Recovery copy failed with ORA-19563: datafile header validation
Did someone try incremental merge with more than one L1 backup? I tried to merge 3 L1 at once and always get datafile header invalid error. It seems the merge broken the original copy.
Here are the steps:
- run 2~3 times L1 backup of this command.
BACKUP INCREMENTAL LEVEL 1 FOR RECOVER OF COPY WITH TAG 'test' DATABASE;
2 . merge back to copy :
RECOVER COPY OF DATABASE WITH TAG 'test';
and then, there are errors like this:
RMAN-03002: failure of recover command at 10/12/2022 14:43:41
ORA-19870: error while restoring backup piece /oradb-bkp/i01a1b4a_6720_1_1_s-6720_I-2867525376
