DSView software client session
The DSView software client session is a single HTML session between the client web browser
and the server. For each DSView software client session, the user must log into the DSView
software server. Multiple DSView software client sessions can exist between a given DSView
software client PC and the DSView software server. This occurs when the user launches
another web browser window and connects to the same DSView software server.
A DSView software client session may contain multiple target device sessions.
DSView software hub server
A DSView software hub server is responsible for maintaining the master copy of the DSView
software system database. Only one server in a DSView software system can be configured as
the hub server. Spoke servers in a DSView software system perform database replication with
the hub server. The DSView software hub server acts as the traffic cop for database replication
between itself and all of the other servers in a DSView software system.
The DSView software hub server and a spoke server offer the same software functionality to a
user. The distinction of hub or spoke only has to do with the database replication role the
server plays and not with the software functionality the server offers to the user.
The DSView management software versions of the spoke server and hub server must match in
order to register the spoke server. For example, you may not register a spoke server running
DSView management software version 3.0 with a DSView software hub server running
DSView management software version 3.1.
DSView software spoke server
A DSView software spoke server is responsible for initiating database replication with the hub
server. A spoke server sends its database changes to the hub server and receives database
changes from it.
The DSView software hub server and a spoke server offer the same software functionality to a
user. The distinction of hub or spoke only has to do with the database replication role the
server plays and not with the software functionality the server offers to the user.
The DSView management software versions of the spoke server and hub server must match in
order to register the spoke server. For example, you may not register a spoke server running
DSView management software version 3.0 with a DSView software hub server running
DSView management software version 3.1.
DSView software server
A DSView software server is a customer provided PC on which the DSView management
software is installed.
DSView software system
A DSView software system includes all the components required to provide DSView software
functionality, including the DSView software server, DSView software client, managed
appliances and target devices.
