🚨 Introduction: Struggling With "Invalid Security" in OIC?
Oracle Integration Cloud (OIC) is powerful—but nothing derails your integration flows faster than the dreaded:
⚠️ “InvalidSecurity: Error in processing the WS-Security security header”
This error is frustrating, vague, and often pops up during connection setup or runtime. But don’t worry—this post walks you through why it happens and how to fix it for good.
🧠 What Does "Invalid Security" Actually Mean?
This error generally signals a security mismatch between OIC and the external service you're connecting to. Common culprits include:
-
❌ Incorrect authentication (username/password or OAuth tokens)
-
❌ Mismatched security policies
-
❌ Missing or outdated certificates
-
❌ Connectivity agent or network/firewall issues
✅ The FIX That Worked: Refreshing Connection Metadata
After extensive troubleshooting, here’s what fixed the problem:
🔧 Steps:
-
Go to Connections in your OIC dashboard.
-
Find the failing connection.
-
Click on the three dots (⋮) on the right side.
-
Choose "Refresh Metadata".
🧹 Refreshing metadata ensures OIC re-reads the target system’s latest security headers, WSDL, and policy information.
🧪 Root Causes and How to Solve Them
Here’s a quick reference guide on what might be going wrong and how to fix it:
| ⚠️ Cause | 🛠️ How to Fix It |
|---|---|
| Expired or invalid credentials | Double-check username/password or OAuth tokens. Avoid Basic Auth if MFA is enabled. |
| Security policy mismatch | Make sure OIC’s security policy matches what the target system expects. |
| Missing certificates | Upload needed SSL or intermediate certs (like msft.cer) to OIC’s trust store. |
| Connectivity agent config | Validate InstallerProfile.cfg and host resolution (/etc/hosts). Restart the agent. |
| Database adapter issues | Apply necessary DB patches (e.g., Patch 26482376) and confirm wallet configuration. |
| Network/firewall issues | Ensure no firewall or VCN rule is blocking your target URL. |
