Oracle Database - Enterprise Edition - Version 10.2.0.1 and later Enterprise Manager for Oracle Database - Version 22.214.171.124 to 126.96.36.199 [Release 11.2] Oracle Database Cloud Schema Service - Version N/A and later Oracle Database Exadata Cloud Machine - Version N/A and later Oracle Cloud Infrastructure - Database Service - Version N/A and later Information in this document applies to any platform.
Creating a RAC duplicate (clone) database from an existing RAC Database.
Install/Prepare Oracle Clusterware (aka Grid infrastructure in 11g onwards) in clone Nodes
Install Oracle RDBMS software Home in clone Nodes
Make sure that all required pre-requisites / setup for Clusterware / Grid Infrastructure / RAC Oracle Home are executed and verified.
In case of ASM storage, create required ASM diskgroups accessible to all clone Nodes.
Use RMAN DUPLICATE to create a non-RAC database (cluster_database=FALSE) in any one of the clone nodes. In our example we will use RMAN ACTIVE DUPLICATE method introduced in 11g.
