Update the Java Runtime Environment (Optional)
The Unified CCE Installer installs the Java Runtime Environment (JRE) to a default location (for example, C:\Program Files (x86)\Java\jre<version>) and creates a JAVA_HOME environment variable set to that location. In most circumstances, you do not need to modify or configure the JRE.
For more information on the JRE version installed, see the Cisco Packaged CCE Software Compatibility Matrix at https://www.cisco.com/c/en/us/support/customer-collaboration/packaged-contact-center-enterprise/products-device-support-tables-list.html.
If you have requirements for a different version of the JRE, you can update the JRE to a later version.
To update the JRE to a later version: Cisco Packaged CCE Software Compatibility Matrix
- Review the Cisco Packaged CCE Software Compatibility Matrix to confirm that Packaged CCE supports the JRE version you want to install.
- Follow the Oracle JRE installer procedure to install the JRE to the VM on which your Unified CCE components are installed.
- Set the JAVA_HOME environment variable to the location of the new JRE.
- Restart the virtual machine.
When you have completed the update to the new JRE version, uninstall the old JRE.
