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 Windows systems.
Note:
In this chapter, the entries for Grid_home refer to the full path name for the Oracle Grid Infrastructure home, and the entries for Oracle_home refer to substitutes for environment variables for the Oracle home with Oracle RAC.
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.
This chapter includes the following topics:
Note:
Ensure that you have a current backup of Oracle Cluster Registry (OCR) before adding or deleting Oracle RAC by running the ocrconfig -showbackup command.
For all of the add node and delete node procedures, temporary directories such as %TEMP% or C:\Temp should not be shared directories. If your temporary directories are shared, then set your temporary environment variable, such as %TEMP%, to a ___location on a local node. In addition, use a directory path that exists on all of the nodes.
