High Availability Data Guard, Sharding and Global Data Services (MOSC)

MOSC Banner

Down time:


I have 11.2.0.3 RAC 4nodes in production (Prim) to local standby and from local standby to DR site data guard setup. we need to apply kernel patches to all our servers  and siince we will be rebooting one node at a time do we need still need to defer the log shipment between primary , local standby and DR site? if so should I start it from primary first or DR?

 

I guess I am trying to find the best case scenario any feedback will be appreciated.
