8.9.2 Download and Update the Java JDK Package

Depending on your current environment, you can use one of three procedures to download and update the JDK package.

Using YUM and Unbreakable Linux Network (ULN) is only supported for Oracle Exadata on-premise database servers running Oracle Linux. It is not supported for storage servers or Oracle VM environments, either management domains (dom0) or user domains (domU).

Use one of the following methods to download and update the JDK package:

• Using YUM and ULN to Update the JDK Package on Database Servers
  If the database servers for your on-premise Oracle Exadata are running Oracle Linux 6 or later, then you can use YUM and Unbreakable Linux Network (ULN) to simplify the update process.
• Manually Update the JDK Package on Oracle Exadata System Software versions 12.1.2.1.0 to 12.1.2.2.0
  Update the JDK 7 package to the latest release by downloading the latest version of the package and using the rpm utility to install it.
• Manually Update the JDK Package on Oracle Exadata System Software Release 12.1.2.2.1 and Later
  Update the JDK 8 package to the latest release by downloading the latest version of the package and using the rpm utility to install it.
