Situation

This technical note briefly discusses the considerations for accessing your host(s) from a mobile device and the Attachmate products that offer this capability.

Resolution

You can connect to your host(s) from mobile devices by using web-based HTML emulation, native iOS or Android apps, Windows-based applications, or web-based Java emulation.

When choosing a host access solution, consider the device's screen size, aspect ratio, and whether HTML 5, Java, or Windows is supported. Also consider the types of terminal emulation supported by Attachmate products.

HTML Web-based Terminal Emulation

Host Access for the Cloud and Verastream Host Integrator provide "zero footprint" solutions since no Java or client software needs to be installed on the mobile device. These products provide wide compatibility with HTML5-capable web browsers on smart phones, tablets, and mobile devices including iPhone, iPad, Android, Windows Phone, and BlackBerry.

The terminal pages feature:

  • Modern look and feel.
  • Responsive display using the full browser width, or resize the window as desired.
  • Easy entry of host function keys in terminal pages with a transparent on-screen keyboard. To use the keyboard, tap or click the "Fn" graphic in the upper right.

Host Access for the Cloud (formerly Reflection ZFE)

Host Access for the Cloud provides terminal emulation for 3270, 5250 and VT host terminal types with centralized control.

Beginning in version 1.1 (October 2015), mobile touch support, macro functionality, and on-screen function key support (Quick Keys) is provided for mobile devices without full keyboards. You can also map colors and host keys for a more user-friendly experience. For more information about Host Access for the Cloud, see https://support.microfocus.com/product/?prod=RZFE.

Verastream Host Integrator

In Verastream Host Integrator (VHI) version 7.5 or higher, you can quickly and conveniently connect to your IBM hosts in a web browser—without configuring a model in Design Tool or generating a Web Builder project. To access the Terminal3270 or Terminal5250 web applications, do one of the following:

  • On Windows, "3270 Terminal Session" and "5250 Terminal Session" shortcuts are installed in Start > All Programs > Attachmate Verastream > Host Integrator.
  • From any system, you can open the URL http://vhiservername:8081/Terminal3270/ or http://vhiservername:8081/Terminal5250/.

Furthermore, to improve usability of your host application on mobile devices, you can model it and generate an "HTML5 Web Application" project in Web Builder. This enables displaying of form pages with drop-down procedure selection.
