Script to activate the memory add Hot

Hi all

I'm working on a script enable hot-memory add for all of the virtual machine in the environment. Here's what I have so far:

# The vCenter connection #.

$a= Read-Host "Please enter the name of the Virtualcenter: '

SE connect-VIServer

Connect-VIserver-Server '$a' -credential (Get-Credential)

# Function to allow hot-memory add #.

Int Enable-MemHotAdd()$vm) { }

$vmview = Get-vm $vm | Get-View

$vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec

$extra = New-Object VMware.Vim.optionvalue

$extra . Key='mem.hotadd'

$extra . Value="true"

$vmConfigSpec .extraconfig += $extra

$vmview . ReconfigVM ($vmConfigSpec)

}

Get-Host | Get-VM : enable-memhotadd

# Disconnect vcenter after configuration #.

disconnect-viserver -confirm:$false

I'm not 100% sure on how to get the function to run several times. I found the function online, I think it's good. Is there a better way to do it? I better do it by clusters or do I just do it on all the virtual machines in the vCenter lvl? Am I close?

What do you think guys?

Thank you!

You should be able to do something like this (instead of Get-Host |) Get - VM: enable-memhotadd) :

$vms = get - VM

{foreach ($vm to $vms)

Enable-MemHotAdd ($vm)

}

This allow for all the virtual machine in your vCenter, keep in mind that it can take some time if you have a large number of virtual machines.

  • No matter what script to enable the Add - in Essbase Excel?

    Guys,

    Someone at - it a script to enable the Add - in Essbase Excel. I'm looking for something more on the lines of VBA, VBScript.
    The reason is, we have installed Add-in Essbase in several citrix servers and whenever the user starts Excel of the new citrix server, the user must enable it.

    Thank you
    PM

    If you are using vb script, you can use the following text:

    '---------------------------------------------------------------------------------
    ' Step 3. Activate the Essbase Excel add-ins

    Set myAddIn = XL. AddIns.Add("C:\Hyperion\Essbase\Bin\essexcln.xll")

    myAddIn.Installed = False
    myAddIn.Installed = True

    -------

    You have to find the equivalent of the above in excel vba.
    And also the location of the essexcln.xll.

    With citrix, I guess the problem is with the user profile under

  • Not possible to activate the scripts on the Web server

    Hello

    I would like to create a page .html for Web with a bit of scripting ESP included - Services because now I understand just this:

    <% for (i=0; i<3; i++) {
      ...some text...
     } %>

    According to this document NOR, I first need to enable scripting:

    To use the script with a Web service, you must enable the feature on the Web of LabVIEW server. In LabVIEW, select the script on the Web Server: Configuration page in the dialog box Options to enable the use of scripts on the Web server.

    I activated the Web server and it works OK. But there is nothing called "Scripting" in the configuration page - and the script is executed (the code is just printed in the form of simple text).

    Anyone know how to activate the ESP script?

    Version: LV 2012.

    Best regards, Jan

    Hi Jan,

    In fact, you use the ESP file instead of a static HTML file.  For example, if we had the static html file:

    Hello world

    This file can be located at something like /MyWebService/HelloWorld.html.

    If I then do something like have a page to say "Hello, Jan" or "Hello, Mark" I could use ESP.  In this case, your code might look like:

    <>

    var xname = form ['name'];

    %>

    Hello, @@xname

    The URL of such a web method is perhaps something like jan/MyWebService/Hellovar/Jan where Jan string literal passed to the terminal of a web method that can resemble

    In this example, the string "Jan" is passed to the terminal of the value of the VI.  What implementation of the Web method in the spec to build his signature might look like in /Hellovar /: value.

    So, back to your original question.  You embed not ESP breast and the HTML document.  Instead, you embed HTML inside a document of ESP and the rendering of the document in HTML format when accessing the URL of the Web method.  While the paper you mentioned earlier has an example project in that you can use as a reference

  • How can I find the memory just to add to my computer?

    I have a HP Pavilion a1642x dektop PC.  My operating system I have Windows XP.  Maximum capacity is 4 GB.  Installed memory is 1 GB (2 modules of 512 MB).  I searched on the site of HP for the same number of DIMM DDR part I have in my PC but I can't.  The PC is six years old.  Is there a new part number and where I can get it?

    I have a few other questions.  My Information System says:

    Maximum capacity is 4.00 GB

    Installed memory is 1.00 GB

    Has memory 1 GB 512,00

    Location 2 has 512,00 GB

    There are 4 locations in memory, but memory modules are not physically installed in adjacent locations.  My uneducated eyes, looks like they are installed in the Sockets 1 and 3.  But the HP Ugrade and and maintenance Guide says that when adding memory, install the new module in the closest the pre-installed module making.  Then I noticed that 1 and 3 are in blue and 2 and 4 is black.  What is bring her to this?  What is one thing bank address?

    I would spend at least 2 GB of memory.  Everything you need to install two new modules of 512 MB.  Right?  What are my options if I want to move to 4 GB?

    Sleepless

    Hello:

    You were right to assume that the memory is installed in the banks of colors.

    This is because memory will operate in DDR mode this way rather than the CSD mode.

    What I would do if I were you, would be to buy 2 x 1 GB of memory and add it in the empty slots and you will have 3 GB of memory.

    If you remove these two 512 circuits and replace those with 2 x 1 GB modules, your BIOS will recognize all the 4 GB but windows will probably recognize only 3.1 to 3.7 GB depending on what hardware is installed in your PC.

    You need an operating system to 64-bit for all 4 GB of memory to be seen and used by Windows.

    Another thing, you might want as your PC can take up to 8 GB memory (4 x 2 GB) with a 64-bit operating system, just buy 2 x 2 GB memory PC2-6400, and although it will not be used, if you ever decide to move to a 64-bit operating system, you will have 5 GB memory ready and waiting.

    http://support.HP.com/us-en/document/c00787158

    Just a thought.

    I run the analysis of Crucial memory tool and let the report type and the amount of memory to install.

    You can buy them or elsewhere. The nice thing about Crucial is that they guarantee compatibility.

  • Customize the game memory - add your comments on match

    Hello

    I am writing to see if there is a way to customize the memory game, interaction of training.  Know, I would like to be able to provide feedback to the user when a match is found.

    So:

    • 1 card reversed
    • the 2nd card is a game
    • display a text box to the user of the comments on the match
    • Click on the button continue with the game.

    Is it possible to customize the interaction of training to do this, or that I have to build something like Lilybiri very cool game of Concentration of Custom?

    I must say I'm quite new to advanced Actions and I am running 9.0 Captivate.

    Thank you very much in advance for your help!

    Leigh

    Hi Leigh,

    Thanks for your comment on my old blog. Play training interactions are customizable, but only in their design. Other interactions of training have still less possibilitiy of customization. Provide feedback to a game is not included, have to disappoint you.

    Creation of such a game with Captivate 9 would be much easier than with older versions for which I wrote the blog post. This kind of 'Advanced' use of actions in Captivate will certainly appear in the cookbook for the actions that I am writing right now. It's supposed to be a warning, first of all try to get out to cling to variables and advances of shared actions. Don't forget the new multistate objects! Adds other measures that this allows a lot more Captivate with less time developing.

  • How to re - activate the FF 29 Add-on compatibility check

    Several weeks ago, I installed FF 29.0.1 on two virtually identical XP systems. I have been carefully maintain extensions, settings, etc., in parallel on both systems.

    Initially, my main system told me if an extension in my search list was incompatible with 29.0.1, and no doubt, that's what I want to do.

    However, I recently installed a couple of extensions, which seemed to work very well. (I had downloaded installers and then installed in the files.) Then, when I tried to install from the same files on the second system, he told me that they were incompatible with 29.0.1, and that they could not be installed.

    I would like to re - activate the verification of the compatibility of the system on which it seems to have been turned off. I tried FF forums at length, but may not know all the information about: config or other settings may have an impact on this.

    The error message that I get on a system when trying to install some extensions is a small box of drop-down menu of green extensions Manager icon near the top left corner of the screen. However, it disappears when you press the 'Print screen' key and does not appear in the captured image. I noticed this kind of weird on some other sites. So, it seems impossible to get a picture of the message. The message may be re-displayed, but not printed, by clicking on the green icon. However, the text of the message, ' < name of the extension - > could not be installed because it is not compatible with Firefox 29.0.1.» Note: It is easy to reproduce this message, temporarily turning on extensions.strictCompatibility and tries to install older extensions.

    In any case, the system on which I was getting the message now behaves identical to my other system, apparently without any change of parameters. Therefore, I believe that it was a persistent but temporary problem that may have been fixed by a reboot. Therefore, the problem seems to be resolved.
