• Cannot open 2 Virtual Machines at the same time to access the same database

  People,
  
  Hello.
  I'm installing RAC Oracle Database 11 g 2 system with 2 Virtual Machines (rac1 and rac2) on top 3 VMPlayer.
  
  The VM rac1 and rac2 when one of them is stopped.
  Their locations are F:\VM_RAC\rac1 and F:\VM_RAC\rac2.
  
  
  I opened rac1 rac2 is running. But this error message appears:
  
  Error: "cannot open F:\VM_RAC\sharerac\asm1.vmdk drive or one instant records, that depends. Reason: cannot lock the file. »
  
  
  While rac1 running, I opened rac2. But this error message appears:
  
  Error: "cannot open F:\VM_RAC\sharerac\asm1.vmdk drive or one instant records, that depends. Reason: cannot lock the file. »
  
  
  2 error messages are the same. This means that I can not open 2and rac1 rac2 VMs at the same time. When we run RAC system, must open 2 "machines" or machines to more than 2 at the same time, so that all machines can access the same database server.
  
  My question is:
  
  Can all folk tell me how have rac1 and rac2 run at the same time?
  
  Thank you.

  Unfortunately no, Oracle RAC requires that all nodes can visit the same set of shared disks. If your database resides within the DSO, each instance ASM (one per node) must also see the same set of disks to ASM diskgroup containing the data of the database files.

• Restrict 2 virtual machines on the same host at any time.

  Hi all

  I am implemented in virtual machines as an HA pair and would limit the virtual machines to be on the same ESX host, someone did that? or can someone point me in the right direction?

  Thank you

  Hi Amar,

  You will need to create a VM host affinity rule but this DRS must be activated, see page basic guide System Admin. 72 of link http://www.vmware.com/pdf/vsphere4/r41/vsp_41_resource_mgmt.pdf

• newbie question - vmdk transfer on another virtual machine on the same host

  Hello

  can I transfer a vmdk 1 vm to another and mount it?

  I have a vm of windows server with a 2nd virtual hard drive that has data on it. rather than to make a copy of file in a file to another virtual machine with a 2nd hard drive and then delete the second original disk, could I just disassemble and remove the second hard drive to the original virtual machine and then attach it as an extra hard drive to the second vm?

  pointers would be appreciated.

• DHCP server virtualized inaccessible by the physical host computers

  Hello.

  I set up a DHCP under VMware Server 2. It is accessible by the virtual machines on the same host, but not by physical machines on the network. They can ping its IP address, but do receive any DHCP offer at the start of it. Are there additional configurations that I have to look?  The VMware networking is configured in bridged mode.

  Thank you.

  Hi Rico,

  You need dynamic nat (for available IP addresses) for the two side to every subset of remote access to the other side remote subnet and so they can access every other subnet as if both from the traffic from your central location.

  example:

  Say, this IP (10.10.10.254) is unused IP to the central office, allowed to access remote tunnel 'A' and 'B' of the site.

  object-group network SITE-a.
  object-network 192.168.42.0 255.255.255.0
  !
  object-group network SITE-B
  object-network 192.168.46.0 255.255.255.0

  dynamic source destination SITE-a. 10.10.10.254 NAT (outdoors, outdoor)
  public static SITE SITE-B-B

  destination NAT (outdoors, outdoor) SITE-B 10.10.10.254 dynamic source
  SITE static-SITE a

  Hope this helps

  Thank you

• I had the opportunity to see all the drives in windows 7 and XP virtual machine on the same screen. He suddenly disappeared, and I need.

  As I set up my computer with Windows 7 Professional and XP virtual machine, I could see all the readers, W7 and the virtual machine on the same screen. I can't do now for some reason any. All I can understand what is is past is that I got a page long list of automatic updates of W7 and some XP updates and as far as I know, the current page of readers has disappeared since then.  I need this feature if I can transfer files between W7 and XP because some of my programs are in one program of windows. I have nothing special when I installed XP to achieve this functionality, so I really don't understand what it controls.  How can I get that back?

  I have solved my problem by trying everything that moves. Here are my steps:
  -Open Virtual PC and minimize it
  -In the Windows 7 machine, click Start click all programs
  -Select Windows Virtual PC
  -Select Windows Virtual PC (in the drop-down list)
  -When the window opens, right-click on Windows XP Mode
  -Select share >
  -Select the homegroup (read/write)

  -Minimized open Virtual PC
  -Select my computer
  Windows 7 disks will be under other

  I hope this works for you also. As I said, it worked like this until I had a huge list of automatic updates of Windows 7 and XP more some updates. Apparently, one of them cut something.

• Activation of Windows still necessary even if the virtual server on the same hardware to restore

  Hello, I hope someone can answer this.

  Our virtual machine running vmware server ESX 3i 3.5.0 has 2 hard drives, datastore1 and datastore2.   All of our virtual servers are stored in datastore2.   Our hard disk with the datastore2 crashed and he had to be replaced.    We have backups of our virtual servers in datastore2 virtual appliance.

  To solve the problem, we replaced the hard drive crashed and then restored by using the virtual appliance backups, once restored, we noticed that the Windows 2008 requires that the activation of the licenses.

  My question is why does windows need activation when we restored the virtual server for the same hardware? The only thing that has changed is the hard drive.

  Thanks for any help on this issue.

  Export/import unfortunately OVFs does not have an option (at least I'm not aware) to maintain these settings. What you can do - when exporting the virtual machine as an OVF - also download the machine virtual . VMX and .vmxf files. After re - import the OVF, remove it the ESXi host inventory, download the two * .vmx files and add the virtual machine to inventory. -Once asked if you copied or moved the VM on the first power-select "I moved it.

• Tagged management VLAN and the virtual machines on the same VLAN

  I'm faced with a problem related to our Brocade switches newly acquired and get the private VLAN to work on trunk connections to our ESX servers.  Every time I try something different, he creates a new problem.

  In our configuration, our management of VLAN is not tag and we have a VLAN for this management network that is placed on our switches VLAN no marked native.  We also have virtual machines hosted on those same ESX servers that are on the same VLAN and everything works fine.  However, when I change the ESX management to carry a label on this VLAN and change the switchports accordingly (IE no untagged VLAN native), management work, but hosted on the ESX Server machines that are on the same VLAN can get no network connectivity.

  Is it possible to have a management network labeled and also the host of virtual machines on the same VLAN or is it totally impossible?  I'm not very familiar with networking behind ESX, so I apologize if this is a dumb question with an obvious answer.

  Thank you

  Is it possible to have a management network labeled and also the host of virtual machines on the same VLAN or is it totally impossible?

  Yes, it is possible... why it doesn't work for you I don't know, but try the following:

  1. set up the Group of ports of VMS to use VLAN;

  2 configure the interface of management VMkernel port group use VLAN;

  3 configure the physical switch port to allow to this VLAN and put the default VLAN natively for these interfaces.

• No ping between virtual machines

  Hello

  I use VMWARE 7 program... I installed two virtual machines (windows server 2008 and windows 7)... I have attached two pic for each other... .my problem is... There is no rattling between these two machines... I disabled the firewall in both entities... How you can help me in this...

  My respects

  Post edited by: a.p. - changed the subject of the "Greetings" to "no ping between virtual machines.

  I do a bit of practice for MCITP study... In windows server 2008, I use Bridge and in the Windows NAT using 07:00

  Well, I guess you should start your trip MCITP become familiar with the IP configuration and routing

  Addresses that you configured do not work that way. Assuming that the physical - bridged - network (if connected) is 192.168.100.x, you may be able to access the Windows Server 2008, but you will never be able to access the virtual from Windows 7 computer with the NAT configuration, because NAT is running on another network (vmnet8 - 192.168.201.x). Depending on the need or not to be able to access the outside world of the virtual machine, you should consider is instituted two virtual machines with an IP address in the range of vmnet1 (Host-Only - 192.168.80.x) or vmnet8 (NAT - 192.168.201.x). In the case of NAT, configure the virtual machine for DHCP or use IP addresses between x.x.x.3 and x.x.x.127.

• run multiple virtual machines on the same shared drive

  I wonder if anyone knows a way to use disks of persistent nonPersistant style to function similar to Citrix Provisioning Server.

  My company uses Terminal Server servers and wants to be able to easily update all servers at the same time.  I know that with Citrix, it is possible to have a 'master' boot drive which the other launch initially out of.  To 'Refresh' your servers, you turn them off, put to update the 'master' then restart them... and viola, all are now updated.  I want to do the same thing, just without Citrix.

  I know that I can use a non persistent disc do not save the changes, but is it possible to have launch several virtual machines off this 1 disk?  I did some research and I continue to come from the small articles/blogs referring to something like this, but either they don't go into the details or they do not seek to launch several virtual machines out of it.

  This is a Citrix provisioning feature. The best you can do is try related clones. They share the same basic disk.

  Do some reading that this is probably the closet for what you are looking for.

• How to switch between multiple windows in the same application?

  Hello

  I use OS X Capitan version 10.11.13 and I'm trying to find an easy way to switch between multiple windows in the same application by using CTRL + alt or different keys.

  Here is what I feel...

  Let's say I have Outlook, Google Chrome, Safari, iTunes and apps 'about this Mac' open.

  I open the new message window in Outlook and another Chrome window. I have therefore 2 separate windows in Outlook and Chrome.

  With that, I'm unable to move the composition and the window main outlook which is so annoying. Let's say I want to read the emails by the prospect main window and transfer of the content of the compose window! The command + tab doesn't take me to the main window of Microsoft outlook! Even if there were the last visited / applications window. This constraint is not intuitive, unless it can be configured in the settings?

  Strangely, I can't switch to the "about this Mac" window.

  The work around is to use the function (F3) mission button and click on the window, that I want to use or click the "Outlook" application on the dock icon and choose the window in the list.

  Does anyone know how switch between different windows in the same application by using a key combination or one another method other than listed above?

  Thank you

  Avinash

  In general, an Application that can open multiple windows provides a "Windows menu" you can choose the window you want.
