Oracle Solution for Error ora-16170

ORA-16170: Terminal recovery may have left the database in an inconsistent state

What triggered the Error:

When terminal recovery is invoked in a standby database without synchronous log shipping, in the rare case of the recovery session being in an unrecoverable state, terminal recovery cannot bring the standby database to a consistent SCN boundary if the primary database continues to have redo thread(s) open.

What should we do to fix it:

Continue standby recovery with additional log shipping from primary.
