Hi,

I am looking for any resources to confirm if this is possible, I have a primary site with 3 RAC nodes and 2 nodes in standby DR site.

  1. Is it possible to build a Oracle data guard physical standby with different number of nodes in primary (3) and standby (2) ?
  2. How should I configure the primary RAC nodes redo thread and standby redo thread ? , 3 nodes in primary and 2 nodes in standby ?
  3. Can Data guard broker be used to manage the environment ?
  4. How will this affect the Switch-over/fail-over scenarios ?

Any details/ideas are welcome.
