How to set up dynamic cluster

Follow the Creating a new dynamic cluster on Windows using WebSphere Virtual Enterprise document to setup a dynamic cluster.


The basic steps for creating dynamic cluster can be divided into three basic parts

Preparing DM and portal nodes

• Install and configure Deployment Manager


• Install WAS XD and augment the deployment manager profile


• On all the WebSphere portal servers install WAS XD and augment wp_profile

Adding Primary Node to dynamic cluster

• Prepare the node for dynamic cluster
  
  
  
  • cluster-node-config-pre-federation
  
  
  • Optional tasks if your using look aside repository or database backed user registry
  
  
  • cluster-node-config-post-federation
  
  
  • wp-change-portal-admin-user
  
  
  
  


• Login into WAS Admin consol and Create a node group


• Add primary portal server as node to the node group


• Create Dynamic cluster, in the WAS Admin Console


• Create the primary portal node as cluster member using the existing server as a template


• Create dynamic cluster by executing cluster-node-config-dynamic-cluster-setup config task


• Access the web content management content:Set the WCM_HOST and WCM_POST websphere variables at the primary portal server level to point to the web server host name and port name through which the WCM content would be accessed.


• Propogate the changes
  
  
  
  • Stop DM
  
  
  • Stop Node Agent
  
  
  • Stop Server 1
  
  
  • Stop portal server
  
  
  • start DM
  
  
  • Start Node
  
  
  • Start Server1
  
  
  • Start WebSPhere POrtal
  
  
  • 
    
  
  

Adding additional nodes to the cluster

• Setup the wkplc_dbtype.properties and wkplc_comp.properties files to point to correct database


• Validate database settings by executing
  
  
  
  • validate-database-driver
  
  
  • validate-database-connections
  
  
  
  


• Prepare the node for dynamic cluster
  
  
  
  • cluster-node-config-pre-federation
  
  
  • Optional tasks if your using look aside repository or database backed user registry
  
  
  • cluster-node-config-post-federation
  
  
  • wp-change-portal-admin-user
  
  
  
  


• Login into the WAS Admin Console and add the new node as new member to the node group


• Run the ConfigEngine.bat/sh cluster-node-config-dynamic-cluster-setup task to add the new member to the existing dynamic cluster


• Apply changes by restarting the server


• Access the Web Content Management Content by changing value of WCM_HOST and WCM_PORT websphere variables at the nodename scope to indicate the name of the fully qualified host and port
