PeopleSoft PeopleCode — Lesson 4: Debugging, tracing, error handling, performance, security, upgrade-safe customization, code review, testing, and migration

Learning Objectives

• Identify the configuration and data choices that shape Debugging, tracing, error handling, performance, security, upgrade-safe customization, code review, testing, and migration.
• Run normal and boundary tests and record the outcome in PeopleCode quality report and migration-ready change package.
• Separate root cause from symptom when investigating custom logic passing a happy-path test but failing after a delivered component change.

Detailed Topics

• Debugging
• Tracing
• Error handling
• Performance
• Security
• Upgrade-safe customization
• Code review
• Testing
• And migration
• Decision ownership, prerequisites, and acceptance evidence for Debugging, tracing, error handling, performance, security, upgrade-safe customization, code review, testing, and migration
• Relevant access, data, integration, performance, recovery, and support considerations

Instructor Demonstration

Using realistic data and role assignments, the instructor demonstrates Debugging, tracing, error handling, performance, security, upgrade-safe customization, code review, testing, and migration. Key checkpoints are captured in PeopleCode quality report and migration-ready change package, with discussion of alternatives, side effects, and the conditions required for an acceptable result.

Hands-On Exercise

Complete a guided task covering Debugging, tracing, error handling, performance, security, upgrade-safe customization, code review, testing, and migration. After establishing a working baseline, reproduce “custom logic passing a happy-path test but failing after a delivered component change,” isolate the responsible setting or data condition, apply a reversible fix, and update PeopleCode quality report and migration-ready change package with before-and-after proof.

1. Confirm scope, access, sample records, and acceptance criteria.
2. Perform the configuration or transaction using a controlled sequence.
3. Inspect outputs and downstream effects rather than relying on screen messages alone.
4. Close with a support note, preventive action, and reproducible validation step.

Scenario Analysis

• Clarify the business trigger, affected roles, required records, and acceptable result for Debugging, tracing, error handling, performance, security, upgrade-safe customization, code review, testing, and migration.
• Compare at least two implementation or correction choices and identify which evidence would distinguish them.
• Decide how PeopleCode quality report and migration-ready change package should be reviewed, approved, retained, and handed to the next owner.

Troubleshooting Guidance

When results from Debugging, tracing, error handling, performance, security, upgrade-safe customization, code review, testing, and migration are unexpected, first reproduce the issue with the same role, record, date, and transaction context. Inspect PeopleCode quality report and migration-ready change package, then test whether “custom logic passing a happy-path test but failing after a delivered component change” explains the evidence before changing configuration. Retest the corrected path and one unaffected path to guard against regression.

Validation Checklist

• Prerequisites and role permissions for Debugging, tracing, error handling, performance, security, upgrade-safe customization, code review, testing, and migration have been confirmed before execution.
• The result agrees with the expected values documented in PeopleCode quality report and migration-ready change package.
• Exceptions are explained with evidence rather than hidden by manual correction.
• The final record names the approver, monitoring point, and next improvement action.

Lesson Outcome

Learners can apply Debugging, tracing, error handling, performance, security, upgrade-safe customization, code review, testing, and migration, explain the decisions made, and defend the result with PeopleCode quality report and migration-ready change package.
