Oracle Error Message
ORA-19943: The current database incarnation changed during backup
Reason for the Error
The backup failed because the current database incarnation was changed during the backup. One of the following events caused this incarnation change:
– The database was opened using ALTER DATABASE OPEN RESETLOGS statement.
– RMAN command RESET DATABASE TO INCARNATION was issued.
– If this happened on physical standby database, then redo apply has applied redo data from a new database incarnation.
Solution
Re-try the backup.
