Description
Resolution:
By default, the 1.4.0 JRE is used for Windows Engines. You can change what version of the JRE is used. For Windows, the JRE used resides on the Manager, and is updated on Engines, so you only need to change the JRE once on the Manager.
It is not necessary to re-install the Engines after adding the new JRE because they will update themselves if Engine Upgrade ( On the Manager Configuration page, in the File Update section) is set to True.
When downloading a new JRE from Sun, download the JRE package, instead of the JDK.
To change the JRE version:
1. In the GridServer Administration Tool, go to the Manager tab, select Manager Configuration, go to File Update, and set Engine Upgrade to True .
2. Open the JRE you wish to use into a temporary directory. It is not recommended that you use a 1.3 JRE. If you need to, please contact DataSynapse technical support. Also, ensure that the JRE you have is the Server version (included in the Java JDK) and not the client version (from the standalone JRE.)
3. 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 local_policy.jar and US_export_policy.jar which should be copied into the jre/lib/security directory.
4. For LiveCluster 3.1.2 and earlier:
Copy the JAR files from the jre/lib/ext directory of the existing 1.4.0 JRE to the new one.
5. Create a ZIP file of the directory containing the JRE files and additional files.
6. Replace the public_html/register/install/jre/jre.ZIP with the ZIP file of the JRE you created. Note: the file is case-sensitive, and ZIP must be uppercase. If you are using an alternate base directory, a read-only installation, or running multiple Managers on one machine, make sure to copy this file into the same location on each DS_BASEDIR directory.
7. Open the file engineUpdate/Win32/jre.dat in your GridServer distribution with a text editor.
8. Replace the 1.4.0 with the version number of the JRE you wish to use.
