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.
