Oracle Database 19c: Multitenant Architecture — Lesson 3: Security, Backup, Recovery, and Resource Management

Technical Scope

• common/local privileges, roles, lockdown profiles, keystores, and auditing
• RMAN backup scope, PDB recovery, point-in-time recovery, and dropped PDB scenarios
• resource manager plans, shares, utilization limits, I/O controls, and runaway sessions
• security validation, recovery drills, service restoration, and evidence capture

Instructor Demonstration

The instructor configures and validates common/local privileges, roles, lockdown profiles, keystores, and auditing, then connects it to RMAN backup scope, PDB recovery, point-in-time recovery, and dropped PDB scenarios. The demonstration captures the exact configuration, transaction, command, query, log, or screen evidence needed to prove intended behavior and the applicable control boundary.

Applied Workshop

Learners execute a guided lab focused on RMAN backup scope, PDB recovery, point-in-time recovery, and dropped PDB scenarios and resource manager plans, shares, utilization limits, I/O controls, and runaway sessions. The exercise introduces a realistic exception related to security validation, recovery drills, service restoration, and evidence capture and requires a reversible correction supported by before-and-after evidence.

1. Confirm scope, identities, data, dependencies, controls, and expected result.
2. Perform the product-specific configuration or analysis and record exact steps.
3. Validate functional behavior, security, data integrity, and operational observability.
4. Introduce the defined failure condition, diagnose the cause, and apply a safe correction.
5. Document rollback, acceptance evidence, unresolved risk, and ownership.

Validation Standard

Acceptance requires accurate handling of resource manager plans, shares, utilization limits, I/O controls, and runaway sessions, traceable proof for common/local privileges, roles, lockdown profiles, keystores, and auditing, and a repeatable recovery path for security validation, recovery drills, service restoration, and evidence capture. Results must be understandable to both implementers and operational support teams.

Failure Analysis

Learners compare symptoms, logs, state, dependencies, and recent changes when security validation, recovery drills, service restoration, and evidence capture occurs. The final diagnosis must separate the immediate fix from the preventive control.

Practical Outcome

The completed output is a tested security, backup, recovery, and resource management implementation or analysis, with validation evidence, troubleshooting notes, rollback guidance, and a concise operational handover.
