Removing an Oracle Cluster Registry Location

To remove an OCR location or a failed OCR location, at least one other OCR must be online. You can remove an OCR location to reduce OCR-related overhead or to stop mirroring your OCR because you moved OCR to redundant storage such as RAID.

Perform the following procedure as the root user to remove an OCR location from your Oracle Clusterware environment:

Ensure that at least one OCR location other than the OCR location that you are removing is online.

Caution:

Do not perform this OCR removal procedure unless there is at least one other active OCR location online.
Run the following command on any node in the cluster to remove an OCR location from either Oracle ASM or other location:
```
# ocrconfig -delete +ASM_disk_group | file_name
```
The file_name variable can be a device name or a file name. This command updates the OCR configuration on all of the nodes on which Oracle Clusterware is running.

Note:

The only configured Oracle ASM OCR location, which is on a different Oracle ASM disk group than the Oracle ASM OCR backup location, cannot be removed.
