RE: Access individual instances in a cluster without JWS?
Hello, I tried to set up as you suggested, but the admin instances still gets clustered as soon as I recreate the cluster. I set up the individual admin instances to separate virtual servers - and the apps is on other instances. After the setup there is 2 admin virtual servers not clustered in wsconfig, and the app instances clustered. I's give up for now, clustering with session replication is working if I don't use the internal JWS.

First, you'll need to create multiple virtual servers in IIS - one for the cluster, and one for each instance. Next, you'll need to use wsconfig to delete the current connection between your cluster and IIS, then delete the cluster itself (not the cluster members, just the cluster). Then, use wsconfig to connect each instance to the appropriate IIS virtual server only - don't connect it to all IIS virtual servers. Finally, recreate your cluster, and reconnect it to the appropriate IIS virtual server, and you should be all set.

RE: Access individual instances in a cluster without JWS?
Hello, Not sure if it's a bug or if it's by design - maybe session replication and JWS doesn't work together and cannot work together. I've tried this on 2 separate setups Both with 2 physical servers and 2 jrun instances on each, 2 network cards. No probles with the clustering itself, it all happens with JWS and session replication enabled at the same time. As soon as I enable session replication in the cluster the logs goes bananas with setup of session replication failed. I've filed a bug report. I'll keep looking, and if anyone have experienced this and found a way out I would be grateful for suggestions.

Is this a bug in JWS or will it stay this way forever? I cannot hope for a fix from Adobe on this? Well, I wasn't aware of a bug in JWS that would cause this, as I've set up clusters that used JWS to address the individual members and IIS or Apache to address the cluster. But I don't use session replication that much, honestly. Can you provide more information about the bug? Alternatively, you could configure a management interface in Apache for each instance. You'll have to do that by hand, though - the wsconfig tool only gets you so far with Apache.

RE: Access individual instances in a cluster without JWS?
Hi, That would work if our app was less complex, too much work involved.. We've developed on it the last 8 years and have used the session scope since it was possible. We use sticky sessions and also cookie based persistence in the load balancer (Coyote) and it's pretty stable, users is seldom balanced over to the other servers - but session replication would make it even more stable.

The other clustering approach is to use Client scope rather than Session scope. To overly simplify things, Client scope is a contract between the user's browser and the application, whereas Session scope is a contract between the user's browser and the server. Since Client scope can maintain state with the application, a user can be seamlessly bounced from server to server without loss of data / connection. Works really well behind hardware load balancing, for example. Not so sure it fits your situation, but thought I'd at least mention it in case.

Re: Access individual instances in a cluster without JWS?
Ah, that might explain why session replication doesn't work for us either. We decided that session replication was unnecessary; we certainly need the JWS far more than session replication, if that's actually the cause.

Re: Access individual instances in a cluster without JWS?
We leave the built-in JRun webserver turned on. You can then just call
http://{servername}:{jrunserver port}/cfide/administrator to access each
instance. You can even use SSL (as long as you don't have JVM 1.6
installed!). This assumes that you're using JRun... I'm not sure how
other J2EE platforms are set up. This has worked for us from MX 6.1 - 8.01.
