notwithstanding SCO's UnixWare 7.1.4 helps Linux-like capabilities that enable applications to elope natively on commandeer of UnixWare, SCO engineers favourite to completely port open-supply purposes into the UnixWare environment. Doing so makes functions more without problems attainable in binary form, which could greatly ease compatibility considerations across a variety of flavors of open-source OSes. SCO's inclusion of these ported functions will support Linux developers transitioning to UnixWare. up to now, Linux clients needed to port and recompile functions manually without a live sure that a ported software would work throughout Linux adaptations.
UnixWare contains a particularly optimized C++ compiler for the Intel platform. A memory-leak device and a graphical debugger that can work with threaded applications are moreover a allotment of the OS's construction kit. UnixWare moreover comprises sun's J2SE 1.four.2, Postgres, MySQL and personal home page.
UnixWare packs powerful tools for net and web functions builders, including a soap/XML toolkit with Apache Axis, gSOAP and PEAR::soap. UnixWare's web services Substrate extends legacy eco-friendly monitor purposes to the internet or to the computing device. by using getting access to software memory and interacting directly with instructions, the substrate gear can interface with Cobol and legacy C courses that consume text-based mostly GUIs.
UnixWare's key kernel locking potential allows builders to pre-empt the kernel at any factor to elope other techniques. This granular locking mechanism allows UnixWare to guide up to 32 CPUs, the highest that can moreover live used by the Intel platform. home windows and Linux don't tender this characteristic. UnixWare's kernel technology instantly optimizes virtual reminiscence according to purchasable server memory and pressure space. This computerized tuning manner takes complete capabilities of gear elements, releasing administrators from having to tweak the OS. because many techniques these days achieve not consist of floppy drives, UnixWare helps media-less dispensed installations over a community. The server additionally includes a mass replication tool to create server images. UnixWare supports up to 64 Gbytes of RAM and file sizes as much as 1 Tbyte. The OS moreover helps scorching-swappable CPUs, Intel's hyperthreading know-how, USB 2.0 and numerous DVD drives. UnixWare is commonly utilized in POS and embedded Intel-primarily based methods, considering the fact that the OS supports javax.comm for POS functions that elope on JBoss. JBoss does not ship with UnixWare, but it surely is attainable through the Skunkware project.
SCO's Merge technology permits windows functions to elope natively in UnixWare. This capacity is chiefly crucial for groups consolidating servers, considering that Merge permits any home windows utility to elope aspect-by way of-facet with Unix apps. despite the fact, interfacing with home windows applications is proscribed to internet services or client-base communique through a network. The OS does not supply direct calls to windows applications. UnixWare purposes can best engage with .internet functions through web capabilities.
UnixWare helps many networking and protection protocols similar to VPN tunneling, autochthonous firewall skill for bidirectional traffic, PAM and NSS support, Samba and encryption for its file equipment. The server contains a GUI-based mostly administration interface, which moreover works in text-base form, allowing administrators to manage each tool and possess via a single administration interface. SCO's channel program presents an ordinary reseller margin of 25 percent. The commerce offers MDFs, product discounts and sponsorship alternatives. customized, on-website sales practising is equipped yearly on the company's annual ally conference and on the web. partners should pay for mobile technical assist at at the very least 11 hours, but discounts can live establish in line with accomplice level.

ACE is a highly portable, widely used, open-source host infrastructure middleware toolkit. The source code is freely available from http://ace.ece.uci.edu/ or http://
www.riverace.com/. The core ACE library contains roughly a quarter million lines of C++ code that comprises approximately 500 classes. Many of these classes cooperate to profile ACE's major frameworks. The ACE toolkit moreover includes higher-level components, as well as a big set of examples and an extensive automated regression test suite.
To separate concerns, reduce complexity, and permit functional subsetting, ACE is designed using a layered architecture [POSA1], shown in device 1.7. The capabilities provided by ACE span the session, presentation, and application layers in the OSI reference model [Bla91]. The foundation of the ACE toolkit is its combination of an OS adaptation layer and C++ wrapper facades, which together encapsulate core OS network programming mechanisms to elope portably on whole the OS platforms shown in Sidebar 2 (page 16). The higher layers of ACE build on this foundation to provide reusable frameworks, networked service components, and standards-based middleware.
device 1.7: The Layered Architecture of ACE1.4.2 A Synopsis of the ACE Frameworks
The ACE frameworks are an integrated set of classes that can live instantiated and customized to provide complete networked applications and service components. These frameworks aid to transfer decades of accumulated information directly from the ACE developers to
Sidebar 2: OS Platforms Supported by ACE
ACE runs on a wide sweep of operating systems, including:
PCs, for example, Windows (32- and 64-bit versions), WinCE, and Macintosh OS X
Most versions 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 operating systems, for example, VxWorks, ChorusOS, LynxOS, Phar-lap TNT, QNX Neutrino and RTP, RTEMS, and pSoS
Large enterprise systems, for example, OpenVMS, MVS OpenEdition, Tandem NonStop-UX, and Cray UNICOS.
ACE can live used with whole of the major C++ compilers on these platforms. The ACE Web site at http://ace.ece.uci.educontains a complete, up-to-date list of platforms, along with instructions for downloading and structure ACE.
ACE users in the profile of expertise embodied in well-tested and reusable C++ software 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 rely on and consume each other, the lines between boxes picture a dependency in the direction of the arrow. Each framework is outlined below.
device 1.8: The Key Frameworks in ACE
ACE Reactor and Proactor frameworks. These frameworks implement the Reactor and Proactor patterns [POSA2], respectively. Both are architectural patterns that allow applications to live driven by events that are delivered to the application from one or more event sources, the most famous of which are I/O endpoints. The Reactor framework facilitates a reactive I/O model, with events signaling the ability to commence a synchronous I/O operation. The Proactor framework is designed for a proactive I/O model where one or more asynchronous I/O operations are initiated and the completion of each operation triggers an event. Proactive I/O models can achieve the performance benefits of concurrency without incurring many of its liabilities. The Reactor and Proactor frameworks automate the detection, demultiplexing, and dispatching of application-defined handlers in response to many types of events. Chapters 3 and 4 record the ACE Reactor framework and Chapter 8 describes the ACE Proactor framework.
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 live assembled late in the design cycle, such as at installation time and/or elope time. Applications with tall availability requirements, such as mission-critical systems that accomplish online transaction processing or real-time industrial process automation, often require such resilient configuration capabilities. Chapter 2 describes the design dimensions associated with configuring networked services and Chapter 5 describes the ACE Service Configurator framework.
ACE Task framework. This framework implements various concurrency patterns, such as energetic object and Half-Sync/Half-Async [POSA2]. energetic object is a design pattern that decouples the thread that executes a system 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 book describes the ACE Task 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 energetic 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 development 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 development of networked applications that can live updated and extended without the need 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:
Inversion of Control
Reactor and Proactor
Calls back to application-supplied event handlers to accomplish processing when events occur synchronously and asynchronously.
Calls back to application-supplied service objects to initialize, suspend, resume, and finalize them.
Calls back to an application-supplied hook system to accomplish processing in one or more threads of control.
Calls back to service handlers to initialize them after they're connected.
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 consume 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 consume callbacks or virtual methods, so they aren't as extensible as the ACE frameworks. The ACE wrapper facades achieve support a broad sweep of consume cases, however, and can live 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 include lists, queues, hash tables, strings, and other reusable data structures. Likewise, application-defined code invoked by event handlers in the ACE Reactor framework can consume the ACE wrapper facades and the C++ standard 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.

Sidebar 3: structure ACE and Programs that consume ACE
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 moreover purchase a prebuilt version of ACE from Riverace at a nominal cost. contemplate 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 refer to this top-level directory as "ACE_ROOT." You should create an environment variable by that denomination containing the complete 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 structure ACE, including how to configure it for your OS and compiler. This book's networked logging service case source and header files reside in $ACE_ROOT/examples/ C++NPv2 and are ready to build on whole platforms that ACE supports. To build your own programs, the $ACE_ROOTdirectory must live added to your compiler's file include path. For command-line compilers, this can live done with the -Ior /Icompiler option. Graphical IDEs provide similar options, such as MSVC++'s "Preprocessor, Additional include directories" section of the C/C++ tab on the Project Settings dialog box.
