Nassyam Create Dataguard from 4node to 2 node is not an issue. The main requirement is how to clone Oracle Grid infrastructure using the backup taken for software on Primary site. It is DR exercise where Database restore is not a challenge as long as Grid infrastructure is ready. So key challenges are to identify the various script to be executed after the Software from one of the node is restored on the DR exercise server and how to create the various configuration files including ASM based ocr/voting disk and other ASM configuration. Once this is done, Database cloning using Tape restore will not be an issue. This is one time exercise to check and document the procedure to rebuild the environment from offshore tape backup TIA Sanjay On Thursday, December 12, 2013 1:52 PM, Nassyam Basha <nassyambasha_at_gmail.com> wrote: Hi Sanjay, Are you looking for 4-node to 2-node DR setup? If so you can refer below links. I usually refer MAA documents. http://www.oracle.com/au/products/database/maa-wp-10g-racprimaryracphysicalsta-131940.pdf http://www.oracledba.org/11gR2/dr/11gR2_dataguard_RAC_to_RAC.html documentsay point to 2-node standby or 3-node, you may need to perform changes only few parameters like FAL_SERVER, LOG_ARCHIVE_CONFIG so on. You will get idea if you refer those links. Documents you may not get exactly as per your environment, you can refer them and of course you can modify steps as required. Hope this helps. But the below question is confusing still, can you describe more ? what are the steps for Grid Infrasturcture cloning?

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
