Who am I?

● 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?

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.

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.


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?


30 years ago she met the current trend.

So did your Mainframe.

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

Isabel, the lame duck or: How I met COBOL(nothing to do with http://knowyourmeme.com/memes/duck-face)

You are a Mainframer if…

COBOL is not a foreign language for you.

You think that fixed font, green on black is an ideal programming environment.

IMS as well

AdministratorsDevelopers

Eclipse(development)

Web Browser(administration)

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


DB2 and IMS connections to execute SQL

Different projects

Graphical DBD view with logical relationshipsCopybook mapping in DBD

SQL to DL/I call translation information

IMS Explorer for Dev with or without Catalog


IMS Explorer for Administration – The Vision

Provide IMS system programmers and DBAs a state-of-the-art user interface to manage, configure, and deploy IMS systems

Full operational control over all IMS address spaces

Full command of IMS resources– Programs, transactions, databases, etc

Immediately react to and resolve issues in the system

Cloud-style IMS system management– IMS region profiling, application profiling, application deployment

Software requirements– IMS Tools Administration Console

• Component of IBM Tools Base for z/OS, V1.4 (no-charge)– IBM IMS Explorer for Administration

• Available through APAR PM94292 on IMS Tools Administration Console– IMS Version 12 & IMS Connect

• Common Service Layer OM and SCI– Supported web browser: Firefox, Internet Explorer, Safari


IMS Explorer for Administration - Capabilities

Enterprise System View– IMS Resource and IMSPlex discovery– Hierarchical representation starting from the

SYSPLEX to the IMS Resources

Enterprise Search– Search across the entire enterprise on any

type of resource

Visual Status– Quickly see the status of any IMS Resource

with colored status icons– Hover and click status icons for reason

codes and corrective actions– Filter IMS Resources

Manage IMS Resources– Start/Stop and update IMS Resource

Attributes– Multi select IMS Resources to manage and

update

Resource Relationships– View relationships between IMS Resources– At a glance understand why a transaction is

having a problem

Customize – Change the column attribute defaults

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
