Step-by-step guide to Portal clustering

Installing and Clustering WebSphere Application Server (WAS) 7.0.0.5 and WebSphere Portal 6.1.5

Below are the major steps required to perform for Installing and clustering WebSphere Application Server and WebSphere Portal:

1. Install WebSphere Application Server Network Deployment 7.0.0.0 on the machine.
a. Select "None" during the step of creating a profile. WebSphere Portal will create its own WebSphere Application Server Profile later.
2. Update WebSphere Application Server to 7.0.0.5 level by installing respective fix pack. You can go to a higher version as well if available. Apply all available fixes as well. This is the minimum required. Apply both WAS and SDK fix packs.
3. Install Portal. Select "Full" install to install everything or "Administrative install" to install blank portal with only Administration Portlets. Apply any fix packs and fixes available to make sure that portal version is current and update with all the fixes.
4. Install Deployment Manager or create a new profile using "Profile Management Tool". Select "Management" and "Deployment Manager" in the profile sections. Install all fix packs and fixes as have been applied to WebSphere Application Server in the previous section to make sure that Deployment Manager and Application Server are on the same level if you are installing a fresh copy of Application Server for deployment manager.
5. Configure Deployment Manager, create a group called "wpsadmins", create exactly the same user as you have provided during the Portal installation and add this user to "wpsadmins" group.
6. Configure Portal for federation.
