variable cluster shared doesn't work not as expected

Hi all

I use shared variables for communication between a computer host and target time real crio.  This works well as simple variables.  I configured a set of shared variables in an attempt to clean up the code a bit.

I have some problems.  If I write to a single element, for help, the other elements of the cluster that I don't want to not write to are replaced with unknown default values.   Second, when the host program is stopped, the cluster on the host computer RT wrote what appears to be default values for all variables of the cluster on the RT.  The idea is to keep the RTW program running in its current state until the host computer retrieves.  Of course, this is impossible, if it resets all default data.

It seems that I can only write to a cluster on one side and read on the other side.  I can't read/write in the same cluster at different points on the host machine and target.  With a shared variable, I can read/write to my hearts content on any process.  I could not find a way to solve this problem.

I'll post the code, but you will need a cRIO to run it.  If someone uses the cluster shared variables, I'd be curious to see how you do.

Thank you
John

That makes sense, I can think about is that you write on the same cluster in two different places. Each location will update the two values so if the host writes B1 = False and B2 = True then the Rio writes B1 = False and B2 = False, then the variable will be set to the most recent of the two being false. It's a loop condition.

Even if you only set a value in the bundle name the another value from the cluster to a package of entry by name.

To manage this, you'll need to remove the cluster to enter the bundle name and replace it with the shared variable read. This is where you need a time to make sure that the variable has the most recent value updated.

Also, you still have the stress points. For the shared variable try linking to the custom control instead of an indefinite cluster (choice according to below in the setup of the SV)

  • isLiteral function doesn't work not as expected

    We try to use "FILTER (isLiteral(?o))" to get all literal values for a variable particular sparql. It works for normal literal, but it does not work for CLOB values. If I have everything for the variable of the question, I get the following:

    O

    Given that the column "O$ RDFVTYP ' specifies 'BED' I assumed that this feature might work. The only option I see is to deny the Yaser function, but this can adversely affect performance. Are there other options?

    Thank you

    Hello

    This is the expected behavior. FILTER operations are not supported for long literals.

    Your idea to use the FILTER (! isURI(?o) &! isBlank(?o)) should give the expected results. Avoid a performance difference significant between the two approaches.

  • Linear in shape doesn't work not as expected?

    Hello

    I use the Fit.vi to NI_AALPro.lvlib:Linear on an array of vertically stacked points. However, the outcome makes absolutely no sense, the fitted line does not represent the input data.

    But if I rotate the points of 1 degree, adjustment seems to work...

    Why is this and is at - it a function or a way to properly adapt their orientation issues?

    Thanks in advance!

    I enclose:

  • Type check in Business Checks check list doesn't work not as expected

    Details of the environment

    ======================

    Disqualification Version: 12.1.3.0.0


    I defined in trade controls reference data the following configuration:

    Define by test of name checking:

    Type checking: check list

    Option 1: MOVE


    After that, I created a rule in the rules of reference data in accordance with the following:

    Rule ID: tstrule

    Apply to attribute: attribut1

    Check 1: define by test

    In the business rule processor, I traced attribute1 with the STATUS column. The STATUS column contains only the value either a SUCCESS or FAILURE .

    I expect all records with a value of pass to be in the list of records passing because PASS equals the value defined in the list, check however all records are appearing in the list of failure in the processor business.

    My understanding is that if you create a check and then use it directly in the rule as long as the check is satisfied (PASS = PASS), it must go through the processor business rule.

    Please indicate why the records are in a failed State.

    Note: I tried surrounding the value of Option 1 with single quote and double quote, but I got the same result.

    Hi Jason,

    Tested this case and it worked fine.

    You have all white spaces in the data or something?

    Or do you have other rules in the cheque which fail to record? You can see which rules are incorrect in the output.

    Kind regards

  • Bind 4 K doesn't work not as expected

    I started working more and more with 4K despite the material does not quite being height.

    We use CatDV on a 48 TB media server so that producers can annotate and select their clips. CatDV also creates proxies with the exact same file names that I can use for the first mounting with.

    When it comes to uprez, I take the offline sequence and choose bind again. I point the first proxy in the list on the clip of 4K and click OK. I would expect first auto add a link to the other items in the list to the new location/images but everything else in the list just goes back to be bound for the proxies. The only way I can get this process works as expected must temporarily rename the proxy folder, but which has the effect of disconnecting all sequences including bin clips.  So, after re-Binder the sequence to 4 K, I have to go out, rename the proxy folder to le nom d' origin and then go back and re - link all the clips of bin as well.

    This seems to be a very sloppy workflow.  Any suggestions out there on how to simplify?

    When PP is everything in the first folder, it will ask you for all other media not in this folder.  The project will not open until he found, or unless you have been told to keep that offline media.

    So if you see media offline after my listed operations, it may be only because you said PP to do.

    I don't know what you mean by 'bin clips.  All the clips are stored in lockers.

    Thanks for your suggestions.  I put a request for functionality with Adobe to explore the matter further.

  • EVC upgrade doesn't work not as expected


    So, I had my environment set to level to VShere 5.1 and improved my cluster of Merom VCA to Westmere the VCA above my two host systems are supported.  Then I started to reboot some of my less vital systems to put to level, but to my surprise, they all has not upgraded to Westmere.  Of the 7 systems that have restarted this day 1 has no upgrade at all and remained on Merom.  Two developed level to Nehalem and the rest went to Westmere.  Is it normal or I do not have something set up correctly?

    Power - off virtual machines, then in the settings of the virtual machine under Options - CPUID mask - advanced - reset default values. It must clear the existing settings from CPUID mask, and once power you the VMs on once again, they should apply the new EVC cluster mask.

  • Port group deletion doesn't work not as expected

    I have a project where I have to rename all exchanges (create new VM to move, delete old) for our new naming convention.  I have a script which covers this. However, he has a problem with exchanges that follow the new standard with the exception of its case.  The script removes the exchanges on the hosts where the portgroup is empty!  Is there a way to get around this?  I even tried to rename the old portgroup but same problem here because she sees 2 exchanges regardless of case and fails to rename.

    Example: The z is lower among the ancient and new.

    OldPG: VM_169.036.072.000_24_0134_BaSz_Data

    NewPG: VM_169.036.072.000_24_0134_BaSZ_Data

    $targetClu = "Cluster001".

    $fileLocation = "h:\pgChangeInput.csv".

    Write-Host ""

    $getPG = import-Csv $fileLocation

    Write-Host "step 1: create the new portgroup (s) on $targetClu"-ForegroundColor Magenta

    {foreach ($line in $getPG)

    $Clu = $line. Cluster

    $OldPG = $line. OldPG

    $NewPG = $line. NewPG

    $Vlan = $line. VLanID

    $vSwitch = $line.vSwitch

    If ($Clu - eq $targetClu) {}

    }

    }

    Any help is greatly appreciated.

    You're right, the vSphere client seems to check the case of an existing portgroup, while the New VirtualPortgroup don't.

    The AddPortgroup method also seems to be case sensitive.

    I couldn't find anything on this in the Documentation Centre of vSphere, but in the book of vSphere Mastering of Scott Lowe, he also says that the names are case-sensitive.

    But it seems that PowerCLI is correctly using the name, which is case-sensitive.

    Back to the problem of you, you can use an operator that is case-sensitive in a Where clause to filter the desired portgroup.

    Something like that

    Get-VMHost $esx |
    Get-VirtualSwitch -Name $vSwitch |
    Get-VirtualPortGroup -name $OldPG |
    where {$_.Name -ceq $OldPG} | Remove-VirtualPortGroup -Confirm:$false | Out-Null
    

    Note that it uses the ceq- instead of the operator -eq .

  • Apply source formatting doesn't work not as expected

    Hello!

    I currently have a very simple problem, but it's annoying for me.

    The option 'Apply source format' has stopped working for me. I mean, it works, but not entirely.

    For example, I set my preferences for the tag "div" like this:

    before line breaks, inside, after. Content formatted and indented.

    But here is the result when I try to apply:

    < div id = 'page-wrapper' >

    < div class = "container-fluid" >

    < div class = "row" >

    < div class = "col-lg-12" >

    < h1 class = "page-header" > projects and customers < / h1 >

    < / div >

    < / div >

    < / div >

    < / div >

    It is really strange. It seems to work on half of the div only.

    Can someone help me with this?

    Thank you!

    It could just be a glitch of Friday the 13th.  For what it's worth, I created a keyboard shortcut to apply shaped Source (Ctrl + Q).  It saves time and I'm not click on the wrong item by mistake.

    This behavior is caused by the white dots on the right side of the page master, forcing the content area (and thus the scroll in the browser area) is much wider than what you want.

  • WkStation 7 - Snapshots doesn't work not as expected

    I am new to Workstation 7 and the ability to create multiple snapshots. In the end, I want to have a parent with more children - every child

    running a different version of MS Office.   However, in trying to do so, I am having instant strange behavior that left me speechless.  I googled and searched the forums and didn't have not seen anyone with a similar problem arise.

    I don't know what, if anything I am doing wrong.  I am running the latest version of Workstation 7 (7.0.1 Build 227600) on a host Windows 7 Ultimate.  Here's what happens:

    1. I created an installation fresh comments from XP Pro w / SP3 and all updates of Windows from May 22, 2010.

    2. I took a snapshot of this new facility using Snapshot Manager with the closure of XP Pro VM.  I named this snapshot 'PARENT - PRINTER' and then before him and correctly installed my network printer.  I can print to the printer.  Life is good.

    3. I then stop the machine virtual and made a new capture instant I named 'CHILD 1 - OFFICE 95'.  I then started "The CHILD 1 - OFFICE 95" snapshot and installed MS Office 95.  I rebooted and everything tested.  Is my network printer, I can print to it and all my Office 95 applications work.  Life is always good.

    4. I then stop the virtual machine and use Snapshot Manager to highlight the snapshot called "PARENT - PRINTER" and selected "go to."

    5. I then made a third called 'CHILD 2 - OFFICE 97' and starting the virtual machine snapshot.  Here is where the unexpected happens...

    -The first thing I noticed when the "CHILD 2 - OFFICE 97" started snapshot was that my network printer has been installed is no longer (the driver folder and everything's gone - for what is the virtual machine's printer was never installed)»»

    -The next thing I did was arrested and use the Snapshot Manager to ' go to ' snapshot 'PARENT - PRINTER '.  At the start of the snapshot 'PARENT - PRINTER', my network printer has been installed is no longer.  This left me very puzzled because it comes from the mother.  How the parent did get corrupted?

    -I then stop and used Snapshot Manager to ' go to ' snapshot 'CHILD 1 - OFFICE 95 ".  When I started this snapshot, my network printer has been installed but Office 95 was installed is no longer.

    It is repeatable - I tried it 3 times.    I'm doing something wrong?  Am I misunderstood how Snapshots should work?  Or is there a problem with my computer?  Curious minds want to know...

    Any idea / advice is appreciated and welcome.  Now, I find myself scratching my head.

    When you take a snapshot, it's a snapshot of the current configuration with the configuration.

    You must take the snapshot after installing drivers and applications!

    In your case it means that:

    1. Install the operating system and patches

    2. Take a snapshot named "Base - operating system installed"

  • Install printer drivers

  • Take a snapshot named "Parent-printers installed.

  • Install Office 95

  • Take a snapshot named 'Child 1 - Office 95 installed'

  • "Instant Goto" printers installed.

  • Install Office 97

  • Take a snapshot named "Child 2 - Office 97 installed"

  • I recommend you to take snapshots when the virtual machine is turned off.

  • Table 1 d of resizing doesn't work not as expected

    I try to resize a table 1dimensional in Teststand via AvtiveX using SetNumElements() with weight 0x00.

    I don't know what is happening here, but your steps really do that properly in all cases. Try this.

    (1) make your selection, you see the moving dotted line

    2) click on the layer mask icon in the indicated measure. Note the mask is shown on layer 0

    (3) on the screen, it will look like this with a transparent background, but nothing has been deleted

    (4) If you are not comfortable with being there layer mask, select the mask and right click then choose apply layer mask. I would say it's totally useless, but some people find it easier to understand.

    (5) the layer will look like below. I know its tempting to cut and paste, but ultimately you lose things, but to do this way, you are in complete control and can go back if you make a mistake.
