What are the typical challenges faced by an Oracle RAC DBA when managing high-availability databases?

As an Oracle RAC DBA, one of the main challenges is ensuring continuous high availability while performing maintenance, upgrades, or troubleshooting node failures. You'll regularly coordinate with network, storage, and application teams to resolve issues quickly and minimize downtime. Balancing performance tuning, managing cluster resources, and monitoring for split-brain scenarios are all critical tasks. Proactive communication and strong problem-solving skills help you succeed in this collaborative and dynamic environment.
