CPU and memory auto-scaling in eBS

edited May 6, 2025 12:30PM in EBS on Oracle Cloud Infrastructure (MOSC) 4 commentsAnswered

R12.2 on Linux 64bit, 19c (with RAC for Prod)

My question is regarding auto-scaling of CPU and memory as being a feature in Cloud Compute.

How does this work in reality in eBS on Cloud ? For example, I have Production environments which are extremely low used during nights and weekends.

and I have non-Prod environments which are really unused even during some working days already.

How does this scaling work: does it scale back to zero ? (as I understood it could for CPU, not for memory though)

Does it shutdown services (middleware, database) ? Does it shutdown servers ?

How does "wake up" ? I'm not sure I understand, but if a database is down, and I try to connect, what software is going to tell me your connect attempt is triggering anything that is going to cause for a database to startup again ? The standard Oracle RDBMS software (for non-RAC) does not have this feature. So, how does that work ?

Howdy, Stranger!
