Java Runtime Environment Minor Update

Java Runtime Environment Minor Update

Use the JREUpdate.bat script to install a minor update of Java Runtime Environment (JRE) version on your Unified CVP Server. For example, you can install a minor update of JRE version 17.0.13 to 17.0.14.

Download the JREUpdate.zip from the following location: https://software.cisco.com/download/home/270563413/type


Note

The script does not support a major upgrade of JRE versions. For example, the script does not allow a major upgrade of JRE Version 17.0.13 to 19.


Note

For Unified CVP 15.0(1) and higher releases, only Redhat OpenJDK JREs have to be used for further upgrades.

Procedure

Step 1

Download and install the preferred Java Development Kit (JDK) version on your personal machine at https://www.openlogic.com/openjdk-downloads?field_java_parent_version_target_id=416&field_operating_system_target_id=436&field_architecture_target_id=All&field_java_package_target_id=All

Step 2

Copy the JRE folder from the installed JDK to a known location on the Unified CVP Server. For example, C:\JRE.

Note

 

The jre folder is available in the JDK root folder. For example: C:\jdk17.0.13\jre.

Step 3

Right-click the JREUpdate.zip file and extract the files to a known location on your Unified CVP Server. For example, C:\Cisco\CVP\bin.

Step 4

Run this script from the command prompt: C:\Cisco\CVP\bin >JREUpdate.bat apply C:\JRE.

The script runs and Unified CVP JRE is updated to the new version.

Step 5

Reboot the Unified CVP server.

Step 6

Ensure that the script output displays the updated JRE version.
