move the cluster for sub vi

Hello

I want to spend a cluster that can change its content to one under VI. The cluster does not change by program, but during programming, that is, I could add or remove items in the / cluster. Using direct wire or local variables I would have to change each sub VI that uses the cluster updated the. I also tried the typedefs, but I met the same problem.

At the same time the Subvi should be able to update the cluster I spent.

In C++, I use classes like struct (equivalent to the cluster of LV) and pass a pointer to a class object to a function. Within the function, I choose the members of the class I want to use inside this function. If I change the class structure, the functions of the Word are not affected (of couse only as long that I remove irrelevant of class members of the called function).

Example (from C++):

settings * param;  'settings' is a class that I use to group variables

doSomethingUseful (param);

/ * the doSomethingUseful function uses the pointer to parameter and accesses the members of

Param-> variable1

Param-> variable2

...

Hereby, I can change the values of variables stored in the param object

*/

Best,

Max

  • Move the Cluster VMs of inventory to turn off

    Hello

    I have a list of VMS to downgrade from a CSV file.

    What I want is to be in the script to read the list the files and move virtual machines from one CLUSTER to the 'DOWNGRADING' folder within the VCENTER inventory.

    The following PowerCLI script will change all VM file VMs.csv in the DECOMMISION folder. The script assumes that the VMs.csv file contains a header with VM as column header row. Also the script can only move the virtual machine to a blue folder in the hierarchy of vCenter.

    $Folder = Get-Folder -Name DECOMMISSION
    Import-Csv -Path VMs.csv |
    ForEach-Object {
      Move-VM -VM $_.VM -Destination $Folder

  • What is the best way to move the node for virtual device to an IDE SCSI hard drive?

    I used PowerCLI on vSphere 5.0 5.5.

    I'm deploying VMDK that were created with a switch in Ghost from Symantec, which by default is the HDD to IDE interface.  How can I change the HD of IDE, SCSI using PowerCLI?

    We also seek to regenerate the VMDK with the correct setting in Ghost, but maybe it's not feasible.

    I looked at the post below, which seems close, but don't tell me how to change the Type as the disk ID number.

    Sort of put the virtual device node / drive SCSI ID?

    When I look at the vmdk on the host for the virtual machine, I can see that the ddb.adapterType field is set to "ide" and KB 1016192 - conversion of an IDE virtual disk to a virtual SCSI disk

    http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1016192

    I need to have the value of "free", but I can't manually change the vmdk file.

    In addition, the hard drive has the VM operating system already installed on it, so I don't want to just remove it.

    Another related problem is that I can not put the type of SCSi LSI Logic SAS controller LSI Logic parallel (Windows VMs does not start if it has the value LSI Logic SAS). I just get an error "inconsistent backup specified for device 0.

    Appreciate any ideas.

    I thought that I would come back and update this post.  I got it works by changing a setting when I create the VMDK.

    I changed the way I created the VMDK via the Symantec ghost32.exe (version 11.5?) application by adding the following switch:

    -vmdkAdapter = free

    Ghost32-clone, mode = restoration, src = 'SRC %', dst = "% DEST" - vmdkAdapter free course =

    It worked for my Windows 2008 VMDK, don't know what he'll do for any other type.

    At the end of the day, I have never able to edit the VMX of PowerCLI file, although I got close enough.

    Regarding PowerCLI, I think I have corrupted files on the ESXi server and could never get around it. The steps were roughly as follows

    1. the Copy-DatastoreItem cmdlet to copy the file vm.vmx on the desktop of the local computer

    "2 use Get-Content to read file and change ddb.adapterType ="ide"with ddb.adapterType. =" free ".

    3. copy a ConvertTo-LinuxLineEnding cmdlet from the internet and remove CR/LF characters to the BYTE level; because nothing else has worked.  I still don't think it worked 100%.

    4 copy-DatastoreItem to copy the vmx file to the directory of the virtual machine.

    The vmx file has the correct setting and looks ok, but I think something is broken here, because when I use the VI Client to look at the data store, there are only 2 files in the directory. I don't know which more.

    5 remove-hard drive

    6 New-hard drive - vm $vmObj - diskpath "[datastoreName] vm/vm.vmdk", at this point, I get "the path of the specified disc is inaccessible or does not exist.  It is probably because I have damaged the structure of files on the data store.

    When I delete the virtual computer in the VI Client, I can remove it with success, but I have to manually delete the directory on the data store using skip
    Control data store.

  • How to move the vm for VMware Server ESXi

    I have a host with ESXi 3.5 and I want to move virtual machines to a different machine with VMware Server 2.

    You can use VMware Converter (free copy).  When you install it convert you a machine and select the Virtual Machine of VMware Infrastructure as the virtual source then Machince as destination.

  • Error after you move the request for new development machine (minimum environmental change)

    I'm really new FAD and work on my first application.  So far it's going pretty well, and I'll have a blast.

    I met a problem move on my application to a new machine however.  I initially developed on the virtual machine running on my laptop, but decided to switch to a more powerful machine.

    I have a problem trying to 'Run' of pages in my application.  Integratedweblogic is throwing an error everytime I try to load a page (and only the web pages window session that opens just shows 'o' turning indefinitely):

    "DFW-99998 [javax.naming.NameNotFoundException] [oracle.jbo.server.DBTransactionImpl.lookupDataSource] [j2ee app]".

    Original environment:

    Windows 7

    Oracle JDeveloper 11g

    Oracle DB for windows running on the same OS/env/localhost

    New environment:

    Windows 7

    Oracle JDeveloper 11 g (same version)

    Oracle DB running in a vm virtualbox using Oracle Linux (it is a much larger, more 'production-like', a database in which my application would be hypothetically).

    I made the necessary changes to the connection of database (host/port/user/pw/etc) used by the app and I still get the above error.  I even tried to copy across my jdeveloper and integrated settings of the server weblogic (C:\users\me\AppData\Roaming\JDeveloper\system11.1.1.7.40.64.93) to the new environment in addition to the copy in the root directory of the application, change the db connection settings, and I still get the same error.  I also have the same error occur when, after having made the connection Exchange Pb, delete the weblogic (C:\users\me\AppData\Roaming\JDeveloper\system11.1.1.7.40.64.93\DefaultDomain) server folder and start again, with jdeveloper build a new instance IWLS run.

    I must point out that, when I run the app service module in the new environment with the db connection changes, I can test all Instances of the view object, and they work as before and as expected in the Oracle Business Component Browser window.  So that seems to indicate that it's just a problem with my setup of weblogic/instance, but I'm not sure.

    As always, I appreciate very much all your comments and thanks in advance for answers!

    If you like the framework automatically adds the data source, it must be checked. If you want better control and better together for manufacturing sheet you it is unchecked. In this case you must create the data source on the web logical server yourself.

    Try again with the box checked initially.

  • Move the object for a certain interval of time

    Hello, I am working on a tile set based, and currently I'm trying to fix the movement. I want to make is that my character moves easily for a fixed amount of time. I could not be explaining my self very clearly, but I want to do something like this:

    function keyPress(event:KeyboardEvent)

    {

    If (event.keyCode is Keyboard.RIGHT)

    {

    Moves 25 characters pixels to the right smoothly.

    }

    }

    Hope I did understand, any help is much appreciated

    Here's a way to move a key maintained, but it will not help if someone starts to sting the key since you have a timed speed movement.  To overcome that you'd have to have a listener for the interpolation, which contains a similar restriction / control...

    var rightDown:Boolean = false;

    stage.addEventListener (KeyboardEvent.KEY_DOWN, keyPress);
    stage.addEventListener (KeyboardEvent.KEY_UP, keyRelease);

    function keyPress(event:KeyboardEvent)
    {
    If (event.keyCode is Keyboard.RIGHT)
    {
    if(!rightDown) {/ / only allow the interpolation occurs when the key is pressed first}
    rightDown = true;
    Tween here

    }
    }
    }

    function keyRelease(event:KeyboardEvent)
    {

    reset the command when the key is released
    If (event.keyCode is Keyboard.RIGHT)
    {
    rightDown = false;
    }
    }

  • Can I use webcam only move the cover for - and backwards

    I have a laptop Toshiba Satelite. The Chicony webcam has been in place for some time now.
    It turns off when the system is moved.
    I can usually get working again if I slightly tilt the screen forward and backward.

    It would be a driver problem or a certain type of loose connection?

    Hello

    I doubt that it is a driver of webcam problem.
    As far as I know, the webcam is connected to a USB controller on the motherboard.
    Maybe there is loose connection or contact and therefore the webcam disconnects and does not work properly.

  • Move the database for VirtualCenter of SQL Express to SQL 2008 on another server

    Hi all

    First of all, I spent some time trying to figure how to move our current VirtualCenter database to our production (currently the DB is stored on the server using SQL Express real VirtualCenter) SQL server. Before any way suggests the obvious, I searched the VMware knowledge base and tried to follow the steps in the following KB:

    http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 7960893

    I have successfully completed the first 2 steps, but when I see the data source in the ODBC Administrator, I don't see anything (I have connected with each account who has already logged on to this server just in case). To work around this problem, I tried everything simply create a new DSN pointing to the new SQL Server. I even modified registry settings in order to force him to watch the new SQL Server. Despite this, I can not start the VirtualCenter service because it does not connect to the new database. When I reinstall the database local, everything is good.

    I did much research on similar questions, but not once I saw someone mention that no data source was present. I don't know if this was due to an option selected during initial installation or anything else.

    We are currently running version 4.0.0 vCenter. Any help would be amazing!

    Thanks in advance

    Dean

    Is your operating system 64 bit or 32 bit - because it affects the DSN, you see:

    To work around this problem, use the appropriate version of the ODBC Administrator tool. If you build and then run an application as a 32-bit application on a 64 bit system, you must create the ODBC data source using the ODBC Administrator in % windir%\SysWOW64\odbcad32.exe. To indicate the type of DSN, you can add '_32' to the user 32-bit DSN and "_64" to the 64-bit DSN user.

  • Write to the Cluster size in binary files

    I have a group of data, I am writing to you in a file (all different types of numeric values) and some paintings of U8. I write the cluster to the binary file with a size of array prepend, set to false. However, it seems that there are a few additional data included (probably so LabVIEW can unflatten on a cluster). I have proven by dissociation each item and type casting of each, then get the lengths of chain for individual items and summing all. The result is the correct number of bytes. But, if I flattened the cluster for string and get this length, it is largest of 48 bytes and corresponds to the size of the file. Am I correct assuming that LabVIEW is the addition of the additional metadata for unflattening the binary file on a cluster and is it possible to get LabVIEW to not do that?

    Really, I would rather not have to write all the elements of the cluster of 30 individually. Another application is reading this and he expects the data without any extra bytes.

    At this neglected in context-sensitive help:

    Tables and chains in types of hierarchical data such as clusters always include information on the size.

    Well, it's a pain.

  • Space in the name of the cluster

    Hi all

    I have an obligation to give a space in the name of the cluster, for example 'server '.
    Coherence supports space in the name of the cluster. I know, he can't stand point.
    and if he can't then how?
    for dot, we replaced with underscore in our api.
    Let me know what you.

    Thank you
    Vinay

    Vinay,

    Who told you this Cluster name can not contain spaces? I did the test on 3.5.3 - p8 which allowed areas and points. The developer for 3.5.3 and 3.6 guides say not that you can not use spaces or points.

  • Which cluster for the placement of DLR control VM?

    Intend to have 3 groups for a design of the NSX - calculation, cluster management (Infrastructure) and Edge? Cluster Edge willl have GSE and controllers.

    Who is the cluster recommended to place the DLR VM control, and what design considerations should be made?

    Thank you

    Ousmane

    The implementation of cluster is pretty much arbitrary as long as you have sufficient resources and groups necessary distributed port.  It would be wise to keep control of the DLR VM with the edges because it is a type of edge... Or it might be a good idea to move your DLR and the cluster in your cluster of right management controller, based on the logic function... that way the edge gateway data plane loads haveore has dedicated resources.

    With the placement of the bunch, his main concern should be the availability of resources to workloads in the cluster.  Secondarily, may give priority to the proximity of heavy workloads related? Other considerations are really just aesthetics.

    It is perhaps a good idea to examine the way which you cut the clusters.  What was your purpose behind this structure? Who is?
