• 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.

• Definition of reserves on the running JAVA Virtual machines

  I recently came across an overview of VMware performance that had a page essentially recommending reservations memory setting for the running Java virtual machines (see table). We have Java environments and did not have performance problems or complaints so, I doubt that I would implement any changes. However, I am curious to know if it's even a better practical recommendation, I could not put the date on the document so I wanted to see if someone had updated or current information for vSphere 4.X, 5.X environments.

  In General, we only use reservations memory to avoid the overhead administrative and operational increased. If we have never not a necessity, I prefer to use reservations to pool resources rather than granular level VM reservations.

  In my opinion, if you use the reservations are a regularity no exception in your environment, then you can use these rules.  That said, if you don't have no problem, I wouldn't change anything.  I've also linked a new document below.

  It's too generic to mean anything. The application is hidden the real error message. You got when you did the tnsping and obtained "TNS-12535: TNS:operation has expired. Now THAT's an error.

  This indicates a problem firewall and routing. You said earlier you could ping the server, but now we see tnsping fails. Two different protocols of usage, so that both the successful ping turns out a valid physical path, it guarantees not that all traffic will pass. What happens with

• 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.

• 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,

  I see nothing on the 'Microsoft Java Virtual Machine' in the error message you posted... and the MS JVM was not offered by Microsoft because it has been removed from Windows XP Service Pack 1a (Feb 2003) due to a legal settlement between Microsoft and Sun.

  Any developer wishing to use Java these days should use Sun Java, not the version of the Microsoft.

• 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.
