Oracle Integration Service Limits

=======================================================

Understanding service limits is very important while designing integrations in Oracle Integration Cloud (OIC).

Many performance and timeout issues occur because we don’t consider payload size, adapter limits, or execution time constraints during design.

Here’s a quick comparison of key limits:

=======================================

REST Adapter payload limits

SOAP XML payload size

 FTP read/download limits

Stage file processing limits

Connectivity Agent limits

Timeout configurations (Sync / Async / Scheduled)

Active integration limits

Key Highlights:

===============

Synchronous timeout: 300 seconds

Asynchronous & Scheduled timeout: 6 hours

Outbound adapter timeout: 240 seconds

JavaScript timeout: 15 seconds

Gen 3 supports higher payload limits compared to Gen 2 in many areas

Always design integrations considering:

Large file handling strategy (chunking / stage file)

Async patterns for long-running processes

Agent payload restrictions

Base64 and email size limits

Proper architecture planning helps avoid runtime failures and improves performance.
