Principal Technical Staff Member - Team Leader

for ICV (Integrated

Customer View) Transaction Server and ACFBI Data Server

3/95

- Present

- Responsible for all technical aspect of the application. ICV is a

client/server application. It utilizes both MVS and UNIX resources.

Transaction Server and ACFBI server both are on UNIX. Transaction

Server houses the customer/product cross-reference information. The

customer data is stored in the ORACLE Parallel System with about 400

GB in size. ACFBI Server houses all bundled billing

arrangement/invoice/statement information. Transaction Server

interfaces with many other client applications via TUXEDO and MQ.

TUXEDO is used to interface with the UNIX client applications. MQ is

used to interface with the MVS client applications. TUXEDO is also the

transaction manager, which directs the user request messages within

Transaction Server and ACFBI server. The technical challenges of this

application are supporting a large database, high transaction volume,

and stringent response time. The average online transaction volume is

more than three millions per day. The average transaction response

time is under 750 milliseconds. The challenge in the human resource

area is finding the qualified people to work on the various

technologies utilized by the application. My functions are to design

and architect a highly flexible and efficient system. The system must

be able to provide a near 7x24 availability, easy to maintain, having

the excellent quality. The deliverables must be on- time, on-target,

and on-budget. My functions also include interfacing with a diverse

groups, such as the business requirement, data base administration,

system test, production support, capacity planning, etc. To be the

team leader I am responsible for hiring and managing about 20

technical people to implement the application. Since I have strong

technical background I also develop performance tools to measure the

message response time and overall system performance, to analyze the

performance reports, to identify the problem areas, and to resolve the

problems.

for CSD Application

8/94

- 3/95

- Provided the architecture direction for the re-engineering effort of

the system. The application was mainly a MVS system using DB2 as the

DBMS and CICS as the TP monitor. The re-engineering effort was to

convert the system to be a GUI front end and a UNIX/ORACLE back end

application. My functions were to determine the system software

required supporting the effort. Many vendor software such as

PowerBuilder, screen painters were evaluated. A prototype system was

developed to evaluate the two transaction managers TUXEDO and TOP END.

The evaluation report was presented to CCS SOE committee and AT&T

foundation architecture committee and made TOP END a standard

transaction manager for UNIX in AT&T foundation architecture.

Senior Specialist - DBA/Performance Specialist

for CPP Application

8/91

- 8/94

- Provided DBA and technical support to a large DB2 system, CPP (ATT

Calling Card Provisioning Process). CPP was one of the largest DB2

applications in the world. CPP processes about 1 million online

transactions and various batch feeds each day. The DB2 data resided on

150 3390-mod3 packs. The largest DB2 table contained more than 200

million rows. My functions included logical and physical design of DB2

tables for supporting the new releases of the application; technical

support to the developers in the MVS, DB2, IMS, LINCS, LU6.2 areas;

production support to identify the performance and contention

problems; evaluation and implementation of new software packages to

improve the system performance; collection of MVS and DB2 statistics

for overall CPP performance and individual transaction, batch job

performance; producing performance measurement reports and charts to

identify the areas with high system resource usage and working as a

- 8/91

- Provided DBA and technical support to a DB2 application, CIS. This

system used client/server architecture. The application was written in

C language on UNIX. The transactions entered on UNIX went through

LU6.2 and invoked CICS transactions to execute the remote DB2/SQL

statements. My functions included working as a team member on the

logical/physical data base design, working with developers on SQL

calls, working with Mesa data center on establishing a new DB2

environment for the system, coordinating the effort of moving software

from Orlando test system to Mesa data center, etc. I was also

responsible on studying and investigating the open gateway vendor

products. The purpose was to find the best architecture that would

provide the connectivity among multiple platforms. The vendor products

which had been investigated included Oracle's SQL * Connect to DB2,

Sybase's Net Gatewy, Open Gateway to DB2, AT&T's Lincs, etc.
