IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Windows: Upgrading your existing version of Java to IBM Java 7
If you are upgrading to IBM Tivoli Monitoring V6.3 from a previous IBM Tivoli Monitoring release, then as stated previously in this section, no requirement exists to upgrade to IBM Java 7. Your current working Java environment for the Tivoli Enterprise Portal browser and Web Start clients will continue to work after the IBM Tivoli Monitoring upgrade is successfully completed.
If, however, you want to uplift your Java environment to IBM Java 7, you can do this using the following procedure:
- On the machine where the Tivoli Enterprise Portal Server is installed, locate the file named jrelevel.js in the %CANDLE_HOME%\cnb directory. If the jrelevel.js file is found, rename it to jrelevel_bkup.js.
- On the machine where the Tivoli Enterprise Portal Server is installed, locate and open the jreconfig.js file for editing. The jreconfig.js file is located in the <CANDLE_HOME>\cnb directory.
- Change the value of the jreDesiredLevel statement to the following value:
var jreDesiredLevel = "1.7.0";This value references the use of IBM Java 7, and is used by the Tivoli Enterprise Portal browser client to determine which installed level of Java to use.
- Save the changes you made to this file.
- Now launch the Tivoli Enterprise Portal browser client from the machine where you normally run the Tivoli Enterprise Portal client, and follow the procedures outlined in the preceding section: Windows: Installing IBM Java 7.
Results
Although multiple IBM Java releases can be installed and co-exist on the same machine, be aware of the following issues if you want to use multiple releases with the Tivoli Enterprise Portal browser client:
- If you plan on switching from IBM Java 7 back to IBM Java 6 or Java 5 (or vice-versa), make sure you first update the jreconfig.js file located on the Tivoli Enterprise Portal Server machine as described in this section. The value to use for IBM Java 5 is the following:
var jreDesiredLevel = "1.5.0";The value to use for IBM Java 6 is the following:
var jreDesiredLevel = "1.6.0";In addition, the Runtime Parameters found in the Java 5 Control Panel need to be re-entered and saved. See Windows: Java 5 post-installation configuration for information about configuring Java 5 for use with the Tivoli Enterprise Portal browser client.
- You cannot launch two or more independent instances of the Tivoli Enterprise Portal browser client under Internet Explorer, from the same machine, using different IBM Java releases. If you must run more than one instance of the Tivoli Enterprise Portal client that use different IBM Java releases, then you can use another deployment mode for the second (or subsequent) instance. For example, you can run one Tivoli Enterprise Portal instance by using Internet Explorer and IBM Java 5, and a second Tivoli Enterprise Portal instance by using Web Start or desktop deployments running IBM Java 6.
