Who am I?
Isabel Arnold
● IBM CICS Technical Sales Germany since 2004
● Has a weakness for
● using a mouse (expert in Repetitive Strain Injury…)
● Hats
● Lego
● Bad humour

Objectives – Who are the musketeers?
Porthos & Athos: System Programmers
& Application Developers have been
working on and fighting for the mainframe
for ages, armed with console based
screens like ISPF and keyboards.
AraMis: For quite some years they are in good company
with the host modernizer,
● similarly armed
● connecting the mainframe to the outside world using new
technologies like Web Services, JCA or Web 2.0.
● But times are changing making it harder and harder
especially for the last one of the three musketeers to keep up
to date with evolving trends using their traditional weapons.
 The time is ripe for new gear including mouse and graphical interfaces.
 Join the speaker trying to walk in each one’s shoes carrying new weapons (based on eclipse
and web interfaces) and taking her hat off to them.

Trying to be a musketeer
No, it‘s a CICS girl !!!
Is it a
trade
show
hostess?
Is it a
physical
therapist
for treating
back pain?
Is it a
teacher?
Is it a
secretary?
Is it a
waitress?

Perceived appearance of a CICS girl
30 years ago she met the
current trend.
So did your Mainframe.

Sun's New Eco-Friendly Datacenter
http://www.theregister.co.uk/2009/01/27/sun_broomfield_datacenter/

You must be a Mainframer if …
1.You really thought long and hard about naming your dog FICON
2.You know your machine knew how to "phone home" way before E.T.
3.You can spell anything in eight characters
+ You can make a sentence out of just acronyms, and your peers
will understand it perfectly
4.You don't trust any machine you can lift or step over
5.You remember 1964 for the S/360 and not the Mustang
6.Your field engineer has ever shown up with parts to fix your
computer BEFORE you even know it was broken
7.When someone mentions green card, you don't think of immigration
8.You understand how a computer can work better with 150 liters of
water in it
9.You don't think of JECL as the other personality of Hyde

If you are a Mainframer you must be ...
25 - 35 years
36 - 45 years
46 - 55 years
>55 years

to keep your resources
together

to get them into (and

–Program not required in this bundle
 URIMAP* resources providing URIs for

–Unique name (still) required

IMS as well
 Modern Graphical User Interfaces
– Provide a richer user experience, can convey more information
– Reduce the need for IMS or z specific knowledge
– Shorten the IMS learning curve for new DBAs
– Enable deeper integration between tools and across platforms
– Customers expect it!!
 Leap ahead to Graphical interfaces for IMS
– Focus on Web-based interfaces for administration
– Focus on Eclipse-based interfaces for development
Developers Administrators

Platforms as deployment targets
 Abstraction layer to decouple applications <> CICS
topology complexity
 Consists of Region Types
– logical grouping collecting CICS regions with
common characteristics
– enables them to be managed as a unit in a platform
– Created: define a region type & set up new CICS
region definitions
– Adopted: adopt existing CICS system group
(CSYSGRP) as region type with its existing CICS
regions

Modern Application Interfaces – e.g. CICS
•Web services requester & provider
–Offers high Qualities of service, portability of
service, standard and comprehensive interfaces,
tooling, registries, extensibility, and simplicity
•JCA via CICS Transaction Gateway
–Offers high performance and Quality of Service,
standards, good tooling
•Messaging via WebSphere MQ
–Offers assured delvery, loose coupling, highly
perfomant asynchronous, efficiently handles very
large data
•HTTP / Atom / RESTful interfaces
–Offers simple & standard client interfaces, good-enough
qualities of service, some self-discovery
• IP Sockets via CS CICS Sockets
feature
–Offers complete customised protocol handling
NOTE: IIOP, ONC RPC, DFHWBCLI, CWI
COMMAREA and the Web server plugin
have been stabilised
