Lee, As Adam more or less mentioned, CFCs instantiated into the session scope cannot be replicated across cluster nodes in CF7 (though it's possible in CF8). You may want to try leaving sticky session turned on in JRun and just count on replication for failover. It's on by default in JRun when you setup a cluster and I suspect there may be a reason for that. Even if you have a webserver cluster in front of the JRun cluster and sticky session are turned off on your webserver layer the JRun connector will continue to send requests to the same cluster node by default except in a failover situation.
Did you have this working on a 6.x cluster before or is this the first time this app has ever been clustered? -Cameron On Dec 17, 2007 3:21 PM, Clontz Jr., Lee <[EMAIL PROTECTED]> wrote: > > > > > Hey, everyone – > > > > We're implanting a CF7 cluster in a new university Web hosting environment > and we've hit a few snags.
