OCI App Integration Pro (1Z0-1042-25) study plan

Map the Oracle Cloud Application Integration architecture layers (design-time canvas, runtime service engine, message pipeline, agent/connectivity layer) into a one-page diagram you draw from memory

Distinguish app-driven vs scheduled orchestration and list at least four trigger types with the scenario each fits

Compare orchestration styles (basic routing, scheduled orchestration, app-driven, publish/subscribe) and pick the correct style for three sample business scenarios

Walk through the lifecycle of a message from trigger to response and identify where mapping, routing, and callouts sit in that flow

Build a scheduled orchestration integration that reads from one source, transforms the payload, and writes to a second endpoint in a sandbox

Implement switch-based branching and a for-each loop over a repeating element inside the same integration

Author XSLT mapping rules for conditional logic, string manipulation, and date format conversion without relying on default auto-mapping

Debug at least three mapping failures (missing namespace, cardinality mismatch, wrong date pattern) and record the fix for each

Create reusable lookup tables and apply them in a mapping to translate coded values between systems

Configure a global fault handler and a scope-level fault handler, and force an error to verify which one fires

Add a callback or notification step on the error path and confirm the notification payload contains the fault details

Convert a flat structure into a hierarchical payload and validate the output against a sample schema

Provision and configure at least three connection types (REST, SOAP, and a file or FTP style adapter) and test each connection successfully

Install and register a connectivity agent, then route one integration through the agent to an on-premises-style endpoint

Configure connection retry and timeout properties and observe behavior when the target is unreachable

Design a callout pattern where a secondary service enriches the primary response, with a fallback when the callout fails

Compare basic authentication, OAuth client credentials, and OAuth authorization code, and select the right one for four described scenarios

Configure an OAuth-based connection end to end, including token endpoint details, scope, and credential storage in the credential store

Set up role-based access so a second user can view but not edit an integration, and verify the restriction

Explain how credentials are referenced at runtime versus stored at design time, and list three practices that avoid leaking secrets into logs

Locate and interpret activity stream entries, runtime instance details, and payload traces for a completed and a failed run

Reproduce three distinct failure classes (mapping error, connection timeout, authentication rejection) and match each to its log signature

Build a small error-handling matrix mapping failure class to detection point, handler, and recovery action

Use tracking variables or audit fields to trace a single record across a multi-step integration

Package an integration with its dependencies and export/import it into a second environment

Version an integration, activate the new version, and describe how activation and deactivation affect in-flight instances

Create a connection and integration that reference environment-specific values, and adjust them during promotion

Draft a promotion checklist covering export, dependency resolution, credential rebinding, activation order, and smoke test

Take two full timed practice runs and score each domain separately to expose weak areas

Re-drill the two lowest-scoring domains using your own notes and cheat sheets rather than new material

Rewrite your architecture, mapping, and security cheat sheets into a single condensed final review sheet

Re-explain fault handling, OAuth selection, and promotion order aloud without notes to confirm retention
