Analyzing Differences in Oracle Integration Cloud Artifacts

Introduction

When developing integrations in Oracle Integration Cloud (OIC), artifacts are created with encapsulated metadata definitions. This script helps analyze differences between artifacts, making it easier to understand changes between versions.

Pre-Requisites

Install these Python libraries:

pandas
tabulate

The code

You can find the code here: oic_python_compare.py

You can execute the code changing the name of the artifacts:

You can change the code to accept parameters if you intend to use with any automation process.

How the Script Works

The script compares two .iar artifacts by extracting and analyzing their contents. The key functionalities include:

Creating Temporary Copies:
- Copies the original artifacts into a temporary directory to avoid modifying the original files.
Extracting Files:
- Converts .iar files into .zip format and extracts them into designated folders.
Renaming Versioned Folders:
- Standardizes folder names by replacing version numbers with _VERSION to simplify comparisons.
Comparing Files:
- Analyzes different file formats, including:
  - Text files: Compares line-by-line differences.
  - Properties files: Identifies key-value changes.
  - JSON files: Recursively checks for modifications in structured data.
  - XML files: Compares attributes, elements, and text content.
Comparing Directories:
- Iterates through both artifact directories and reports missing or modified files.
Generating a Comparison Report:
- Outputs a structured table with detected differences.
Cleaning Up Temporary Files:
- Removes extracted and temporary files after execution.

Practical Use Case

Imagine two versions of an integration:

MIGRATE_TO_APIGW_01.00.0003.iar
MIGRATE_TO_APIGW_01.00.0007.iar

By running the script, developers can identify exactly what changed between these versions, aiding in debugging and version control.

Conclusion

This script provides an automated way to compare Oracle Integration artifacts, saving time and reducing errors when managing integration changes. By identifying modifications in metadata, configurations, and logic, teams can ensure seamless updates and deployments.
