I had one production database around 1 Tb and it is Non-RAC instance. I am creating new 2-node RAC environment on Aix 5.3 using GPFS for Database storage. Both Existing and new GPFS storage is on same SAN. I had never worked with GPFS which I think might not be different from regular file system except that it is shared.

 

Now in order to reduce the production downtime, I had to move existing Non-RAC database to RAC instance and I really appreciate if somebody can verify if the following approach is feasible and allowed or any other option/approach

 

I am thinking to create Physcial Standby on new RAC instance and

During Final Production deployment, I will  activate the Standby after applying all required changes from production and then use reconfig to change the single instance to RAC with storage as GPFS

 

Thanks
