description

Oracle Database guidance for SQL, PL/SQL, SQLcl, ORDS, administration, app development, performance, security, migrations, and agent-safe database workflows. Use when the user asks to write, edit, rewrite, review, format, debug, tune, or explain SQL; create or refactor PL/SQL; use SQLcl, Liquibase, ORDS, JDBC, node-oracledb, Python, Java, .NET, or database frameworks; troubleshoot queries, sessions, locks, waits, indexes, optimizer plans, AWR, ASH, migrations, schemas, users, roles, privileges, backup, recovery, Data Guard, RAC, multitenant, containers, monitoring, auditing, encryption, VPD, or safe agent database operations.

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
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)
