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 use use to generate alerts…

Question

Options

• Adbmcli -e "set alert ds_temp> 30" on each database server
• Bdbmcli -e "set threshold ds_temp comparison=' >', critical=30" on each database server
• Cdbmcli -e "alert metriccurrent ds_temp where metricValue > 30" on each database server
• Ddbmcli -e "create threshold ds_temp comparison='>', critical=30" on each database server

• A
  11% (3)
• B
  7% (2)
• C
  4% (1)
• D
  79% (22)

Explanation

According to Oracle's documentation, to set a threshold for a metric on a database server, you need to use the create threshold command with the appropriate parameters. The set threshold command is used to modify an existing threshold. Therefore, the command that you should use to generate alerts for such an event is: dbmcli -e "create threshold ds_temp comparison=`>', critical=30" on each database server
