Database sharing between multiple clusters

You might want to support multiple identically configured HCL Portal installations in the same cell for ease of maintenance or failover.

If two independently configured clusters exist within the same cell, each cluster must have its own set of database domains. If two clusters that are identically configured exist within the same cell, all database instances must be shared except the release and JCR database domain. All user-specific and community data is shared between clusters, while each cluster's static configuration can be independently updated.


Database settings

When we configure multiple clusters in the same IBM WebSphere Application Server cell, special attention must be given to the database settings.
