• impact of the second leap 2015 to Application Java on Oracle in AIX

  Hello:

  I would like to get advice more communities DBA for the "second leap in the year 2015 problem" for Java application on the 11.2.0.4 to the AIX operating system oracle database.  Our explicit questions are commissioned in Java application:

  1. any impact to Java time back and comparison?

  2. no impact in objects API JDBC timestamp?

  So we should close application when the time approaches midnight, June 30, 2015 (for example: after 23:30 to June 30)?

  Should we rebounce all application servers?

  Or any code change must be made in any class of the Java API?

  Or, no need for any action?

  We have collected a SR of survey-3 for oracle support, they have not confirmed any need for action of RDBMS Oracle, quick to answer me on the impact to the question of Java.  Here is the link for 'Java API for Date class' to the Oracle's Web site:

  https://docs.oracle.com/javase/8/docs/api/java/util/Date.html

  Someone at - it interest giving me advice?  Thank you very much!

  Well Yes, probably

  but I guess that's a lot of work to put in place

  and all this work will be to see what happens if something changes in this second 2 window...

  I outweigh the cost against the risk

  the risk being a transaction or a process that can potentially fail which explicitly check/use long?

  > the cost... depends on how many people next to you will work on this

  the work and the cost of this work really deserve the conclusions you might be able to do?

• Performance consistency POF vs Java Seriailization...

  Hello
  I tried to compare the performance of Java vs consistency POF serialization so I wrote some examples of classes in order to compare the time taken to serialize and the size of the byte array created to contain the serialized bits. I found that the simple objects Java serialization has given the better results than the POF. I write the code online. Can you get it someone please let me know if the comments are correct or if a different approach should be taken for POF serialization?

  Hi Raphy,

  You should not use the getRawByteArray method, first because it is private to the buffer, secondly because it returns an array that is greater than the actually used amount of bytes. Similar in internal table of a StringBuffer, while toByteArray is similar to a new string with a correct internal character array returned by the toString method of the StringBuffer.

  Instead, you must use the toByteArray method which returns an array of bytes which is only as long as necessary, so the length is correct.

  In addition, I would take your time with a grain of salt values you POF serialization at an unfair disadvantage because it always starts with a byte of an array, and must reassign, possibly several times. Coherence itself collects the stats of the objects it serializes and pré-alloue a buffer that is probably wide enough so that no reallocation will be necessary.

  Also, you collect a large memory footprint by running your code in a loop and maintaining arrays of bytes that could lead to global catalogs that may influence the outcome of your time, more clearly that you have more objects, and part of your test POF has more objects because all Java serialized objects are always kept in a Member If your test is again a bias against the POF.

• AMX:inputDate input as dd-MMM-AA format

  Hello

  I use JDev 12.1.3 with MAF 2.1.3 I need to define a format amx:inputDate, I know its capture by the LOCAL format by default, but I need to put it because I need to collect the date and do a deed in the java class back-end, is anyway to set the format for the amx input format : inputDate as dd-MMM-yy?

  Thank you

  Hello.

  What you're trying to achieve exactly? The scope of the documentation for date. MinValue :

  Value ISO-8601 for date, datetime or time. This value may be presented to the user by using the local time zone specified on their device, but the value of support will be always ISO-8601.

  This means that the value that get you from the component always includes the date, time and time zone information schedule. If you need to manipulate, I suggest you have a look on the DateTimeFormatter class.

  https://docs.Oracle.com/javase/8/docs/API/Java/time/format/DateTimeFormatter.html

  Using the parse in this class method, it is trivial to get an instance of the string returned by the date java.time.ZonedDateTime. MinValue, for example.

• Multi-threaded in JavaFX game loop

  I am trying to understand works threading model of JavaFX, to determine the best way to write my game loops. This moment, my approach is this:

  EventHandler < ActionEvent > gameUpdate = event->

  {

  update of the world based on a timestep (see below) 33.3ms

  };

  gameLoop = new chronology (new KeyFrame (Duration.millis (33.3), gameUpdate));

  gameLoop.setCycleCount (Animation.INDEFINITE);

  My understanding is that:

  1. This should result in the game loop to run at around 30 FPS (the target frame rate), assuming that the gameUpdate does no more than 33.3ms.
  2. The changes I've made in the course of the gameUpdate causes a trigger pulse.
  3. This impulse is an event on the JavaFX application thread. Such an impulse ends a synchronization between the JavaFX application thread and a thread of rendering of the Prism.
  4. The gameUpdate runs on the same thread of request, so the pulse will run after the gameUpdate.
     By that I mean that the gameUpdate will never be interrupted by a pulse, which could cause the world to be returned in an intermediate state.
  5. Event handlers also run on the same thread, so I need not worry you synchronize them.
  6. Changes to the live nodes by event handlers will cause an additional impetus to be triggered.

  My questions are:

  1. I understand that correctly?
  2. When working with animations (for example. RotateTransition), this animation triggers its own pulses, actually being run to a framerate higher than the loop game?

  Thank you!

  > I tried AnimationTimer also, but that does not seem suited to the steps of fixed time...: 'the AnimationTimer class to create a timer, which is called in each frame, while it is active. This seems to indicate that the timer is called on each pulse...

  Yes, this is how the timer works, it is called on each pulse.  Generally, the pulse occurs regularly, 60 times per second.  However, if your code (or internal JavaFX code), a lot of work to do on a given pulse, for example you added 100 000 rectangles at the scene, then the impulse will have more than 1/60th of a second.  The AnimationTimer provides a hook you can hang off of to execute logic when occurs a pulse, but how many times it is called depends on the current frames per second (FPS), which the application is running under (which can vary from an intensive application graphic or logic).

  --------

  > I understand that well?

  I think that understanding is generally correct, except for the statement about additional impulses.

  > The changes that I made during the gameUpdate causes a trigger pulse... Changes to the live nodes by event handlers will cause an additional impetus to be triggered.

  This is not really correct.   Pulse will always occur 60 times per second (or as soon as possible if the FPS is less than 60 FPS).  Nothing in the application causes an additional impetus.  However, if the application scene is static and don't change not, then pulse runs very quickly because he has little work to do.  JavaFX has mechanism of sale under construction node.  Only Sales (or modified) nodes are displayed on each pulse.  Between pulses, JavaFX will merge all the changes at the scene to determine all the nodes for a given impulse Sales and just make these Sales nodes.

  For example, suppose that your chronology of animation for the game loop is set to trigger 30 times per second, then you could make a scene update on each pulse even.  If a scene update event handler is triggered on a strange impulse, an additional rendering will be on the pulse of odd to manage the sites updated.  If the same event handler is triggered on a same pulse, no additional rendering is required if the game loop is also updating the same nodes (because the nodes are already filthy and dirty nodes are only displayed once per pulse).

  --------

  If you want a very reliable timer which is called like clockwork and is not the potential system hazards pulse JavaFX, then you can use a standard Java Timer, but in doing so, you leave the nature single-threaded protected JavaFX environment when you run the code in the timer, so the Timer code can not update to the live scene graph nodes.  If the timer changes the State of the game which is shared by the event handlers and other reminders that run on the JavaFX UI thread, you will require thread and data synchronization mechanisms, which could get complicated quickly.

  --------

  I think that on the whole, the recommendation would be to run your loop to 60 frames per second instead of 30 frames per second (how you can as well use an AnimationTimer), if you want the best perceived sharpness (in the case otherwise, you find yourself with questions stuttering as such as Nvidia g-sync technology is built to correct, but g-sync as the technology is not widespread).

  You can look at the code sample case brick (from Java Oracle 8 samples), because there were some changes to increase the fine (I think the code passed explicitly to a schedule that you set in your question to use the AnimationTimer, but check).

  The eppleton game engine also uses the approach of AnimationTimer because it is the game loop.

  -------

  > When working with animations (for example. RotateTransition), this animation triggers its own pulses, actually being run to a framerate higher than the loop game?

  Transition animations will be returned to each impulse, they trigger not their own pulse.  The animation can also trigger code to use (on the animation of JavaFX thread) when the time for a keyframe.

  -------

  I think that the way of thinking of time and transformation in JavaFX is that it is not continuous, but rather composed of discrete locations in which work can be done, if the slots correspond to each pulse and get up to 60 times per second.

• Using DateTime in a cursor

  I would use a slider with OffsetDateTime/LocalDateTime values (JDK 8)

  I thought to convert time values to time format and transmit the zipper. However, I would like to link to DoubleProperty value the Slider and convert that into OffsetDateTime/LocalDateTime format so I can display the update in a label.

  From what I've seen, seems that I need to convert the double value back to long so I can then analyze this long value in a DateTime format.

  Is this possible?

• Type attribute ignoring JavaCast

  I have a Java object from the seller that returns a representation in long form of a timestamp. Unfortunately for me, this long must be multiplied by 1000 before make it the correct timestamp. Attempt to survey an error in MX 7 whole, even if I'm casting at long. Is there a way to circumvent this problem, or else another way to obtain a timestamp of a long?
  
  The error is thrown:
  
  Could not convert the value 1.162484964E12 in full because he cannot hold within an integer.

  Well, if you don't care the ms part your date (and you really can't
  Since your java class returns time unix):

  
  startDate = createDate (1970,1,1);
  DT is dateAdd ("s", unixEpoch, StartDate).;
  

  where unixEpoch is the value returned by your java class.

  BTW if you want to get the java time lag (ms since 01/01/1970) for a given date:

  
  t = Now ();
  t = t.getTime ();
  

• After the "new version" download Java 6 times, my plugin check page indicates that he has disabled my 'version outdated' and asks me to upgrade. What do I do?

  Background:
  I had this problem for several months now. This problem started when an update came to Java on the Firefox Plugin check. Quickly, I installed the new update of Java. But the Firefox update register that I downloaded, even though I refreshed the page. So, I got rid of the old Java and downloaded again the new Java. When the page has continued to post the same message he had before, I downloaded a few times more. Finally, Firefox stopped to say that I was at day. Then a few weeks later perhaps I check Firefox Plugin, and on the page it says that I'm overwhelmed in Java. So I downloaded Java again. But Java was still in the list, with the red and said that he had to be updated. I restarted the computer. Then I restarted Firefox Mozilla with no Add-ons. When Java appeared still to be updated, I gave up and did not something more on this topic.
  Problem:
  Today, I decided to check my plugins. Java was not updating the list, and at the top a banner said, "Missing JAVA? For your security, Firefox has disabled your outdated version of Java. Please install the latest version. "I clicked on"upgrade to the latest version"and was brought to the Java page. I clicked on the download button. My cache indicates that it was this same Java plug-in (see background) download (6). I chose the re - download anyway. But Firefox always insists on the fact that I him have not downloaded.
  Question:
  Should I go to the control panel of Java and change something? I have to fix a few settings on Firefox? Should I disable Java entirely, delete all the files related to Java on my computer and start over with Java? What should I do?

  Try to use http://ninite.com/java/ninite.exe to install Java. Please note that even if download you it you have to double click it to run and install.

• Since the 8.0.1 update every time you start Firefox POPs a box asking if I want to install Java Quick Starter 1.0. I say always Yes, but the next time he asks me the same question. Why?

  I thought once you allowed a plug being installed and authorized in Firefox it stay installed. Why should I allow it every time? I don't know what made the extension.

  Go to the Control Panel, double-click Java. In the Java Control Panel, select the Advanced tab the + various front and uncheck the box Java Quick Starter to remove the add-on. Restart firefox.

  Thank you

• When firefox loads I get an error message "cannot find / / / jpsnotify.exe." now load Firefox, but every time I go into something else, it seems. This started to happen when I downloaded a new version of java.

  I downloaded a new version of Java and then I started to have a "windows can't find c:\java\jre6\lib\deploy\jqs\ff\...------..» \.. \bin\jqsnotify.exe. now, this only happens when loading firefox. It happens through the use of firefox during the loading of other programs. any suggestions?

  This has happened

  Each time Firefox opened

  Try to reinstall Java. See using the Java plugin to display interactive Web sites content

  A quick search for jqsnotify.exe on Google indicates that it is related to the Java QuickStart option.

  You probably have some of the older than the needs/desires software legacy Java installed.

  Please see these sons of community message:

  After the installation of El Capitan, I get the message: to use the 'java' command line tool, you must install a JDK

  Just found this last Java does not work with El Capitan

  This is the Apple link to the legacy version of Java 6.

  First of all, I would like to try to identify what application generated the next message and update (delete) this request as the case may be. If you need to run Java then, as the Apple Support page says it's certainly preferable that your installation of Java entirely up-to-date with the Oracle's Java course. If you can get without Java, you should install it not - like the Flash, it should not be installed unless you have no choice.

• Extremely slow navigation that can cause Java tried to uninstall and reinstall but recieived Error 1719 warning every time I've tried to uninstall

  I have vista and I spent the last three hours, trying to solve this problem.  I concluded that I needed to uninstall Java and of course it uninstall not because of error 1719.  I found an incredibly detailed by a microsoft tech message, but none of the methods worked.  Anyone have suggestions or for this cause can someone explain what the problem is?  I can load some websites without problems but sites like facebook and things just do not work.  I write the site that I went to that as the detailed solutions that does not solve my problem, btw I wasn't the last suggestion lest I might seriously interfere with my operating system...

  Yes, I did a full scan with my updated Virus of McAfee program so I don't think I have a bug... Someone at - it ideas?

  This is the site with suggested solutions that didn't work.

  Some websites need a functioning Java install so that they can view items correctly.  Others require that JavaScript is turned on for the same reasons.  Java and JavaScript are completely different and independent processes.  You can specify your exact mistake during visits to sites like Facebook?

  Anyway your 1719 error indicates a problem with Windows Installer, the inability to install or uninstall a program.   It may be a problem in the registry so that you may need to use this option mentioned at the end of the link that you gave, or the current last that was in the sense of this link.  That you don't want to try?

  Have you tried restoring the system to move things to the way they were before you uninstalled Java?

  You can try restoring the system in Normal mode, if it fails, you can try it in safe mode, if that fails too, you can try it through the Startup Repair procedure.  If all fail in ways you can certainly tell the system restore won't work.

  Have you tried to run outside of the Windows environment?  If you have an installation DVD that you can start (or an option of startup repair via the F8 Safe Mode screen), try to start the system restore from the options provided when you walk down the path of the Startup Repair.

  Not to perform the Startup Repair (at this moment in time, maybe more later, but if and when, at the time, too, but look at your OEM recovery options first on restoring the default values), picks up and go into the option for the system restore option.
