I will share the solution of the error ORA-19599: block number 2678637 is corrupt in archived log /archive/1_547823_457765345.arc
Error :
ORA-19599: block number 2678637 is corrupt in archived log /archive/1_547823_457765345.arc
Solution :
We connect to RMAN and check whether the archivelogs are corrupt.
| 
					 1 2  | 
						$ rman target / RMAN> validate archivelog all;  | 
					
The archivelog which is corrupt is copied to another directory.
| 
					 1  | 
						$ cp /archive/1_547823_457765345.arc /tmp  | 
					
Since the corrupted archivelog is no longer in the archive directory, it is marked as expired by crosschecking.
| 
					 1 2  | 
						$ rman target / RMAN> crosscheck archivelog all;  | 
					
Backup is restarted.
