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.

Download the JREUpdate.zip from the following location:

https://software.cisco.com/download/release.html?mdfid=270563413&softwareid=280840592&release=10.5%281%29&relind=AVAILABLE&rellifecycle=&reltype=latest


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

For 12.5(1a) installation, only Redhat OpenJDK JREs have to be used for further upgrades.

If FIPS is enabled in the system, disable FIPS before doing any JRE updates.

Note

After installing the JRE Migration ES on top of 12.5(1) release, only Redhat OpenJDK JREs have to be used for further upgrades.


Note

ES 26 onwards, the JRE in the CVP is updated with OpenLogic JRE. Specific changes, if any, in configuration files of the JRE folder should be backed up and reconfigured after the JRE update.

After installing ES 26, only Openlogic OpenJDK minor version upgrades are allowed.

Procedure

Step 1

Download and install the preferred Java Development Kit (JDK) version on your personal machine.

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:\jdk1.8.0_275\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

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 .
