Updating the Java Runtime Environment (JRE) for Windows Engine
You can update the JRE on DataSynapse GridServer Manager for Windows Engine.
Before You Begin
- Download the new required JDK version.
- Ensure that you use the server version JRE, which is included in the Java JDK, not the client version from the standalone JRE.
To update JRE for Windows Engine, perform the following steps:
Procedure
| 1. | Shut down all running Engine Daemons. |
| 2. | Create a temporary directory, for example, C:\temp. |
| 3. | Copy the new server JRE from the JDK into the temporary directory. |
| 4. | Rename the JRE folder with jre.platform format. For example, jre.win-amd64. |
| 5. | Create a .zip archive of the directory that contains the jre.win-amd64 folder. For example, jre.win-amd64.zip. |
| 6. | Navigate to $DS_INSTALL\manager\webapps\livecluster\public_html\register\install\jre\. |
| 7. | Delete the existing .zip file that you want to replace. |
| 8. | Copy the new .zip file to $DS_INSTALL\manager\webapps\livecluster\public_html\register\install\jre\. |
| 9. | Set the appropriate permissions on the new .zip file. |
| 10. | Edit the jre.platform.dat file. For example, jre.win64.dat. |
| 11. | Replace the old JRE version number with the new JRE version number. |
| 12. | Start the engines. |
