Which three statements are true about the Global Resource Directory (GRD) in Oracle 19c RAC database and in Clustered ASM? (Choose three.)
Which three statements are true about the Global Resource Directory (GRD) in Oracle 19c RAC database and in Clustered ASM? (Choose three.)
The correct answers are based on the understanding of the Global Resource Directory (GRD) in Oracle 19c RAC databases and Clustered ASM. First, shadow GRD resources may exist in more than one database instance for a resource, indicating B is correct. Second, Clustered ASM has GRD resources distributed among all ASM instances, which makes C valid. Finally, RAC databases have GRD cache resources distributed among all the database instances and stored in the shared pool of each instance, confirming that G is also correct. The other options either misinterpret the storage locations or distributions of the GRD resources.
