TDP ObjectivesTDP Objectives

Develop strategic plans for a common set of TPF development tools that conform with EDS & IBM direction and industry trends

– Follow EDS Direction

– Remain Close to IBM’s Direction

– Eliminate VM as a TPF development platform

– Eliminate OS/390 as a TPF development platform

– Attain and provide a state of the art development platform for TPF

EDS Confidential 3

Why Develop TDP?Why Develop TDP?

• Market Forces – Move to Standards Based Applications Development

• IBM expanding use of Posix standards in TPF– Expanding use of Open Source

• IBM porting Open Source to TPF (Apache, Mail Server)

• IBM moving TPF support from OS390 to Linux with NBR

• Client requirements– Elimination of VM development Platform

– “TPF development is a integrated environment that leverages industry-standard technologies and supports a full range of TPF construction, testing, and implementation functions”

Why Develop TDP? (Cont.)Why Develop TDP? (Cont.)

• Problems with existing platforms (VM)– Loss of support– Inadequate support for ported products

• Lack of synergy – Provide common TPF development platform to facilitate

staff leverage– Develop cross platform leverage based on WS and Posix

experience.• Newer development models offer more

productivity.

TDP Schedule DriversTDP Schedule Drivers

• Poor support for source repositories

• C/C++ Support

• Support for ported Unix software

• Open Source Support - NBR

EDS Confidential 6

Guiding PrinciplesGuiding Principles

• We will follow EDS’ & IBM’s tool strategies.

• Must support distributed development.

• We will not develop any interim tool or technology which will make the implementation of the IBM recommended tool suite more difficult.

• Development tools will be chosen or built using technologies which leverage the skills of a TPF programmer.

• Development will be UNIX System Services centric and will be migrated to Linux in the future.

• Development will lean to thin client designs.

• Web Browser, VATPF and later WebSphere will be the primary GUI interface to the tool suite.

• TPF C/C++ development will only be supported through VATPF

What is CVS?What is CVS?

• Concurrent Version System (CVS)

• GNU Public License

• Unix Based repository

• Does not include a Change Management System

• Maintains Control Information

– Facilitates Source Associations (Packages & Projects)

– Change History

• Provides Unix based Security

– Support for Groups

– USS Interface to RACF or ACF2

• No internal TPF versions support – Internal versioning

• Data Maintained as Deltas – as revisions which are cross referenced with TPF versions.

EDS Confidential 9

• Follows IBM Direction

• Portable to Linux

• Strong Value Proposition– Low Acquisition and Maintenance cost

– Reduced DASD Requirements

– Leverage Industry Support Community

– No increase cost for TPF Support vs. other Options (Must develop TPF version and Changes Management for all options)

• Widely Used

• Flexible Data Structures

Phase 2 CVS ToolsPhase 2 CVS Tools

• Source Synchronization – copies new production source to CVS

• Versioning tool – Maps CVS release tags to TPF versions

• CVS Interface tool – Web interface

– CVS Scan

– Base CVS functions – check out, check in, etc

– Source and listing viewer

– Infrastructure support
