ORA-12942

database incarnation at source does not match

Cause

A request to send data blocks to a recovery process failed because the source of the blocks is not on the same database incarnation as the site where the recovery is being performed.


Action

Use standard Oracle Data Guard procedures to synchronize the primary and standby databases. Standby media recovery automatically tries to resolve many of the remaining nonlogged blocks on the standby database. To resolve any remaining nonlogged blocks, use the RMAN RECOVER ... NONLOGGED BLOCK command.
