A Host On-Demand Macro (HOD) is an XML script that allows a Host On-Demand client to interact automatically with a host application running on a terminal emulator session. For example: 3270 Display session, 5250 Display session, VT Display session or CICS Gateway session, and so on.
Client Authentication is a process that helps users to securely access a remote host/server by exchanging a digital certificate. TLS (Transport Layer Security) Client Authentication (also referred to as Mutual Authentication or Mutual SSL) is one of the most commonly used Client Authentication mechanisms.
Host Access Toolkit is a comprehensive set of application programming interfaces (APIs) for programmers to develop custom applications that run with HOD.
Emulator High-level Language Application Program Interface (EHLLAPI) standard and API was introduced by IBM for IBM 3270 & 5250 servers, allowing client applications to access information on the host screen. IBM EHLLAPI standard is supported by most of the Terminal Emulator solutions, and forms the basis for many enterprise automation suites and application customization.
IBM Host On-Demand comes with a setup of Administration Utilities that are used for various purposes.
Host On-Demand provides graphical user interface for Certificate Management on Windows, Linux and AIX (command line).
Host On-Demand migration utility can be used for migrating HOD server files from a lower version to a higher version.
Currently Host On-Demand migration is a manual process. Administration has to do the following steps in order to migrate:
What is SSO?
SSO refers to a mechanism where a single authentication provides access to multiple applications. An authentication token that is generated once is stored and seamlessly passed to configured applications.
This reduces time spent in entering passwords for the same identity, and increases security since the credentials are passed to an SSO server and not to the actual service.
The below diagram explains a typical SSO implementation
Introduction to the Host Access Class Library for Java
The Host Access Class Library (HACL) for Java provides a core set of classes and methods that allow the development of platform independent applications that can access host information at the data stream level.
What is Programmable Host On-Demand
The Programmable Host On-Demand API is a set of Java APIs that allow developers to integrate various pieces of the Host On-Demand client code, such as terminals, menus, and toolbars, into their own custom Java applications and applets.
