Rational Developer for System z (RDz) overview What is RDz

Eclipse-based IDE speeding modern composite (SOA) application development

RDz supports Enterprise Modernization Supports common IDE for COBOL, PL/I, C, C+

+, HL ASSEMBLER, Java, and Web Services

Provides interactive access to z/OS for development, debug, job generation, submission, monitoring, command execution

Supports new and existing runtimes (CICS, IMS, Batch, USS, DB2 Stored Procedure, Application Servers.

Transforms UML to COBOL source code

Integration with z/OS tools

RDz supports SOA Enables CICS and IMS applications for Web

Services and SOA

Supports for J2EE, JCA, XML, Web Services


Legacy applications

● Rewriting - is it an option ? How long will it take? (lose strategic benefit)

Who will do it? (who has the business knowledge?)

How much will it cost?

Risk?

● Significant business intelligence exists in core systems* "200 Billion lines of COBOL code in existence" eWeek

"5 Billion lines of COBOL code added yearly“ Bill Ulrich, TSG Inc.

“2 Million COBOL developers" Gartner

"Majority of customer data still on mainframes“ Computerworld

“Replacement costs $20 Trillion” eWeek

Editor: Real-time syntax checking for COBOL

Benefit: Improve coding productivity.

Real-time syntax check without requiring code compile or save


Useful Eclipse features available to z/OS assets..Like Compare

Benefit: Improve productivity

1

Able to merge the differences using the icons

2


Useful Eclipse features available to z/OS assets..Like Replace with Local History

Benefit: Improve productivity saving recover time…

1

Keep as many local versions as you want and compare with the

z/OS current version..

2


Use local or remote compiler to do syntax checking

Local Syntax checking..

1

Just double-click to find the error

2

What is Service flow support?● Service Flow Feature is a CICS feature.

Service flow support is a Rational Developer for System z tool to build service flows out of your existing COMMAREA/container, WSDL and Terminal based CICS applications.

● It allows you to: Model business processes

Implement business processes by aggregating multiple transaction invocations, terminal interactions, and sub-flows

Deploy these aggregations to runtimes n CICS Transaction Server V3.x or WebSphere® Application Server

Optionally deploy business process as a web service

● Development concepts consistent with other SOA development tasks

● Support for Service Flow Runtime V3.2
