IMS Application Development (AD) Challenges

Shrinking knowledge base around IMS &

hierarchical data base model

Difficult to find DLI programmers

Lack of integrated development solutions and tools

Difficult to test and deploy applications

Fewer experienced COBOL and PL/I programmers

IMS Enterprise Suite Explorer for Development Easier visualization and editing of IMS Database and Program

Definitions – Provide graphical editors to:

– Display IMS database hierarchical structures– Display/create/edit PSBs– Add/Edit fields in DBDs

– Import Cobol CopyBooks and PL/I Structures into database segments– Generates DBD and PSB source for Catalog or non-Catalog enabled

systems.

Ability to easily access live IMS data using SQL statements. A graphical SQL statement builder is provide to help beginners.– Leveraging IMS Universal JDBC driver

Connectivity to the z/OS system– Browse a Data Set, submit JCL jobs, and view job output.– Import DBD and PSB source files from a Data Set to IMS Explorer, and

export generated source back to the host.

IMS Enterprise Suite Explorer for Development cont’d

Catalog Navigation view

– Navigate through the PSBs/DBDs on a given IMS catalog. Search based on partial resource names or built in queries and then import resources for editing or launch graphical modeling editors in read only mode.

Transaction unit test support

– Create a bucket of test cases with a UI enabling you to easily tweak input messages to test different code paths in your transactions and inspect transaction output messages.

Maps•Mapping support

–A Map is metadata that describes how a field (or set of fields) are mapped for a particular segment instance–Metadata captures the various cases and for each case defines the set of fields to be used for that case–Maps can be defined to the catalog–Maps are intended to be interpreted at runtime by the Universal drivers and the proper data elements are returned based on the runtime case of the segment instance–Example: Insurance segment mapped multiple ways depending on value of Policy Type control field

IMS Catalog Navigation View

Get a list of all the PSBs/DBDs in the system.

22

Built-in queries

Several built-in queries have been added to assist with resource and relationship discovery

– “What are all the PSBs that reference this DBD?”

23

Built-in queries continued

“What are all the DBDs referenced by this PSB?”

24

Graphically view resources directly from the IMS catalog

26

IMS Transaction Unit Test Support.

In a Transaction test project you can define a transaction

and import application data structures to specify the layout

of the input messages it consumes and output messages it

returns.

27

IMS Transaction Unit Test Support.

You can then create a test case to script a dialog between a

virtual client application and the transaction.

You can specify the input message payload.

Test cases can be duplicated and changed in order to build

up a test bucket to drive different code paths in the

transaction.

28

IMS Transaction Unit Test Support.

Use the runtime console

to tweak input message

field values, invoke the

transaction, and inspect

the output message.

Liberty z/OS Connect

A service that encapsulate calling z/OS target applications using REST calls. zOS Connect will support JSON payloads for calls from external

cloud or mobile-based clients and will enable the conversion of the payload to the target program's expected format. It will also provide the

response payload conversion from a byte array into JSON format before returning the response to the caller.
