Oracle Fusion Middleware 12c: Oracle Service Bus Essentials — Question 2

You are concerned about the operating temperature of the database servers in your Exadata Full Rack and want to be alerted if the server exceeds 30C.
What command should you use to generate alerts for such an event?

Answer options

• A. dbmcli -e "set alert ds_temp> 30" on each database server
• B. dbmcli -e "alert metriccurrent ds_temp where metricValue > 30" on each database server
• C. dbmcli -e "set threshold ds_temp comparison='>', critical=30" on each database server
• D. dbmcli -e "create threshold ds_temp comparison='>', critical=30" on each database server

Correct answer: C

Explanation

The correct command is 'dbmcli -e "set threshold ds_temp comparison='>', critical=30" on each database server' because it establishes a critical threshold for the temperature metric. Options A and B do not properly set a threshold for alerting, as they either define an alert incorrectly or check current metrics without setting a threshold. Option D creates a threshold but does not set it as a critical alert necessary for notifications.
