A junior DBA is learning how to administer an Oracle Cluster and asks you how to diagnose voting disk online and offline problems, and where to find information on voting disk online and offline messages.
What would you advise this junior colleague?
A.
There is no method to get this type of information.
B.
Use evmwatch to make this kind of information visible.
C.
Enable CSS debugging by using CRSCTL to make this information available.
D.
Write a shell script that writes the output of crsctl query css votedisk to a file on a regular basis.
E.
Look in the alert_.log file in the unified message and the tracefile directory in ORA_CRS_HOME because the Oracle Clusterware logs this kind of information by default.
