Resolution:
By default, the 1.4.0 JRE is used for Unix Engines. You can change what version of the JRE is used. For Unix, there is not an update mechanism similar to the Windows, so you need to update the JRE on each Engine.

When downloading a new JRE from Sun, download the JRE package, instead of the JDK.

To change the JRE version:

   1. Shut down any running daemons:

      engine.sh stop

   2. Change directories to the Engine home directory on the machine running the Engine, for example, DSEngine.
   3. Move the current JRE to a new directory:

      mv jre jre1_4_0

   4. Unarchive the desired JRE into a new directory, such as jre1_4_1_04.
   5. Download the Java Cryptography Extension (JCE) from Sun at http://java.sun.com/j2se/1.4.2/download.html (at the bottom, under "Other Downloads"). This download contains the two files localsecurity.jar and US_export_security.jar which should be copied into the jre/lib/security directory.
   6. For LiveCluster 3.1.2 and earlier:
      In addition, you will need to copy the jar files from the jre/lib/ext directory of the 1.4.0 JRE to the new one.
   7. Symlink the desired JRE to jre:

      ln -s jre1_4_1_04 jre

It is not recommended that you use a 1.3 JRE. If you need to, please contact DataSynapse technical support.
