If you are upgrading from an earlier release of Tivoli® Monitoring to V6.3, you already have a correctly installed and configured version of Java™ available on the system where the Tivoli Enterprise Portal client is used.
Supported Java versions for IBM Tivoli Monitoring releases before the V6.3 release included IBM® Java 5, IBM Java 6, Oracle Java 5, and Oracle Java 6. In this case, the upgrade to IBM Tivoli Monitoring V6.3 does not require any corresponding Java upgrade. You can continue to use the existing version of Java that is working successfully with your current release of the Tivoli Enterprise Portal browser and Web Start clients, after upgrading to IBM Tivoli Monitoring V6.3. No other post-installation configuration is required for the Tivoli Enterprise Portal browser or Web Start client.
For a pristine installation of IBM Tivoli Monitoring V6.3 on Windows systems, the upgrade to IBM Java 7 is triggered when you first start the V6.3 Tivoli Enterprise Portal browser client. Windows: Installing IBM Java 7 describes the installation of IBM Java 7.
For a pristine installation of IBM Tivoli Monitoring V6.3 on Linux systems, the installation and configuration of IBM Java 7 is recommended for use with the V6.3 Tivoli Enterprise Portal browser client. Linux: Installing IBM Java 7 describes the installation of IBM Java 7.
