Have an issue running 2 instances of a Trinity console app?

[mwherman2000]

I'm overriding the ports properly, ...that's not the problem...

            TrinityConfig.HttpPort = nodePort;
#pragma warning disable CS0612 // Type or member is obsolete
            TrinityConfig.ServerPort = TrinityConfig.HttpPort + 1;
#pragma warning restore CS0612 // Type or member is obsolete

The problem seems to be because I'm running each instance out of the same "Debug" folder in Visual Studio. See below.

How can I override/specify which Trinity database folder to use? Is this what I need to be able to do?

NOTE: If I make a copy of my "Debug" folder and run an instance out of each folder, things appear to work fine.

@mwherman2000 Each instance of the graph engine server must run on a separate IP port; you can't have each instance write to the same persistence store. There are at least two ways to configure the graph engine:

• at runtime you can point to a an xml config file like this: TrinityConfig.LoadConfig(@"D:\Trinity TripleStore Server Deployment\trinity.xml");

  
          //TrinityConfig.LoggingLevel = LogLevel.Info;
          //TrinityConfig.Servers.Add(graphEngineCluster);
          //TrinityConfig.CurrentRunningMode = RunningMode.Server;
          //TrinityConfig.AddServer(TripleStoreServerInfo);
          //TrinityConfig.LogEchoOnConsole = true;
          //TrinityConfig.StorageRoot = TripleStoreStorageRoot;

  or you can configure you xml config file

  ```

Each GE App Server instance must run against its own configuration data. If you are running two servers then you may want to run them in a GE Availability Cluster. Here is an example of how I am doing so in one of dev environments:

<?xml version="1.0" encoding="utf-8" ?>

    <!-- <Local Template="primary-rub-truespark-sf-cluster-template"/>-->
    <!-- <Remote Template="rub-truespark-ontology-taxonomy-cluster-template"/>-->

    <!--A Cluster node contains configurations for servers and proxies of a Graph Engine cluster. 
        There can be multiple Cluster nodes as long as they have different identifiers. 
                        Endpoint="10.1.10.5:7001" 
        A Cluster node can have an optional attribute Id.-->

It looks like the key (minimal) thing I need to do is have each instance specify it's own StorageRoot:

            <Storage TrunkCount="256"
                ReadOnly="FALSE" 
                StorageCapacity="Max16G" 
                StorageRoot="D:\GraphEngine-Storage" 
                DefragInterval="600"/>

I'm already overriding the ports. :-) Thank you.
