Oracle Cloud Infrastructure Developer Professional: Hands-on Workshop — Lesson 3: Events, Streaming, Queues, Notifications, and Data Integration

Learning Objectives

• Explain the purpose and operating context of Events rules, event types, targets, filtering, and delivery behavior.
• Apply Streaming partitions, producers, consumers, offsets, and retention and Queue concepts, visibility, retries, dead-letter handling, and idempotency in a controlled environment.
• Validate outcomes and troubleshoot risks involving Notifications, object events, database integration, and failure recovery.

Detailed Topics

• Events rules, event types, targets, filtering, and delivery behavior
• Streaming partitions, producers, consumers, offsets, and retention
• Queue concepts, visibility, retries, dead-letter handling, and idempotency
• Notifications, object events, database integration, and failure recovery

Instructor Demonstration

Demonstrate Events rules, event types, targets, filtering, and delivery behavior for an event-driven order application implemented and deployed through OCI developer services; capture the exact configuration, code, command, transaction, query, dashboard, model, schedule, or report evidence that proves the expected result.

Hands-On Exercise

Complete a controlled Oracle Cloud Infrastructure Developer Professional: Hands-on Workshop exercise covering Streaming partitions, producers, consumers, offsets, and retention and Queue concepts, visibility, retries, dead-letter handling, and idempotency; introduce an exception involving Notifications, object events, database integration, and failure recovery, diagnose it from evidence, apply the smallest reversible correction, and rerun acceptance checks.

1. Confirm scope, prerequisites, identities, dependencies, data, risks, and expected outcome.
2. Perform the course-specific configuration, development, administration, analysis, or business-process workflow.
3. Capture commands, settings, records, logs, screenshots, reports, metrics, or test results.
4. Compare the observed result with acceptance criteria and document corrective or preventive action.

Scenario Analysis

• Identify the technical or business decision and the stakeholders affected by it.
• Compare security, performance, reliability, compliance, cost, usability, and support trade-offs.
• Define rollback, recovery, communication, evidence, ownership, and escalation requirements.

Troubleshooting Guidance

Diagnose issues involving Events rules, event types, targets, filtering, and delivery behavior, Streaming partitions, producers, consumers, offsets, and retention, Queue concepts, visibility, retries, dead-letter handling, and idempotency, Notifications, object events, database integration, and failure recovery without making an unverified production change. Separate symptoms from causes, gather time-correlated evidence, test a reversible hypothesis, validate the correction, and record recurrence controls.

Validation Checklist

• The requirement, environment, inputs, dependencies, and expected result are documented.
• The result is reproducible and supported by product-specific evidence.
• Normal, boundary, failure, security, performance, and operational conditions are reviewed.
• Exceptions, rollback, ownership, support actions, and the next improvement priority are recorded.

Lesson Outcome

Learners can apply Events, Streaming, Queues, Notifications, and Data Integration in a realistic Oracle Cloud Infrastructure Developer Professional: Hands-on Workshop scenario and defend the result with documented evidence.
