12c Database : ASM Enhancements : OCR backup to disk group

Oracle Cluster Registry (OCR) backup in ASM disk group

Before to 12c the ocr backup is located in the master node local disk at GRID_HOME/cdata/backup, but if OCR is corrupted and you have to restore you will need to find the master node and initiate the restore option.

Storing the OCR backup in an Oracle ASM disk group simplifies OCR management by permitting access to the OCR backup from any node in the cluster should an OCR recovery become necessary.

Use ocrconfig command to specify an OCR backup location in an Oracle ASM disk group:

# ocrconfig –backuploc +DATA

 

-Thanks
