Hi David,
Thanks for your reply. As per hemanth's comment, I did not open the
database. After recovery is complete, I give ALTER DATABASE RECOVER MANAGED
STANDBY DATABASE DISCONNECT FROM SESSION; and immediately I see standby redo
logs complain about missing redo logs. I do not yet have a working physical
standby. Can you please send me the link of Herman's document.
