Updating to the Latest Java Patch Level

Each release of Oracle Enterprise Performance Management System installs the Java 8 JDK, which incorporates the highest available patch level at the time of release. Between releases, you might be required to patch the JDK.

After installing and configuring EPM System, follow these steps to update your existing version of the JDK to a more recent version. Perform these steps on all Middleware Home directories for the EPM System deployment and on all EPM Oracle instances across all hosts.

The source JDK refers to the JDK an existing installation is configured to use. The target JDK version is the version that the installation is being updated to use.

Check with Oracle Support for download locations for newer Java 8 distributions.

Updating Java for EPM System Release 11.2.5+ (Windows and Linux)

Starting with EPM System Release 11.2.5, JDK8 and JRE8 are installed to a directory where the directory name does not include the complete version of Java.

For example,

JDK: Oracle\Middleware\jdk

JRE: Oracle\Middleware\EPMSystem11R1\common\JRE\Sun\1.8.0

To update Java:

1. Stop all EPM System services.
2. Perform these actions on MIDDLEWARE_HOME:
   1. Rename the current JDK folder to Oracle\Middleware\jdk.save.
   2. Install the target JDK into Oracle\Middleware\jdk.
   3. If there is a JRE installed in Oracle\Middleware\EPMSystem11R1\common\JRE\Sun\1.8.0:
      1. Rename the JRE folder to 1.8.0.save.
      2. Install the target JRE to Oracle\Middleware\EPMSystem11R1\common\JRE\Sun\1.8.0.
3. Start all EPM System services.

If you’re using the default Java keystore to store public/private certificates, make sure to copy it from the old JRE location to the new location after completing the patching:

Oracle\Middleware\jdk\jre\lib\security\cacerts

Oracle\Middleware\EPMSystem11R1\common\JRE\Sun\1.8.0\lib\security\cacerts
