Preparing additional nodes

Adding an additional node to your topology is a required step when configuring horizontal clustering.

About this task

This section applies only to clustering with horizontal cluster members.

As part of the cluster that runs the WebSphere Commerce application, you must install WebSphere Application Server, and your database client on each machine that will be part of the cluster containing the horizontal cluster members.

To prepare a new node as a horizontal cluster member:

Procedure

  1. SolarisDB2LinuxAIXInstall your database client software on the machine hosting the horizontal cluster member. The installation wizard can install the DB2 Administration Client on the machine.
  2. OracleInstall the Oracle components for an Oracle client machine. Ensure that you can access the WebSphere Commerce database from the new WebSphere Commerce node. For help in ensuring access to the remote WebSphere Commerce database, refer to your Oracle Database documentation.
  3. SolarisLinuxAIXCreate the WebSphere Application Server non-root user and group if they do not already exist on the new node.
  4. SolarisLinuxAIXEnsure that the WebSphere Commerce non-root user has the permission to access your the WebSphere Commerce Database by adding the following to the WebSphere Commerce non-root user's profile:
    if [ -f "/home/db2_user/sqllib/db2profile" ]; then 
. /home/db2_user/sqllib/db2profile
fi
  5. Install the WebSphere Application Server on the machine that is hosting the horizontal cluster member.
  6. Ensure you have the correct WebSphere Application Server level, and fixes installed, on the machine that is hosting the horizontal cluster member.
  7. Create a WebSphere custom profile.
  8. Federating additional WebSphere Commerce nodes.
