Which three statements are true about cluster (OCR) and local registries (OLR)?

A.
The ocrdump command can be used to dump the contents of either the cluster registry (OCR)
or the local registry (OLR).

B.
Information in the OCR is organized by keys that are associated with privileges. Therefore, the
root user will see more information when using ocrdump than the grid user.

C.
After the cluster is created, the size of the OCR is static unless the Clusterware software Is
upgraded.

D.
The ocrdump command can be used to dump information for a single OCR key.

Explanation:
You can use several options for OCRDUMP. For example, you can limit the output
to a key and its descendents. You can also write the contents to an XML file that you can view
using a browser. OCRDUMP writes the OCR keys as ASCII strings and values in a data type
format. OCRDUMP retrieves header information based on a best effort basis.
Displays OCR content in the terminal window in XML format
ocrdump -stdout -backupfile Grid_home/cdata/cluster_name/file_name
Displays the content of the in the Grid_home/cdata/ cluster_name/ file_ name directory. You must
run this command as root to be able to view all of the keys.
