Rocket BlueZone Terminal Emulation

Cost Savings with Rocket Terminal Emulation

Rocket BlueZone — all the functionality, a fraction of the cost

Rocket BlueZone provides a feature-rich browser-based 3270 emulator for IBM host access. BlueZone includes both enhanced TN3270E emulation and basic TN3270 emulation, as well as IBM i (TN5250), UNIX/DEC (VT), and secure File Transfer Protocol (FTP). Our subscription based licensing program can reduce your 3270 emulator acquisition and maintenance costs significantly.

The Rocket Terminal Emulation Web to Host 3270 emulator is first installed on a web server (Apache/Tomcat, BEA, IBM WebSphere Application Server or Microsoft IIS). Once installed, users then download an ActiveX client to their desktop. The download only occurs once and does not reoccur until a new version of Rocket Terminal Emulation Web to Host is installed on the web server. The web server plays no role in the communication to the IBM host—all communication occurs between the 3270 emulator client and the host. User configuration files, macros, etc, can be stored either locally or on the central web server.

Ideal for distributed environments

With Rocket Terminal Emulation Web to Host, remote or distributed Windows users are given all the tools they need for secure, reliable, productive host connectivity. Support of SSL and SSH security, VB Script for macro development, HLLAPI and an Object API for IBM application integration, comprehensive Windows cut and paste, and more are all standard in the Rocket Terminal Emulation 3270 emulator.

Deploy from IBM mainframe or Microsoft IIS Server

Administrators have the option of deploying the the Rocket Terminal Emulation 3270 emulator directly from an IBM mainframe or a Microsoft Windows Server running IIS.  If you want to deploy from the IBM mainframe, you will need to have Apache/Tomcat, BEA WebLogic or IBM Websphere Application Server running to publish the application.

Technical support is available if you need it

If you need help, access to our knowledgeable support team, and all of the resources they bring to the table, is available. Whether you have questions on security, configuration, need help with macro conversion or anything else, we're here to help. Each year, an overwhelming percentage of our customers rate our software and support as top notch. Since most customers take advantage of our low-cost annual subscription licensing, maintaining an excellent level of support is absolutely critical to our ongoing success as a company.

Management loves the cost savings and free migration tools

For customers that need to transition to Windows 8 and replace their existing 3270 emulator, we offer automatic conversion utilities to convert configuration files into the Rocket Terminal Emulation format, making the transition easily manageable. We also provide free macro conversion utilities and services to guarantee an orderly migration. Switching from Attachmate or Micro Focus to Rocket Terminal Emulation is easier than one might imagine at the outset and we have new customers every month confirming this.

With our Rocket Enterprise License Plan (ELP), large organizations see not only a dramatic reduction in 3270 emulator licensing fees, maintenance and future upgrade costs, but they also welcome the freedom we give our clients in terms of ability to distribute Rocket Terminal Emulation anywhere and everywhere. With a Rocket Terminal Emulation ELP, no there is no requirement to track terminal emulation licenses.
