Oracle Integration Cloud (Gen3): File Polling Using FTP Trigger

Naveen — Sat, 02 May 2026 08:46:54 +0000

Automate file‑based integrations without custom schedulers (OIC Gen3 24.10+)

File‑based integrations are still extremely common—daily CSV extracts, XML drops from legacy systems, or batch partner feeds over FTP/SFTP.

Before Oracle Integration Cloud (OIC) Gen3 24.10,
triggering an integration when a file arrived often required:

Gen3 introduced a native File‑Polling trigger and it simplifies everything.

In this post, I’ll walk through how to use the new FTP File Polling trigger, when to use it, and what to watch out for.

When Should You Use File Polling?
Use this feature if:

Typical use cases:

What’s New in OIC Gen3 24.10+
With the FTP File‑Polling trigger, you can:

Step‑by‑Step: Configuring File Polling in OIC

1. Verify OIC Version
Ensure your instance is:

Oracle Integration Cloud Gen3 – 24.10 or later

File polling is not available in earlier Gen3 builds.

2. Configure FTP / SFTP Connection
Create or reuse an FTP adapter connection with Trigger & Invoke role:

Test the connection before proceeding.

3.Use the File‑Polling Trigger
While creating the integration:

You’ll configure:

Polling frequency (e.g., every 5 minutes)
Source directory
Filename pattern (e.g., *.csv)
Schema type (CSV / XML)
Optional sample file upload for schema generation This eliminates the need for a separate file‑server read step.

4. Configure File Handling Behavior
You can define what happens after the file is read:

📦 Archive the file
🗑️ Delete after successful read
🚫 Reject invalid files
⚠️ Ignore delete errors to prevent retries

This is extremely useful for idempotency and cleanup.

5. Design the Integration Flow
After the trigger:

Parse file content using the generated schema
Route data to downstream systems
Apply validations and transformations
Handle errors using reject logic

The file content is already available as the payload—no manual streaming required.

6. Test with a Proof of Concept (POC)
Before production:

7. Deploy & Monitor
Once verified:
