The DBA has determined that number of OCPU assigned to an Autonomous Database does not provide sufficient performance. Which option does the DBA have in this case?
A.
Open the database in OCI Console and increase the number of OCPU. No downtime required.
B.
No downtime is required as number of OCPU can be increased from OCI console, but users have to be informed that they must not use any application for at least one hour.
C.
Call Oracle Cloud Support and raise a request to increase number of OCPU. Expect a downtime of approximately one hour.
D.
Plan for a one-hour downtime and increase the number of OCPU while database is of-fline.
This option is the correct way to increase the number of OCPU assigned to an Autonomous Database. According to the Oracle documentation2, “You can scale your Autonomous Database on demand by adding CPU cores or storage. You can also enable auto scaling to allow your Autonomous Database to automatically use up to three times more CPU and IO resources than its allocated CPU core count.” The scaling operation does not require any downtime or affect the availability of the database.
