From the IDC paper: “The Business Value of the Connected Mainframe for Digital Transformation” study, December 2016

• Modernize and create a platform that is

integration ready within and outside the

mainframe with Java, Linux, Web and API enablement

• Integrate mainframe with the rest of the datacenter infrastructure and IT processes with

Hybrid Cloud, DevOps and API/Mobile usage

IT staff productivity

$18M32%

Infrastructure cost reduction

IMS Middleware – All You Need in One

�A z/OS middleware that inherit all strength of IBM Z

�A Messaging & Transaction Manager–Based on a messaging and queuing paradigm

–High-volume, rapid response transaction management for application programs

accessing IMS and/or DB2 database, MQ queues

–“Universal” Application Connectivity – Inbound & Outbound

�A Database Manager–Central point of control and access for the IMS databases based on a hierarchical

database model

–“Universal” Database Connectivity based on JDBC / DRDA

–Eclipse based graphical interface for developers & DB administrators

�A Batch Manager–Managing the batch-oriented programs — providing checkpoint/restart services

–when accessing IMS and/or DB2 database, MQ queues

6


IMS – High level View

� IMS Transaction–No presentation layer–Very simple design

•Get Input Message•RM calls

•ISRT Output Message

– “execute” and “forget”

� IMS Batch–BMPs Msg Driven or non Msg Driven –Standalone (no picture here)

� Access to Resource Managers (RM)– IMS database – Hierarchical data model–DB2 database – Relational data model–MQ Queues–Web Services using WOLA – WebSphere

Optimized Local Adapter–JSON/Rest using z/OS Connect–Rules using zRES & ODM

� IMS Presentation Layer (MFS) –Description of input and output

messages and device map–Not used in client/server implementations

Inside IMS Apps

� An input layer processes the data coming from a client.

–At the end of this process we have an input area filled with EBCDIC characters.

� An orchestration layer analyses the input area and implements a sequence of calls to business logic.

–Usually subroutines ☺

� The business logic layer implements the service, directly calling resource managers

–To access and update data managed by DB2, VSAM, or IMS DB, or eventually send a message to MQ, taking care of delivery to the target resource manager.

� An output layer builds the data to be sent and finishes the unit of work.

–Options: Data is sent back to the client or sent to another IMS transaction (Prog to Prog)

–All updates are committed using the two phase commit protocol.

IBM & IMS Lab have been on a journey to transform IMS DB

12

2009 2011 2015

A developer can access IMS DB from any platform using industry standard APIs and syntax

Access Integrate Act

Open Database CatalogDynamic Change

& DDL

Developers, system programmers, and DBAs can integrate and connect IMS DB with standard tools for modeling, discovery and data insight

A DBA can evolve the IMS DB structure and schema using industry standard syntax without taking an outage

<meta>

2000

A developer can use Java language in z/OS applications to access IMS DB.

Open

Java JDBC


… and to provide a range of analytics solutions on IMS Databases today

72%say greatest value will come

from analyzing transactional data

Pain Point/Opportunity Solution

• Analyze IMS data with

unstructured data

Hortonworks & Big SQL

• Deep and fast analysis
