Oracle Database 19c: RAC Administration Workshop — Lesson 2: Installation, ASM, Networks, Services, and Policy Management

Technical Scope

• installation planning, user groups, storage, kernel, time, network, and prerequisite checks
• ASM disk groups, redundancy, failure groups, rebalance, ACFS, and capacity monitoring
• database creation, instances, redo threads, undo, services, and preferred/available nodes
• administrator- and policy-managed deployment, server pools, validation, and rollback

Instructor Demonstration

The instructor diagnoses installation planning, user groups, storage, kernel, time, network, and prerequisite checks, then connects it to ASM disk groups, redundancy, failure groups, rebalance, ACFS, and capacity monitoring. 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 build and verify an implementation covering ASM disk groups, redundancy, failure groups, rebalance, ACFS, and capacity monitoring and database creation, instances, redo threads, undo, services, and preferred/available nodes. The exercise introduces a realistic exception related to administrator- and policy-managed deployment, server pools, validation, and rollback 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 database creation, instances, redo threads, undo, services, and preferred/available nodes, traceable proof for installation planning, user groups, storage, kernel, time, network, and prerequisite checks, and a repeatable recovery path for administrator- and policy-managed deployment, server pools, validation, and rollback. Results must be understandable to both implementers and operational support teams.

Failure Analysis

Learners compare symptoms, logs, state, dependencies, and recent changes when administrator- and policy-managed deployment, server pools, validation, and rollback occurs. The final diagnosis must separate the immediate fix from the preventive control.

Practical Outcome

The completed output is a tested installation, asm, networks, services, and policy management implementation or analysis, with validation evidence, troubleshooting notes, rollback guidance, and a concise operational handover.
