What action must you perform to achieve this?

Your database supports multiple applications. The applications run on the middle tier and
use connection pooling for connecting to the database. You notice that the sessions created
by the applications are competing for resources. You want to statistically measure the
workload and set priorities. What action must you perform to achieve this?(Choose the best
answer.)

A.
Create services for the applications and set a relative priority by assigning them to
application users and using
theDBMS_MONITOR.SERV_MOD_ACT_TRACE_ENABLEprocedure to trace the
services.

B.
Create services for the applications and set a relative priority by assigning them to
application users and using theDBMS_MONITOR.SESSION_TRACE_ENABLEprocedure
to trace the services.

C.
Create services for the applications and settherelativepriority of services within an
instance by mapping the services directly to consumer groups.

D.
Create services for the applications and set a relative priority by assigning
themtoapplication users.
