This IBM® Redbooks® publication describes the new channels and containers support in IBM Customer Information Control System (CICS®) Transaction Server V5.2. The book begins with an overview of the techniques used to pass data between applications running in CICS. This book describes the constraints that these data techniques might be subject to, and how a channels and containers solution can provide solid advantages alongside these techniques. These capabilities enable CICS to fully comply with emerging technology requirements in terms of sizing and flexibility. The book then goes on to describe application design, and looks at implementing channels and containers from an application programmer point of view. It provides examples to show how to evolve channels and containers from communication areas (COMMAREAs). Next, the book explains the channels and containers application programming interface (API). It also describes how this API can be used in both traditional CICS applications and a Java CICS (JCICS) applications. The business transaction services (BTS) API is considered as a similar yet recoverable alternative to channels and containers. Some authorized program analysis reports (APARs) are introduced, which enable more flexible web services features by using channels and containers. The book also presents information from a systems management point of view, describing the systems management and configuration tasks and techniques that you must consider when implementing a channels and containers solution. The book chooses a sample application in the CICS catalog manager example, and describes how you can port an existing CICS application to use channels and containers rather than using COMMAREAs.

Data security is one of the paramount requirements for organizations of all sizes. Although many companies invested heavily in protection from network-based attacks and other threats, few effective safeguards are available to protect against potentially costly exposures of proprietary data that results from a hard disk drive being stolen, misplaced, retired, or redeployed. Self-encrypting drives (SEDs) can satisfy this need by providing the ultimate in security for data-at-rest and can help reduce IT drive retirement costs in the data center. Self-encrypting drives are also an excellent choice if you must comply with government or industry regulations for data privacy and encryption. To effectively manage a large deployment of SEDs in Lenovo® System x® servers, an organization must rely on a centralized key management solution. This IBM Redbooks® publication explains the technology behind SEDs and demonstrates how to deploy a key management solution that uses IBM Security Key Lifecycle Manager and properly setup your System x servers.

The author presents a general view on sports training, its eriodization and the role of coordination in the initial stages of preparation in volleyball. He also deals with inter-gender differences in levels of such abilities, describing motor tests for the assessment of coordination potential and providing the reader with standards for the development of talented players. Based on the nature of volleyball, the author analyses key features of sports performance. Coordination abilities, especially in the period of puberty, play an important role in the creation of coordination basis – prerequisites for the development of physical fitness and acquisition of motor skills. Based on the results of his own research, as well as studies conducted by international sports scientists, he offers a model for the development of coordination abilities in volleyball. This method is recommended for coaches to improve their professional work in volleyball classes and schools, and in sports clubs. In the long-term, application of the proposed model should contribute to the improvement of players‘ performance in competition.
