How remote instances work on Coldfusion Clustering?

I have just decided to set up my site using ColdFusion clustering in the staging environment. I need to find out what code adjustments are required when we move to a cluster environment. I have two machines where Coldfusion server is installed. Till now Steps I followed:

  1. On CFServer_1 I have created a instance.(cfinstance_1)
  2. On CFServer_2 I have created another instance. (cfinstance_2)
  3. On CFServer_1 I have created a Cluster using these two instances.
  4. Now on CFServer_1 I have created a IIS site(testsite.com) pointing to my codebase.
  5. Now On CFServer_1, Using the Web Configuration Tool I have associated testsite.com with the cluster.

Now my question is Do I also need to set up the code base on the second server(CFServer_2), Create a site in IIS with same name(testsite.com) and associate the site with the cfinstance_2?

Also, make sure when you add the instances in the cluster then you must check the "Session Replication" option

The Key point is

ColdFusion 10 servers must be Enterprise Edition for Session Replication To Work.

As in Developer Edition you will never see a option(Check box) for enabling session replication. Its so strange that some forums explains that "Deselecting the Sticky Session" option leads to session replication, which I tried a lot on my local dev edition but did not worked. I do not understand why Adobe does not explain these things properly on the documentation.

Thanks a lot for the info.

Thanks

Hi Deepak,

Everything is correct

Do not worry, you need not to create a site/folder in the server where you have cfinstance_2. Just place the .cfm in the webroot only and I believe IIS is configured in the machine where you have cfinstance_1.

Yes IIS is configured on cfinstance_1. So basically all my project files and folders must be on both the machines.Am I correct?

Place the cfm in 2 different folders

1. in the webroot (say C:\inetpub\wwwroot)

2. in the cfinstance_2 webroot which is the other server (server 2) where you have this instance. The path will be C:\ColdFusion11\cfinstance_2\wwwroot

Thanks
