If transport exists between the user s workstation and the WinFrame server, you can create an icon on the user s desktop to take the actions listed at the top of the following page. • Automatically launch the ICA client • Connect to the specific WinFrame server (or group of servers if using load balancing) • Automatically log on the user • Automatically launch the program In Conclusion One of the main benefits for IS administrators or decision makers that was described in this chapter is the great extent to which your department can leverage its knowledge of Windows NT.

The ICA protocol provides true location independence for Windows-based appli-cations. It also allows Windows-based applications to run at one location and display the program s user interface somewhere else. ICA comprises a universal thin client, a protocol, a platform, and system services. Designed to provide high-performance display of Windows-based applications over local area networks (LANs), wide area networks (WANs), or dial-up devices while minimizing network traffic, the ICA protocol in conjunction with ICA services and the ICA client can deliver complete Windows-based applications even over low-bandwidth connections.

Currently, the users dial up the server using RAS accounts and log on to the network. exe from an icon on their laptops, which accesses an Oracle database on an HP5000. Over RAS, the performance is slow. In this situation, you can introduce a thin-client/server solution with Win-Frame to speed things up. Once WinFrame is in use, the users do exactly the same things they did over RAS, but instead of the application executing on their laptops, it executes on the Win-Frame server. A user can execute a thin-client session from an icon on the desktop.
