Will do, I'll never try to setup session replication again, I'll never try to setup session replication agai... :)
But, the below described procedure - it's 100% accurate for setting up a cluster? (not ticking of the "replicate sessions" this time.. :)) ------------------------------ JRun instances All new CF instances is created from the default CFusion instance which is shut down and "never used" after the setup is done (same goes with JRun Admin Instance) Internal webserver on every CF instance is active with separate port addresses and separate instance names (8300 for admin, 8301 for instance one "cfusion1", 8302 for instance two "cfusion2", 8303 for instance 3 "cfusion3" on physical server #2 etc.) Every CF instance have the remote port (JNDI port) set unique (both server wide and cluster wide) Clustering setup On one server (CFadmin / Instance manager) all remote instances is registered On the same server one cluster is created with round robin / sticky sessions / and replicate sessions set All instances is added to the clusters (for example 6 instances on 3 physical servers on the same subnet) (After this the servers is physically restarted) Connector setup On every physical server the Web Server Configuration Tool is run On every physical server the IIS webserver is configured with this settings: JRun Host: [The server where cluster was created initially] JRun Server: [The cluster name] All IIS websites (The server has multiple websites, hundreds) Configure web server for cf 7/8/9 apps ----------------------------- Regards, Helge -----Original Message----- From: Mark A.

I should have left that one out of it.. It seems to have hidden the real question which is: "what is the 100% correct way to create a cluster as this." Thanks, Helge -----Original Message----- From: Jason Fisher [mailto:ja...@wanax.com] Subject: Re: Clustering ColdFusion - some "black holes" I agree with Dave on this one: set sticky sessions on the LB, and let each web server stand independently so there are no single failure points. If you need true failover, refactor the apps to use client vars and store them in a database for clean 'session' replication across the web servers. ---------------------------------------- From: "Dave Watts" <dwa...@figleaf.com> Sent: Tuesday, January 25, 2011 9:11 AM To: "cf-talk" <cf-talk@houseoffusion.com> Subject: Re: Clustering ColdFusion - some "black holes" > Goal: > One rock stable high performance ColdFusion cluster with session replication and quick > failover Is there a specific requirement for session replication? Because you might get generally better results if you just use sticky sessions. That buys you load balancing, but not complete failover - but it may be enough, if your failure rate is acceptably low. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:341200 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
