Question

Creating a JRun/CF cluster and using hardware load balancing

Asked by: rot299

I am creating a hosting environment that will consist of a Hardware load balancer (CISCO CSS), 2 Windows 2003 Server Machines running IIS6 and JRun/Coldfusion. Will will also have a remote storage machine (NAS) to hold all the client data and store the websites.

What I need to know is - if I want to use session replication across the two server machines, am I able to create a JRun cluster across the two so if one fails the other will maintain the session state? Or does this conflict with how the CSS with balance the load. i.e. will the CSS direct me to one machine only to have the JRun/CFusion decide which server in the cluster to use?

Im a little confused as to how JRun should be setup when using a hardware load balancer.

Nice setup!

Read the followning articles; they should answer your questions!
http://www.macromedia.com/devnet/mx/coldfusion/articles/css_multi.html
http://www.macromedia.com/devnet/mx/coldfusion/j2ee/articles/balancing_j2ee.html
http://www.macromedia.com/devnet/mx/coldfusion/articles/dfp.html

If you have questions after reading these, fire away!

Also, if you read something about ColdFusion or JRun not working well with CSS, disregard it.  Older versions of CF and JRUN did not play well with older versions of CSS; that's all fixed now, thanks in part to Macromedia's partnership with Cisco.
 
Regards,

Seth

Thanks, however I have read those articles previously and I'm still not sure of a couple of things.

If I use the hardware load balancer in front of two machines running multiple instances of JRun/CF, should I cluster all the instances across both machines or should I have sepecrate cluster on each of the boxes?

Assuming it is best to create a cluster with all instances from both machines - do I need to register remote servers and create the cluster through the JMC on both machines or just on one so that IIS6 (one install per machine) can be connected to the cluster from both machines?

Thanks again

Use client variables stored in a database rather than session variables, this will maintain your sessions across all servers.
