news
SCO brings again UnixWare SCO community introduced lower back the once mainstay UnixWare moniker with modern unveiling of edition 7.1.3 of the operating system application, including uphold for open-supply methods just like the Apache web Server and boosting uphold for Java. The unusual version is the primary unveiled seeing that the acquisition of the former Santa Cruz Operation by way of Caldera in 2001 and the resolution to rename the joint commerce SCO group.
the unusual SCO UnixWare 7.1.3 is the successor unencumber to Open Unix 8 (aka UnixWare 7.1.2), and retains the talent to Run applications written for the open-source Linux working equipment. SCO officers mentioned that the unusual edition includes an replace to the Linux Kernel character (LKP) expertise, which allows systems to Run Linux necessities Base-compliant purposes on UnixWare; the company contends this provides a more scalable, sturdy and professional environment than Linux implementations delivery nowadays.
the unveiling of the unusual UnixWare edition coincided with the introduction of a unusual SCO update service, which officers spoke of can present company users early access to unusual SCO UnixWare features and performance by way of incremental characteristic enhancements leading to and including the next unlock of SCO UnixWare. SCO UnixWare help packs might be delivered on a 3- to four-month cycle. Chris Sontag, senior vp of SCO's working methods unit, famous operations utilizing the brand unusual carrier ''no longer requisite to wait the typical 18-month cycle to gain access to the unusual aspects they requisite to aid the deployment of these business-critical applications.''

The unusual edition begins shipping later this week, SCO officers mentioned. For greater suggestions, click on on http://www.sco.com/items

    Object-Oriented Frameworks for network Programming | killexams.com actual Questions and Pass4sure dumps

    This chapter is from the publication  1.four.1 a top smooth view of ACE ACE is a incredibly portable, customary, open-source host infrastructure middleware toolkit. The source code is freely obtainable from http://ace.ece.uci.edu/ or http://
    www.riverace.com/. The core ACE library includes roughly 1 / 4 million lines of C++ code that contains about 500 classes. many of these classes cooperate to shape ACE's foremost frameworks. The ACE toolkit additionally includes better-stage components, as well as a large set of examples and an extensive automatic regression verify suite.
    To divide issues, nick back complexity, and let functional subsetting, ACE is designed the expend of a layered architecture [POSA1], shown in determine 1.7. The capabilities provided by means of ACE span the session, presentation, and software layers in the OSI reference mannequin [Bla91]. The groundwork of the ACE toolkit is its combination of an OS adaptation layer and C++ wrapper facades, which collectively encapsulate core OS network programming mechanisms to Run portably on any of the OS platforms proven in Sidebar 2 (web page sixteen). The bigger layers of ACE construct on this groundwork to supply reusable frameworks, networked service add-ons, and specifications-based mostly middleware.
    Figure 1.7 device 1.7: The Layered architecture of ACE
    1.4.2 A Synopsis of the ACE Frameworks The ACE frameworks are an integrated set of courses that can besides be instantiated and customized to give comprehensive networked purposes and service add-ons. These frameworks assist to switch decades of collected talents directly from the ACE developers to
    Sidebar 2: OS structures Supported via ACE
    ACE runs on a large reach of operating methods, including:
  • PCs, for example, windows (32- and sixty four-bit versions), WinCE, and Macintosh OS X
  • Most models of UNIX, for example, SunOS/Solaris, IRIX, HP-UX, Tru64 UNIX (Digital UNIX), AIX, DG/UX, Linux (Redhat, Debian, and SuSE), SCO OpenServer, UnixWare, NetBSD, and FreeBSD
  • real-time working methods, for instance, VxWorks, ChorusOS, LynxOS, Phar-lap TNT, QNX Neutrino and RTP, RTEMS, and pSoS
  • tremendous enterprise techniques, for instance, OpenVMS, MVS OpenEdition, Tandem NonStop-UX, and Cray UNICOS.
  • ACE may besides be used with any of the primary C++ compilers on these platforms. The ACE web site at http://ace.ece.uci.educontains a complete, up-to-date checklist of platforms, together with instructions for downloading and constructing ACE.
    ACE clients in the shape of edge embodied in smartly-established and reusable C++ utility artifacts. The ACE frameworks implement a pattern language for programming concurrent object-oriented networked applications. device 1.8 illustrates the ACE frameworks. to illustrate how the ACE frameworks depend on and expend every other, the strains between packing containers signify a dependency in the direction of the arrow. each and every framework is printed under.
    Figure 1.8 device 1.eight: the primary thing Frameworks in ACE
    ACE Reactor and Proactor frameworks. These frameworks implement the Reactor and Proactor patterns [POSA2], respectively. both are architectural patterns that permit purposes to be pushed by using routine which are dropped at the application from one or greater event sources, the most essential of which are I/O endpoints. The Reactor framework facilitates a reactive I/O mannequin, with events signaling the talent to inaugurate a synchronous I/O operation. The Proactor framework is designed for a proactive I/O mannequin where one or extra asynchronous I/O operations are initiated and the completion of each and every operation triggers an adventure. Proactive I/O models can achieve the efficiency benefits of concurrency without incurring a lot of its liabilities. The Reactor and Proactor frameworks automate the detection, demultiplexing, and dispatching of software-defined handlers in keeping with many forms of hobbies. Chapters 3 and 4 represent the ACE Reactor framework and Chapter eight describes the ACE Proactor framework.
    ACE carrier Configurator framework. This framework implements the component Configurator sample [POSA2], which is a design pattern that allows for an application to hyperlink and unlink its fragment implementations without needing to modify, recompile, or relink the software statically. The ACE provider Configurator framework supports the config-uration of applications whose capabilities may besides be assembled late within the design cycle, comparable to at installation time and/or Run time. functions with towering availability requirements, corresponding to mission-important systems that duty on-line transaction processing or real-time industrial technique automation, frequently require such bendy configuration capabilities. Chapter 2 describes the design dimensions associated with configuring networked features and Chapter 5 describes the ACE service Configurator framework.
    ACE chore framework. This framework implements numerous concurrency patterns, similar to lively protest and Half-Sync/Half-Async [POSA2]. energetic protest is a design pattern that decouples the thread that executes a way from the thread that invoked it. Its goal is to augment concurrency and simplify synchronized access to things that live of their personal threads of manage. Half-Sync/Half-Async is an architectural sample that decouples asynchronous and synchronous processing in concurrent programs, to simplify programming with out reducing performance unduly. This sample incorporates two intercommunicating layers, one for asynchronous and one for synchronous carrier processing. A queueing layer mediates conversation between features within the asynchronous and synchronous layers. Chapter 5 of C++NPv1 describes the design dimensions linked to concurrent networked functions and Chapter 6 of this ebook describes the ACE chore framework.
    ACE Acceptor-Connector framework. This framework leverages the Reactor framework and reifies the Acceptor-Connector pattern [POSA2]. This design pattern decouples the connection and initialization of cooperating peer capabilities in a networked device from the processing they duty as soon as related and initialized. The Acceptor-Connector framework decouples the active and passive initialization roles from utility-defined carrier processing performed by means of communicating peer services after initialization is finished. Chapter 7 describes this framework.
    ACE Streams framework. This framework implements the Pipes and Filters pattern, which is an architectural sample that provides a constitution for techniques that system a circulation of records [POSA1]. The ACE Streams framework simplifies the evolution and composition of hierarchically layered functions, similar to consumer-degree protocol stacks and community administration agents [SS94]. Chapter 9 describes this framework.
    When used collectively, the ACE frameworks outlined above enable the construction of networked functions that may besides be updated and extended without the should adjust, recompile, relink, or restart operating applications. ACE achieves this unparalleled flexibility and extensibility by means of combining
  • OS mechanisms, such as event demultiplexing, IPC, dynamic linking, multithreading, multiprocessing, and synchronization [Ste99]
  • C++ language features, such as templates, inheritance, and dynamic binding [Bja00]
  • Patterns, equivalent to component Configurator [POSA2], approach [GoF], and Handler/Callback [Ber95]
  • The ACE frameworks deliver inversion of control by the expend of callbacks, as shown under:
    ACE Framework
    Inversion of handle
    Reactor and Proactor
    Calls back to utility-presented smack handlers to accomplish processing when activities Take plot synchronously and asynchronously.
    provider Configurator
    Calls lower back to software-provided carrier objects to initialize, droop, resume, and finalize them.
    project
    Calls returned to an utility-presented hook formula to duty processing in one or more threads of manage.
    Acceptor-Connector
    Calls back to carrier handlers to initialize them after they may be connected.
    Streams
    Calls again to initialize and finalize tasks when they're pushed and popped from a flow.
    The callback strategies in ACE's framework courses are defined as C++ virtual strategies. This expend of dynamic binding allows for networked purposes to freely enforce and lengthen interface methods with out modifying or rebuilding latest framework classes. In distinction, the ACE wrapper facades infrequently expend callbacks or digital methods, in order that they aren't as extensible as the ACE frameworks. The ACE wrapper facades upshot guide a broad reach of expend situations, youngsters, and can be integrated together via conventional programming [Ale01] strategies in response to the C++ qualities and traits classes idioms outlined in Sidebar forty (page 165).
    determine 1.9 illustrates how the classification libraries and frameworks in ACE are complementary technologies. The ACE toolkit simplifies the implementation of its frameworks by way of its classification libraries of containers, which embrace lists, queues, hash tables, strings, and other reusable facts structures. Likewise, utility-described code invoked through event handlers within the ACE Reactor framework can expend the ACE wrapper facades and the C++ universal library classes [Jos99] to accomplish IPC, synchronization, file administration, and string processing operations. Sidebar three describes a way to construct the ACE library so so that you can test with the examples they latest during this e-book.
    Figure 1.9 determine 1.9: making expend of category Libraries to augment and expend ACE Frameworks
    Sidebar 3: building ACE and classes that expend ACE
    ACE is open-supply utility that you should download from http://ace.ece.uci. edu or http://www.riverace.com and build your self. These sites embrace a wealth of different cloth on ACE, corresponding to tutorials, technical papers, and an overview of alternative ACE wrapper facades and frameworks that aren't lined during this e-book. you could additionally purchase a prebuilt version of ACE from Riverace at a nominal can charge. notice http://www.riverace.com for a list of the prebuilt compiler and OS systems supported via Riverace.
    if you requisite to build ACE your self, recollect to download and unpack the ACE distribution into an bare listing. The excellent-degree directory within the distribution is called ACE_wrappers. They mention to this top-degree listing as "ACE_ROOT." create sure you create an ambiance variable through that cognomen containing the complete direction to the suitable-level ACE listing. The ACE supply and header info live in $ACE_ROOT/ace.
    The $ACE_ROOT/ACE-deploy.html file has finished instructions for constructing ACE, together with a way to configure it in your OS and compiler. This publication's networked logging carrier illustration supply and header data wait in $ACE_ROOT/examples/ C++NPv2 and are ready to construct on any platforms that ACE supports. To build your own classes, the $ACE_ROOTdirectory Have to be delivered to your compiler's file encompass path.

    ACE Service Configurator framework. This framework implements the Component Configurator pattern [POSA2], which is a design pattern that allows an application to link and unlink its component implementations without having to modify, recompile, or relink the application statically. The ACE Service Configurator framework supports the config-uration of applications whose services can be assembled late in the design cycle, such as at installation time and/or Run time. Applications with towering availability requirements, such as mission-critical systems that accomplish online transaction processing or real-time industrial process automation, often require such flexible configuration capabilities. Chapter 2 describes the design dimensions associated with configuring networked services and Chapter 5 describes the ACE Service Configurator framework.
    ACE chore framework. This framework implements various concurrency patterns, such as active protest and Half-Sync/Half-Async [POSA2]. active protest is a design pattern that decouples the thread that executes a method from the thread that invoked it. Its purpose is to enhance concurrency and simplify synchronized access to objects that reside in their own threads of control. Half-Sync/Half-Async is an architectural pattern that decouples asynchronous and synchronous processing in concurrent systems, to simplify programming without reducing performance unduly. This pattern incorporates two intercommunicating layers, one for asynchronous and one for synchronous service processing. A queueing layer mediates communication between services in the asynchronous and synchronous layers. Chapter 5 of C++NPv1 describes the design dimensions associated with concurrent networked applications and Chapter 6 of this reserve describes the ACE chore framework.
    ACE Acceptor-Connector framework. This framework leverages the Reactor framework and reifies the Acceptor-Connector pattern [POSA2]. This design pattern decouples the connection and initialization of cooperating peer services in a networked system from the processing they accomplish once connected and initialized. The Acceptor-Connector framework decouples the active and passive initialization roles from application-defined service processing performed by communicating peer services after initialization is complete. Chapter 7 describes this framework.
    ACE Streams framework. This framework implements the Pipes and Filters pattern, which is an architectural pattern that provides a structure for systems that process a stream of data [POSA1]. The ACE Streams framework simplifies the evolution and composition of hierarchically layered services, such as user-level protocol stacks and network management agents [SS94]. Chapter 9 describes this framework.
    When used together, the ACE frameworks outlined above enable the evolution of networked applications that can be updated and extended without the requisite to modify, recompile, relink, or restart running applications. ACE achieves this unprecedented flexibility and extensibility by combining
  • OS mechanisms, such as event demultiplexing, IPC, dynamic linking, multithreading, multiprocessing, and synchronization [Ste99]
  • C++ language features, such as templates, inheritance, and dynamic binding [Bja00]
  • Patterns, such as Component Configurator [POSA2], Strategy [GoF], and Handler/Callback [Ber95]
  • The ACE frameworks provide inversion of control via callbacks, as shown below:
    ACE Framework
    Inversion of Control
    Reactor and Proactor
    Calls back to application-supplied event handlers to accomplish processing when events occur synchronously and asynchronously.
    Service Configurator
    Calls back to application-supplied service objects to initialize, suspend, resume, and finalize them.
    Task
    Calls back to an application-supplied hook method to accomplish processing in one or more threads of control.
    Acceptor-Connector
    Calls back to service handlers to initialize them after they're connected.
    Streams
    Calls back to initialize and finalize tasks when they are pushed and popped from a stream.
    The callback methods in ACE's framework classes are defined as C++ virtual methods. This expend of dynamic binding allows networked applications to freely implement and extend interface methods without modifying or rebuilding existing framework classes. In contrast, the ACE wrapper facades rarely expend callbacks or virtual methods, so they aren't as extensible as the ACE frameworks. The ACE wrapper facades upshot uphold a broad reach of expend cases, however, and can be integrated together via generic programming [Ale01] techniques based on the C++ traits and traits classes idioms outlined in Sidebar 40 (page 165).
    Figure 1.9 illustrates how the class libraries and frameworks in ACE are complementary technologies. The ACE toolkit simplifies the implementation of its frameworks via its class libraries of containers, which embrace lists, queues, hash tables, strings, and other reusable data structures. Likewise, application-defined code invoked by event handlers in the ACE Reactor framework can expend the ACE wrapper facades and the C++ gauge library classes [Jos99] to accomplish IPC, synchronization, file management, and string processing operations. Sidebar 3 describes how to build the ACE library so that you can experiment with the examples they present in this book.

    ACE is open-source software that you can download from http://ace.ece.uci. edu or http://www.riverace.com and build yourself. These sites contain a wealth of other material on ACE, such as tutorials, technical papers, and an overview of other ACE wrapper facades and frameworks that aren't covered in this book. You can besides purchase a prebuilt version of ACE from Riverace at a nominal cost. notice http://www.riverace.com for a list of the prebuilt compiler and OS platforms supported by Riverace.
    If you want to build ACE yourself, you should download and unpack the ACE distribution into an bare directory. The top-level directory in the distribution is named ACE_wrappers. They mention to this top-level directory as "ACE_ROOT." You should create an environment variable by that cognomen containing the replete path to the top-level ACE directory. The ACE source and header files reside in $ACE_ROOT/ace.
    The $ACE_ROOT/ACE-INSTALL.html file has complete instructions for building ACE, including how to configure it for your OS and compiler. This book's networked logging service example source and header files reside in $ACE_ROOT/examples/ C++NPv2 and are ready to build on any platforms that ACE supports. To build your own programs, the $ACE_ROOTdirectory must be added to your compiler's file embrace path. For command-line compilers, this can be done with the -Ior /Icompiler option. Graphical IDEs provide similar options, such as MSVC++'s "Preprocessor, Additional embrace directories" section of the C/C++ tab on the Project Settings dialog box.
