CVP & VVB Java, Tomcat and Informix Default Versions and Upgrade Procedures

Introduction

This document describes supported versions of Java, Tomcat and Informix for CVP and VVB, also provides references to proper upgrade procedures. 

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

• Customer Voice Portal (CVP)
• Virtualized Voice Browser (VVB)

Components Used

The information in this document is based on these software versions:

• CVP 11.5(1), 11.6(1), 12.0(1), 12.5(1), 12.6(1), 12.6(2)
• VVB 11.6(1), 12.0(1), 12.5(1), 12.5(1) SU, 12.6(1), 12.6(2)

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

CVP

CVP Processes and Their Purposes

• Java

  CVP Applications, primarily Call Server, Voice Extensible Markup Language (VXML) Server, WebServices Manager or OPSConsole Server, are java based applications and they need Java runtime Environment (JRE) for execution.

  Any functionality breakage of JRE can impact the Call Service, Standalone VXML Server Service or Operations Console Service.

  Misconfiguration of java can cause security related issues even though the services are up and running.
  
  

• Tomcat

  These instances of Tomcat run on CVP server and depend upon the type of deployment:

- Cisco CVP CallServer hosted by C:\Cisco\CVP\CallServer\Tomcat on CallServer.

- Cisco CVP VXMLServer hosted by C:\Cisco\CVP\VXMLServer\Tomcat on VXML Server.

- Cisco CVP CallServer hosted by C:\Cisco\CVP\CallServer\Tomcat on Reporting Server.

- Cisco CVP WebservicesManager hosted by C:\Cisco\CVP\wsm\Server\Tomcat on all CVP Servers.

- Cisco CVP OPSConsoleServer hosted by C:\Cisco\CVP\OPSConsoleServer\Tomcat on Operations Console Server.

• Informix Dynamic Server

  It is the Database used by CVP Reporting Server to store all Reporting Data (that is VXML and Call Data). 

CVP Default Versions

Upgrade Guidelines

Java

Caution: Major upgrades (i.e 1.8 -> 1.9) are not supported.

Minor upgrades ( i.e 1.8.172 -> 1.8.192) are supported and the procedure can be found here.

Note: You must take adequate responsibility of doing proper tests before upgrading Java minor versions. Read the Java Release notes to determine if any dependent component for CVP is obsoleted in new java version. Example: If any cipher or algorithm used for security is obsoleted.

Caution: After the JRE update, copy these 3 files from C:\Cisco\CVP\jre\bin\client to C:\Cisco\CVP\jre\bin\server folder:
classes.jsa
jvm.dll
xusage.txt
The client folder shows after doing the JRE update and you need to move these 3 files to server folder so the VXML Service service can start.

Tomcat

Caution: Major upgrades (i.e 8.0 -> 8.5 or 9.0) are not supported.

Minor upgrades ( i.e 8.0.24 -> 8.0.33 ) are supported and the procedure can be found here.

Informix Dynamic Server

Caution: Major and Minor Upgrade of Informix is currently not supported.

If you are experiencing Informix vulnerabilities contact Cisco TAC.

VVB

Processes and Their Purposes

• Java: Virtualized Voice Browser (VVB) Engine runs on JRE.
  
  
• Tomcat: Hosts the webservice which is required for VVB to run.
  
  
• Informix: Used for internal DB.

VVB Default Versions

Upgrade Guidelines

VVB does not support any manual way or through ES/ET java/ tomcat/ informix upgrade. It can only be accommodated through the release cycle.
