IBM IBM WebSphere Application Server

IBM claims WebSphere 5.0 presents 'genuine' internet services integration | killexams.com true Questions and Pass4sure dumps

IBM used its DeveloperWorks live convention in San Francisco to publish the impending availability of the latest version of its application server. It claims WebSphere 5.0 is the first within the trade to present "true" compliance with emerging web features requirements, proposing seamless manner-level integration between J2EE and Microsoft .web environments. huge Blue furthermore introduced a raft of tweaks and improvements to different products in its ever-widening WebSphere middleware and integration solid.

Context: concomitant records puts IBM both on degree footing or just forward of its chief emulate BEA systems within the Java-based mostly utility server space, giving both corporations about a 3rd of the market each and every -- even though massive Blue claims its commerce is growing sooner than BEA's.

while the starting to breathe maturity of the software server market is prompting some to remark that the primary players fill extra or less reached functional parity with their products, IBM says its latest efforts display it's forward of the expertise curve. The expertise component is simply section of the benchmark value proposition, but IBM believes it newest raft of updates will proceed to apply the drive on its main rivals.

software server and integration technologies may additionally solve different complications, however IBM claims its differentiator is the convergence of both applied sciences, with the software server as the underlying "engine." therefore the rebranding of IBM's integration middleware below the WebSphere banner, which now comprises MQ collection and the enterprise system integration know-how it bought from CrossWorlds.

points: WebSphere version 5.0 is with beta purchasers now and may start shipping flawless the artery through the third quarter. Key updates encompass complete compliance with J2EE 1.3, the newest spec to emerge from the Java group, in addition to "superior" web capabilities capabilities.

although IBM claimed WebSphere 4.0 was the trade's first app server to aid web features requirements similar to XML, soap, WSDL and UDDI (which BEA would strongly contest), V5 incorporates whatever thing IBM calls dynamic application interaction.

whereas net capabilities-primarily based purposes are developed using standards comparable to WSDL or soap, the interaction of these functions at a manner or workflow flat is in reality written expressly for both the .net or the J2EE ambiance, IBM argues. formerly, this required further coding to permit internet functions to exist in actually heterogeneous environments. IBM says WebSphere V5 is the primary software server to bridge this automatically.

It does this through improved integration between Java Message provider (JMS) and enterprise JavaBean (EJB) environments, which address the interactions amongst J2EE add-ons and other messaging methods, including these written for .internet. in conjunction with advanced J2EE Connector structure (JCA) guide, this has the net repercussion of enabling builders to expose J2EE and .net-primarily based purposes and web features as reusable services, that could in eddy expose application flows as a web carrier. additionally, commerce Rule Beans enable enterprise analysts to update enterprise suggestions while not having at hand-code application adjustments.

"purchasers are starting to set up net functions, but they enact not wish to upshot a J2EE or .web resolution," says Ed Harbour, director of WebSphere Commerce at IBM. IBM says it is the only vendor that has publicly announced such a means.

In tune with IBM's dedication to pass-pollinate applied sciences in its middleware portfolio, V5 comes bundled with website performance administration, authentication and access manage application from Tivoli.

Product strategy: IBM furthermore released unique and rebundled types of its integration application that are designed to simplify the pricing and packaging structure and form a springboard for drawing close 'verticalized' releases.

New applied sciences involve the WebSphere MQ suffer broking service, an extension to IBM's message queuing household that makes it possible for organizations to 'multicast' pleasing information to subscribers in response to their individual preferences. IBM claims its potential to submit this suggestions across public networks is enjoyable, although it admits different multicasting products reminiscent of Tibco's application from Talarian are largely similar.

IBM has additionally rebundled MQ and CrossWorlds capabilities to target essentially the most complicated environments organize in gargantuan corporations. WebSphere enterprise Integration 4.1 focuses on automating commerce methods, human intervention projects and information transformation and routing, and as such is an amalgam of applied sciences in the past commonplace as the CrossWorlds InterChange Server, MQ Integrator broker and MQ Workflow.

the executive section is IBM CrossWorlds four.1, which consists of a collection of procedure-degree connectors for web capabilities and monetary tips change, as well as extenders for Siebel's software network. IBM will proceed to repurpose this technology for different upright markets, together with retail distribution, telecom, car, electronics and insurance, birth in Q3. it is going to furthermore release a revamped set of B2B connectors in June, centered at inter-enterprise enterprise process integration using internet capabilities and different transport protocols.

Conclusion: youngsters customers should select it as a on the grounds that IBM integration technologies will continue to conform, the announcements this week sharpen IBM's message of being capable of remedy enterprise-driven integration issues through a series of chew-sized modules designed mainly for a number upright industries. The deliverables fill yet to arrive, however IBM says flawless the fundamental ISV partnerships are in Place for a launch within the next month or so.

Is it time to breathe terrified of IBM again? | killexams.com true Questions and Pass4sure dumps

On the mug of it the query would gawk obviously amenable to the adage that for any headline with a question mark in it the reply is no. but a few months in the past at a conference i used to breathe speaking to someone steeped in the world of open supply standardisation, having been section of the Node.js ecosystem for years and he mentioned:

“For the primary time in an extended long term i'm petrified of IBM.”

For these of you too younger to breathe aware the olden days IBM became the Google of its day, the Microsoft of its day, the AWS of its day.  because the announcing went: “IBM isn’t the competitors, it’s the ambiance wherein you compete.” IBM was completely preeminent in statistics middle computing over a *long* length of time, unless a composite of antitrust legislation, trade structural alterations, and administration errors compelled the enterprise on to the returned foot. The tenure of Louis Gerstner on the helm of IBM become slightly like Satya Nadella’s flip at Microsoft – with a renaissance in line with open standards, open supply, and being a very advantageous group associate.  by the point I entered the trade IBM became nonetheless a powerful player, but no longer the monster of historical. It nonetheless had astronomical influence over enterprise determination making. If IBM spoke of a know-how became competent for the commercial enterprise then by means of definition it become. IBM made Java an commercial enterprise typical. IBM made Linux an enterprise typical. IBM made open source a realistic commerce determination. IBM didn’t simply motivate valued clientele to adopt these applied sciences however – it demanded impact, a seat on the requirements-setting desk, with the aid of contributing developer hours, cash, and fill an repercussion on. The Apache application foundation. The Eclipse foundation. Latterly the Linux foundation. IBM did more than anyone to establish open supply implementation as the unique vogue of industry standards surroundings. IBM’s fill an upshot on remains very large in flawless of those open supply foundations, placing its weight in the back of the Linux basis’s evolution to furthermore maneuver the Node.js foundation and The Cloud endemic Computing basis.

So perquisite here they are in 2019, IBM soundless has that seat on the desk, and now it’s acquiring pink Hat, which additionally had a large footprint in these communities. The deal to buy red Hat is precisely what made the grownup above afraid. Java, Linux, Node.js and Kubernetes – IBM has a robust play in flawless of those communities. while Java and Linux are very a lot mature commodity applied sciences, Node continues to breathe setting up itself as an trade normal. commercial enterprise adoption of Kubernetes, and linked utility projects equivalent to Prometheus and Grafana, in the meantime, goes to contour the commerce over the following few years. IBM + red Hat is an extremely potent fill an upshot on bloc.

my very own select is that, principally as many within the industrial open supply supplier space fright the role of net infrastructure groups, specially Amazon net features, the influence of IBM should doubtless breathe welcomed. recently at IBM’s feel adventure my colleague Stephen O’Grady seemed on stage with IBM CEO and Chairman Ginny Rometty speakme about the ongoing vital of open source to IBM and the trade. The red Hat deal is profession defining for her, and will actually breathe hugely influential in industry instructions for the close future. discern the chart above from a submit by using Tomasz Tunguz at Redpoint Ventures for a sense of the size of wager being made perquisite here. As Tunguz argues:

pink Hat offers three businesses of application items: operating tackle (Linux and virtualization); utility construction (application server/JBoss); unique Infrastructure (OpenShift, OpenStack and Ansible). salary contribution across these categories is sixty four%, 23% and 13%. The core infrastructure (working gadget and app development) are actually super businesses, transforming into between 10-25% annually. the brand unique Infrastructure is the quickest becoming, doubling 12 months over yr.

I esteem purple Hat’s OpenShift platform because the leader in commerce platform-as-a-provider. OpenShift gives a modern building environment for software engineers. OpenShift simplifies the deployment and administration of knotty technologies like Kubernetes for significant firms.

So IBM has a pretty advantageous shielding/self-cannibalisation possibility around Websphere, a extend company in Linux, however the precise kicker for boom is red Hat OpenShift, as they tide into what I even fill relate as a secular shift around Kubernetes. actually each enterprise they talk is asking at Kubernetes as the groundwork for a huge infrastructure overhaul – each person runs K8s or is going to. Google remains the most vital contributor to Kubernetes, however red Hat has finished more than any one else to even the weight.

So enact individuals fill intent to breathe anxious? i'm relatively assured in the management of IBM individuals like Todd Moore, VP of Open technology, and their talent to enact the usurp thing for the commerce as a whole, nevertheless it became nevertheless in fact involving to listen to someone from the trade content they fill been now fearful of IBM, on account of its dominance in a yoke of vital trade necessities. It’s been a long time in view that that became the case.

additional analyzing – my boy Stephen wrote a really extraordinary publish in regards to the IBM pink Hat consolidation play.

full disclosure: AWS, IBM, crimson Hat, Microsoft and Google are flawless purchasers.

A Product Overview of DB2 9 for Linux, UNIX, and Windows | killexams.com true questions and Pass4sure dumps

This chapter is from the engage 

DB2 provides a variety of options for connecting to other DB2 and non-DB2 data servers:

  • DB2 Clients—DB2 client code is required on workstations for remote users to access a DB2 database.
  • DB2 Drivers—Some APIs that are section of a DB2 client are packaged on their own, outside of a client installation. DB2 drivers offer a more lightweight deployment option for specific API connectivity.
  • DB2 Connect™—This add-on product provides champion for applications executing on Linux, UNIX, and Windows to transparently access DB2 data servers on i5/OS, VM/VSE, and z/OS environments. DB2 Connect provides much more than just connectivity; more details of its capabilities are provided later in this chapter.

  • DB2 Replication—This feature provides replication capabilities for DB2 data servers. There are two kinds of replication, SQL-based replication and Queue-based replication (also know as Q-replication). Both are sometimes referred to as Data Propagator (DPROPR).

    SQL-based replication is included in flawless of the DB2 mainstream editions that elope on Linux, UNIX, and Windows. It's made up of two components, CAPTURE and APPLY. It uses SQL to replay data on target servers.

In DB2 9 there are basically two types of clients, the DB2 Runtime Client and the DB2 Client.

    A DB2 Runtime Client provides the minimum client footprint (about 20–30 MB) to champion connectivity to DB2 9 data servers (the exception to this is if you select to champion communication via specific API drivers, covered later in this section). When you install a DB2 Runtime Client, you install a driver to champion flawless the common programming methodologies, including ADO.NET, ADO, OLE DB, ODBC, JDBC, SQLJ, static SQL, and more.

    Using a DB2 Runtime Client you can fulfill basic functions, such as running any DB2 commands or SQL statements from a DB2 CLP or CLP session; however, for the most part, this client comes with no other capabilities than supporting data connectivity. For example, there are no graphical-based management tools, documentation, and so on. You can download a DB2 Runtime Client at www14.software.ibm.com/webapp/iwm/web/preLogin.do?lang=en_US&source=swg-dm-db2rtcl.

    A special DB2 Runtime Client is made available as Windows Merge Modules (.msi files), which makes the installation of this software within Windows applications more natural. You can download these files at http://www-304.ibm.com/jct03002c/software/data/db2/runtime.html.

    In contrast, the DB2 Client includes flawless the functions organize in the DB2 Runtime Client plus functions for client-server configuration, tools for database administration and application development, samples, and more. For example, this client includes the Configuration assistant that provides graphically administration and connectivity tools, as well as a host of programming samples, and so on. The DB2 9 Client replaces the functions organize in both the DB2 8 Application progress and DB2 8 Administration clients.

    A DB2 Client's footprint is directly correlated to the components you select to install and can select between 200 MB and 800 MB depending on the options you select. The process to install a DB2 Client is very similar to a DB2 data server. You can download a DB2 Client at http://www-304.ibm.com/jct03002c/software/data/db2/runtime.html.

    The option of which DB2 client to install should breathe based on the requirements of the application on the client machine. For example, if you fill a database application developed for Linux, UNIX, or Windows and you enact not require the DB2 administration or application progress tools from a Windows workstation, yet want to champion applications written in multiple programming languages like .NET and Java, you should install the DB2 Runtime Client on that workstation.

    Some enterprises prefer to deploy the DB2 Runtime Client code remotely on a dedicated server. In these environments, remote workstations necessity to access the DB2 Runtime Client code remotely from a code server before accessing to DB2. This character of configuration is known as a thin client. A thin-client configuration can provide many benefits, such as a central catalog directory of flawless database connections and a separate footprint of code to manage. The trade-off is that clients must load the client .dlls from the code server before accessing the remote data server. It should breathe notable however that this performance hit is only "noticed" on the initial connection. Once the client code is loaded on the client workstation, subsequent calls to the code server are not needed.

    When you want to deploy your DB2 application, you only necessity to ensure that a DB2 Runtime Client is installed on each workstation executing the application. design 1-10 shows the relationship between an application, a DB2 Runtime Client, and the DB2 data server. If the application and database are installed on the selfsame server, connectivity is considered to approach from a local client. If the application is installed on a system other than the DB2 data server, its connectivity is considered to approach from a remote client.

    Figure 1-10

    Figure 1-10 Accessing a DB2 data server using the DB2 Runtime Client

    DB2 client connectivity can breathe configured using various supported communication protocols. The supported protocols vary according to operating system:

  • TCP/IP—used in flawless environments
  • Named Pipe—used in Windows environments
  • DB2 Drivers

    Some larger enterprises and independent software vendors (ISVs) want to deploy their applications written in separate language without the overheard of installing and maintaining a DB2 client on each client workstation. Despite the much smaller footprint of the DB2 Runtime Client in DB2 9, IBM makes available two drivers that can breathe deployed for connectivity on their own, outside of a DB2 Runtime Client or DB2 Client installation.

    The IBM Driver for JDBC and SQLJ can breathe deployed to champion Java-based connectivity to a DB2 data server. This driver is about 2 MB in size and can easily breathe embedded within your application. In fact, it comes with a royalty-free distribution license for this very purpose.

    You should note however that although this driver can connect to the entire DB2 family, if you're connecting to a DB2 for i5/OS, DB2 for VM/VSE, or DB2 for z/OS data server, you necessity to additionally license this connectivity with DB2 Connect (covered in the next section) to ensure you are compliant with respect to licensing.

    It's vital to note that the IBM Driver for JDBC and SQLJ solely supports Java applications. Aside from not including tooling and documentation, this driver doesn't champion data server connectivity using other APIs. For example, you can't champion a .NET application using this driver. You can download this driver at www14.software.ibm.com/webapp/download/preconfig.jsp?id=2004-09-20+10%3A09%3A21.003415R&cat=database&fam=&s=c&S_TACT=105AGX11&S_CMP=DB2.

    DB2 9 includes a unique standalone driver for CLI and ODBC applications called the IBM DB2 Driver for ODBC and CLI. This driver delivers the selfsame benefits and restrictions as the IBM Driver for JDBC and SQLJ to your DB2 environment, except it solely supports CLI/ODBC connections. You can download this driver at www14.software.ibm.com/webapp/download/preconfig.jsp?id=2004-09-20+13%3A44%3A48.813589R&cat=database&fam=&s=c&S_TACT=105AGX11&S_CMP=SPLT.

    The main benefits of the IBM DB2 Driver for ODBC and CLI are:

  • Light-weight deployment solution for ODBC/CLI applications
  • Much smaller footprint (25M installed) than DB2 RTCL and DB2 Client
  • No necessity to fill DB2 RTCL or DB2 Client installed on the client machines
  • Same concept as the JDBC/SQLJ driver but for ODBC/CLI applications
  • DB2 Connect

    DB2 Connect is a sunder product family that licenses client connectivity from distributed platforms to the DB2 family running on i5/OS, VM/VSE, and z/OS operating systems (hereafter referred to as mainframe). Although communications between any members of the DB2 family exhaust the Distributed Relational Database Architecture (DRDA), you fill to explicitly license access from DB2 for Linux, UNIX, and Windows clients to these data servers.

    A client accessing DB2 running on the mainframe is generally referred to as a DRDA Application Requester (DRDA AR) and the DB2 server that manages the client connection as a DRDA Application Server (DRDA AS). DB2 Connect only uses TCP/IP as the transport protocol between a DRDA AR and DRDA AS.

    Some of the major capabilities provided by DB2 Connect include:

  • Support for programming APIs such as ADO, ODBC, OLE DB, CLI, JDBC, SQLJ, ADO.NET (and more) to DB2 running on the mainframe.
  • Federation across the DB2 and Informix data servers. You can extend the gain of this federation capability to heterogeneous sources by adding either WebSphere Federation Server or WebSphere Information Server.
  • Connection pooling and the more powerful connection concentration services that provide minimal resource consumption on the mainframe.
  • System z Sysplex exploitation for failover and load balancing. For example, DB2 Connect includes high-availability features such as z/OS Workload Manager Integration (WLM) and automatic re-direct to a data-sharing group.
  • Integration into mainstream progress environments for mainframe data access. For example, DB2 Connect makes data artifacts on the mainframe (including nonrelational-related services like CICS and VSAM) transparent to the world's most favorite IDEs; for example, a .NET developer can exhaust Microsoft Visual Studio 2005 and build stored procedures without knowing where the data actually resides.
  • DB2 Connect is often used to enable mainframe resources for Web access, better integrate legacy and legacy systems with unique deployments on distributed platforms, modernize the application progress suffer for mainframe progress (for example, touching from COBOL to Java), and off-loading progress cycles to lower-cost operational environments.

    Depending on the DB2 Connect edition you purchase, you can create a connectivity architecture for single- or multi-tier environments.

    You can discern in design 1-11 that there are many ways to implement a DB2 Connect product. In a multi-tier environment, you exhaust DB2 client software to connect to the DB2 Connect gateway (in a client/server model) passing the connection context to to the mainframe resource. In a Web-based deployment, you may fill DB2 Connect on its own or collocated with the application server. Depending on your configuration, you may or may not necessity to install a DB2 client.

    Figure 1-11

    Figure 1-11 Using DB2 Connect is a single-tier or multi-tier environment

    DB2 Connect products can breathe added on to an existing DB2 data server installation, or act as a standalone gateway. Either way, it's purchased separately from DB2. If you are using one of drivers discussed earlier in this chapter, technically you can upshot the connection to a mainframe DB2 resource, but you soundless necessity to purchase a sound DB2 Connect license. There are a number of DB2 Connect editions available and each is suited for a particular implementation of the DB2 Connect software. With the exception of DB2 Connect PE, flawless of the DB2 Connect editions offer the selfsame duty and features; they are merely differentiated by capability. flawless editions of DB2 Connect PE are considered gateways since they provide client/server access to workstations. To connect to a DB2 Connect gateway, you simply exhaust a DB2 client.

    DB2 Connect Personal Edition (DB2 Connect PE) is similar to DB2 Personal Edition in that it is used for separate workstations and doesn't provide its users with any server capabilities. Using DB2 Connect PE, you can upshot direct connections to DB2 running on the mainframe. In design 1-11, the desktop users likely fill DB2 Connect PE installed in their workstations. DB2 Connect PE can furthermore act as a regular DB2 client and connect to distributed versions of the data server as well. Some environments deploy DB2 Connect with both direct and gateway connectivity. For example, a developer may upshot direct connections using the DB2 Connect PE software for certain stages of the progress cycle. But once the application is in production, they may exhaust the DB2 Connect PE software to connect to a DB2 Connect gateway to select handicap of the features it provides, such as load balancing, connection optimization, high-availability, and more. DB2 Connect PE is licensed on a per-workstation basis.

    DB2 Connect Enterprise Edition (DB2 Connect EE) can breathe licensed using two different user-based options: the number of Authorized Users or the number of Concurrent Users. DB2 Connect EE provides the talent to implement a three-tier connectivity architecture that allows you to sequester connectivity to mainframe resources to a specific tier in your architecture. Again, DB2 clients (or drivers) are used to connect to the gateways, and then the DB2 Connect software manages the connection context to the mainframe.

    DB2 Connect Application Server Edition (DB2 Connect ASE) is licensed by the total VU rating of flawless the applications servers that connect to the mainframe. The VUs that you purchase fill nothing to enact with how many DB2 Connect servers you set up, or what their rating is. For example, if your Web server farm was rated at 1,000 VUs and you set up a DB2 Connect gateway farm rated at 5,000 VUs, you would fill to buy 1,000 VUs of DB2 Connect ASE. DB2 Connect ASE is well suited for environments where you expect to discern more growth of mainframe resource than your Web tier because its costs are directly linked to the VU rating of the Web serving tier.

    DB2 Connect Unlimited Edition (DB2 Connect UE) is available for i5/OS and z/OS. DB2 Connect UE for i5/OS is licensed by the number of managed processors attached to the i5/OS partition while DB2 Connect UE for z/OS is licensed with a base server license plus a per-unit saturate for the MSU rating of the System z server you are connecting to. DB2 Connect UE is well suited for environments that fill flat mainframe cycle growth and ponderous Web tier growth as the costs of DB2 Connect UE are directly correlated with the capacity of the mainframe resource. DB2 Connect UE comes with a free copy of Mobility on exact to journey mainframe data to occasionally connected devices, as well as DB2 Connect PE. Essentially, this edition of DB2 Connect, as its title would imply, allows for unlimited deployments.

    There's so much more to the DB2 Connect product than what's particular in this section. In fact, the title DB2 Connect is misleading because connectivity is just a wee section of what this product can do; however, these details are outside the scope of this book.

    DB2 Replication

    DB2 Replication allows for data to breathe propagated from one location to another. SQL-based replication, furthermore know as Data Propagator (DPROPR) replication, is a free component of the DB2 for Linux, UNIX, and Windows data servers (it's a paid feature on the mainframe). You can furthermore extend this replication capability to champion a wide variety of data servers, including DB2, Oracle, Microsoft, Sybase, Informix, IMS, Lotus Notes, and flat files with WebSphere Replication Server.

    An case of SQL-based replication is shown in design 1-12. SQL-based replication has been around for over a decade and has proven itself to breathe extremely flexible, resilient, simple to set up, and scalable.

    Figure 1-12

    Figure 1-12 SQL-based replication extended with WebSphere Replication Server

    In design 1-12 you can discern the broad gain of the SQL-based replication technology when it is extended with the WebSphere Replication Server product. As you may recall, distributed versions of DB2 approach with the DPROPR technology built in and can champion replication subscriptions across the DB2 family. The core capabilities of a distributed data server with respect to replication are shown in the top-left and top-right portions of design 1-12.

    When you buy WebSphere Replication Server, you furthermore regain Q-based replication (Figure 1-13). In Q-based replication, each message represents a transaction that is placed on a WebSphere MQ series message queue. This replication is known for its highly parallel apply process and wealthy contest detection and resolution services.

    WebSphere Federation Server and WebSphere Information Server

    WebSphere Information Server provides features and functions to place, publish, integrate, find, cleanse, and access data. The federation capabilities are worth mentioning as they relate to data access. WebSphere Federation Server contains a subset of the functionality organize in WebSphere Information Server, namely the federation capabilities (and hence will breathe the focus of this section). You can learn more about WebSphere Federation Server and WebSphere Information Server at www.ibm.com/software/data/integration/.

    A federated system is a distributed database environment that appears as a separate virtual database to cessation users and applications. The WebSphere Federation Server technology (some of which is built into DB2) allows SQL statements to transparently access, join, or update data located across heterogeneous data sources. Federated champion enables the DB2 data server to evaluate global statistics on flawless data sources in order to optimize requests for the remote data. For example, the global optimizer can exhaust erudition of source statistics, source indexes, source functions, server and network speeds, and so on.

    The SQL champion in a DB2 federated environment supports the selfsame SQL as a non-federated environment, including advanced object-relational SQL operations across the federated data sources, such as recursive SQL, common table expressions (CTEs), and more. If the remote data source doesn't fill this capability, DB2 will compensate for the missing functions.

    Perhaps the greatest capitalize to a federated system is that developers only fill to learn a separate argot of SQL; namely, the DB2 ANSI-compliant SQL API. If an external data source has different data types or non-standard SQL, DB2 will transparently compensate for missing functions and metamorphose data types. For example, SQL Server 2005 has a MONEY data character whereas DB2 uses a DECIMAL data character to champion currency. Without the WebSphere Federation Server technology, a developer would fill to know the differences between these data servers, or cast them to like data types using OLE DB. With WebSphere Federation Server, developers just code as if they were always accessing DB2 data, and the relaxation is taken custody of.

    An case of federated access is shown in design 1-14.

    Figure 1-14

    Figure 1-14 The power of federation—any data, one API

    In design 1-15 you can discern the technology components that upshot up a federated database. Nicknames are used to implement a low form of granularity with respect to the data sources you want to upshot available. Nicknames essentially are local aliases on remote tables, although they can breathe mapped to specific rows and columns. A collection of nicknames is located within a server that represents that actual data source. For example, in design 1-15 Oracle is one such data source, so the server component would picture a specific Oracle database. flawless the SQL eventually flows through a wrapper, which is a library of code that allows access to a particular class of data servers. Connections made to these servers exhaust their endemic protocol; for example, the Oracle connection will exhaust the Net8 client.

    You can discern in design 1-14 that with WebSphere Federation Server you can pretty much extend the gain of DB2 to any data source in your environment. For example, in the life sciences industry, scientists necessity access to specialized data to champion their research related to drug discovery. IBM offers a set of Life Sciences wrappers that can breathe used to build a federated system that can access data useful to scientists, including exceed spreadsheets, image data, flat files, and blast (Basic Local Alignment Search Tool).

    If a wrapper is not available for purchase, there is a software developer's kit (SDK) that you can exhaust to build your own.

    Database Enterprise Developer's Edition

    IBM offers a special discounted suite of Information Management products that you can purchase at a discount for development, evaluation, demonstration, and testing of your application programs; this edition is called Data Enterprise Developer Edition (DEDE).

    Some of the products included in this comprehensive developer offering are:

  • DB2 Express 9
  • DB2 Workgroup 9
  • DB2 Enterprise 9

  • All the DB2 Extenders™, namely DB2 Spatial Extender, DB2 Geodetic Extender, DB2 Net Search Extender, and the DB2 XML Extender
  • All of the DB2 add-on feature packs outlined earlier in this chapter
  • Most of the products within DEDE are available for flawless the platforms that DB2 Enterprise supports (unless of course a product doesn't exist on a specific platform). The data server where you install DEDE can breathe on a platform that is different from the one on which the application will eventually breathe deployed or tested because of the common code base used in the distributed DB2 environment. In fact, almost any applications developed using DEDE can breathe executed on any system that has DB2 client software (or specific drivers for which the application is written) installed.

    The application progress environment provided with DEDE allows application developers to write programs using today's most favorite methodologies, including:

  • Embedded SQL
  • Call flat Interface (CLI)/Open Database Connectivity (ODBC)

  • DEDE furthermore includes the necessary programming libraries, header files, code samples, and pre-compilers for flawless of the supported programming languages.

    DB2 Developer Workbench

    The DB2 9 Developer Workbench (DB2 DWB) replaces the DB2 8 progress Center. The DB2 DWB is an Eclipse-based graphical environment that supports the rapid progress of DB2 SQL and Java stored procedures, SQL scalar and table user defined functions (UDFs), SQL statements, XQuery statements, and Web Services. However, there's so much more to this list. For example, the DB2 DWB includes an SQL editor that's enriched with syntax colorization and code assistants, as well as teaming support, compare utilities, and more.

    The DB2 DWB is a sunder implement and is maintained sunder from a DB2 data server. You can download it from www-304.ibm.com/jct03001c/software/data/db2/ad/dwb.html.

    The DB2 DWB is really meant for power DBAs that aren't coding experts but require rapid progress assistance for building commerce logic for their data servers. Depending on your environment, you may elect to exhaust another implement like Toad for DB2 or Visual Studio. pure developers will likely select to exhaust the plug-ins provided with DB2 9 into their respective IDEs, although they are free to exhaust the DB2 DWB. For the most part, you can fulfill the selfsame tasks in any of the tools that IBM ships or the integration points in specific IDEs.

    A snapshot of the Developer Workbench screen is shown in design 1-16.

    DB2 Extenders

    DB2 Extenders offer the talent to maneuver data outside of conventional rows and columns to involve the manipulation of special data types (for example, spatial types that fill associated LAT/LONG coordinates and SQL-based functions to operate on them), searching services, and more. The purpose of the DB2 Extenders is to provide for the management of this data through the familiar DB2 SQL API.

    The DB2 Extenders encapsulate the attributes, structure, and conduct of these unstructured data types and stores this information in DB2. From the developer's perspective, the DB2 Extenders appear as seamless extensions to the database and enable the progress of multimedia-based applications. In other words, a spatial data character is no different than a built-in data character that they may breathe accustomed to. This section briefly details the DB2 Extenders that are provided by IBM.

    DB2 Spatial Extender

    The DB2 Spatial Extender (DB2 SE) provides the talent to create spatially aware data objects and store them within your DB2 database, along with other spatially related objects like (LAT/LONG) coordinates and more. Almost flawless industries could capitalize from this free technology in DB2. For example, the banking and finance industry could visually envelope customer segments for brand location identification. Municipal governments could exhaust this technology for flood unpretentious identification, the retail industry for billboard locations, and more. This seems apparent when you consider that almost flawless data has some sort of spatial component to it: they flawless fill an address, merchandise in a warehouse has a stock location, and so on.

    The commerce capitalize of the DB2 SE lies in the notion that it's a lot easier to spot visually represented information than data reported in rows and columns.

    When you enable your DB2 database for the DB2 SE, you can interact with your data using SQL or specialized spatial tools from other vendors. The point is that with the DB2 SE, DB2 understands the spatial "dialect" and the operations that you want to fulfill with it.

    For example, a telematics application on a PDA may provide its users with a list of nearby Chinese restaurants that serve Peking Duck based on the dynamic request of this user. In this case, after the client's PDA creates a location box using Global Positioning System (GPS) coordinates, it could generate SQL statements similar to the following:

    SELECT NAME, DESCRIPTION, ADDRESS FROM RESTAURANTS WHERE OVERLAPS (LOCATION, BOX(GETGPS(),2000,2000)) AND CATEGORY = 'CHINESE' AND DOC CONTAINS(MENU,'PEKING DUCK');

    OVERLAPS is a spatial duty that shows interested data in a binding box defined by the OVERLAPS border specification; there are many other spatial functions, including INTERSECTS, WITHIN, BUFFERS, and so on.

    DB2 Geodetic Extender

    The DB2 Geodetic Extender builds upon capabilities available in the DB2 Spatial Extender and adds compensation for real-world objects like the curvature of the earth's surface. The algorithms in this extender seek to remove the inaccuracies introduced by projections and so on. This extender is available only for DB2 Enterprise as section of the Data Geodetic Management feature.

    DB2 Net Search Extender

    The DB2 Net Search Extender (DB2 NSE) combines in-memory database technology with text search semantics for high-speed text search in DB2 databases. Searching with it can breathe particularly advantageous in Internet applications where performance is an vital factor. The DB2 NSE can add the power of rapidly full-text retrieval to your DB2 applications. Its features let you store unstructured text documents of up to 2 GB in databases. It offers application developers a fast, versatile, and smart routine of searching through such documents.

    Additionally, the DB2 NSE provides a wealthy set of XML searching capabilities with advanced search features like sounds-like, stemming, and so on. It is shipped free in DB2 9 (it was a chargeable extender in DB2 8) to facilitate non-XML index searching of XML data stored in pureXML columns.

    DB2 XML Extender

    The DB2 XML Extender is provided with DB2 and allows you to store XML documents in DB2; it furthermore gives you the talent to shred and store XML in its component parts as columns in multiple tables. In either case, indexes can breathe defined over the elements or attributes of an XML document for rapidly retrieval. Furthermore, text and fragment search can breathe enabled on the XML column or its decomposed parts via the DB2 Net Search Extender. The DB2 XML Extender can furthermore abet you formulate an XML document from existing DB2 tables for data interchange in business-to-business environments.

    You may recall that the pureXML add-on feature pack is available for flawless DB2 9 data servers. Indeed, this can cause confusion since the DB2 XML Extender is shipped for free in DB2 9. You should consider the DB2 XML Extender as stabilized technology. In other words, it is no longer being enhanced and shouldn't breathe considered for most XML applications. The DB2 XML Extender's approach to storing XML is to shred the XML to relational tables or stuff it into a large object. When you exhaust this technology to persist XML data, you fill to upshot grave trade-offs with respect to performance, flexibility, and so on. In addition, you fill to exhaust specialized functions to implement Spathe searches, and data types are distraught from base DB2 data types. Quite simply, the artery you interact with the DB2 XML Extender isn't natural for XML programmers and DBAs alike.

    In contrast, the pureXML feature in DB2 9 provides services such that no compromises between flexibility (what XML was designed for) and performance (one of the reasons why you want the data server to store your XML) necessity to breathe made when storing your XML data. For example, to generate XML documents from relational tables, you simple exhaust the SQL/XML API instead of the cumbersome DB2 XML Extender functions. You can validate XML documents against Sods instead of only document character definitions (Ds) as is the case with the DB2 XML Extender, and more. They strongly recommend this feature for most of your XML-based applications.


    It’s the mainframe’s eddy to regain the services treatment | killexams.com true questions and Pass4sure dumps

    In-Depth

    It’s the mainframe’s eddy to regain the services treatment
  • By Deborah Melewski
  • 10/30/2003
  • While the software industry focused on Java, .NET and Web services in recent years, the mainframe became an afterthought. It was expected to travel away.

    But IT shops are now waking up to find that the mainframe soundless runs the key enterprise applications, and that the mainframe latitude is due for some “home improvement.”

    Application progress managers are discovering that, when it comes to refashioning mainframe apps as Web services apps, there are many different ways to go. And as Gartner Inc.’s Dale Vecchio said, they may open up a Pandora’s box if the dig too deeply into that legacy code. Developers necessity to let more -- not fewer -- users into the mainframe world, and some will opt for host-to-Web, GUI extensions and screen-scrapers as the best means to start to bring the mainframe into the realm of Web services.

    When the Minnesota Dept. of Public Safety Driver and Vehicle Services (DVS) Division in St. Paul decided to integrate its legacy mainframe applications with Web services, the division chose to travel with the Verastream Host Integrator product from WRQ Inc., Seattle.

    According to Judith Franklin, manager of enterprise technology champion at DVS, the division’s goal was to help data property and accuracy, as well as turnaround time to commerce partners and the drivers of Minnesota. Challenges were plentiful. To initiate with, the system in exhaust was a largely paper-driven environment, based on a mainframe that was more than 25 years old.

    When Franklin was brought in, processing a motor vehicle title transfer took between three and six months. It was not uncommon for the processing of a driver’s license to select up to six weeks. Most of the delay, she said, was caused by the amount of time it took for the paperwork to arrive at the DVS and breathe entered. In addition, there were a lot of data-entry errors.

    “Based on their commerce model, if you needed to regain a driver’s license or renewal, or register a vehicle or transfer a title, you had to travel to their commerce partners who could breathe the cities, counties or private individuals in commerce for themselves,” said Franklin. “You would travel there, enact your paperwork and they in eddy would send us the paperwork. And there it would sit, a Great pile of paperwork that would eventually trickle to the top where their data-entry people would then enter it.”

    The DVS system was running on an IBM S390 mainframe with Cincom’s proprietary Supra database, which was proving very expensive to maintain. “We needed to enact something dramatically different,” Franklin said.

    Franklin organize two or three Cobol programmers who knew the system inside and out. As is often the case with legacy systems, there was very cramped documentation. The screens were typical CICS screens, and could not breathe released to commerce partners or to the public because they contained too much information and were difficult to read.

    Franklin’s first goal was to enact something effective -- and in a relatively short timeframe -- that would allow the DVS to start publishing on the Web and provide a service-oriented approach for doing transactions and real-time data entry with commerce partners. It was not necessary to enhance the current system because the DVS planned to eventually journey away from that database.

    “We required a implement with a minimal learning curve for Visual Basic programmers already on staff, rather than having to bring in Java programmers and build up expertise,” said Franklin. “We furthermore wanted a implement springy enough to meet into wherever they would breathe doing their core application progress as they grew.”

    Using Verastream Host Integrator with Microsoft Visual Studio, and running on Microsoft IIS with ASP, the DVS went live with two Web sites for driver’s license applications in less than two months. One site was for the public, while the other was a private authenticated site for commerce partners.

    The DVS built Web apps that travel to the Verastream middleware, which then goes to the mainframe and returns data with records that are deployed and formatted for readability. The DVS is furthermore merging its Verastream model with a variety of SQL databases.

    A site for law enforcement was then added. “This has been a huge turnaround for the state,” said Franklin. “Our law-enforcement partners content that the services they now provide are the best tools they’ve been given since the mobile radio.”

    Prior to Web services, law-enforcement officials had to spread out pages of papers; with the unique system, they can access a current, readable driver’s record. More than 10 million photos can breathe stored using the SQL database, and the records are integrated with the photos.

    The division has taken data entry out to flawless deputies and agents in the state, and has been doing real-time transactions for about a year. “This has allowed us to withstand budget issues that flawless states are going through, and it has increased the accuracy of their data,” said Franklin. “The DVS has saved some $260,000 in programming/legacy storage costs, and has crop license processing times by 75%.”

    But the change was not completely smooth, admitted Franklin. The DVS went from a batch-processing concept to one that suddenly opened up 24x7. There were furthermore bandwidth problems when the DVS started getting more than 27,000 hits a day.

    “In many ways, their mainframe people weren’t prepared for the extend in production, CPU cycles and database calls, which more than doubled in the first three months after opening up their mainframe to the Web,” she said. “And they erudite that it would flawless double again during the next three months.”

    Also a concern: maintenance. DVS people brought everything down for maintenance one Saturday morning. “It was a one-time job on a Saturday morning, and suddenly the motor vehicle site is down and my beeper is going off,” said Franklin, admitting to some shortsightedness. “The concept is so different now that you might unwittingly let things like that slip by.”

    Performance is key

    “People are finding that they necessity to journey their applications to the Web to upshot it easier for their customers and partners to enact commerce with them,” said Scott Rosenbloom, chief strategist at WRQ. “One of the challenges is that some 60%–70% of their information and commerce logic is stored on legacy systems.”

    Companies necessity to journey quickly to the Web, so re-creating commerce logic and data on unique platforms is just not possible, he added. “They’re starting to step back and say, ‘We already fill that commerce logic and information. It’s reliable, and it’s been on the host maybe 15 or more years. Let’s find a artery to expose that to the Web to upshot the creation of these unique applications quicker and give them higher functionality.’”

    WRQ’s Verastream product is a runtime server with design tools. It works with products like Microsoft Visual Studio .NET, BEA Workshop and IBM’s WebSphere. “We expose the information with Verastream, and that is used to build the actual application,” said Rosenbloom.

    The WRQ tools furthermore champion setting layers of granularity. Many approaches to integration in the past failed, notable Rosenbloom, because when people started using services like CORBA they did not change the artery they viewed the calls, even though they were going over a network where there is a lot more overhead and latency.

    “In Web services, you can fill this selfsame challenge -- if you just expose the existing API via Web services, you could fill very low-level, fine-grain calls going on. For example, if you’re updating a field or a record as opposed to sending an entire document complete of many records that you may want to submit flawless at once,” Rosenbloom explained.

    “It’s very vital that you implement Web services with the perquisite flat of granularity when you upshot this Web service call because there is a lot of overhead associated with this call,” he added. “You’re creating an XML document. You’re shipping it over a protocol like HTTP over the network, and there are a lot of different things going on; you want to ensure that when you upshot that call over the network, it will enact a lot of travail for you before it returns.”
