Common Multi-Step Flows

Task	Recommended Sequence
Diagnose a slow query	explain-plan → wait-events → optimizer-stats → awr-reports
Plan a migration	migration-assessment → oracle-migration-tools → source-specific migrate-*.md → migration-cutover-strategy
Build RAG on Oracle Database	ai-profiles → vector-search → dbms-vector
Build a Java JDBC service	java-oracle-jdbc → java-oracle-jdbc/dependencies → java-oracle-jdbc/connections → java-oracle-jdbc/sql → java-oracle-jdbc/pooling-production
Perform agent-safe schema change	schema-discovery → destructive-op-guards → idempotency-patterns → schema-migrations
Set up AI-driven database access via MCP	sqlcl-basics (save connections) → security/privilege-management (least-privilege user) → sqlcl-mcp-server (configure + start)
