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 1.8.0_275 to 1.8.0_x.


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 1.8 to 1.9/1.10.


Note

From 12.6(1) ES-12 and higher releases, only OpenLogic OpenJDK is supported.

Procedure

Step 1

Download and unzip the Java Development Kit (JDK) folder on your CVP machine.

Step 2

Copy the JRE folder from the JDK root folder 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:\openlogic-openjdk-8u332-b09-windows-64\jre.

Step 3

Go to the bin folder within the JDK root folder. For example C:\openlogic-openjdk-8u332-b09-windows-64\bin. Copy the jconsole application file and paste it in the path mentioned in Step 2 (C:/JRE).

Step 4

Go to the lib folder within the JDK root folder. For example C:\openlogic-openjdk-8u332-b09-windows-64\lib. Copy the jconsole executable jar file and paste it in the same path mentioned in Step 2 (C:/JRE).

Step 5

Go to C:/Cisco/CVP/bin and 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 6

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 7

Ensure that the script output displays the updated JRE version.

The JREUpdate.bat script takes a backup of the old JRE to C:\Cisco\CVP\jre.old folder location. To revert to the previous backup version of JRE, run this script from the command prompt: C:\Cisco\CVP\bin>JREUpdate.bat revert.
