IBM after acquiring Rational Software in 2003 and with Host On-Demand Version 11 changed the branding of Host On-Demand as a component of the IBM Rational Host Access Platform. The connections are generally applied in a secure Internet environment using TLS, or SSL through the employment of Java's Virtual Machine. IBM Websphere Host On-Demand provides access to IBM i (5250), IBM System z (3270), and DEC/UNIX systems through host screen emulation within the web browser. The second generation product was known as IBM Host On-Demand Version 1 through version 10. IBM Corporation in concert with Netscape Communications Corporation ultimately leveraged the popularity of the web-based host access for use with OS/2 and subsequent dissimilar computing operating systems. The Netscape versions offered limited functionality and essentially allowed web-based users to access the 3270 and UNIX, VAX and other computer host systems via the Netscape Navigator and Netscape Communicator web browser. Standard telnet clients cannot be used as a substitute for TN3270 clients, as they use fundamentally different techniques for exchanging data. TN3270 allows a 3270 terminal emulator to communicate over a TCP/IP network instead of an SNA network. Telnet 3270, or TN3270 describes either the process of sending and receiving 3270 data streams using the Telnet protocol or the software that emulates a 3270 class terminal that communicates using that process. Inventu has helped many organizations, both large and small, convert from being trapped by their Java TN5250 terminal emulators - Learn more about What You Should Look For in a TN5250 Web Terminal Emulator.Delivery of the first web-based Telnet 3270, or TN3270 emulation adaptation is credited to Netscape Navigator a web browser designed by Netscape Communications Corporation. Other vendors may offer "HTML5 Web Terminal Emulators" but the server and network impact of these are radically different NOT Inventu Viewer+, with our robust and mature compressed datastream technology. Inventu Viewer+ is The Only Web Solution Powerful and Efficient Enough to Replace your Existing TN5250 Desktop or Java/ActiveX Terminal Emulator What once was a slick solution is now a big PAIN and your users are the ones suffering a loss of productivity and compatibility-only Internet Explorer 11 still works with Java applets! Originally, Java provided a slick way to reduce the hassles of installing desktop terminal emulators while also enabling integration with in-house Web Applications through a variety of HLLAPI-derived API's.īut Oracle has withdrawn support for Java applets, making their use problematic both from a management and security perspective. IBM/Rational Host-on-Demand and Microfocus/Attachmate Reflections for the Web are two of the most popular Java-based Web terminal emulators in-use today. With Inventu Viewer+, the TN5250 applications can be integrated at the browser so that the users see a single menu, and can easily switch between other web applications and the TN5250 emulation session.Īre You Struggling Managing Obsolete Java/ActiveX TN5250 Emulators? Many companies have implemented user productivity applications that work as Web applications, yet still have a terminal emulator running on the user's desktop. With the Inventu Viewer+ FVTerm application integrated with your chosen web application identity framework and running with the Industry standard SSL solution of Microsoft IIS, TN5250 applications can be delivered as 100% HTML and javascript to all popular browsers, with no changes required on the AS400 / iSeries / IBM i. Meanwhile, the use of TN5250 outside of a company's walls is a frequently a very low-security environment. TN5250 is now the most popular method of delivering AS400 and iServer 5250 terminal emulation due to the flexibility and freedom from proprietary SNA and Twinax network environments.
