Two instances in the same machine.

Hello
I have one stable version of my server-side application and one developer version, therefore 2 dll's. I'd like to be able to instantiate both on the same machine, using different ports to distinguish.
Is that possible?
I'm using Photon 2.x.
Thank you.

    yes you can create 2 instances in the configuration and start them both / restart them as needed.

    Thank you Dreamora

    Ok, so to test, I created a copy of my Server.Match.dll called Server.Match.STABLE.dll in the same directory and changed this line in the PhotonServer.config:
    Assembly="Server.Match"
    to 
    Assembly="Server.Match.STABLE"

    But I cannot start the application. I didn't create another instance, I was just trying to change the dll name. The output was this:

    I was looking for a silly name mistake but everything seems right. Do you know where I could find a more detailed log about what happened?

    did you ensure to add a new instance and properly configuring the stable / instable as distinct applications? (you can't have 1 application with 2 distinct versions)

    No, I didn't even try to create a second instance, I was just trying to make my current instance use a different dll.
    I'm not the person that did the server setup in the first time, so I do know if I'm doing the right thing. I only changed that specific line in PhotoServer.config. Is there anything else to make it use another dll?

    After this works, I will try to create the second instance.

    Did you shut down the instance and photon control before changing the config (or after it, you need to restart them anyway to make config changes taking effect)


    I assumed you want two distinct instances / applications because you asked about 'running two' not 'one or the other' :)
    Though in both cases using two instances to fire them up / down at will helps a lot as you can update them independently etc

    You are right, I want two, but before trying both I was just trying to run one with the other dll.
    I found what was wrong: I was simply renaming the file via windows, I didn't know I had to change the Assembly Name in the project settings and generate a new dll.
    Another problem:

    I'm now trying both instances. I can connect to the first, but not the second. I don't think it's a dll problem because both dll's have the same code.

    netstat showed that PhotonSocketServer.exe is using the first instance port, but no one is using the port of the second instance.

    The bad thing is that the PhotonControl icon shows that the service is running and PhotonCLR.log doesn't give a hint of what's going on:

    I also noticed that it is producing that daily log for instance 1 (Photon-Instance1-20120223.log) but not for instance 2.

    Finally got it working. I didn't know PhotoControl was only able to control one instance. This post helped me:
