IBM Software Group Asset modernization Challenge of managing knowledge assets What you have… What you want… • A diverse application portfolio evolved over many years and understood by few • Complexity hindering the ability to gauge the impact of code changes resulting from new requirements • A lack of documentation that limits reuse of existing business rules embedded within code Is this valuable? C++ AJAX DB 2 IMS/DB VSAM COBOL Could this be a business rule? CICS/IMS Data • An inventory of existing highly stable code that embodies enterprise business intelligence • Ability to understand manage application complexity and change by making dependencies visible • Identify and document existing business rules and business processes Potential order entry service EJB COBOL Java What happens if I change this? C++ 120 parts change if I modify this AJAX Asset Inventory EJB CICS/IMS Java Gold customer qualification rule Analyst studies have found it 5 x less expensive to re-use existing applications than to write new applications. “Knowledge may be the most the Solution Family of competitive advantage for a firm, but capturing the potential Corporation © 2007 IBM 3 Positioning important source gains is a continuing challenge”.

IBM Software Group Comparing CICS IA and WSAA+RTW CICS IA Primary target customers WSAA & RTW CICS Transaction Server customers, who need detailed understanding of their CICS applications (same business drivers as WSAA & RTW) CICS customers with a Sysplex who need workload management for high availability Enterprise customers with a large portfolio of mainframe applications and the requirement to transform these applications and the development process associated with them. Target audiences within these accounts: business analysts, system analysts, developers, testers Target audiences within these accounts: system analysts, system programmers, testers Primary use of products by customers Identify the runtime application behaviour and resource usage in CICS. Provides accurate and detailed information about the workloads run in a particular region. Resource relationships can also be viewed by application (user-defined). Mainly used for understanding, splitting workloads across multiple regions to enable high availability of CICS. Rapid application understanding, impact analysis across the application (and the enterprise), and assisted transformations of specific programs. Provide a common point of access to this application metadata. Particularly used for modernizing legacy applications with development tools like RDz. How does the product work Runs in the CICS production regions in real time, records CICS commands and associated data Source code is not required Scans in the source code into a repository for interactive or batch analysis. Type of information provides CICS – runtime view of bindings (e. g. program autoinstall and ISC), and application behavior including CICS calls into related subsystems (DB 2, IMS and Web. Sphere MQ) from CICS. Includes resources associated with transactions, programs, Basic Mapping Support (BMS) maps, files, TSQs, TDQs, 3270 Bridge facility, Web Services, Corba. Server, and Enterprise Java. Beans (EJBs). View of enterprise on-line and batch applications and their program and data interdependencies based on analysis of the source code and sub-system configurations. Multiplatform (z/OS and distributed (Java EE)) For CICS regions, ttransactions, programs, BMS maps, PDS, CICS TSQs and TDQs, I/O record descriptors Product Architecture ISPF administration of runtime collectors Data stored in DB 2 on z/OS Primary user interface: ISPF panels, batch reports, Eclipse client GUI Administration through ISPF panels and Web-browser Data stored in DB 2 on z/OS Web. Sphere Application Server provides user interface and impact analysis engine Primary user interface: web browser; custom batch reports possible Complementary positioning Can be positioned complementary to WSAA to gain additional buy-in from the Application Developers, and increase chances of closure. However, system programmers should already be on board. CICS IA can add value for the tasks analysts and developers using WSAA and RTW by providing additional information for a “fuller picture”: §When source code is missing §Real-time control flow, as in CICS control flow can be changed in runtime via exits, so CSD and the source code do not necessarily reflect the reality §To identify ‘potentially’ dead code for further investigation. CICS IA shows when a resource was last used §WSAA provides … §a view of application relationships not observed by the runtime collectors §Information about non-CICS assets (e. g. batch programs) with dependencies on CICS programs and data stores 16 Positioning the Solution Family © 2007 IBM Corporation
