CICS Portfolio e-Newsletter
June - July 2007
Welcome to the June - July issue. We hope you find this compilation of what's happening in the busy world of CICS and System z useful, informative and enjoyable.
More than 4000 IBM customers and Business Partners attended IBM IMPACT 2007 in Orlando US recently. This new, week-long event featured over 400 sessions aimed at business leaders, IT executives, technical communities, and those whose roles overlap the boundary between the business and information technology.
At the event, IBM announced a raft of new software and services, and customers had the opportunity to share their experiences on how adopting an SOA strategy has made an impact on their businesses which are now more innovative, flexible and efficient as a result.
CICS was well represented at IMPACT 2007 with sessions on CICS Transaction Server V3, a workshop on building and deploying Web services for use with CICS Transaction Server V3, and the 'birds of a feather' question and answer session on the future direction of CICS.
Over 4,500 IBM customers have already realized the benefits of moving to an SOA infrastructure and have ensured that their IT systems now more closely support the goals of their businesses. For these customers, adopting the SOA approach has resulted in more adaptable IT systems allied with cost savings and productivity improvements!
At the IMPACT 2007 Steve Mills, Senior Vice President, IBM Software had some important messages about why SOA has been a growth engine for IBM as well as for its customers, and how SOA gives businesses the flexibility to focus on achieving results without being restricted by technology.
There are many players in the SOA marketplace but the difference that IBM offers is the perfect combination of technical skills plus broad industry experience.

CICS Transaction Server for z/OS V3.2 and the enhanced CICS Tools become generally available on 29 June. This key event heralds one of the most important product releases for IBM and for IBM CICS customers in 2007.
The new capabilities introduced by CICS Transaction Server for z/OS V3.2 and the enhanced CICS Tools are found in the three key areas of application connectivity, application reuse and service management.
The delivery of CICS Transaction Server for z/OS V3.2 is IBM's response to the growing customer demand for the capability to build and run SOAs (Service Oriented Architectures) on the mainframe to protect existing technology investments. The success of the SOA approach is evidenced by IBM having recently reaching a milestone, with the adoption of SOA on the mainframe by 1000 of its customers.
The enhanced CICS Tools perfectly complement the new capabilities of CICS Transaction Server for z/OS V3.2 by enabling better monitoring and understanding of CICS applications and their performance. The updated CICS Tools also enable optimized IT resource usage, reduced operational costs and improved user productivity. Not a bad set of business benefits!

The editor asks...
In this new spot, we talk to a CICS expert. This month we hear from John Tilling who works in the CICS Technical Planning and Strategy group in Hursley. One of John's key roles is that of technical planner for CICS VR.
Editor: What is CICS VR?
John: CICS VR is CICS VSAM Recovery. It is part of the CICS Tools portfolio, but has been around since the late 1980s. It provides forward recovery support for CICS, back-out and forward recovery support for batch (without changing the batch application), and forward recovery support for the combined environment where a VSAM file is being shared by CICS VSAM RLS and a batch job using Transactional VSAM (TVS).
Editor: Is a forward recovery product still relevant today?
John: This question comes up a lot. The argument goes something like this... Storage subsystems and disk technology are so good these days that we don't need to bother... right? Wrong! Only recently, a customer trialling the latest release of CICS VR lost 40-50 datasets and used their production CICS VR to get them out of the hole. It does happen. I don't expect to crash my car, or let my house burn down, but that doesn't mean I don't have insurance policies for my car and my house! CICS VR is your insurance policy. Can you afford to lose integrity on your corporate VSAM data? Accidents happen, acts of nature happen, and sadly more malicious acts happen as well. I've even heard the 'storage technology is so good' argument taken to the extreme: a customer didn't even have the CICS VSAM files defined as backward recoverable. Boy, am I glad they don't manage my bank account!
Editor: What does forward recovery buy you?
John: As you know, CICS Transaction Server has recovery procedures to allow it to back out an abnormally terminating task, so the data is returned to its state at the last syncpoint. But what if the disk has crashed? The application will get an I/O error and abend, and when CICS tries to backout it too will get an I/O error. Now you have a backout failure, so how do you recover? This is where CICS VR comes in. CICS VR allows you to take the file offline, use a backup of the file and apply all the updates made to the file since the backup (using forward recovery records logged by CICS), and then bring it back online to CICS. Now CICS can retry its backout and the file is returned to its state at the last syncpoint. Integrity is restored. With CICS VR Version 4, there is even an autonomic capability between CICS VR and CICS TS to semi-automate, or fully automate this procedure, so recovery is initiated as soon as CICS detects a backout failure.
Editor: Can I afford the overhead?
John: Another misconception is that forward recovery logging is an expensive overhead. Unlike backward or undo logging where the before image must be on the system log before the vsam update can proceed, CICS TS will write forward recovery records asynchronously, and only harden them at syncpoint. The point being an in-flight unit of work can be recovered to the 'ragged end of the log' and then CICS TS will backout to the last syncpoint.
Editor: Is CICS VR being actively developed?
John: Yes indeed. We have delivered five releases over the last six years, the latest being CICS VR 4.2, available as of 27 April 2007, which is ready to provide day 1 support for CICS TS 3.2 when it GAs. This augments CICS Transaction Server's new extended ESDS support, plus batch and TVS capability and a host of other enhancements including integration with other IBM recovery products like ABARs.

Exposing applications as Web services with WSRR
The hundreds or thousands of services in a Service Oriented Architecture (SOA) require management and governance to realize the benefits of SOA, including service reuse and business flexibility. Product manager Sunil Murthy talks to CCR2's Carrine Greason about the enterprise-strength IBM WebSphere Service Registry and Repository for z/OS, a store for valuable metadata for exposing services and governing their lifecycle.
Distributed CICS extends its support to the HP Integrity Platform
Distributed CICS extends its support to the HP Integrity Platform; TXSeries for Multiplatforms is the distributed member of the CICS Online Transaction Processing (OLTP) products. TXSeries for Multiplatforms Version 6.1 now supports HP-UX on the HP Integrity platform, as well as the IBM AIX, Sun Solaris, Microsoft Windows, and HP-UX (PA-RISC) platforms. Version 6.1 is a key release, with a vastly simplified infrastructure through the removal of DCE and Encina, and significantly more powerful administration capabilities through a Web-based administration console. Why not try out the enhanced user experience of TXSeries V6.1 for yourself.

Training and development
Addressing the skills problem
Traditional core CICS skills that have been in demand for many years are still relevant in today's demanding business world. One area where IBM anticipated a possible problem is where traditional CICS applications that were developed a long time ago need to be modernized for use in today's fast-moving, Web-based business environment. The skills needed to do this are in relatively recent technologies such as Java and Web services. To address this issue IBM has put in place various initiatives with major universities. IBM also offers customers a comprehensive portfolio of CICS skills development activities in application programming, system programming, version-to-version migration and e-business.
