Call a Python Script from vRO

What is the appropriately and cleanest way to call a vRO Python script?

However, if I can do my integration with only a single external system to interface with, why use 2?

It's really a compromise do you: what happens if your network breaks vs what happens if your vco breaks. which of the two is more likely and which will be worse as a result.

Using an external script host cut you your execution environment of your control environment. While this is to introduce certain dependencies - such a network availability -'s done it for good reasons. You don't want a malicious script to make your broken control environment. You want to separate and isolate the script execution environment so that any errors that might occur during the execution of the work does not affect another system or system component. That's why we do virtualization in the end. Otherwise, we would all run that on a bunch of linux hosts.

Think about it you can really get orchestrator as sort of an hypervisor for your work runs: he has a script interpreter base (javascript) that will allow you to control what you want to do, but is quite isolated, when it comes to operations the-> real<- hardware="" where="" vco="" runs="" on,="" so="" it="" isolates="" execution="" from="" control.="" just="" like="" esxi="" has="" some="" operating="" system="" but="" hides="" everything="" that="" would="" make="" it="" possible="" for="" vms="" to="" have="" any="" inpact="" on="" other="">

Also, you want to be a cheap and replaceable component that not to really care about the POS host. The extra effort (like any method of cluster), you invest to protect your central components - for example, your host orchestrator - is probably oversized for your work-executors. Executing script host dies? Who cares, roll the workflow for the deployment of a new automated and be happy again. In large environments (~ 2000 guests), it is quite normal that you have 10 + host failures - one day! There is nothing that you can control, is that the sum of MBF components. You should therefore not care how resilient your infrastructure - because it is not the case - but how to cancel your services are.

Thus, when it comes down to 'break your vCO because of scripts run on your vCO host' versus 'lose a host of completely replaceable script' I would always choose the script host to run my jobs.

  • Call script from a file of commands PowerCLI

    Hi all

    I'm fairly new to using PowerCLI, but have already seen the benefits of its use to manage and administer a large infrastructure, we have about 50 guests with esx4i, and it has been very helpful.  I have a problem, but trying to run a health check, I want to create a batch file that calls a .ps1 script and then plan its like a task...  However, here is the batch file code:

    C:\WINDOWS\system32\windowspowershell\v1.0\powershell.exe - PSConsoleFile "C:\Program Files\VMware\Infrastructure\vSphere PowerCLI\vim.psc1" - command '& {c:\scripts\myscript.ps1} '.

    It comes up with this in the cmd prompt after executing the batch file:

    Please specify a name server of VI, for example...
    PowerShell.exe vCheck.ps1 MyvCenter

    However, I have Connect-Viserver connection code in the myscript.ps1... The script runs a lot of PowerCLI, anyone know what Miss me?  Thanks for your help... any input would be appreciated.

    Chris

    I'm not much of a PowerCLI person, but you don't have to create a batch file.  Just paste the line of text below in your scheduled task Windows OS.  We usually define the run as: with an account that has rights to vCenter.  Also, make sure that the box run only if connected is not checked.

    C:\WINDOWS\system32\windowspowershell\v1.0\powershell.exe -PSConsoleFile  "C:\Program Files\VMware\Infrastructure\vSphere PowerCLI\vim.psc1"  -command "&{c:\scripts\myscript.ps1}"
    
  • Call .seq Python files

    I'm trying to use Python to call a .seq file, wait until the sequence is done, and then resume the Python script.  I got everything to work it seems however my problem is when I make the Engine.NewExecution seems not to run the movie file and WaitForEndEx to expire. (Time for my movie file is about 50 seconds).

    What I am doing wrong?

    Python code:

    testStandEngine = win32com.client.Dispatch ("TestStand.Engine.1")
    sequenceFileObject = testStandEngine.GetSequenceFileEx ("C:\\...\\SIL Version .13\\Teststand Primitives\\ShutDown Target.seq")
    testStandExecution = testStandEngine.NewExecution (sequenceFileObject, "MainSequence", sequenceFileObject, False, 0)
    testStandExecution.WaitForEndEx (60000)

    Hobbs,

    I am able to call a movie file and get the behavior you expect with the files I enclose you.

    The code is basically the same code that you have, and I just added additional logic to determine the path of the file in sequence automatically (to the zip file so that you can run it) and I removed the client file of sequence setting just so I can see if the sequence is running without the important process templates.

    I've built and run with Python 2.7.1 using win32com 7 February 2012 (I wasn't able to determine where they store the version)

    Hope this helps,

  • Conversion of scripts from one domain to another

    Back to the pre OpenScript versions (v8), there used to be a utility (under the Tools menu) to convert the scripts. This would be useful for example when migrating a script from one environment to another (for a script can be used in a production environment?) However, this feature is not currently available in recent versions.

    I realize, you can try to do a global find/replace in the Java code, but it doesn't seem to be as simple as replacing the root of the URL like this leaves the issues with dynamic variables is most recognized (I get losts of messages "Could not be resolved" if I try this exercise).

    Is there a simple way to edit a script of 'https://URLA/application' to 'http://URLB/application '?

    NOTE: In the example above I also changed from HTTPS to HTTP simple.

    In 9.2 under Tools, there is an option called URL set... You select this option and it will display the URL of the application and a text field where you can enter a variable name. Then you can select all instances of this URL and OpenScript will be replaced by the variable. Once done you will have code such as

    Initialize the Section
    getVariables () .set ("bilbobaggins", "http://www.scl.com",
    Variables.Scope.GLOBAL);

    and in the running section you would have something like

    Web.Window (2, "/ web: window [@index = '0' or @title =' about: blank']")
    . Navigate (' {{bilbobaggins, http://www.scl.com}} / OA_HTML/RF.jsp "" ");
    Web.Window (4, "/ web:window[@index='0" or @title = 'Login'] "")
    .waitForPage (null);

    Notice it will return the variable and also have the saved value. So if you want to play against another environment just to change the value of the variable and replay.

    Hope this helps

  • When I run my script from a shortcut ExtendScript is invoked, but this isn't when I run the menu

    I use Photshop CS2 on Win XP

    I set up a keyboard shortcut (Ctrl + Alt + P) to execute a .jsx file in the folder... \Presets\Scripts\.

    When I activate the script via the keyboard shortcut ExtendScript is called and interrupts execution on main() statement (see below).

    When I activate the script via the menu file/Scripts that extendscript is not called and the script runs up to the end.

    The .jsx file is a wrapper for a .vbs script that does the 'real' work

    The .jsx is:-

    main() function
    {
    var VBSscript = file ("C:/Program Files/Adobe/Adobe Photoshop CS2/Presets/Scripts/GGN_PS_Code_v1_2.vbs");
    If (VBSscript.Exists) VBSscript.execute ();
    }
    main();

    Anyone have any ideas on how to disable the invocation of ExtendScript when I run the script from the skortcut?

    One thing to check is that the .jsx extension is associated with Photoshop and not ExtendScript.

  • Call of action/script...is it is possible to determine?

    I wonder if it is possible to determine in a script which is the component script or action.

    Example: Suppose I have Action 1 and Action 2 both call the same script. For Action 1, I prefer the script to do a thing in Action 2, I would have preferred something slightly different. Is it possible for the script to know that 1 Action active?

    Ditto for when a script calls another script. Without the caller script set anything external that reads the script called, the called script cannot know what active script?

    Take a look at .stack $. The last line must contain the name of the script the highest level.

    As for stocks, you can't say what actions a script was called from. I suggest scripting wrapper for stocks. Put the name of the action in the name of the script and have it include the actual script. Create one per share. You can then use the trick of .stack $ to guess what action was the appellant.

  • Unable to wait 30 seconds and then call the TCL Script as Action?

    Hello and good afternoon all!

    I was browsing through different threads and did some research and I am unable to get my applet to wait 30 seconds and then call a script TCL to a succession of 'action '.  Here is the Basic script I am trying to run:

    Event Manager applet track-loopback1
    Event track 10 down state
    command action 1.0 cli 'enable '.
    Action 1.1, «config t» cli command
    Action 1.3 cli command "event manager applet-counting backwards.
    action 1.4 cli command 'event timer countdown 30 '.
    action 1.5 cli command "action 1.0 wait 30.
    Action 1.6 cli command "end".
    Action 1.7 cli command "tclsh Loopback1 - Notification.tcl.

    The goal of this applet is simply wait interface Loopback1 go down, and then launch the applet "-Countdown ' which waits 60 seconds before calling end my TCL script.  The pattern of ' countdown time 30 "and the" action 1.0 wait 30 "is my (lack of?".  :-)) understand that after counting 30 I need to a trial of the action - but I'm not 100% clear on this?  Ironically, he does, in fact, call the TCL script, it does not wait 30 seconds.  My current workaround is to simply throw a statement "after 30000' in the TCL script, but I'm really curious to know why it does not work as expected (well, as I expected to work anyway!).  Any help would be GREATLY appreciated.  Thank you very much!

    See you soon,.

  • Best way to run a script from a script

    Hello world

    I'm looking for running a script from an After Effects script, so far, there is aftereffects.executeScript (scriptContent) who use eval to run the script. The problem is that it uses eval so it is not really sure and he is slower. So I would like to know what is actually used when we file-> Script-> Run script file.

    As seen in the Javascript tool Guide CC page 168 in the section QAnywhere Corss-DOM.

    aftereffects.executeScript(theScriptContent); // Doesn't work with a script which as comments AND the script has access to my scope
    

    In addition, if there are comments like / * * / or / * / in the script I want to run, it no longer works.

    So, what is the best way to run a script from a script?

    If you want to evaluate a whole script file, you can use $.evalFile (file, timeout) - see description in ESTK object model viewer

    To evaluate a bit of code, you can use eval, that's for sure.

  • Executing a dynamic script from SQLPLUS name?

    I have a script that will run in SQLPLUS.

    I need the script to query a table and assign the result value to a variable.  Then I have to call a second script showing the value of this variable.

    Here is an example of generic non-what I need to do.  I need to insert a value into the variable "scriptname" can run the script with this name.  Is this possible?  By the way the value of a file beats or something is not possible in this situation.

    DECLARE ScriptName VARCHAR2 (50);

    BEGIN

    -Get the name of the script

    SELECT NextScript IN GenericTable ScriptName;

    -Run the script

    @ScriptName

    END;

    /

    Not really possible.

    All PL/SQL code will be submitted to the database must be performed, so that the database can not run scripts back on the client SQL * more tool, as the control is not returned to SQL * more until that code PL/SQL completed.

    If the scripts are on the server, then you might have a PL/SQL code that loops through the script names and submits the work to be performed immediately using DBMS_SCHEDULER, he call sqlplus command line with the relevant script / etc paths, but if your going to go to all that trouble It would be easier to put scripts in packages/procedures etc. PL/SQL code and just call those that you need.
