Backup and recovery of OCR

Method 1: (equivalent to physical backup)

Oracle backs up ocr every hour. The default path for automatic backup is: $GRID_HOME/cdata/.

View backups:

[root @ rac1 ~] # / oracle/grid/crs_1/bin/ocrconfig-showbackup

View the location of backup files (automatic backup, manual backup) (on that node, under that path)

Manually trigger OCR automatic backup:

[root @ rac1 ~] # / oracle/grid/crs_1/bin/ocrconfig-manualbackup

Rac2 2020-07-23 09:54:19 / oracle/grid/crs_1/cdata/rac-cluster/backup_20200723_095419.ocr

Rac1 2020-07-23 09:26:31 / oracle/grid/crs_1/cdata/rac-cluster/backup_20200723_092631.ocr

Restore:

[root @ rac1 ~] # / oracle/grid/crs_1/bin/ocrconfig-restore file_name

Dump to view OCR information:

[root @ rac1 ~] #

/ oracle/grid/crs_1/bin/ocrdump-backupfile / oracle/grid/crs_1/cdata/rac-cluster/backup_20200723_092631.ocr

(an OCRDUMPFILE is generated under the current path)

[root @ rac1 ~] # more OCRDUMPFILE

Method 2: (equivalent to logical backup)

Export:

[root @ rac1 ~] # / oracle/grid/crs_1/bin/ocrconfig-export / tmp/ocr.bak

Import:

[root @ rac1 ~] # / oracle/grid/crs_1/bin/ocrconfig-import / tmp/ocr.bak
