Unlocking more value from legacy CICS applications

old-lockIBM’s acquisition of ILOG has resulted in a great new opportunity to unlock the business value of CICS applications by turning the COBOL logic into easy-to-read/edit ‘business rules’.

IBM has taken the ILOG JRules Business Rules Management System (BRMS) and made it part of the WebSphere family. But even better for CICS users, IBM has made this business rules capability available for CICS applications too. This whole subject is discussed in more detail in a new and free Lustratus Report, downloadable from the Lustratus web store, entitled “Using business rules with CICS for greater flexibility and control”. But why is this capability of interest?

The answer is that many of the key business applications in the corporate world are still CICS COBOL mainframe applications, and although these applications are highly effective and reliable, they sometimes lack in terms of flexibility and adaptability.┬áNot unreasonably, companies are loath to go to the expense and risk of rewriting these essential programs, but are instead looking for some technology-based answer to their needs for greater agility and control. The BRMS idea provides just that. Basically, the logic implementing the business decisions in the operational CICS applications is extracted and turned into plain-speaking, non-technical business rules, such as ‘If this partner has achieved GOLD certification, then apply a 10% discount to all transactions’. This has a number of benefits:

  • It becomes easy for rules to be changed
  • It becomes easy for a business user to verify the rules are correctly implemented
  • If desired, business users can edit operational rules directly

While BRMS is a technology with a lot to offer in many scenarios, it seems particularly well suited to legacy environments, providing a way to unlock increased potential and value from existing investments.
