Information in this document applies to any platform.


This document will clarify the intentions between the Oracle WebLogic Server (WLS) and Oracle Fusion Middleware (FMW) Certification Guides when FMW 14c, 12c, and 11g products are listed together. Primarily, there are two confusing areas that need an explanation:


Certification Check

To understand the intention of the certification, it should be noted which Certification Guide being read, (e.g. 11.1.1, 11.1.2, 12.1.3,, 14.1.1, or newer). When using two releases together, both should be checked, as the context may be different in the other (or may not reciprocate). Note the newer certifications can consider the older versions, but the older tested and written certifications cannot consider the newer versions. This can sometimes help understand the supported use cases. Below are the locations of each certification matrix:

Key Points Within Certification Checks:

Interoperability and Compatibility

FMW 12.1.x Interoperability and Compatibility Guides provides more information to clarify the intentions for each release:

Interoperability and Compatibility Guides

WebLogic Server Compatibility (WLS 14.1.1 standalone) ( ( ( (
( (12.1.3) (12.1.2)

Except for 14.1.1, which is standalone, look for these or similar sections to confirm compatibility between FMW products:

2.2 Oracle WebLogic Server and Coherence Compatibility with Previous Releases
2.3 Oracle Fusion Middleware Infrastructure Compatibility with Previous Releases
2.4 Oracle HTTP Server Interoperability and Compatibility
2.6 Interoperability with Oracle Identity Management Products

Below is more detail to include all scenarios and versions involving the WLS Proxy Plugin:

Oracle WebLogic Server Proxy Plug-In

Oracle WebLogic Server Proxy Plug-In refers to a proxy plug-in module - available as a separate download - that works with a specific list of 3rd party Web Servers such as Apache HTTP Server, Oracle iPlanet Web Server, Microsoft Internet Information Server (IIS). Customers can use Oracle WebLogic Server Proxy Plug-In with these 3rd party Web Servers to front-end WebLogic Server deployments.  Oracle HTTP Server bundles this proxy plug-in as part of the product and refers to it as the 'mod_wl_ohs' module.

Always check the certification between releases by referring to certification and compatibility guides for the Oracle Fusion Middleware products and versions are being used. The Oracle WebLogic Server Proxy Plug-In is designed to be backward compatible with Oracle Weblogic Server versions, but not all Oracle Fusion Middleware "upper stack" products have been tested in every scenario. When using other Oracle Fusion Middleware products, using the newest WLS Plugin should be used only where documentation allows for the installed applications. For Oracle HTTP Server (OHS), mod_wl_ohs is included as the WLS Proxy Plug-In. When OHS installed with an Oracle Fusion Middleware product, is usually the expected and tested version for the installed applications. For third-party web servers (IIS, Apache, iPlanet), there are platform certifications and other things to consider before making substitutions.

More advanced topologies include a mix of FMW products are deployed to WLS, sometimes separate WLS installations, where a single entry point proxy is required to reach all applications. Checking the certification may result in difficulty reaching a solid conclusion of what is supported for an advanced topology.

After checking the certification and compatibility guides for your combinations, the following summarizes what is supported when considering use between releases:
