Which two situations require that your Database as a Service (DBaaS) instance be scaled
up?

A.
The DBaaS instance is maxed out on semaphore sets.

B.
The database instance has reached the limit in thelicense_max_sessionsdatabase
parameter.

C.
The DBaaS instance is maxed out on CPU.

D.
The database instance is out of space in the sysaux and system tablespaces.

E.
The DBaaS instance is maxed out on storage.

F.
The DBaaS instance is maxed out on semaphores.

Explanation:
Existing DBCS instances may scale up to bigger shapes in OCPU, Memory and Storage
for vertical scaling. For horizontal scaling, DBCS provides RAC with the Extreme
Performance option currently allowing applications to scale up to 2 nodes, each with a max
of 16OCPU shapes.
Note: An Oracle CPU (OCPU) provides CPU capacity equivalent of one physical core of an
Intel Xeon processor with hyper threading enabled. Each OCPU corresponds to two
hardware execution threads, known as vCPUs.
