• Cannot create an instance of the java virtual machine

  Hi when I try to launch my sql developer get this error

  Cannot create an instance of the java virtual machine located in the path C:\Program Files\Java\jdk1.6.0_38\jre\bin\client\jvm.dll, but I do not have the file in the location

  I'm trying to do

  BI CHAOS: SQL Developer: cannot create an instance of the Virtual Machine Java

  Cannot create an instance of the Virtual Machine Java

  but am not able to locate file product.conf in my machine
  

  OK, we lost time because you said never explicitly release of SQL Developer in use, and then, when I deduced this wrong, you went right with it, rather than correct me.  Remember the line from Blade Runner when Harrison Ford hits Rutger Hauer in the head with a pipe?  Than hurt!

  Anyway, since the last post (because of the osgi references in the file ide.conf) I see that you are using a version 4.0.x of SQL Developer.  You must update the file product.conf with the smallest Xmx value in order to create an instance of the JVM.  If you have not yet found the product.conf file on your system, this might help: http://www.thatjeffsmith.com/archive/2013/12/oracle-sql-developer-4-windows-and-the-jdk/

  Otherwise, ask someone in your organization COMPUTER help - keep in mind that AppData is one of those hidden Windows directories, so you'll have to tell explore to make it visible by the organize > Folder Options > view > hidden files and folders parameters.  In addition, you should use Java 7, not Java 6 - try to get that upgrade to the latest version of jdk1.7.0_xx (currently 60, I think).  Since you never said if your JDK is 32-bit or 64-bit, I can not say to use an AddVMOption, Add32VMOption or Add64VMOption.

  People,

  This issue has been resolved,

  Details of the problem:

  RAM 512 MB only, use JVM parameters

  "" Arguments of memory in JAVA: -Xms512m-Xmx512m ".

  If WL struck to use more memory for the start and the stop MedRecSvr2, 3 (managed server)

  Please read the following steps to correct,

  1. open Oracle VM Virtual box

  2. go to settings and select the system option (make sure that all OS turns off).

  3. go in card mother in this window select Base memory previously is changed to 1920 MB (1.875 GB) 512 MB.

  4. click on Ok.

  Then the allocated RAM will be more, for Weblogic doesn't get knocked because of insufficient RAM memory.

  
  

  Respect,

• is it a good idea to run the JAVA virtual machine inside the hypervisor?

  If I want to write a global user inside the hypervisor platform and you want to reuse some java lib, it's a good idea to install and run the JAVA virtual machine as part of global programs of the user inside the hypervisor? Thank you.

  Maybe you listen to the wrong people?

  The ESXi hypervisor is pretty well stripped of the linux console you are talking about, there is a thin busybox linux like environment, but you are strongly advised not to run anything in there.

  Performer of applications within this console may have all kinds of side effects such as severely affect the performance of your computer virtual guests.

  Why the hell would you want to run the JAVA virtual machine inside the hypervisor? What is the reason why you want to do this? If it's because you get a better return, then you're wrong, the console becomes just a little bit of resources available on your host computer.

  If this is to go directly to the features that the hypervisor provides then the VMA we're talking is the answer.

  So getting back to your question initial for EACH use case that I can think it's a very bad idea.

• CF 9.0.1 Solr does not have the Java virtual machine path

  As part of the security of some of our machines for use of DoD, need to maintain the versions of Java.  To do this, we install the latest JDK and use the server settings > Java and JVM > Machine way Java virtual to then tell CF to use it.  We have done this since CF4 without any problems and when we moved to CF6 + we continued the process, but also after having what we then delete the folder of jre in runtime folder leave the CF is. Well I have just the program installation and installed my first CF9 + Win 2008 R2 server and after doing this the Solr service does not start.  This had me so dig in its folder structure and it has its own folder of the jre in its folder structure as well.  But using Sysinternals Process Monitor, I can see the service Solr uses NOT the folder of the jre from the inside it of own structure but is actually going up and 'try' to use the runtime\jre folder that I have deleted so it causes the service to fail.  I can actually delete the solr\jre folder as long as the runtime\jre folder exist.

  There are so many problems with this.

  • SOLR has yet another installation of Java within itself
  • SOLR does not use its own Java, even if there is a copy it
  • SOLR does not respect the setting Java VM path together

  Adobe has responded to my bug with the location of the solr configuration variable to point to the external JAVA virtual machine.

  ColdFusion9\solr\solr.lax

  Lax.nl.currentvm = JVM_PATH

  It seems to work properly until now.

• How to replace oracle JInitiator with other Native Java Virtual Machine?

  Dear Experts
  I installed ony my server not IBM application called "IBM Filenet IDM webservice".
  It is used for the analysis documents aweb application.
  The problem is that this product uses other Machines virtual Java.  IBM.
  This causes a conflict with Oracle JInitiator.
  So, I decided to depend on Sun or IBM java virtual machine.
  But I don't know how to do this.
  What are the system requirements?
  Help, please

  Hello

  By default in formsweb.cfg you have a section called \[jpi\].
  If you run the form with config = YPI added to URL Sun JRE will be used instead of Jinitiator. Note that you must specify correct jpi_classid in formsweb.cfg match the version of JRE to your client computers.

  To configure forms server to use any version of JRE installed on the client computer, you can create a section in formsweb.cfg

  \[jpidynamic\]
  baseHTMLJInitiator = basejpi.htm
  jpi_download_page = http://java.sun.com/products/archive/j2se/1.4.2_09/index.html
  jpi_classid = clsid:8AD9C840 - 044F-11 D 1-B3E9-00805F499D93
  jpi_codebase = http://java.sun.com/products/plugin/autodl/jinstall-1_4-windows-i586.cab#Version=1, 4,0,0

  and to call the forms with configuration of parameter URL = jpidynamic

  It will be useful,

• How to create the new virtual machine vm existing in the data store on ESXI

  I have ESXi and couple of virtual machines.

  I have the vsphere client on Windows 7.

  I then deploy the ovf from the vsphere client vm and it began to import my VM 30 GB.

  In the morning, I realized my vm with a vmdk file file has been transferred in the data store

  But I couldn't see any virtual computer.

  Now I don't know how to turn on this vmdk file that is in my data store

• kill the java virtual machine with Runtime

  Hi all

  I m trying to set up something funny in my web site.

  what I want to do is to let anyone stop the server, if someone sends a message on the site.

  I tried the code below in a java application is and fedora. He did run, but did not kill the java process.

  Could someone point out if I'm missing something?

  Thank you.

  {code}

  String stopCmd = ' ps - ef | grep java | XARGS kill. "
  System.out.println (stopCmd);
  Duration rt = Runtime.getRuntime ();
  RT.exec (stopCmd);

  {/ code}

  You must use the other form of exec() who accepts an array. You order must be

  String[] stopCmd = {"/bin/bash", "-c",  "ps -ef | grep java | xargs kill"};

  Note the position of the citations - it is very important.

  You should also read the article "Pitfalls" (when Runtime.exec () not - JavaWorld) and implement ALL the recommendations.

• can not find the java virtual machine

  I got an error message when you try to compile. At one point, he worked, but maybe I messed up one of the environment variables.
  
  C:\Documents and Settings\jm > mxmlc
  Error: could not find a JVM.

  To answer my own question and save people future pain. Under Windows, when Java is unable to find the virtual machine, you must do

  Start > Control Panel > system > advanced > Environment Variables

  and implement the variable user "java_home" to the JDK with oblique lines as follows:

  C:/Program Files/Java/jdk1.6.0_06

  You don't put ' / bin '. If you put Java into a different folder, you must change the java_home accordingly. Now I can move on with life.

• Satellite A300-18 has: how to increase the screen resolution

  I have recently buy a Toshiba Satellite A300-18 a, and I want to increase the resolution of the screen.
  Currently the max resolution is 1280 x 800.

  Does anyone know how to increase the resolution?
  Where can I find the drivers to increase?

  Thank you

  Henrique

  Hello

  I don t think a new graphics driver would allow a higher screen resolution on your laptop A300.
  Have you checked your manual for more details?

  I downloaded the user manual of the Europe of Toshiba page and discovered that the display is a 15.4 WXGA 16Mill colors with the following resolution: 1280 horizontal and 800 pixels vertical.

  It seems that you are already using the highest available resolution and therefore you will not be able to wear to higher values.
