Re: Cluster creation help!

Hi Richard

Two important points for ColdFusion 10 Session Replication

1> ColdFusion 10 servers must be Enterprise Edition

2> All the Servers(Machines) should be under same Network (same subnet)

Below is the example of two IP Addresses in the same Subnet

10.40.166.xx (say 34)

10.40.166.xx (say 121)

Test Application.cfc and Test.cfm (At the bottom)

Steps to perform:

Enable the J2EE session variables for both the ColdFusion servers under Memory Variables in ColdFusion Administrator

Create a local instance (say test1) and create a remote instance (say test 2) on the remote machine.

Go ahead and Register the remote instance (test2) in the ColdFusion Administrator . Create a cluster and add both the instances (test1 and test2).

Now add the cluster tag information  in the server.xml (between </host> and </engine>) of the remote instance using the help  document of ColdFusion 10 mentioned below

http://help.adobe.com/en_US/ColdFusion/10.0/Admin/WSc3ff6d0ea778594611 72e0811cbf363c31-7ffa.html

NOTE : Make sure you change the multicast port in the server.xml of the remote instance with the Multicast port number when you create cluster in ColdFusion Admin console.

Open the context.xml of the remote instance (test2) and make sure that the “Manager pathname” is comment out.

Also, make sure that in the context.xml of local machine instance (test1),  “Manager pathname” is comment out.

Stop and Start remote instance first (test2) using command prompt and then stop and start instance (test1) using command prompt.

Place the App folder in the wwwroot of both the instances. Create a cluster using the Web Server Configuration tool using the cluster and then test the Session replication behavior.

Also, place the .cfc and .cfm in  Web root folder  (wwwroot) and then try to access the Test.cfm from there. Then note down the session ID and instance name, refresh the page and observe that the Session ID is same for other instance or not. You can stop any one instance and refresh the same page then check the same instance is getting the same session ID or not.

Application.cfc

<cfcomponent>

    <cfset this.name = "SessionApp" />

    <cfset this.sessionmanagement = "true" />

    <cfset this.sessiontimeout = createTimeSpan(0,5,0,0) />

</cfcomponent>

Test.cfm

<cfset Session.svar="Test">

<cfdump var="#Session#" />

<cfscript>

hostaddress = createObject("java", "java.net.InetAddress").localhost.getHostAddress();

</cfscript>

IP Address: <cfdump var="#hostaddress#"><br />

Hope it helps
