IMS Challenges

Connectivity– Need a way for both transactions and data to be exposed for

integration into enterprise applications– Bi-directional access between IMS and distributed platforms

Data Representation– Need to be able to easily share IMS data despite language,

platform dependencies– No change (or small change) to existing assets

Application Development– Mainframe skills (e.g. COBOL and PL/I) are becoming increasingly

harder to find– Need to keep up with industry languages and support emerging

application development tools

p. 4

IMS SOA solutions

Leverage on standards– SOAP, HTTP, XML, XQuery, WS-*, Java EE/JCA

SOA access to both IMS TM and DB

Protect existing IMS assets and encourage new IMS development– Leverage and reuse existing IMS transaction and data

Ease integration with other products and appliances– Microsoft .Net, SAP, etc...

Integrate with other IBM solutions– DataPower and WebSphere servers– Rational and WebSphere tooling

Enable our customers to continue to leverage IMS as an integral part of their enterprise in the evolving business world through the addition of support for complimentary standards surrounding IMS

connectivity, data representation, and application development

Upcoming IMS V10 SPE - IMS Connect API

Provide API to simplify use of IMS Connect by RYO applications – Currently, RYO client developers must understand intricacies of IMS

Connect headers (IRM, CSM, RSM, etc.) and message protocols– Intended for all customers who write client applications that interact

directly with IMS Connect (IMS Connect clients that do NOT use IMS TM Resource Adapter or IMS SOAP Gateway)

IMS Connect API will – Shield customers from dealing with IMS Connect headers and

protocols as well as TCP/IP sockets programming– Allow RYO client developers to configure an interaction by setting

attributes values which describe the type of interaction to be performed

– Execute interaction with Connect and return response to client

Goal is to support all available IMS Connect functionality in stages

Access from IMS database from– IMS dependent regions, WAS z/OS and distributed, CICS, DB2 stored

procedures

Language interoperability– Ability for Java and OO COBOL to invoke one another within the same

transaction

DB2 interoperability– Allow the use of either the DB2 JDBC or SQLJ– DB2 and IMS activity in the same unit of work– Return IMS data to a DB2 Java stored procedure encapsulated in a DB2

result set

Java TM and DB API– IMS message queue processing, program switching, etc

JDBC driver for IMS– SQL access to IMS Data

p. 48

Customer example – IMS Java API

Who?– German bank

• Mainly PL/I based with conversational transactions

Situation– Purchased 3rd party credit checking technology as part of a Java

package• Replaced existing PL/I-based transaction

– Wanted to deploy this in a Java Dependent Region and integrate with existing PL/I applications

• Just another service…

Solution– Leverage the deferred program switching support already in IMS

(and supported within the Java class libraries) to switch conversation iterations from MPP to JMP regions and back

– In production within a month with this solution

p. 49

JDBC (Java Database Connectivity)

Defines a standard Java API for accessing databases

Provides an API for sending SQL statements to a relational database and processing the tabular data returned– Wait a minute…IMS is hierarchic– More on this later

JDBC application model– Establish and open connection to database– Execute query and obtain results– Process results– Commit the results– Close connection

Provides application interoperability

p. 50

SQL and IMS

SQL is an extremely powerful query language– Designed to be usable for all database types– Multiple ways to write queries that return the same

results• Can prove costly with inefficient queries

– IMS JDBC supports subset of SQL syntax• Limit function to what IMS DBMS can do natively

p. 51

IMS DB Resource Adapter

IMS provides a JCA resource adapter for deployment in a WebSphere Application Server runtime– There is also an IMS TM resource adapter that provides J2EE

platform access to existing IMS transactions

JCA interaction ultimately provides the application with a JDBC Connection to an IMS DB– A direct connection to an IMS database– Applications can directly query and manipulate IMS database

information using JDBC with both SQL and XQuery

p. 52

Features

Supports J2EE Connector Architecture (JCA) 1.0

Connection Management– Connection pooling

Supports various types of interactions and programming models– JDBC

• SQL and XQuery support– Java for DLI

Security Management– RACF for authentication– ODBA does additional check for PSB (database) authorization

Transaction Management– Global z/OS RRS transaction support

Leverage and expose IMS data in a distributed topology– Enable creation of services that expose IMS data to distributed

platforms • PSB authorization still applies!

Distribution of database assets comes in two flavors– Distribution within an IMS plex

• Applications on one LPAR can access an IMS database on another LPAR

– Distribution to non-zSeries platforms• Applications on a non-zSeries platform can have direct IMS DB

access without needing an IMS transaction to proxy the data

IMS Connect will be the gateway to IMS DB as well as TM

Customer example – IMS DB RA

Who?– One of the world’s largest public corporations by revenue

Situation– Wanted to move to a web-based J2EE model in order to manage

internal inventory across their 4 regions in the United States

Solution– Leveraged the IMS DB resource adapter in order to develop

Enterprise JavaBeans that could access the target IMS databases directly

– WebSphere Application Server for z/OS V5

IMS XML Database Support

Introduces a way to view/map native IMS hierarchical data to XML documents– Aligns IMS Database (DBD) with XML Schema

Allows the retrieval and storage of IMS Records as XML documents with no change to existing IMS databases

Enables query of IMS data using XQuery

XQUERY - an evolvingstandard API designed to query and format XML data

IMS XQUERY processor- Extends IMS XML DB- Uses XML schemas generated by DLIModel

DLIModel Utility

IMS database visualization tool– Visualize an entire IMS PSB– Can view each PCB individually

• Hierarchy, segments, fields, types, etc

IMS database metadata generation tool– Generates the necessary metadata that

is consumed at runtime by IMS DB Resource Adapter, XML-DB support

• Database metadata• XML schema

Bottom up tooling approach– Parses PSB and DBD source– Optionally COBOL copybook

definitions of segments

Pushing Data Out

IBM solutions – IMS Architecture capability – Data Capture Exit

• Supports – Synchronous capability

• Extension to the IMS application as an exit routine (no change to application)

• ISRTs ALTPCB, db calls, MQ calls, Socket calls, etc. – Asynchronous capability

» Data Capture Log records – x’99’– WebSphere Classic Event Publisher for IMS (5655-M38)

• Leverages the IMS Data Capture architecture– Captures changes made to IMS files using an IMS logger exit

• Captured changes are reformatted into a relational data format – The relational format data is packaged as a self-describing XML

message – The XML messages are published to WebSphere MQ

Final Thoughts

With SOA you are looking to build a reuse culture

All roads lead to the people– Everybody gets involved in SOA – need to work across

organizations

SOA is a journey, not a one-time project that a single department implements

Corporate-wide process– Leverage technology in a way that reflects the business’s

key business processes– Enable business to change when needed without being

constrained by IT

IBM (and IMS) are here to support you every step of the way
