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 → java-oracle-jdbc/providers (cloud secrets, tracing, Spring, Pkl)
Perform agent-safe schema change	schema-discovery → destructive-op-guards → idempotency-patterns → schema-migrations
Set up AI-driven database access via MCP	security/deep-data-security (end-user authorization) → sqlcl-basics (save connections) → sqlcl-mcp-server (configure + start)
Set up an Oracle Vector SDK database deployment	vecdb-provisioning → Oracle Vector SDK Quick Start → Prepare an AI Database
Build vector-based applications for semantic search, RAG, or recommendations using Oracle Vector SDK's fixed-schema APIs through the Python SDK, REST, or PL/SQL	vecdb-architecture → vecdb-api-reference → relevant capability file (vecdb-models, vecdb-vector-tables, vecdb-search, or vecdb-indexes)
