You also can use the ocrconfig command to add/delete/replace OCR files, and you can add another
mirror of OCR in +DATA2:
$GRID_HOME/bin/ocrconfig -add +DATA2
Or remove the OCR copy from +DATA1 :
$GRID_HOME/bin/ocrconfig -delete +DATA1
The
ocrdump
command can be used to dump the contents of the OCR to a .txt or .xml file. It can be executed only
by the root user, and the default file name is OCRDUMPFILE:
$ ./ocrdump
$ ls -l OCRDUMPFILE
-rw------- 1 root root 212551 Dec 28 20:21 OCRDUMPFILE
The OCR is backed up automatically every four hours on at least one of the nodes in the cluster. The backups are
stored in the
$GRID_HOME/cdata/<cluster_name>
directory. To show the backup information, use the
ocrconfig -showbackup
command:
$GRID_HOME/bin/ocrconfig -showbackup

The steps to restore OCR from a backup file are as follows:
1.
Identify the backup by using the
ocrconfig -showbackup
command.
2.
Stop the clusterware on all the cluster nodes.
3.
Perform the restore with the restore command:
ocrconfig -restore file_name
4.
Restart the crs and do an OCR integrity check by using
cluvfy comp ocr.
