Marc Mérel

The following are more technical details to expand on my accomplishments
starting when I was hired by CN in 1980.

MVS:
First level user interface
Products installation and support.
Introduced ISPF DIALOGS facility to CN.
Designed the DIALOG ISPF sub-panel and tutorial.

VM:
Installation, maintenance, support and tuning.
Designed the "REROUTE" program to convert VM spool into MVS/JES spool.
VM Team Leader by 1983.

PERFORMANCE:
Performance Group Leader in 1984.
SLA: Set Service Levels with applications.
Network: Put in place an inter-group tracking mechanism.
Introduced the concept of CICS AM and PM to respond to low capacity.
I/O balancing, DASD and datasets moves for better performance.
Set up VAM/VDS pools strategy.
Estimated the MIPS requirements and identified potential bottlenecks
during project development like EDI and Electronic Commerce.
Evaluated multiple new products for functionality and performance.
Designed all performance and tuning for Indian railway.
Designed all performance and tuning for China railroad.

MICS and REPORTING:
Replaced Winnipeg data transmission from tapes shipped by plane by FTP.
Decrease DASD space usage by rationalizing the MICS database.
Implemented MICS database protection and backup.
Improved the Quarterly Executive Report.
Updated and improved reporting to Management and Applications.
Improved the presentation of data with the D.PERF panel for handy daily
reports as well as Email bulletin board and lately the TSSP INTRANET.

CAPACITY:
Planned future CPU and DASD capacity requirements based on trends
and changing applications demand.
FORST: Developed a model to measure latent demand on MVS computers.
WEIGHTS: Designed a weight/engines simulator to provide CN with the
first scientific recommendations for engine sharing and weights changes.

UNIX:
Implemented first CN Unix measurements by installing Patrol and SAR.
Set up Unix backup strategies and Unix Disater recovery requirements.
Designed ADSM scripts to backup and restore DB2/UDB archive logs.
Implemented first CN LAN measurements and surveyed LAN traffic for
all HP-Openview surveyed circuits.

SPECIAL PROJECTS:
Designed the "NODE TO NODE TRANSFER" and the "MAILAWAY" utilities
(used 830 000 times in 1999).

Wrote "CNTIME" program to calculate the Official CN processing date.

Designed the "ISPLLIB Technique", an important TSO response time improvement,

Designed CIS External Customers JCL to allow CN internal computers
modifications without having to affect Customer's on site set up.

Member of the Windows 95 pilot with a special focus on TSSP usage particularities.

DPR: Rewrote the DPR process to meet Y2K compliancy requirements,
adding new facilities and removing dependancies on Focus and Cobol.



Have been involved me with more technologies than most people in our group.
A prime responsibility in figuring out a performance bottleneck is to determine quickly
if the problem lies on the client workstation, in the LAN or the network,
or if the problem is within the mainframe. Then if is it the IMS, CICS or database etc...

Understand complex environments where tri-tiers and multiple interfaces are involved.
For instance electronic commerce timouts which involved mainframes, gateways, Unix,
Oracle and Java components.

Eager at getting projects started and fast at getting results.

Have contacts in most support and applications groups and know
who can provide expertise to solve specific problems.

Advantaged with real pedagogic qualities that make me a true asset
for providing direction, training and development for staff

My knowledge of CN Information Systems, my open mind and ease with many
technologies make me a prime actor in providing quality consulting
services and advanced technical support to Online Control, Operations and Applications.
