This chapter describes how to extend an existing Oracle Real Application Clusters (Oracle RAC) home to other nodes and instances in the cluster, and delete Oracle RAC from nodes and instances in the cluster. This chapter provides instructions for Linux and UNIX systems.
If your goal is to clone an existing Oracle RAC home to create multiple new Oracle RAC installations across the cluster, then use the cloning procedures that are described in Cloning Oracle RAC to Nodes in a New Cluster.
The topics in this chapter include the following:
Ensure that you have a current backup of Oracle Cluster Registry (OCR) before adding or deleting Oracle RAC by running the
ocrconfig -showbackup command.
The phrase "target node" as used in this chapter refers to the node to which you plan to extend the Oracle RAC environment.
