Diagnose and manage Alibaba Cloud databases through natural language. Use when users need to troubleshoot database performance issues (high CPU, slow queries, abnormal connections, lock waits), check instance status, analyze disk space, optimize SQL, run health inspections, or detect security baseline violations. Supports RDS (MySQL/PostgreSQL/SQL Server), PolarDB, MongoDB, Redis (Tair), and Lindorm. Trigger this skill even for casual descriptions like "my database is slow", "can't connect to the database", "help me check this SQL", or "database disk is almost full". Also suitable for consulting Alibaba Cloud-specific database features (e.g., PolarDB Serverless, DAS autonomy capabilities) and comparing product differences (RDS vs PolarDB). Do NOT use this skill for general SQL tutorials, non-Alibaba Cloud databases, or local database administration.
Huawei Cloud RDS (Relational Database Service) full-scenario intelligent service covering all database engines (MySQL, PostgreSQL, SQL Server, MariaDB, GaussDB for MySQL, TaurusDB). Provides six capability domains: (1) Basic intelligent Q&A for RDS product features, best practices, and specifications; (2) SQL statement performance optimization with slow log analysis, top SQL, execution plan guidance, and index recommendations; (3) Database instance daily O&M including health inspection, restart, flavor resize, disk expansion, primary-standby switchover, and read replica management; (4) Online fault localization and troubleshooting via error logs, replication status, connection diagnostics, and recovery time window; (5) Parameter tuning with parameter group management, modification suggestions, and performance parameter adjustment guidance; (6) Backup and recovery guidance including backup policy management, manual backup creation, restore to new/existing instance, and point-in-time recovery.
