DBAgent: An RL-Based Agent for Autonomous Database Operations and Maintenance

Summary: DBAgent is an RL-trained autonomous O&M agent for Huawei DWS, integrating dynamic tool use, multimodal database telemetry, and Think–Act–Observe planning with Autopilot alerts. It learns intervention dynamics and handles drift, improving success 23% over the strongest baseline with ~5% hallucination. (summarized by gpt-5.6-luna on Aug 28 2026)
