The Update Manager is a tool which is used for installing the service packs (.ppm file) over a product. The service pack may contain certain bug fixes and new feature additions for a particular release version of the product. The service pack can be classified to be either an ordinary without referring to any context of the product (Non - Context based) or it may be context based. This document explains about how to use the Update manager for installation of Software upgrades in AdventNet products. It can be also used by products developed over these products.

Context based patch implies that the patch will have the consolidated upgrades for all the different components of the same product. For example  WebNMS FE & WebNMS Client are different contexts of the product WebNMS. The same patch can be used for updating any context of the product. The Update manager also provides a feature for having Mandatory context and Optional contexts. The Mandatory context can also be called compulsary context and will not be displayed at the time of installation. An Optional context is some additional upgrades, but is not absolutely necessary for the product to function.

The Update Manager also has some useful validation incorporated. This validation includes compatability checks. If a service pack is not compatable ie., service pack of one product is installed in other product , or service pack of one product version installed in other version , then update manager will not allow the user to install these types of service packs.

The UpdateManager also has patch integrity verification to ensure the patch file that is to be applied is not tampered. The contents of the patch file is digitally signed with a trusted certificate and during UpdateManager validation process, the integrity of the patch contents are verified with the help of the digital signature.

To open the Update Manager tool run the "UpdateManager.bat/sh" file present in the <product home>/bin directory. 

The Update manager can be operated in two modes ie., UI and non-UI mode.
