In a RAC environment, which background process is primarily responsible for coordinating the Global Cache Service and managing block transfers between instances?
A critical disk in an ASM disk group with NORMAL redundancy has failed. What is the default time window before ASM automatically drops the failed disk and begins full rebalancing?
