Refer to the following sections for information on Oracle Fusion Middleware14c (14.1.2.0.0) compatibility with previous Oracle Fusion Middleware releases:

• Compatibility with Oracle Fusion Middleware 14c (14.1.2.0.0)
  

Oracle Fusion Middleware14c (14.1.2.0.0) supports specific database versions for hosting the required Oracle Fusion Middleware product and component schemas and for other specific product features.

The certification information on the Oracle Technology Network provides information about the specific database versions supported by Oracle Fusion Middleware. For more information on using the certification information, see Using the Oracle Certification Matrixes.

However, in some cases, an Oracle Fusion Middleware feature or component requires a more specific database version or a specific database feature that is available in a particular database release.

The following sections describe some of those specific features and database requirements:

• Oracle Database Interoperability Considerations
  
• Java DB Interoperability Considerations
  
• Additional Database Interoperability Considerations
  

This section summarizes the most common interoperability scenarios for Oracle HTTP Server and other Oracle Fusion Middleware components. The information in this section was accurate as of the publishing of this document.

For complete information about the interoperability of Oracle HTTP Server, see the certification information available on the Oracle Technology Network. For more information, see Using the Oracle Certification Matrixes.

Before you start, consider the following:

• Certification is based on the use of the WLS Proxy Plugin as documented in Fusion Middleware Using Oracle WebLogic Server Proxy Plug-Ins. Oracle HTTP Server may also be used as a proxy to another Oracle HTTP Server (same or different version) using mod_proxy, as documented in Apache HTTP Server and Third-party Modules in Oracle HTTP Server in Fusion Middleware Administering Oracle HTTP Server.

• Interoperability between versions (such as between Oracle HTTP Server 12c and Oracle Fusion Middleware 14c) are supported only when the products are installed in separate Oracle homes. In general, Oracle does not support the installation of products of different versions in the same Oracle home. For more information, see Oracle Home and Domain Extension Interoperability.

• Support for any combination is limited by features and until the end of support of the lowest version. For best results, customers are encouraged to use the latest version where possible. For example, during a migration period, use Oracle HTTP Server 14c (14.1.2.0.0) instead of separate WebLogic Server 10.3.6 and 14c (14.1.2.0.0) environments.

• Oracle HTTP Server 14c includes WebGate 14c, which can be used to integrate Oracle WebLogic Server or Oracle Fusion Middleware Infrastructure with Oracle Access Manager. For more information, see Interoperability with Oracle Access Management and Oracle Identity Governance. For more details on this combination, see Interoperability with Oracle Identity Management Products.

You can install OAM and OIG using the same product distribution (fmw_14.1.2.0.0_idm.jar). To install OID and OUD, use the platform-specific OID and fmw_14.1.2.0.0_oud.jar distributions respectively.

This section provides information about Oracle Identity Management Interoperability with Oracle Fusion Middleware 14c:

• Interoperability with Oracle Access Management and Oracle Identity Governance
  
• Interoperability with Oracle Internet Directory and Oracle Unified Directory
  
• Interoperability with Oracle Analytics Publisher
  

The following sections provide information about the interoperability of Oracle Fusion Middleware products when installing products in an Oracle home and when extending existing Oracle WebLogic Server domains:

• Oracle Home Interoperability
  
• Domain Extension Interoperability
  

When you upgrade to Oracle Fusion Middleware 14c, or if you apply any patches on an existing Oracle Fusion Middleware, you should consider the impact on your custom applications, such as:

• Applications written using JDeveloper

• Applications using any other IDE, but also using any of the Oracle Fusion Middleware public Java APIs.

Specifically, the information in this section applies in the following situations:

• If you have created custom applications that you have deployed on Oracle Application Server 10g or Oracle Fusion Middleware 11g or Oracle Fusion Middleware 12c.

• If you have created or if you maintain client applications that interact with applications you deployed on Oracle Application Server 10g or Oracle Fusion Middleware 11g or Oracle Fusion Middleware 12c.

Oracle attempts to support binary and source-level compatibility between the current version of Fusion Middleware and patch set updates applied to it. Where incompatibilities arise with public interfaces, they are documented in the related API reference guides. For more information about APIs, see Reference and APIs in the Oracle Fusion Middleware14c (14.1.2.0.0) documentation library.

Oracle recommends that you ensure the business applications adopting new versions or upgrades are tested through your normal release process to ensure there are no regressions.

In general, applying Oracle Fusion Middleware patch sets should require no additional changes to your custom or client applications. When upgrading, however, you should expect some changes.

For more information about compatibility with WebLogic Server, see WebLogic Server 14.1.2.0.0 Compatibility with Previous Releases in Upgrading Oracle WebLogic Server.

Oracle Data Integrator is designed to be used with specific Oracle SOA Suite, Oracle Enterprise Data Quality (EDQ), and Oracle GoldenGate software releases. The following table shows which releases of these software products can be used with Oracle Data Integrator 14c (14.1.2.0.0).

The asterisk (*) indicates that the software is interoperable with releases later than one shown.

Oracle Enterprise Data Quality (EDQ) is designed to be used with specific releases of the EDQ Address Verification Server and EDQ Customer Data Services Pack. The following table shows which releases of these software products can be used with EDQ 14c (14.1.2.0.0).

The asterisk (*) indicates that the software is interoperable with releases later than one shown.
