Java Development Kit (JDK) Requirements

To run the installers in the 12 c 12.2.1.3.0, you must have a certified JDK already installed on your system. Most Fusion Middleware products are available as platform-generic distributions in .jar file format. Some products (for example, Oracle HTTP Server) have a .bin (for UNIX operating systems) or .exe (for Windows operating systems) installer. In the 12 c 12.2.1.3.0, the Fusion Middleware products, the platform-specific distributions no longer include and configure a JDK automatically.

At the time this document was published, the certified JDK was jdk1.8.0_131. For information about the latest certified JDKs, refer to the certification document for your software version listed in Oracle Fusion Middleware Supported System Configurations page.

Note:

It is a best practice to use a separate JDK location than the one installed on the system. One that you can manage and maintain with the Fusion Middleware products. See, Doc ID 1492980.1 How to Install and Maintain the Java SE Installed or Used with FMW 11g or 12c Products. This ensures that the Oracle Fusion Middleware software is using the proper version of the JDK software.

For example, if RCU cannot locate the proper JDK software, RCU will fail with the following error: Cannot Find the File javaw.
