A resource manager with the same identifier is already registered with the specified transaction coordinator

问题

I am consistently getting ResourceManager error. I use below code:

public static IDocumentStore Initialize()
{
    const string id = "2a5434cf-56f6-4b33-9661-5b6cc53bd9a5";
    _instance = new DocumentStore
    {
        Url = "http://localhost:8085",
        DefaultDatabase = "Testing",
        ResourceManagerId = new Guid(id)
    };
    _instance.Initialize();
    return _instance;
}

Here's the call stack:

Has anyone else come across this issue?

回答1:

Here is the solution I found:

I had created 6 endpoints for each of the endpoint I was using same ResourceManagerId. Once I created different ResourceManagerId (constant guid) for each endpoint this issue got resolved.
