ORA-00752

recovery detected a lost write of a data block

Cause

A data block write to storage was lost during normal database operation on the primary database.


Action

Shutdown the primary database and activate the physical standby database to failover. Call Oracle Support Services. See the Data Guard documentation for details. Unless directed by Oracle Support Services, do not attempt to bypass this error by copying blocks or data files from the primary database to the standby database because that would propagate the lost write from the primary to the standby database.
