Question #: 39
Topic #: 9

Which statement describes the usage of Dynamic Service Fallback in Oracle RAC 19c?

ADynamic Service Fallback allows a service to relocate to an available instance when the service is stopped on a preferred instance.

BDynamic Service Fallback allows a service to fall back to a preferred instance when the available instance performance falls below a specified threshold after it was failed over to an available instance.

CTo enable Dynamic Service Fallback, you should specify the level of performance of a preferred instance for a service to be relocated to an available instance by setting the -fallback attribute of a service to 'Low, Medium, or High'.

DDynamic Service Fallback allows a service to fall back to a preferred instance when it becomes available after it was failed over to an available instance.
Dynamic Service Fallback allows a service to fall back to a preferred instance when it becomes available after it was failed over to an available instance. This is true because Dynamic Service Fallback is a new feature in Oracle RAC 19c that enables a dynamic database service to automatically relocate to a preferred instance when it is restored, after the service was failed over to an available instance due to the failure of the last preferred instance. This feature improves the availability and performance of the service by minimizing the manual intervention and the number of failovers.To enable Dynamic Service Fallback, you should specify the -failback option for the service as YES when using SRVCTL or DBCA12.Reference:
: Oracle Database 19c Release 19.3 New Features, Dynamic Services Fallback Option1
: Automatic Failback of a Service in a Oracle-19c-RAC-Database2

Dynamic Service Fallback? More like 'Dynamic Service Boomerang', amirite? *chuckles* Okay, I'll see myself out.

I'm not sure, I think it might be A. It makes sense for a service to relocate to an available instance when the preferred one is stopped.

I wonder if the -fallback attribute is like a knob we can tweak to control how aggressively the service tries to failback. Gotta love those granular tuning options!

I agree with you, Anna. Dynamic Service Fallback is really important for improving service availability.

Wait, so we don't have to manually relocate the service back to the preferred instance? That's a game-changer! This will save us a lot of time and headaches.

Dynamic Service Fallback sounds like a cool feature that can really improve the availability and performance of our services. I'm glad Oracle added this in RAC 19c.

I think the answer is D, because it allows the service to fall back to a preferred instance when it becomes available.
