Introduction

ClearView is a web centric solution for access to Unisys Clearpath systems from Quickware terminal emulation products.  It runs on a Windows IIS server using the .NET framework.

ClearView is the management web and ClearConnect is the "user" web.  The ClearConnect web is used directly by Web-UTS users but indirectly by QTerm users.  This means that, for example, a Web-UTS user would navigate a browser to the ClearConnect web, login, and be sent the appropriate web page containing the ActiveX control.  A QTerm user would be unaware that QTerm itself makes a connection to the ClearConnect web in order to retrieve its profile information.

Your users can access your hosts using any of these technologies:

  • QTerm desktop emulator
  • Web ActiveX control in a web browser
  • Java applet in a web browser
  • Customized browser solutions

In all cases the software is downloaded from the web server, as required, and made available on the user desktop.  Equally important is that all the specific user configuration details are retrieved as a profile from the web server when the client software starts up.  This means that these details can be easily and conveniently changed by a  supervisor at any time.

Note that the web server is only used for serving up the software and profiles and gathering statistics.  All traffic from the client emulator flows directly to the host over a tcp/ip connection without passing through the web server.

At the heart of the system is a database of resources that are managed on a web server which hosts 2 distinct webs; ClearView and ClearConnect.

  • ClearView provides the facilities to set up and manage the database.  As such, it is highly recommended that anonymous access is not allowed for this web.
  • ClearConnect is the web to which your users connect.  This web is implemented to support a user/password logon mechanism.
    A department is a group of users with similar attributes, mainly defined by using the same profile.

   A user represents a real person and is a member of a single department.

   A terminal represents a single screen of a terminal emulator, whether it be desktop or browser based.

   A profile defines how a user works within the system, specifying which emulator mode to use and what software level is required etc.  A profile for a department governs the behavior of all users in that department.

   A host group is simply a grouping of hosts, specified in a profile to limit the hosts that can be accessed by a given set of users.

   A host defines the address, tcp port number and various other attributes of a host computer.
