DualShield server is a JAVA application. It runs on a framework that consists of 3 components, namely Tomcat, Java Runtime Environment (JRE) and MySQL database engine. From time to time, those framework components might need to be upgraded.
DualShield install its own copy of Tomcat, JRE and MySQL. It does not use or share other instances of Tomcat, JRE or MySQL that might have been also installed on the same machine by other applications. Therefore, upgrading other instances of Tomcat, Java or MySQL has no effect on DualShield. To upgrade the framework components used by DualShield you must use the framework upgrade tool supplied by Deepnet Security in the DualShield platform. You should not attempt to upgrade the framework components in the DualShield platform using other third party tools.
