IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Linux: 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.
You can also complete the following steps if you want to upgrade your Java environment to IBM Java 7 for the browser client:
- On the machine where the Tivoli Enterprise Portal Server is installed, locate the file named jrelevel.js in the following directory:
- <CANDLE_HOME>\cnb
- <CANDLE_HOME>/cw
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 following directory:
- <CANDLE_HOME>\cnb
- <CANDLE_HOME>/cw
- 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.
- Start 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 sections: Linux: 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 both of these 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 6 is the following:
var jreDesiredLevel = "1.6.0";
- When switching between IBM Java releases, re-enter and save and Runtime Parameters you many have entered previoulsy for the appropriate JRE.
- The version of the Java plug-in used by Firefox is based on the registration of the plug-in object. Follow steps 6 and 7 in Linux: Installing IBM Java 7 to establish a symbolic link to the plug-in object, depending on what version of Java you are switching over to use (Java 5 or Java 6). For Java 5, the plug-in object is named libjavaplugin_oji.so. For Java 7, the plug-in object is named libnpjp2.so.
