Which two methods exist for enabling the collection of additional resource debugging information for specific
resources controlled by Oracle 12c Clusterware?

A.
Use the cluvfy comp command for the specific resource within a component.

B.
Use the crsctl set trace res “resource_name=debugging_level” command.

C.
Use the crsctl set log res “resource_name=debugging_level” command.

D.
Set the environment variable _USA_ORA_DEBUG=1 and then stop and restart the resource that requires
resource debugging data to be collected.

Explanation:
B: You can enable tracing for Oracle Clusterware resources by running the crsctl set trace command, using the
following syntax:
crsctl set trace module_name “component_name=tracing_level,…”
C: The crsctl syntax to enable debugging for resources is:
crsctl debug log res “resname:1”
Incorrect Answers:
A: Cluster Verification Utility (CVU) performs system checks in preparation for installation, patch updates, or
other system changes. Using CVU ensures that you have completed the required system configuration and
preinstallation steps so that your Oracle Grid Infrastructure or Oracle Real Application Clusters (Oracle RAC)
installation, update, or patch operation, completes successfully.
D: There is no USA_ORA_DEBUG environment variable.
