CICS / WebSphere

Applications that cross computing platforms or share processes and data with other applications communicate through a complex middleware layer. This middleware layer has traditionally been a software component, with IBM WebSphere MQ as the dominant platform. Now the IBM DataPower XI50 appliance provides middleware services as hardware. As DataPower appliances become more popular, IT organizations are supplementing their middleware structure with the functionality available in the DataPower boxes…

CICS Explorer was first released as a SupportPac nearly three years ago. Since then, it has continued to evolve, giving users a modern, intuitive, consistent interface to configure, administer, and create CICS applications. The first product release, CICS TS V4.1, covered a subset of CICS system administration topologies, providing access to Business Application Services (BAS) and CICS System Definitions (CSDs) for both standalone and CICSPlex System Manager (SM)-managed regions. During development of CICS Transaction Server (TS) V4.2, CICS Explorer was included in the design of each new function, consolidating its role as “the new face of CICS.” This article discusses the latest innovations in the product, which ensure that CICS Explorer will be increasingly valuable to CICS users…

How can you provide reliable, consistent access to your CICS servers? The High Availability (HA) functionality provided in z/OS, CICS Transaction Gateway (CICS TG), and CICS Transaction Server (CICS TS) supports duplication of services. This duplication removes single points of failure in the system while simultaneously projecting a single system to users. Choosing the topology used to create a highly available system will depend on the technology available and where redundancy is required. Why create a highly available topology?…

A traditional DBMS stores data that’s implied to be valid at the current point in time; it doesn’t track the past or future states of the data. Temporal support makes it possible to store different database states and to query the data “as of” those different states. Many types of data change over time, and different users and applications require access to that data at different points in time. For some, the current, up-to-date values for the data are sufficient. But for others, accessing earlier versions of the data is needed…

End-to-end application management and visibility are toward the top of the list for nearly every CIO. Why is this such a pressing problem, and why has IT been unable to solve it?

One major challenge is achieving end-to-end visibility of an application that provides a single point of control and a unified view of the application, regardless of the tools that IT staff employ to check or resolve application performance. The need—and the potential—for complete application visibility is even more keenly felt with the introduction of zEnterprise-class computing, which provides firmware-level integration across the IBM Systems p, x (x86), and z platforms through the IBM zEnterprise Unified Resource Manager (zManager)…
