IMS Application Development Challenges

Difficult to test and deploy applications

Lack of integrated development solutions and tools

Difficult to find DLI programmers

Shrinking knowledge base around IMS &

hierarchical data base model

Fewer experienced COBOL and PL/I programmers

3 Separate Solutions or One Bundle

IMS Explorer – offers valuable functions to

modernize the database view – Free of charge

Debug Tool to make the application debugging

much more easier

Batch Terminal Simulator to let you debug in

your isolated world without disturbing anybody

RDz to integrate everything of this in only one

interface.


First solution : IMS Explorer

� Free and easy to download from IBM.COM/IMS

� Last version from DECEMBER 2011

� Some functions can be used with IMS V10

� Fully compatible with IMS 12


IMS Explorer … two offerings

� Stand-alone offering

� Shell-sharing offering for use with RDz 8.0 or Optim Development Studio 2.2.1.1 or later


Software Requirements

� The IMS Explorer supports IMS Version 10 and later

� To import COBOL and PL/I data structures, the IMS Explorer must be installed into Rational Developer for System z Version 8.0 or later

� For SQL access to an IMS database from IMS Explorer, you must have IMS Version 11 or later on your host system– Your host environment must be configured to support the Open Database enhancements

� If you have a Technology Preview version of the IMS Explorer installed, you must uninstall it prior to installing Version 2.1

� The IMS Explorer supports cross-product integration (shell-sharing) with the following products:– Rational Developer for System z Version 8.0.3 or later– IBM® Optim™ Development Studio Version 2.2.1.1 or later– IBM Problem Determination Tools Plug-ins for Eclipse

Introducing IMS Explorer for Developers…

� Easier visualization and editing of IMS Database and Program (PSB) Definitions

– Provide graphical editors to: *• Display IMS database hierarchical structures• Display/create/edit PSBs• Change/add fields on a DBD

– Import COBOL copybooks and PL/I data structures to a database segment *– Generate DBD and PSB source

– Generate metadata needed by Java applications and for SQL access from Explorer

� Ability to easily access IMS data using SQL statements *– Leveraging IMS 11 Universal JDBC driver and Open Database

� Connectivity to the z/OS system *– Browse a Data Set and submit JCL

– Import and export DBD and PSB source files from a Data Set to the IMS Explorer, and

vice-versa

Second Solution : IBM Debug Tool (DT) for z/OS

� Program product - PID : 5655-W45

� Help developers debug applications running in a variety of environments, such as batch, TSO, CICS, IMS, DB2, DB2 Stored Procedures, and UNIX System Services.

� Provides an interactive, full-screen, IBM 3270 system-based terminal interface with four windows that enable single-step debugging, dynamic patching and breakpoints.

� Also provides a plug-in GUI interface provides a debugging capability similar to thatthe ISPF interface

Debug Tool – General functions

� Characteristic– Go back and execute again– Automatic monitoring of COBOL and PL/I

variables – Fault Analyzer Interface – Code coverage utility– Identification and conversion to COBOL

(ANSI 85) from OS/VS COBOL– Programs preparation and compilation

utilities

� Supported environments :– CICS, TSO, JES/Batch, IMS including

IMS/TM, DB2 including stored procedures, Unix System Services, Websphere MQ

� Supported languages:– COBOL, C, C++, PL/I, Assembler

� Interfaces :– Terminal Interface Manager (TIM)– VTAM terminals (MFI)– Eclipse (Rdz or Explorer)– Batch

Step by step debugging at the source applicationMultiple breakpoints:

• instruction• changes on a storage address or variable• call or routine entry point

Third Solution : IMS Batch Terminal Simulator

� Program product - pid 5655-BT4

� Testing and debugging tool for IMS applications– Runs in TSO like an IMS Batch (DL/I or DBB) or IMS Online (BMP or JBP)

– Transparent testing of application programs

– No changes to IMS code, control blocks, libraries, or application load

modules are required

� Input message sent from : – BTS 3270 console running in TSO foregroung

– Batch

– BTS eclipse interface if integrated with RDz

� 3270 input message with formats sent without using any VTAM terminals• Simulating through control statements or interactive TSO full screen • Recording the terminal output image
