Serverless ETL using OCI Data Integration — Lesson 3: Integration Tasks, Pipelines, Scheduling, Dependencies, and Error Handling

Learning Objectives

• Trace the Oracle objects, services, rules, reports, interfaces, or code used in integration tasks, pipelines, scheduling, dependencies, and error handling.
• Configure a hands-on implementation or diagnostic sequence without bypassing approvals.
• Defend reproducibility by comparing expected and actual evidence.

Detailed Topics

• Integration Tasks
• Pipelines
• Scheduling
• Dependencies
• Error Handling
• ownership, prerequisites, data, and acceptance criteria for integration tasks, pipelines, scheduling, dependencies, and error handling
• security, control, integration, performance, recovery, and support implications

Instructor Demonstration

Demonstrate integration tasks, pipelines, scheduling, dependencies, and error handling within a serverless ETL pipeline ingesting source data, applying governed transformations, loading a target, and recovering failed runs. Use representative data and capture task runs, pipeline history so another practitioner can verify the result.

Hands-On Exercise

Complete a controlled Serverless ETL using OCI Data Integration activity focused on integration tasks, pipelines, scheduling, dependencies, and error handling. Introduce a realistic case of bad transformation logic, isolate its cause, apply a reversible correction, and rerun the acceptance checks.

1. Record the requirement, environment, identities, dependencies, data, controls, and expected result.
2. Perform the workflow and capture course-specific evidence before and after each material change.
3. Test normal, boundary, failure, security, reconciliation, recovery, and operational conditions.
4. Document the root cause, correction, rollback, owner, support action, and next improvement priority.

Scenario Analysis

• Map the end-to-end flow from source input through Oracle processing to the final output.
• Locate the control point most likely to prevent or expose bad transformation logic.
• Recommend monitoring, escalation, and handover requirements for production support.

Troubleshooting Guidance

When integration tasks, pipelines, scheduling, dependencies, and error handling does not produce the expected result, confirm scope, effective dates, identities, data context, dependencies, and recent changes. Review the most relevant task runs, pipeline history before editing configuration. Test one reversible hypothesis at a time, verify recovery, and confirm that the fix does not create bad transformation logic elsewhere.

Validation Checklist

• Prerequisites, ownership, data context, settings, and expected outcomes are documented.
• The result is reproducible and supported by task runs, pipeline history.
• Security, controls, data quality, integration, performance, recovery, and support conditions are reviewed.
• Exceptions, corrective action, rollback, approvals, monitoring, and handover are recorded.

Lesson Outcome

Learners can apply Integration Tasks, Pipelines, Scheduling, Dependencies, and Error Handling in a realistic Serverless ETL using OCI Data Integration situation and defend the result with course-specific evidence.
