In which scenario should shadow clones be explicitly disabled?

C. When deploying an Oracle RAC database:

Shadow clones should be explicitly disabled when deploying an Oracle RAC database. Oracle RAC requires highly consistent and low-latency storage access, and enabling shadow clones can introduce additional latency and potential inconsistencies that are unsuitable for such databases.

Shadow clones are designed to enhance performance for read-heavy workloads by caching frequently accessed data locally. However, Oracle RAC’s stringent requirements for data consistency and latency make this feature inappropriate for its deployment.
