Oracle Coherence 12c: Share and Manage Data in Clusters Ed 1.1 — Lesson 4: Security, Capacity, Performance, and Failure Recovery

Technical Scope

• cluster security, identity, authorization, TLS, access policy, and secret handling
• capacity planning, partition count, backup count, storage roles, and heap sizing
• JMX, metrics, tracing, load testing, hot partitions, and performance tuning
• member loss, site loss, split conditions, recovery drills, and support runbooks

Instructor Demonstration

The instructor traces cluster security, identity, authorization, TLS, access policy, and secret handling, then connects it to capacity planning, partition count, backup count, storage roles, and heap sizing. 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 capacity planning, partition count, backup count, storage roles, and heap sizing and JMX, metrics, tracing, load testing, hot partitions, and performance tuning. The exercise introduces a realistic exception related to member loss, site loss, split conditions, recovery drills, and support runbooks 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 JMX, metrics, tracing, load testing, hot partitions, and performance tuning, traceable proof for cluster security, identity, authorization, TLS, access policy, and secret handling, and a repeatable recovery path for member loss, site loss, split conditions, recovery drills, and support runbooks. Results must be understandable to both implementers and operational support teams.

Failure Analysis

Learners compare symptoms, logs, state, dependencies, and recent changes when member loss, site loss, split conditions, recovery drills, and support runbooks occurs. The final diagnosis must separate the immediate fix from the preventive control.

Practical Outcome

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