Install two instances of Aras V11 in the same machine

Hello All,

I have installed an instance of Aras Innovator V11 SP15 with the following url : http://MachineName/InnovatorServerOne/Client, using create a new database (dbOne) during installation.
what i want to do is adding or installing another instance (InnovatorServerTwo) of Aras V11 SP15 in the same machine using a database (dbTwo) that already exist.

Is there any idea please on how to add this second instance with the following url :http://MachineName/InnovatorServerTwo/Client  ?

  • Hi Mouad,

    If your goal is having two seperate 11sp15 databases, I would recommend just adding an additional <DB-Connection> tag within your innovatorserverconfig.xml file, which can be located in the root of your aras installation. This will allow you to log into both databases from a your "innovatorServerOne" url.

    If you'd like to have two separate instances, you'll have to modify the GUID of the installer process to load an additional instance to your machine. Subscribers have access to the CD image which contains a changeGUID.exe file within the utilities folder. Dragging the installer on top of this executable will change the GUID of its installer, allowing for a parallel download. Just ensure that when you're running through the installer that you're giving everything unique names.


  • Hello AJ Sebastian,

    Thanks for your reply,

    the goal is to have two separate instances, means two different url (InnovatorServerOne, InnovatorServerTwo) and two different Vault directories.

    The first solution that you have proposed allow just to log into both databases using the same url (InnovatorServerOne).

    By the way i have executed the file specifying the full path to the installer using Administrator command prompt : ChangeGUID <path>\InnovatorSetup.msi  but nothing  happens.

    ChangeGUID.exe is it comaptible with windows server 2016 ?

  • The executable should be compatible with windows server 2016. The way I normally achieve this is by dragging the innovatorSetup.msi file on top of the executable(which can be found in the utilities folder). The result looks something like this:

    Once you drag and drop, the executable quickly runs in the background, and upon opening the msi file you'll be prompted for a fresh install. 

  • Thank you so much AJ Sebastian for your help, its works fine with this option 100

  • Hello AJ Sebastian,

    I have done the needfull, the second instance installed successfully but i am unable to see changes when i execute a client Event method.

    Server event method works fine as when i execute the method i can see the changes.

    I have tested with a simple client method that contains just an alert but no changes are applied in the application. 

    Is there any missing configuration shoud be done ? as this is so strange

  • Hi Moaud,

    Assuming you're making/testing the changes in the same instance, I would recommend clearing your browser cache. It shouldn't make much of a difference unless you're modifying code tree files, however it's always one of my first steps when troubleshooting a client-side error or any strange behavior. 

    But to answer your question, there shouldn't be any additional requirements to have to parallel innovator instances running on one machine. Have you tried creating the client event in both instances? Does it work in one, both, or neither?


  • Hi AJ Sebastian,

    I have tried creating the client event (alert) in the first instance already installed and it's works fine, but it's not working in the second instance as i didn't see any changes even if i clear the browser cache.

    Is there any other idea please ? as i'm still stuck on this.

  • Note that i have tried to add " debugger; " to the client method as you see in the screenshot below and nothing happens.

    but when i add the client method to the form (Part) of the itemType Part it's works fine with or without debugger option.

  • How are you executing the client method? What kind of client event are you attaching it to? Is it configured identically in the first instance?

  • Hi AJ Sebastian,
    the client method executed by clicking in the category concerned then the button   with the event onFormPopulated.

    Note that the IemType concerned is no longer displayed in the category in the TOC Pane and the list of categories does not show the category of the ItemType in question.
