In the event that the HADR standby database encounters an error on a particular table space during log replay, the standby database will continue to replay logs on other table spaces but will stop replaying logs on the affected table space.
The affected table space's tablespace state will be changed to restore pending, rollforward pending, or offline. You need to recover the table space on the standby because data in this table space will not be available if this database takes over the primary role.
