Read Only OMI application

Trym Synnevag

What is the de-facto best practice for providing operators with a read-only OMI application?
Should this be done by deploying a separate server with read-only licenses, or is it acceptable to configure read-only access on the same terminal server?
Additionally, is there a straightforward way to achieve read-only access when using OMI Web?

Assume there is a read/write OMI application already running. 

Also, is this practice the same for InTouch?

    For OMI Desktop Application the method of using reserved licenses for Read Only is one valid option, but in scenarios where you need more control you can use the /readonly switch on view.exe

    The full command also including what application to start would be the following:

    "C:\Program Files (x86)\ArchestrA\Framework\Bin\ViewAppFramework\view.exe" ViewAppPath:"C:\Program Files (x86)\ArchestrA\Framework\Bin\ViewApps\<nameofapplication>"

    1. Start by identifying the application path of your application using OMI Application Manager
    2. (You can verify syntax by using start - Run and paste your modified syntax (update with correct application path).
    3. Create a shortcut of view.exe from the folder C:\Program Files (x86)\ArchestrA\Framework\Bin\ViewAppFramework\
    4. Modify the Target to reflect the above syntax
       
    5. This should be enough to ensure ReadOnly mode to a OMI Desktop application

    Its also possible to set up in an InTouch Access Anywhere scenario using the method described here

    InTouch Has some additional methods and settings, particularly when it comes to remote desktop environment

    You can create a specific read only application that will not allow write when executed on a remote desktop server, if needed.

    When it comes to InTouch and OMI Web I'm not sure, but I believe its controlled by user groups on the server.
    aaInTouchRWUsers = Read and Write
    aaInTouchUsers = ReadOnly

    I hope it gives you some clarity in what can be done.
