Hi Can anyone share the doc/reference for doing DR exercise for 4-node Primary RAC (11g R2) on 2-node DR RAC ? We have 4-Node Oracle 11g R2 RAC with 8 Databases using ASM based OCR/Voting and Databases on Linux environment. Now Company wants to perform a DR exercise where backup from Primary Tape will be used to create the DR environment using only 2nodes. So I appreciate if someone share experience in RAC cloning/Setup as what are the steps for Grid Infrasturcture cloning. TIA Sanjay
