IBM Tivoli Monitoring, Version 6.3

Browser plug-in support for Java applets

In Tivoli® Monitoring V6.3, all Java-based Tivoli Monitoring infrastructure components are being upgraded to the Java™ 7 runtime environment. You might have to complete additional tasks to upgrade the Tivoli Enterprise Portal component if you use the Tivoli Enterprise Portal browser or Web Start clients.

If you are doing a pristine installation of IBM® Tivoli Monitoring V6.3, see Table 1.

Table 1. Tivoli Enterprise Portal client support
Java runtime environment (JRE)	Windows platforms¹		Intel Linux platforms¹
	Internet Explorer V8 - V9	Firefox Extended Support Release	Firefox Extended Support Release
JRE 1.6, 1.7	Windows: Installing IBM Java 7	Windows: Installing IBM Java 7	Linux: Installing IBM Java 7
JRE 1.5	JRE 1.5 no longer supported ²	JRE 1.5 no longer supported ²	JRE 1.5 no longer supported ²
Note: Both 32-bit and 64-bit browser versions are supported. Firefox Extended Support Release or higher requires Java 1.6 or higher. If you specify Java 1.5 in `jrelevel` or `jreDesiredLevel` and 1.5 is not already installed, you will be prompted to install Java 1.7 irrespective of what is specified in `jrelevel` or `jreDesiredLevel`. For Internet Explorer, the level of IBM JRE installed depends on the values specified in `jrelevel` or `jreDesiredLevel`.

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 6.3 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.

Note: Starting with the IBM Tivoli Monitoring V6.3 release, use of Java 5 (1.5) is not recommended for use with the Tivoli Enterprise Portal browser client. It is strongly recommended that you upgrade to using Java 7 (1.7) that is provided with IBM Tivoli Monitoring V6.3. The use of Oracle's Java 7 is also supported for V6.3.

However, if you decide after upgrading to IBM Tivoli Monitoring V6.3 that you want to upgrade your installed version of Java to IBM Java 7, you can do so by using much of the same procedure used for a pristine installation of IBM Tivoli Monitoring V6.3. See the following sections for information about manually upgrading your existing version of Java to IBM Java 7:
