• How to configure HA when vCenter is running as a virtual machine in one of the army?

  To install HA with VMware EVC, guests must be first maintenance mode before moving into the HA cluster. The problem is, vCenter runs as a virtual machine inside one of these hosts. If I stop vCenter downwards so that the host in maintenance mode, how do I setup with VMware EVC HA without using vCenter?

  If you do not feature vMotion, right down your vCenter VM and you unsubscribe eg. ESX1 can record for example. ESX2 then turn back on. ESX1 maintenance mode and then back ESX1 on your cluster file and exit once done maintenance mode. It goes the same for ESX2 and the rest of the ESX host.

• 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.

• The host CPU is not able to run 64-bit virtual machines

  I am running VMWare Server Console on a Windows 2003 64 bit OS 1.0.3 and prepare to create a 64-bit VM server to test a new application on.  This forum server works on is a SuperMicro SuperServer 6025 B - TR +.  I entered the bios and activated the virtual bios in the CPU settings.  However, when I start my VM, I get the following error:

  «You have configured the virtual machine as an operationg system 64-bit client.»  However, this host processor is not able to run 64-bit virtual machines or this virtual machine has 64-bit support disabled.

  I looked online and saw some references to allow an EM64T which was to be activated but I do not see this option in my BIOS.  Someone at - it any other suggestions as to what I have to do to get the virtual machine to use the 64-bit compatibility.

  Unfortunately, the 1.x server logs are a little sparse in this regard.  However, it seems that you have mixed steppings of physical processors.  In this range of models, Intel changed the VMCS review between the Bx steppings and Gx steppings ID, making it incompatible for the execution of VT - x.  Realizing their mistake, Intel has provided to OEMS for a microcode patch that makes the revision ID the Gx stepping VMCS matches that of the Bx stepping.  OEMs distribute this patch of microcode as a BIOS update.

  In short, an update of the BIOS of your system provider should solve the problem.

• Catch22, how to change the settings for VirtualCenter, running as a virtual machine

  I'm running as a virtual machine under ESX 3.5 VirtualCenter. I want to change the setting of this virtual machine, but of course, the only way to change many parameters of a virtual computer is to stop the guest OS. I just changed the type of NIC on all my virtual machines, except VirtualCenter, using this procedure:

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1007195

  I want to change the adapter for VirtualCenter to improve vmxnet as well. How to work around the Catch22 needing VC running to change virtual machines but requiring judgment VC to edit it?

  Laughing out loud

  Shut down the virtual computer. Open the VI Client and instead of the IP address / hostname of the VC Server enter the IP address / hostname of the ESX host. You must use an ESX account for it! If in doubt try then the VM VC is still under way.

• 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,

• 64 bit VMs in ESX/ESXi 4.0 that is running as a Virtual Machine in VMware Workstation 7.0.1

  I created an ESX4 host in VMware Workstation 7.0.1 as a Machine with 4 GB of RAM, 2 vCPUs and 1 (25 GB for installation) VMDK virtual and more later added 75 GB VMDK as an iSCSI LUN using openfiler.

  My vCenter Server runs as a Virtual Machine with SQL Express Edition 2005 DB.

  I want to install a Windows Server 2008 R2, which is a 64-bit as a virtual machine within the VM ESX4 embedded operating system. Is this possible?

  Hello

  as this comment by DOC from VMWare, in the 'internal' invited you will just be able to run 32-bit clients, never a 64 bit one.

• VCenter U1 patch that runs in a virtual machine.

  Hello, I have recently updated my ESX infrastructure to vSphere 4.0U1. I run Server 4.0U1 with Update Manager vCenter. I'm confused as to how I can keep my current VM with patch vCenter. When I try to scan the virtual machine with the Update Manager - I get the following error:

  CK-VCENTER VM is a virtual machine that has installed VMWare or VMWare vCenter Update Manager vCenter. This virtual machine will be ignored for scan or clean-up.

  I know vCenter running as a virtual machine is officially supported by VMWare - so I'm confused as to how I can keep this compatible virtual machine. I have several tasks such as improving the VM hardware version 7 to 4, while keeping the of Windows OS virtual machine patched, etc. This must be a common situation for those who have a similar setup as me. Please notify.

  There are no Patches VMware vCenter, just for vCenter and those are re - installs the application.  Regarding Microsoft security patches, you would have to patch as if it was physical.  We use Shavlik.  But you can use WSUS or even windows updates.

  with regard to the update of the virtual hardware. Go to the ESX, the guest host is registered on, stop the VM vCenter and upgrade the equipment this way.

• 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.

  Lax.nl.currentvm = JVM_PATH

  It seems to work properly until now.
