B Updating the JDK After Installing and Configuring an Oracle Fusion Middleware Product
Consider that you have an unsupported JDK version installed on your machine.
When you install and configure an Oracle Fusion Middleware product, the
utilities, such as Configuration Wizard (config.sh|exe
), OPatch, or RCU
point to a default JDK. The supported JDK version for this release is jdk17.0.12 and it carries security enhancements and bug
fixes. You can upgrade the existing JDK to a newer version, and can have the complete
product stack point to the newer version of the JDK.
You can maintain multiple versions of JDK and switch to the required version on need basis.
- About Updating the JDK Location After Installing an Oracle Fusion Middleware Product
The binaries and other metadata and utility scripts in the Oracle home and Domain home, such as RCU or Configuration Wizard, use a JDK version that was used while installing the software and continue to refer to the same version of the JDK. The JDK path is stored in a variable called JAVA_HOME which is centrally located in .globalEnv.properties file inside theORACLE_HOME/oui
directory.
