Can EBS Nodes Be at Different Operating System Levels?
Oddly, a category of EBS architecture questions that I’d thought long-settled is starting to reemerge. I’ve recently seen several queries along the lines of:
- Can EBS database nodes and application tier nodes be on different operating systems?
- Can multiple EBS database nodes be on different operating systems or levels?
- Can multiple EBS application tier nodes be on different operating systems or levels?
Here are the answers to these questions:
1. Can EBS database nodes and application tier nodes be on different operating systems?
Yes. In some cases, the operating systems certified for EBS database nodes cannot be run on the application tier. These are called “database tier only” certifications. It is quite common to see this configuration, especially in large EBS environments.
2. Can multiple EBS database nodes be on different operating systems or levels?
No. From our “Installation Guide: Using Rapid Install” documentation:
“All database tier nodes must be at the same operating system patch level.”
3. Can multiple EBS application tier nodes be on different operating systems or levels?
No. From our “Installation Guide: Using Rapid Install” documentation:
“All application tier nodes must be at the same operating system patch level.”
Here’s a screenshot from our EBS 12.2 documentation (emphasis in red):

Webcast: “Managing Oracle E-Business Suite Auditing and Security”
Oracle University has a large number of free recorded webcasts for Oracle E-Business Suite. One of the essential webcasts on security that all EBS sysadmins should review is:
Eric Bing, Senior Director Product Development and Elke Phelps, Senior Principal Product Manager share recommendations for auditing, monitoring and securing your Oracle E-Business Suite environment and sensitive data. Configuration guidelines for monitoring and auditing activity in your Oracle E-Business Suite application and database will be provided. The session will provide an overview of our secure configuration guidelines, updates to the secure configuration scripts, and optional security integrations. Also shared is a summary of some of the new security features available in Oracle E-Business Suite 12.2 including enhancements for proxy user functionality and how to reduce your attack surface by reducing cookie scope, allowed JavaServer Pages (JSPs), and external redirects. This material was presented at OOW 2015.

Enabling an EBS Global Diagnostics Trace
Oracle E-Business Suite provides several types of logs. One of the tools you can use is the Logging Framework, which allows you to collect and view log messages in Oracle Applications Manager. The Logging Framework collects debug messages, errors, and alerts.
A Global Diagnostics Trace can help you diagnose issues if errors occur when users click a button or select an option. It’s a targeted trace that can be run per user, thereby minimizing the impact on the overall performance of your environment. This kind of trace is also known as an FND Diagnostics Trace or Oracle Applications Logging.
You can find a quick summary of steps to enable a Global Diagnostics trace here:
- How to Collect an FND Diagnostics Trace (aka FND:Debug) (Note 372209.1)
There’s lots more information about more-powerful logging options in the following manuals:
- Logging Features in Oracle E-Business Suite 12.2 (EBS 12.2 Maintenance Guide)
- Logging (EBS 12.1 System Administrator’s Guide)
