Your production database is running in the ARCHIVELOG mode and you are using Recovery Manager (RMAN)
with a recovery catalog to perform the database backup at regular intervals. When you attempt to restart the
database instance after a regular maintenance task on Sunday, the database fails to open, displaying the
message that the data file belonging to the SYSTEM tablespace is corrupt.
The steps to recover the damaged data files are as follows:
1. Mount the database
2. Open the database
3. Apply the archived redo logs.
4. Restore the data file
5. Make the tablespace offline.
6. Make the tablespace online.
