OIC 26.10 shipped the MCP Gateway in September, and I have been reading through how it is meant to work. Instead of pointing every AI agent straight at every MCP server (OIC-hosted or third-party), agents connect to one gateway endpoint. The gateway handles identity, tool filtering, policies (Oracle’s demo shows tool filter, PII and business rule policies), credential resolution and audit.
What I like on paper: agents do not hold downstream credentials, and you can expose only approved tools instead of a whole server. What I am still unsure about, because it is a first iteration:
If you have tried it in a test tenant, share what you found. If you have not, tell me which integration you would expose to an agent first, and which one you would never expose without a human approval step.

Just published a new beginner-friendly guide on Oracle BI Publisher (BIP) Reports in Oracle Fusion.
It covers the complete flow from scratch — Data Model, SQL Data Set, Parameters, LOVs, XML, RTF templates, report creation, and how BIP is used with OIC.
If you're starting with Oracle Fusion Technical, this should give you a solid foundation.

What Oracle Fusion topic should we cover next?
Spent some time going through Oracle's AI Agent Studio docs, the public GitHub repo, and the certification blueprints. A few things genuinely surprised me:
1. The security model is the headline, not the AI. Agents inherit Fusion's existing role-based access control automatically. A manager's agent sees team compensation data because the manager can — an IC's agent can't, for the same reason. No separate security layer to build or audit.
2. There's a hard 60-second response limit on Workflow Team interactions. If you're chaining multiple LLM calls plus an External REST invocation, that ceiling is a real architectural constraint — same energy as OIC's thread timeout limits.
3. The five tools (Business Object, Document, Email, Deep Link, External REST) feel very familiar if you come from OIC — basically adapters and actions with different names. And OIC 26.07 added a native A2A action to invoke Agent Studio agents directly from integration flows, so the two are clearly converging.
4. Two certifications already exist — 1Z0-1145-1 (Foundations Associate) and 1Z0-1155-2 (Developer, 90 min / 50 questions / 68% pass, validated against 26A).
Has anyone else been burned by OIC's "Abort" button in production?
Learned this one the hard way and I'm curious if others have hit it too.
An engineer on a support team I worked with bulk-selected an entire Errors page in OIC and hit Abort — to "clean up the dashboard." Those messages were gone. Permanently. Aborted instances can't be recovered by any means, and the source system had already marked them as sent.
That's data loss created by a UI button, and OIC gives you no warning beyond a line in the docs saying don't discard a message you want to resubmit.

🎯 Oracle Interview Reality Check
When preparing for Oracle Fusion or OIC interviews, most professionals focus only on technical questions.
But many interviewers spend more time discussing:
• Real project challenges
• Production issues
• Integration failures
• Performance bottlenecks
• Go-live experiences
Technical knowledge gets your foot in the door.
Real project experience often gets you the offer.

⚠️ Oracle Integration Cloud Professionals
Many teams have migrated to OIC Gen3.
But have they actually changed the way they work?
We've seen projects where teams are still:
• Building integrations from scratch every time
• Relying heavily on manual monitoring
• Using batch jobs where real-time integrations make more sense
• Missing opportunities for reuse and automation
Technology upgrades only create value when working practices evolve too.
🤔 What's the biggest improvement your team adopted after moving to OIC Gen3?
