Enhancing the HP e3000 User Interface

OSCAR C/S Workbench for MPE
OSCAR’s development, productivity and run-time management tools allow you to harvest,
revitalize and indefinitely extend the useful life of legacy HP e3000 applications in:
• New client/server development,
• E-Commerce via the Web, and
• Peer-2-Peer integration of applications—turnkey, ERPs, legacy—on one or a combination of
mid-range server platforms (e.g. MPE, UNIX, NT, AS/400)
With the OSCAR Client/Server Workbench for MPE, companies can convert their MPE legacy
systems into Client/Server solutions, choosing from an unprecedented number of development
tools to engineer new User Interfaces—thus better future-proofing MPE applications from
inevitable technological change in the User Interface technology market. OSCAR’s conversion of
MPE applications into Client/Server applications results in the deployment of a new Business &
Data Server on the HP e3000. The existing application can run side by side with the new
Business Server, providing an easy migration path. Single functions at a time can be converted,
allowing developers to incrementally migrate an application to the new C/S architecture.
The Process
The developer uses OSCAR for each step in the conversion process (see Figure 1).
• Existing MPE data and logic are analyzed and transformed into subroutines.
• Using the subroutine interface, OSCAR publishes the routines as shared networked services.
• In parallel, User Interface developers subscribe, to these shared services. OSCAR will provide
the User Interface developer with the necessary code enabling the developer to use (invoke)
the services from within their User Interface environment.
• As an ongoing operation, developers will find that, OSCAR has cataloged these services,
acting as an organized central librarian of all your company’s reusable software components.
