Configuring a cluster at the secondary site
To set up a multi-node or single-node cluster on the secondary site:
Set up the cluster
Set up the database
The setup requirements for the secondary site parallel the requirements for the primary site with a few additions or exceptions as noted below.
Important requirements for global clustering:
Cluster names on the primary and secondary sites must be unique.
Make sure that you use the same OS user and group IDs for Oracle for installation and configuration on both the primary and secondary clusters.
