What is Host On-Demand?

IBM Host On-Demand provides cost effective and secure browser-based and non-browser-based host access to users in intranet-based and extranet-based environments. Host On-Demand is installed on a Web server, simplifying administrative management and deployment, and the Host On-Demand applet or application is downloaded to the client browser or workstation, providing user connectivity to critical host applications and data.

Host On-Demand supports emulation for common terminal types, communications protocols, communications gateways, and printers, including the following:

• TN3270 and TN3270E terminals
• TN5250 terminals
• VT52, VT100, VT220, VT320, and VT420 terminals
• The Secure Shell (SSH)
• Transport Layer Security (TLS)
• File Transfer Protocol (FTP)
• Customer Information and Control System (CICS) Transaction Gateway
• TN3270E and TN5250 printers

You can use the Java component-based Host Access Toolkit to create customized e-business applications. This Toolkit contains a rich set of Java libraries and application programming interfaces: Host Access Class Library (HACL), Host Access Beans for Java, and Java Enterprise Edition (J2EE) connectors. Host On-Demand also includes Database On-Demand, which provides an interface for sending Structured Query Language (SQL) queries to IBM DB2 databases hosted on IBM System i7 systems.
