Question

JRun cluster not working

Hello, I have created 2 CF instances (cf7instance1 and cf7instance2) inside a new cluster (cluster2).  I also use a Microsoft NLB between this new virtual server this and another existing server with a cluster containing its own instances.  My problem is that when I use Fusion Reactor to view the requests going through each instance the load does not reach cf7instance2.  After looking on the server I can see that jrunserver.store does not contain the second instance at all and manually entering this does not fix my problem because once the server is restarted this setting is removed again.  Inside the JRun Administrators Guide it does state that:

When the web server connector starts for the first time, it uses the bootstrap property to detect whether the JRun server is in a cluster and saves  the IP address:JCP port of each JRun server in the cluster. For example,  if the bootstrap property points to 1.64.22.137:51000 and  that JRun server is in a cluster, the connector creates a  jrunserver.store file with a proxyservers property containing IP address:JCP port settings

Does anyone know why it can not detect that the server is in a cluster or how I can fix this problem?

    This may be simpler: did you run the Web Server Configuration tool (for CF, available in Start>Programs>Adobe>ColdFusion) and then set whatever web site you're using (in IIS) to be associated with the cluster? It may be associated with only the one instance you see. Just worth double-checking. The tool lets you see what is set, as well as to change it.

    For more info, see the CF documentation manual, "Administering and Configuring ColdFusion", available online (google can help you find it for your version).

    Yes I used the Web Server Configuration tool and set all sites to be associated with the cluster.  We are on CF7 and I have had a look through the documentation but can not identify what the problem is.

    Is the 2nd instance started?

    What happens if you stop the first instance?

    How did you create the cluster?

    How much load are you throwing at the server?
