Chapter 1. Introducing Host On-Demand

The browser-based access of IBM WebSphere Host On-Demand Version 6 (Host

On-Demand) gives you a simple way to reach critical host data, without requiring

you to install any software on your workstation. Host On-Demand uses the power

of Java technology to open the doors to your host system whenever you need it,

wherever you need it, directly from your browser. Just click on a hyperlink to

launch the Host On-Demand Java applet. This Web-to-host connectivity solution

provides secure Web-browser access to host applications and system data through

Java-based emulation, so you can take existing host applications to the Web

without programming.

Support for TN3270E, TN5250E, VT420 and IBM CICS Gateway for Java access

provides a single interface to key host data. Because Host On-Demand is

Java-based, its interface has the same look-and-feel across various types of

operating environments. Host On-Demand also provides a default graphical user

interface (GUI) to simplify the experience for users who are unfamiliar with

traditional ″green screens.″

Using Secure Sockets Layer (SSL) Version 3.0, Host On-Demand extends secure

host data access across intranets, extranets, and the Internet. Mobile workers access

a secure Web site, receive authentication and establish communication with a

secure enterprise host. With client and server certificate support, Host On-Demand

can present a digital certificate (X.509, Version 3) to the Telnet server - such as IBM

Communications Server for Windows NT Version 6 or later, or IBM

Communications Server for OS/390 Version 2.6 or later - for authentication. Host

On-Demand can also integrate the SSL client authentication with IBM Vault

Registry. This allows you to benefit from industry standard public key

infrastructure (PKI) methods. Users request a certificate from IBM SecureWay Vault

Registry, which manages, maintains and ensures certificate validity.

Database On-Demand is included with Host On-Demand to provide access to DB2

information stored on iSeries computers using a Java Database Connectivity (JDBC)

driver. Database On-Demand is a Java applet that allows you to perform

Structured Query Language (SQL) requests to iSeries databases through a JDBC

driver.

Host On-Demand is multilingual and is available in 23 languages, including

double-byte character set languages. Support for the European currency symbol, as

well as keyboard and code-page support for many more languages such as Arabic,

Hebrew and Thai, is also provided. All language versions are available on the

same media, and multiple language versions can be accessed concurrently.

Host On-Demand is shipped on four CDs: one for the OS/400; one for AIX and

other UNIX platforms; one for multiple platforms, including Windows, OS/2, and

Novell; and one for the Host Access Toolkit. It is also available on tape as a zSeries

(TM) program product.
