Technical Profile
Conversion of DB2, COBOL, PROCOBOL, CICS, MVS system into Oracle7, MVS-Client, People Soft Financials, Digital UNIX
(Alpha Server - OSF/1) environment. The MVS applications being converted numbered over 700 total (50 pilot) and these programs
were mainly responsible for order entry system, customer information, billing system and reports database. There were over 60 total
(15 pilot) vendor update programs being converted from MVS, as well as 30 total (10 pilot) RADICAL panels. I performed DB2 to
Oracle database migration utilizing oracle standard migration rules improvising in those areas where DB2 applications had special
external calls to the database. Oracle database was normalized then denormalized where application requirements called for it. With
use of desktop DBA and MVS client I was able to successfully perform DBA task while undergoing the conversion effort.
Database consisted of 128 tables with an average size of 4 gigabyte. Database conversion was first step in a redesign project for the
entire DB2 system. Project focused on all issues that would allow for a DB2 elimination within IS. Also setting up database so that
People Soft applications would receive data feeds from Oracle once DB2 data was loaded for end of month reporting and DSS feeds.
I was responsible for documenting the differences between DB2 and Oracle from a functional and a logical standpoint, as it applied to
the application requirements on MVS. Tools selection for client server interface on Digital UNIX platform on DEC Alpha Servers
and Pentium client under windows and NT. Redefine referential integrity according to application requirement and DB2 / Oracle
differences. Redefine batch process restart and delete rule violation messages. Finally migrate data into oracle with use of SQL
Loader direct load method with some BC copy loading by application.

Data Repository Development Data Warehousing/ Database Administrator / Infrastructure Development
/ Database Design - Design Validation
Review and validate Oracle 7.1.3 Data warehouse database designs from logical design to physical models (Erwin Designer -DDL
development). Setup multiple oracle instances on Windows NT and HP 9000 servers for multiple data feeds to data warehouse.
Oracle Data repository design and implementation with data replication through transparent gateways across multiple network
connections. Data and Meta Data was replicated into other Oracle instances and also into Personal Oracle7, MS Access and Oracle
databases running on NT, HP and AIX platforms.
Working with applications group, I also help setup GUI interfaces with database applications. Utilizing Visual Basic 3 and Visual
Basic 4 code, I setup all communications via ODBC,SQL Net and TCI/IP between Oracle and the end user applications. Environment
was a three tier setup with HP Unix as the baseline operating system and Windows NT as the middleware for the legacy systems and
applications and the GUI front end.
DB2 database design review in retrospect of the Oracle applications. In addition, I performed DB2 data conversions into Oracle and
mainframe application conversions into Oracle, Windows NT, HP UNIX and Visual Basic 4.0 environments. I performed straight data
conversions and data extracts from DB2 into Oracle databases. Oracle database designs were conformed by the DB2 applications and
the business rules as they applied to the data requirements of the applications on the legacy systems being converted.
Oracle 7.1.3, PL\SQL 2.0, SQL PLUS 3.1, Forms 4.5, Oracle CDE Tools (Oracle Procedure Builder, Oracle Browser, Oracle Data
Query, Oracle Report Writer...) Designer 2000, Oracle Enterprise Manager (Early Edition); Obackup (RMAN); Erwin 4.0, HP UNIX,
Open Windows(SAM), Exceed 4.0, TCP/IP. Hardware platform is a HP 9000(UNIX), RS/6000(NT) dual ported w/TCP/IP
connection to Novel LAN Network. I also utilized InfoBuilder, Oracle CASE designer, Oracle Data Dictionary rel 5.x, SQR, ADW
database designer, DB2, AIX UNIX and VSAM.
AT&T
Database Administrator / Infrastructure Development / Internet (Netscape)
October 1995 - January 1996
Administration of Oracle 7.1.6 database running on Sun Sparc 1000 servers under Sun Solaris 2.4 and SAM / Open Windows for Sun.
Installed Oracle Software to work on top of a Netscape transaction server behind a fire wall. Oracle database would serve as a data
repository and only be accesses in one direction. Fire wall kept database invisible to web browsers and company personnel. I also
installed a Netscape Transaction Server, Commerce Server, Content Server and Publisher Server. These servers served as the visible
back end of the system, while the Oracle Server served as the most sensitive piece of the back end process. The front end server was a
Netscape Content Server with multiple domains defined with the Wide World Web browser installed for local and remote access.
Setup all Oracle environmental parameters and all Oracle network protocols (SQL Net v 1 and 2) to work with Netscape Transaction
Server directly and the entire Netscape environment through telnet or Exceed x-sessions indirectly. Sun Solaris 2.4 and Open
Windows served as the UNIX environment along with Windows 95 and Netscape as the front end of this system.
