Redundant Array of Independent Disks (RAID) technology is becoming a standard feature of computer systems that support mission-critical services like file sharing, mail exchange, or Web servers. RAID offers two benefits to these essential systems: improved I/O performance and fail-safe data storage. Although bandwidth problems on networks are well documented, the internal data transfer bottleneck that exists at the hardware level in each system can also leave you with perplexing performance issu...

This is the eBook version of the printed book. If the print book includes a CD-ROM, this content is not included within the eBook version. Without a framework for organizing and codifying these ideas, systems modeling can become disjointed, frustrating, and ultimately ineffective. This book is extensively illustrated with detailed examples illuminating the main points discussed. Its four appendices provide fully worked examples of pertinent applications.

Provides a rationale for Open Systems and a view of the current state of Open Systems technology and the forces driving it into the market place. Emphasis is placed on the critical issues of migration and the integration of Open Systems with installed bases of proprietary systems. A description and objective analysis of IBM's current strategies in each area are also included throughout. The book is divided into two parts, one aimed at top management and focusing on strategy, and the other dealin...

DESCRIPTION Nim is a new general-purpose programming language that offers support for systems programming, object oriented programming, procedural programming, functional programming, and more. Nim combines the speed of C with the expressiveness of Python and the flexibility of Lisp and it compiles to C as well as C++, Objective C, and even JavaScript. Nim's features make it perfect for developing anything from web applications to operating systems. Nim in Action introduces the Nim programming l...

Including information on CICS/ESA Version 3, this book covers: program control, including the use of CALL, XCTL, and LINK with and without COBOL II; programming with DB/2 and IMS/DLI; file control with native VSAM files, including virtual storage utilization and performance enhancement hints; storage control including programming with DFHCOMMAREA, temporary storage, and other internal CICS storage; and CICS/ESA Version 3 enhancements to the command-level interface.

This tutorial covers important aspects of VSAM, including VSAM's role in some of the most common software proucts used in the IBM mainframe environment (CICS, IMS, and DB2). For each topic covered, the book identifies significant advantages and disadvantages, including probable changes. This introduction to VSAM looks at its internal structure, discussing the IDCAMS utility programs and several closely related topics. The text also emphasizes the processing of VSAM data sets in an application pr...
