Web Enabling Your HP 3000

Level 8’s Geneva Message Queuing

Geneva Message Queuing for HP e3000 provides communication and interoperability between

HP e3000 - MPE/iX Version 5.1 and Windows NT.

Message Queuing

Message queuing is a very simple, reliable mechanism for sending information between applica-

tions that reside on different business systems.

Prior to message queuing, cross-platform applications were built using one-off, point solutions

that needed to be created each time a new development effort was started. With message

queuing, the overhead needed to build distributed, cross platform applications has been greatly

reduced. As a result, building cross-platform distributed applications is now relatively simple.

Web Enablement

A major stumbling block in Web Enablement is connecting business systems in a simple and

reliable way. Geneva Message Queuing (GMQ) is ideally suited for connecting applications runs

on HP e3000 with web servers to provide guaranteed, “exactly-once” delivery of messages.

GMQ supports complicated, multi-step, business transactions. A typical transaction may

include HP e3000 servers, web servers, application servers or database servers, outside service

bureaus for checking credit cards, inventory systems, and supply chain partners. GMQ is a con-

sistent, reliable transport mechanism for all of these different servers.

GMQ also allows HP e3000 applications to be decoupled from the web server so that the appli-

cation sending a message can continue processing without having to wait for a reply from the

application receiving the message. If the receiver is temporarily unavailable, the message will be

forwarded at a later time.

Another use for GMQ in web enablement is de-coupling the interactive web experience from the

HP e3000 business process. Since GMQ supports asynchronous communication it is easy to

respond to the user and initiate HP e3000 processing in a way isolate the web users from the

back-end environment.

In summary message queuing technology is crucial to Web enabling HP e3000 systems and iso-

lating the front-end Web experience from HP e3000 business processes. For more information
