Events shown in the range of navigation when you view the properties of the system for recording of JFR

Which record the events shown in the range of navigation when you view the Properties tab system for a Java flight recorder? I'm guessing that they mark the time for JFR's writing of the events on the disk.

I ask because, during the capture of a lot of information with the help of JFR, we see two effects that correlate with these events: (1) CPU usage ramps up a little bit between an event and the back then, level departure after each event, even if the application workload is constant; (2) the clock used to time stamp on all the events THAT JFR capture high-resolution seems to run more slowly in the period following immediately each of these events, perhaps for the period while JFR is written to disk. The slowdown of the clock appears as an increase in the rate of events shown in the range of navigation in other tabs - I also analyzed the events selected out of the original EN file to check their apparent rate.

I see this on Java EE applications running on JBoss EAP 6.x on Java 7 on machines virtual small vSphere.

The events shown in the navigotor range in any time must appear at the same time they are created. not when they are written to disk which can be a little later, depending on the settings.

In the System Properties tab, you generally see a single spike per segment in your record. You should see the same thing if you go to the tabgroup events and enable only the Java Virtual Machine system property / Initial if Types discovered.

As for the damages of its use and CPU timestamp, it sounds interesting.

What exact version of Java 7 you use, there would be some bug fixes in later versions.

  • Problem regarding content previously highlighted when you view the file in Acrobat DC.

    I have a problem with the content previously highlighted when you view the file in Acrobat DC. There is no problem in earlier versions of Acrobat. I pointed out the portions many documents with a point culminating opacity 50% and now shows the text in black and white and highlighted portions are not readable. This only became an issue when I recently installed Acrobat DC. The system is Windows 7. Y at - it a setting I need to select to make the text readable again?

    To change the color and opacity of the commentary on the matches of the current document, you can use script below.

    Note : this script will replace the opacity settings and the color of all the comments of highlight for PDF files open. Please save documents before store you settings to highlight comments. This script can be used until a fix is available.

    Steps to follow:

    1. open all PDFs in Acrobat DC comments are present in the games.

    2. press Ctrl + j

    3. in the lower part of the text, copy the Script below.

    4. Select all of the text copied in the previous step, and then press Ctrl + Enter

    5 opacity of all comment games goes to 100% and change color to light gray.

    *******************************************************

    var hightlightColor = color.ltGray;

    var highlightOpacity = 1.0;

    DDP = app.activeDocs;

    for (docNum = 0; docNum)< pdd.length;="">

    commentArray = DP [docNum] .getAnnots ();

    for (i = 0; i< commentarray.length;="">

    If (commentArray [i] .Guy == "Highlight": game commentArray [i] == "HighlightNote") {}

    commentArray [i] .opacity = highlightOpacity;

    commentArray [i] .strokeColor = hightlightColor;

    }

    }

    }

    **********************************************************

    You can change the opacity (highlightOpacity in above script ) for any value between 0.0 and 1.0, where 0.0 is transparent and 1.0 is opaque.

    Some possible values for the highlight color (hightlightColor in above script) are: color.blue, color.cyan, color.yellow, color.gray, color.magenta, color.red, color.green.

  • I have error code 8024200d when you try to update and install SP1 for Vista

    I have error code 8024200d when you try to update and install SP1 for Vista. I'm currently running Vista Ultimate. Any help would be appreciated.

    Thank you!  Matt

    Matt,

    The 8024200d result code indicates WU_E_UH_NEEDANOTHERDOWNLOAD
    Update Manager did not install the update because it must be downloaded again.
    Suggest you download and Save the complete stand-alone package of Vista SP1.

    Links to the standalone versions are on this page because you validate that the edition of Vista is x 86 (32-bit) or x 64 (64-bit). You can see the architecture of the system of opening in the Panel and next to the search System system type: Windows Vista Service Pack 1 (SP1)

    Before attempting to apply the SP1 please consider this information-

    If you choose to install Windows Vista SP1 via the standalone installer available on the Microsoft Download Center, Microsoft recommends that you first check Windows Update and install all drivers in option. Read the Articles in the Knowledge Base 948187 and 948343 for more information.

    Suggest you to create a folder on the root drive (the drive where Windows is installed, usually C:\) and name SP1.
    Move the downloaded Service Pack in the newly created folder.
    Disconnect all the devices, printer, external USB hard drive, etc.

    Then, Configure the system starts in a clean condition
    After you restart the worm as a clean boot, apply SP1.

    If there is still a problem with the installation of SP1, MS offer support chat and free e-mail to "help you to download and install service packs" here-

    Hello

    1. is that the copy of windows is enabled?

    2 is the issue limited to the installation of a security update Cumulative for Internet Explorer 9 for Windows Vista (KB2699988)?

    I suggest to perform the steps in the following article and check.

    Method 1: run the Windows update troubleshooting tool and check.

    The problem with Microsoft Windows Update is not working http://support.Microsoft.com/mats/windows_update/

    Method 2: I suggest you to put the computer in a clean boot state and check if Windows update installs successfully.

    To help resolve the error and other messages, you can start Windows vista by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    Sometimes when you view an Acrobat file created by others, square replace some characters.  How can I stop this?

    Hi John -.

    It seems that no one has answered your question. Sorry for the long wait!

    Squares can replace characters when you're dealing with missing fonts, or who are poorly integrated. It is important to see the text, you can ask the person creating the document to convert the PDF image pages PDF file, which then displays the fonts.

    Places instead of the characters may appear if you are using a scanned page, for example and capture the text.
