taken using clusterware utilities.

B.
Option B
C.
Option C
D.
Option D
E.
Option E
Explanation:
Run the following command to list the backup files: ocrconfig -showbackup The ocrconfig –
showbackup command displays the backup location, timestamp, and the originating node name of
the backup files that Oracle Clusterware creates. By default, the showbackup option displays
information for both automatic and manual backups but you caninclude the auto or manual flag to
display only the automatic backup information or only the manual backup information, respectively.
Run the following command to inspect the contents and verify the integrity of the backup file:
ocrdump -backupfilebackup_file_name You can use any backup software to copy the automatically
generated backup files at least once daily to a different device from where the primary OCR resides.
Right answer is “A”:
To restore OLR:
# crsctl stop crs
# ocrconfig -local -restore file_name
# ocrcheck -local
# crsctl start crs
$ cluvfy comp olr
