that it feels like a King. When to address environments like that, there never is joy and happiness, but in most occasions couple uncensural of words at the end and an overview on the watch - agrrrhh I lost so much time :/

    I have several compositions nested in my project OVER a good bit of photoshop layers. I notice every time I post my layers/pre-comps using the z axis in my main composition (forward and back) I can't say if they are all using the front view, I can only say that she was moved when he disappears behind another layer. HOWEVER when I go the main composition that contains all of the items, I can see how it looks 'really' in rendered previews, as if all of a sudden I see exactly where I placed the layers, and it is really misplaced. Why can I not see this before I go? And why didn't he show me this point of view in the first place?

    FYI: I see the side/top view layers, but I does not help me much because I can't tell what the front looks like.

  • Need help with calibration of the battery

    I have a Vn7 - 591 g and it's basically old 1.

    My problem is my laptop stop without noticing low battery notification and without any warning since I updated my windows 10 November pro build.

    First, it would close down to the level of 15% without indication battery and then I looked at here and there and find the calibration procedure as I tried battery as the load calibration procedures to 100% in stop and go in safe mode and let it drain and recharge again, after the fact that now he stops at the level of battery by 30% or 25% without notice or warning.

    I tried battery reset thing pinhole also as suggested somwhere in this discussion.

    One thing I noticed when I put my laptop power in High-Performance option, low battery, that it just goes right into hibernation but when I plug in the AC adapter it shows battery 0% or 1%, and perception.

    so is it problem in my battery or Power Options or the problem is another?

    Any help will be appreciate and please answer quickly because I am sad with this problem. It is a one year old laptop around, I bought new.

    Hello

    Well, the wear level is quite high for a laptop one year old. Do you often use on the farm?

    It is interesting that hwmonitor reads the same amount as that of windows, stop so suddenly, because of the battery not calibrated... I don't think so. It may be the case even if the PCI that controls the battery charging does not correctly read the State. That would mean that you would need to change the battery (the peak is on the battery).

    You can try to run battery Eater: http://www.softpedia.com/get/System/OS-Enhancements/Battery-Eater-Pro.shtml

    This software will monitor your battery while meeting and then make a graph of it after a reboot. I don't remember if trace the graph based on the percentage, or the actual capacity of the battery.

    You can read more about what the software did here:

    http://Lifehacker.com/5657275/battery-Eater-benchmarks-your-batterys-capacity-so-you-know-what-to-ex...

    Also, would probably be a good idea to see if what happens on another operating system as well. For example, you can try to make a USB boot Linux, ubuntu and check if your laptop suddenly stops at the same percentage values. If it is not the case, which is probably something just with windows.
