How to Cluster WebCenter Sites 12.2.1.x.x (Doc ID 2115388.1)

Last updated on FEBRUARY 24, 2023

Applies to:

Oracle WebCenter Sites - Version and later
Information in this document applies to any platform.


In WebCenter Sites 12.2.1 there are a number of different ways to configure a cluster, for instance it can be done almost entirely from the config wizard (although a number of manual steps are still required), or from the WebLogic console. This document follows the use of the WebLogic console as it is more flexible and allows for cluster expansion after the initial setup. The order of the steps may seem out of place, for instance a cluster is configured before a single node install is completed, but by following the order provided the number of changes post installation are limited to the fewest possible steps.

This KM Note covers:

  1. Horizontal Clustering
    • Clustering Sites/CAS
    • Clustering Visitors Services (See How to Cluster WebCenter Sites Visitor Services 12c? (Doc ID 2120761.1))
    • Clustering SiteCapture (See How to Cluster WebCenter Sites - Site Capture 12c? (Doc ID 2121258.1))
  2. Moving CAS to a different cluster than Sites

Not covered:

1. Vertical clustering

NOTE: While Vertical clustering is similar to horizontal clustering described in this document it is not suggested. If there is a situation where a vertical cluster is required to fully utilize a server than virtualization of said server leads to better results.

2. Clustering Insights
