1 Introduction to Upgrading Oracle Fusion Middleware Infrastructure to 14c (14.1.2.1.0)

Upgrading to Oracle Fusion Middleware Infrastructure 14c (14.1.2.1.0) requires careful preparation and planning. Oracle provides tools and technology to automate much of the upgrade process.

About the Starting Points for an Oracle Fusion Middleware Infrastructure Upgrade

The primary focus of the upgrade procedures in this guide is to upgrade an existing 12c (12.2.1.4) domain and the Oracle Fusion Middleware component configurations in that domain to Oracle Fusion Middleware Infrastructure 14c (14.1.2.1.0).

You can upgrade to Oracle Fusion Middleware Infrastructure 14c (14.1.2.1.0) from Oracle Fusion Middleware Infrastructure 12c (12.2.1.4).

About Oracle Fusion Middleware Infrastructure

Oracle Fusion Middleware Infrastructure distribution, which is available as part of the Oracle Fusion Middleware 14c (14.1.2.1.0) release, provides a set of technologies and components similar to those provided by the Oracle WebLogic Server and Application Developer installers in 12c. The Infrastructure distribution combines the WebLogic Server and the Java Required Files (JRF) that are required to install other Fusion Middleware products.

Upgrading Security Store

Before upgrading the OPSS security store, it is important to back up the security store so that it can be recovered in case the upgrade fails.

For details about backing up the security store, see Backing Up and Recovering the OPSS Security Store.

The upgrade procedure varies depending on the type of security store you start from. The security store to be upgraded can be file-based, OID-based, or DB-based. Note that the procedures vary depending upon the type of source audit data store (file-based or DB-based).

For more information about upgrading security stores, see About the Security Store .

About Oracle Fusion Middleware Infrastructure Standard Topology

The steps to upgrade Oracle Fusion Middleware Infrastructure to 14c (14.1.2.1.0) depend on the existing production topology.

It is difficult to provide exact upgrade instructions for every possible installation. To solve this problem, this upgrade documentation provides detailed instructions for upgrading a typical Application Developer configuration. This typical topology is referred to as the standard upgrade topology.

Specifically, for the purposes of this guide, it is assumed that you have used Oracle WebLogic Server and the Application Developer 12c (12.2.1.4) software to configure a domain that contains a cluster of two managed servers, both of which are configured to support Oracle JRF and the deployment of Oracle ADF applications.

Your actual topology may vary, but the topology described here provide an example that can be used as a guide to upgrade other similar Application Developer topologies.

Note:

For additional information about the upgrade process and planning resources to ensure your upgrade is successful, see Preparing to Upgrade in Planning an Upgrade of Oracle Fusion Middleware.

The standard topology remains unchanged from 12c (12.2.1.4).

About Upgrade Restrictions

If you are using two or more Oracle Fusion Middleware products of the same or different versions in a single, supported, Oracle Fusion Middleware configuration, you must consider the interoperability and compatibility factors before planning the upgrade.

For a list of products and features available in Oracle Fusion Middleware Release 14.1.2.1.0, see Products and Features Available in Oracle Fusion Middleware in Understanding Interoperability and Compatibility.

When performing the upgrade of your hardware or software, verify that your Oracle Fusion Middleware software is certified to support the new operating system or computer hardware. For more information, refer to the following resources:

Upgrading Custom Applications Using Oracle JDeveloper

If you have deployed custom applications to an Oracle Fusion Middleware Application Developer domain, then the application deployments should function as they did in Oracle Fusion Middleware 12c (12.2.1.4) after the upgrade procedure is complete. However, if you want to take advantage of new Oracle Application Development Framework (Oracle ADF) features, download and install Oracle JDeveloper.

See Installing the Oracle JDeveloper Software in Installing Oracle JDeveloper.
