IBM—CUSTOMER FACING

Program Manager, CICS/TS 4.1 Early Test Program Activities for CICS/TS 4.1 were similar to my activities for CICS/TS v3.2 (outlined below). Continued to grow program participation by seeking out and enrolling Education Providers and

Application Vendors with CICS-based products Created a Control Block “registry” for CICS which allows interested parties to request notification of

when specific CICS control blocks of interest are modified by the CICS Development Team Established a CICS “sandbox” z/OS system for education vendors who do not otherwise have

access to a running CICS system to build and execute sample applications for the purpose of creating education materials.

Expanded the program from 18 participating ISVs to over 40 participants.

Program Manager, CICS/TS 3.2 Early Test Program The development of CICS/TS 3.2 was well over 18 months using an “iterative” development

approach. Early code was provided in code drops approximately every four months. Responsible for planning, preparing, and presenting the technical education for changes introduced

with each code drop Developing the education required close coordination with the CICS development team Education was presented to CICS Beta Customers, internal IBM product development labs, and

ISVs targeting their respective products for “same day support” of the new release of CICS

Technical Lead— UNIX to z/OS Migration Technical Lead for an on-site IBM team to deliver a Proof-of-Concept for a major U.S. insurance

company Ported over 600,000 lines of Encina/DCE-based C++ code to CICS/TS running on z/OS Nineteen C++ libraries (DLLs) were ported to CICS/TS on z/OS with minimal changes to the source

o This had never been done anywhere before Coordinated the efforts of two mainframe programmers and two UNIX programmers Acted as “translator” of concepts between programmers in the two computing environments

Customer Workshops Facilitator, CICS/WAS Integration Co-lead customer education and hands-on workshops for integrating legacy CICS applications with

WebSphere Application Server (WAS) These were typically pre-sales engagements at the customer location to provide in-depth information

on IBM’s strategy for integrating legacy applications with WAS Exposed existing customer programs as WebServices in real time as part of the workshop

Customer Workshop Facilitator Lead customer education workshops on CIIS at varying degrees of technical depth Workshops were presented either at the customer location or at an IBM facility Included customers from around the world, occasionally requiring presentation through an

interpreter Often the customer audience was a mixture of executive management and senior technicians Workshops resulted in multi-million dollar sales and several customer references for IBM

DIRECT HIRE ROLES

Extensions to the EXEC CICS API Developed an infrastructure of CICS Global User Exits, Task-Related User Exits, and subroutines to

provide extensions to the CICS Application Programming Interface Developed a translator similar to the CICS Command Level translator (for both COBOL and

Assembly Language Programs) to translate “EXEC DTC” commands to a standard call interface Commands both enhanced and extended the IBM-supplied commands and/or provided functions not


available in native CICS

CICS Shared Data Tables Implementation Designed and developed the CICS user exits required to implement the Shared Data Tables feature

in CICS Obtained significant response and CPU time improvements for critical business applications--with no

application program changes Presented experiences at SHARE

CICS Dynamic Transaction Routing Implementation Researched, designed, and developed the Dynamic Routing environment for a multiple TOR/AOR

configuration Developed my own Dynamic Routing Program Identified several unique classes of Dynamic Transactions and gave them names such as

“Kamikaze” and “Migrant Worker” to reflect their routing requirements The design has proven to be easily extended to further meet business requirements Presented experiences at SHARE

MQ Systems Administrator Short-term contract to upgrade existing MQ v6 to MQ v7.1 implementation running under z/OS In an unrelated contract, I was responsible for 10 Windows-based MQ instances communicating

with two MQ subsystems running under z/OS

EXTRACURRICULAR ACTIVITIES

CICS Architecture Forum Representative The CICS Architecture Forum (CAF) is a global group of customers, consultants, and ISVs who work

with IBM CICS strategists and planners to provide architectural solutions and direction to the CICS family of products. It is the longest running customer council in the history of CICS and is greatly respected by both the CICS and MQ development organizations

I was one of five customers worldwide invited to the inaugural meeting in Hursley in 1994 Co-authored technical papers on topics such as

o Cross-Platform Migrationso Advanced Transaction Modelso Multiple COMMAREAs (which became the design for Channels and Containers), o Structured Messaging (which became the design for WMQ Message Broker’s MRM)o “N-pass” compliers for translators such as CICS and DB2 “EXEC” interfaces. That idea was

rejected, but it lead to the integrated CICS translator for the COBOL compiler
