This note outlines the procedure to clone or refresh an Oracle Real Application Clusters database using the RMAN Duplicate Database feature.
In case of a RAC to RAC clone, with RMAN Duplicate we first create a target or duplicate single instance database and then convert the single instance database to a RAC database.
While the note deals with an Oracle 10.2.0.4 database, the same procedure can be used for an 11g database. However, note that in 11g we now have the Duplicate From Active enhanced feature as well.
