Internal network for clients on the same host?

• VM on the same host and vSwitch talk internally?

  VM on the same host, using the same vSwitch automatically talk to each other internally on the host when they need pass data without using the NETWORK interface card or is there something specific that needs to be configured to do?

  Thank you

  With the virtual machines on the same vSwitch network traffic will proceed on via virtual network cards so the interaction network will not differ from the VM to communicate to a physical host.  Network traffic between virtual machines (assuming that they are on the same VLAN) will stay in the vSwitch and not go through the physical network on the host layer.  Thus the inter-VM traffic can exceed the speed of the NIC port in the vSwitch.

  vSphere includes VM Communication Interface (VMCI) that allows a host to communicate with the virtual machines without going through the network layer.  You can also enable VMCI for VM VM communication.

• Method for patching only host ESXi4.1 and VC is on the same host

  Hello people,

  I'm patching one of the ESXi, 4.1.0 348481 and Vcenter Server 4.1 Update1 (VM) is sitting on the same host ESXi. Please let me know how I can this patch

  a single host as the Vcenter also will restart. I'm looking to patch manually rather than Update Manager. How patch manually the ESXi host as there is no rounds in ESXi and what serves the Cli. If his VCLI then what is the command for the application of patches and download link. I'm looking to get the procedure. Any help on this

  will be well appreciated.

  Thank you

  vmguy

  If you have another host, you can vMotion your VM vCenter to it, then use AUVS to patch.  If a stand-alone host, then you will need to turn off vCenter and all the guests and try the method below

• VM to the communication of the VM on the same host

  I poured on the network and a few other discussions docs but I can't seem to find how VM to the communication of the virtual machine runs on the same host.

  If I have 2 VM on the same host in different subnets connected to the same vswitch can they speak directly? or have packets across the physical network and vice versa in? I don't know there must be a way for the s vm on the same host, vswitch speak directly, can someone please give me some advice on how it works and what are the limits.

  Thank you

  If it is plugged into the same vSwitch as what connect two servers on the same physical switch on different subnets, he won't have to work.  There must be some sort of Firewall / routing to have these two systems across different networks.

• Install the MDW and the mobile client on the same platform

  Hi all

  We implement our 11g Oracle Database Server from Mobile environment and I was confused about something I read in the Release Notes (http://docs.oracle.com/cd/E22663_01/doc.11100/e22675.pdf).  In section 3.2 says 'do not install MDW and the mobile client on the same platform.'  Did mean really say 'platform' or does really do not install the MDW and the mobile client on the same device?  We are a store of Windows 100% - the mobile server is installed on a Windows Server machine, we plan to develop with Workbench Mobile database (GMD) on a Windows 7 desktop PC, and we intend to run the client mobile Windows 7 tablets. The Release Notes say that I can't do this?

  Yes - the way it is written is a bit confusing.    We will correct it in the next version of doc.    What we were trying to say, is do not install them on the same system.    Thank you for this comment.

  Kind regards

• MSSQL server VM cluster should be in the same host or different hosts with RDM

  Could someone me on how to place the code SQL cluster s VM with RDMs in ESXi hosts for advice.

  What is the best practice to place the SQL VM s in ESXi hosts.

  Affinity or an anti-affinite...?

  Appreciated your valuable answers.

  Depends entirely on the use case.

  • 2 MS SQL nodes on the same host to see the availability of the software
  • 2 nodes on different hosts to see the availability of the equipment

  I'd say MS Clusters on the same host (at the time of HA and vSMP FT) are redundant VMware features and represent an increase in management fees. The MS cluster on hosts provide something in addition to what VMware vSphere alone can provide!

• PowerCLi script to check if 2 virtual machines are on the same host

  Hello

  I'm nubby on PowerCLI and I would like to help in the construction of a script.

  The script should check if two virtual machines (named test1 and test2) are running on the same host in a vCenter and send a notification (email), if they do.

  Something similar with affinity / anti-affinite DRS rules (but not through the DRS enabled on vCenter).  My focus is on the affinity. In case this happens, I need vMotion one of them on an another ESXi host(manually or automated).

  What I have done until now is the following:

  Get - VM | Select Name, @{N = 'Cluster'; {E = {Get-Cluster - VM $_}}, '

  @{N = "ESX host"; {E = {Get-VMHost - VM $_}}, '

  @{N = 'vCenter'; E={$_. "(ExtensionData.CLient.ServiceUrl.Split('/') [2]}}, '"

  @{N = "Datastore"; {E = {Get-Datastore - VM $_}} | `

  Export-Csv - NoTypeInformation C:\Scripts\file.csv

  That becomes all the VMS and export a CSV file information:

  Name	Cluster	ESX host	vCenter	Data store
  test2	cluster_test	ESXi_test1	vCenter_test1:443	datastore1
  Test1	cluster_test	ESXi_test1	vCenter_test1:443	datastore1
  For1.local	cluster_test	ESXi_test1	vCenter_test1:443	datastore1
  VM1.local	cluster_test2	ESXi_test2	vCenter_test1:443	datastore1
  VM2.local	cluster_test3	ESXi_test3	vCenter_test1:443	datastore1
  VM31.local	cluster_test3	ESXi_test3	vCenter_test1:443	datastore1

  Thank you.

  Try like this.

  $tgtVM = "test1", "test2".

  Get-VM-name $tgtVM | Group-object - property VMHost | %{

  if($_.) County - gt 1) {}

  $vm = $_. Group | Get-Random

  $esx = $vm. VMHost

  $tgtEsx = get-Cluster - $vm VM | Get-VMHost | where {$_.} Name - not $esx. Name} | Get-Random

  Move-VM - $vm - Destination $tgtEsx VM - confirm: $false

  }

• VShield service Manager installation and vShield app to the same host ESXi

  Hello, I'm planning on vCloud Director assessment in a laboratory with only a single ESXi host.  When I try to install the app vShield service I get the following warning: do not install on a host or a cluster where the VC or the vShield Manager resides. This can cause network problems. The following IP address must be a unique IP address assigned to this unit of App vShield. Please do not use an IP address that is assigned to another machine, including the VC, vShield Manager or any ESX host. Using an incorrect IP address you will need to uninstall and reinstall App vShield on this host. My question is: is it is absolutely impossible to install vShield manager on the same host ESXi as the vShield Manager resides?  Or is it just a bad practice?  What are the ramifications of installing?

  It is a general practice to separate management and resources. What you see is just a warning. When there are very fewer resources available you can do. Make sure that you exclude from the required VM by referring to this post

• Pairing of two VMS (always on the same host)

  
  I was wondering if you can marry two virtual machines together so that in the event of a host failure, they will stay together on the same host.

  You can create a rule to DRS for this (keep the virtual machines together). HA and DRS can complement eachother and in the event of a host failure, DRS will stay two VM together. For this purpose on the modification of your cluster settings part. See a screenshot here:

  

• vCenter Server and Manager on the same virtual machine and on the same host ESXi update that they manage

  Hi all

  I have a question to which I did not respond.

  I have an ESXi 5 on Proliant DL380 G7 server host. I want to install vCenter Server and Manager Update on one of the Server 2008 R2 VM on the same host. I know it's possible, but my question is how Update manager will provide updates to the same ESXi host it will run on? The update is applied every time host must spend in maintenance mode and power off the virtual computer running on this subject which means he'll kill VM where vCenter Server and Update Manager is running and the update will fail right?

  Is that possible at all or the VCS and UM such as a virtual computer operating point is updated to other guests if you have them or vMotion as VM to another host when you want to update the VCS and UM host is running?

  Thanks in advance.

  It will not work.  You will need at least two hosts.  This way you can vMotion the vCenter VM to another host.  From there, you can use VUM.  Otherwise, you will need to patch the host as a stand-alone host.

  See below for patching a standalone host

  Hello
  
  I have met many threads associated with this topic, but could not help meet me at good question, raising a fee.
  I'm setting up physical DB ensures for the first time. It is in the same host. Although I worked a little on the day before but did not get a chance to create new. I used the cold backup RMAN to restore the backup of the primary database. The version of DB is 11.2.0.3(32bit) and I create on Windows 7. The problem is that newspapers are not applied side sleep although I can find no error in the alerts log. Previously file associated password error was coming, but I solved that one.

  Transport is not executed on primary, because you log_archive dest parameter is not correct.
  Your problem here:

  log_archive_dest_2 string SERVICE=PRIMARY NOAFFIRM ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=STANDBY
  

  You must change it to:

  alter system set log_archive_dest_2 ='SERVICE=STANDBY NOAFFIRM ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=STANDBY';
  alter system set log_archive_dest_state_2=ENABLE;
  alter system  switch logfile;
  

  Change the setting and paste here the results, please.

   select process from  v$managed_standby where process like 'LNS%'; -- on primary
   select max(Sequence#)  from  v$archived_log; -- on both side

• Sqlnet.ora instance configuration when instances share the same host

  Hello
  
  According have modernized some of our databases to 11.2 which was on different machines on the same host again we realized that one of them had node valid control setting with the list of nodes invited in sqlnet.ora.
  
  Is it possible that we keep this configuration for the instance and keep others outside this configuration?

  Altan

  Laughing out loud

  And the use of valid_node and invited_node is fairly lame to start. I always wondered why implemented oracle implementation in their layer of sqlnet at all, being the right place to do the filtering on the router ip.

  So now you must be wondering why a single instance - and no others - used it in the first place. The solution to your dilemma will depend on the answer to this question. It could be that for a particular instance of filtering IP was valid. However, the decision to do so at the level of the layer of tns was wrong, and then pass that instance to a host with other bodies which have different requirements only aggravated the original error.

• server-side and client on the same form-side code

  I CFINPUT text on the form and the form displays the control on the form when I use the preview browser.

  As long as I have CF tag which is the code on the server side that have no controls on the form.

  I thinkg I missed something when I have both control code and the server of the client on the same form.

  I would like to know how I can show the controls on the form and the CF tag for code running on the server side.

  For example, I have a user name and password text box on the form.

  I need to validate the information user and need of a stored procedure that is executed when the user clicks on the "connect" button.

  I have 2 text boxes on the form and it works.

  As soon as I have the CFSTOREDPROC tag then the shape does not shows the controls.

  It seems the form to run sider server code, but client side of the code does not run.

  Your information and help is much appreciated,

  Kind regards

  Iccsi,

  The form action attribute points to a different file or the same file? If it is different then you can not see the controls because it refers to another file (action file). If this is the same file, then it might have a logic that prevents the form to display after the form submission.

  It would be useful to join the code. So, we could myself or others help you better.
