July/1990 - Present TITLE: Unix Systems
Engineer, Network Systems Programmer, MVS Systems Programmer
My primary responsibilities include planning, installing, customizing,
and maintaining large-scale Unix base systems such as the AIX
Operating System for the RS/6000 J40 (an 8 CPU system) with a TCP/IP
LAN and Internet WAN, the Unix Pyramid Nile Operating System (a 4 CPU
RISC system) with a TCP/IP LAN and X.25 WAN (these are NFC 2 largest
Unix systems), and the Sun Solaris Sparc server with a TCP/IP LAN and
Internet WAN. These duties also include supporting the development
staff Application System Division (ASD) with the compilers (COBOL, C,
C++, Perl), with Korne Shell scripting, and with connectivity
solutions (TCP/IP, FTP, Telnet) to other systems and applications. For
each Unix system, my duties begin as a project assignment from the
planning and procurement stage of the hardware and software and
followed through until the system and application(s) are in a
production-stable state. From the planning stage, my responsibilities
entail researching several hardware and software components and
recommending solutions and alternatives that best address NFC system
and application needs to my management and procurement staff. Once
procured, my duties entail the implementation of the system by
following NFC ADP guidelines such as segregating software and hardware
components that require serialization versus parallization,
coordinating with other team members and management of the state of
the system, and postulating approaches and/or circumventions to ADP
problems to prevent delays or alterations to the project. Once in a
production stage, my responsibilities include maintaining the system
software on a regular and as needed basis. Such maintenance includes
applying patches and program temporary fixes (PTFs) on a test system,
and then applying them to the production system. My duties require
evaluating the impact of the maintenance and determining if such
impact should be pursued as a project. In such event, I make a written
or verbal recommendation to management. Upon management's approval, my
duties entail a project plan to be derived and executing the plan.
Some specific duties of the project and maintenance cycle that I am
responsible for include tuning and rebuilding the Unix kernel and
system parameters; allocating and optimizing virtual memory (paging
and swapping); defining and adding the Unix host and network
components and LAN daemons (printers, terminal servers, X-terminals)
to the TCP/IP Ethernet and FDDI LAN as well as the Internet WAN;
trouble-shooting any problems associated with the system; tightening
security on both the host and the network as per ADP guidelines
including configuring C2 security parameters with the security
officer; configuring the entire file system disk layout (raw disks,
virtual disks, and network file systems - NFS); and writing or
modifying system code written in C and/or Unix shell script (Korne
shell, Borne shell, and C shell). Some code modifications include the
system's startup and shutdown scripts to comply to Network Control
Center's (NCC) needs, the C2 security package to adhere to NFC's
security policy including pre and post login scripts for both the
ASCII terminal interface and the Motif and CDE graphical user
interface (GUI), Unix process accounting to retain over a year's worth
of accounting and statistical data needed for proper billing, and
correcting bugs on an emergency basis until a permanent patch is
available by the vendor such as the bug circumvention that I've
applied to the Computer Associate Unicenter software package.
Other duties that I perform include reporting to my management in the
form of reports, charts, and one-to-one meeting justification for
hardware, software, and network upgrades or changes in the current
operating mode of the system environment. Some of these reports
require analyzing performance data and capacity planning via Unix
process accounting, System Activity Reporter (SAR), Netstat, and other
performance monitoring and data gathering utilities. Also my duties
entail supporting the Oracle database administrators, providing an
optimized database disk layout which includes the configuration of the
disk partitions (determining virtual stripping, raw versus file
systems), installing and utilizing Oracle's PLEX (an Oracle database
package that extends Oracle's PL/SQL language via Database pipes),
implementing Oracle's startup and shutdown scripts into the Automated
Console Operation (ACO) software utilized by Network Control Center,
and writing Oracle systems programs in C, Pro-C, and PL/SQL code to
interface with data outside the Oracle environment.
As an MVS systems programmer, my primary duties were maintaining and
tuning Operating System related software packages, and troubleshooting
problems associated with these software packages on the IBM MVS
large-scale mainframe system. Such software packages, which were
mostly installed with the System Modification Package (SMP/E),
consisted of the following: Job Entry System (JES2), DFHSM, the COBOL
II compiler, TSO, ISPF, SPF, SMP/E, and Netview.
Current Assignments - I am currently the team leader for three
projects.
- The Unix backup/restore project: This project involves backing up
all the Unix servers and clients to a centralize Unix backup server
(using Alexandria, NFS, RedWood tape drives and a robotic librarian
system - Timberwolf 9745). The project includes backing up to the
mainframe (using FDR SOS) for disaster/recovery situations.
- The Pyramid Migration project: This project involves migrating all
applications and Oracle databases to the RS/6000 J40 platform.
- The RS/6000 and AIX Upgrade project: This project involves
installing IBM's largest Unix RS/6000 SMP server - the S70 Enterprise
system (12 CPUs, 4 GB memory, 1/2 TB RAID). This upgrade includes
installing AIX 4.3 (latest version), and migrating high volume Oracle
applications over to the new system.
Other projects: I'm on the team for Open Systems Year 2000 compliance.
I am researching the use of Network Information Systems (NIS) over
Computer's Associate's One-time logins.

Supermarket Mar./1988 - July/1990 TITLE: MVS & Unix Systems Programmer
Primary responsibilities included maintaining, tuning, and
trouble-shooting problems on the IBM MVS large-scale mainframe. Part
of the maintenance duties included upgrading the operating system with
SMP/E, defining hardware to the Operating System, tuning workloads and
performance groups (IPS,ICS), and optimizing datasets for better
performance. Other Systems Programmer responsibilities included
evaluating (written and verbally to management), installing,
upgrading, and customizing third party products such as Candle's
Omegamon for MVS, Landmark's CICS monitor, and Net-Session. Other MVS
duties included configuring, maintaining, and trouble-shooting
problems associated with VTAM, NCP, the IBM 3705 and 3725
communication controllers, and the IBM 3174 and 3274 cluster
controllers. Such configuration also included the definition of
terminals to CICS, defining printers to JES-328X, and resolving
communications problems associated with remote sites. Unix Systems
administrator duties were installing NCR Tower 32/600 systems which
consisted of fine tuning the kernel, installing the Unix O/S, device
drivers, TCP/IP SNA 3270 emulation program, SNA/RJE, and any
extensions. NCR Tower responsibilities were writing data conversion
programs in C, enhancing, modifying, and writing programs written in
RM-COBOL, C, and shell script, and setting up WAN networks for Unix
Tower to MVS mainframe communication
