IBM WebSphere InterChange Server V4.3

IBM Unveils Workflow Engine for WebSphere | killexams.com Real Questions and Pass4sure dumps

IBM Unveils Workflow Engine for WebSphere

massive Blue's Domino, MQ Workflow, Crossworlds server products additionally to get new engine.

  • with the aid of Stephen Swoyer
  • 10/22/2002
  • IBM Corp. introduced ultimate week that the upcoming version 5.0 liberate of its WebSphere utility Server (turned into) will ship with a new workflow engine. additionally, an IBM spokesman established that big Blue's MQ Workflow, Crossworlds Interchange Server, and Lotus Domino products will additionally make the most the new workflow engine.

    in accordance with Shawn Willet, a principal analyst with market analysis firm latest analysis, IBM's new workflow engine solves one of large Blue's most persistent problems. in the past, Willet aspects out, IBM has maintained as many as four distinctive business procedure management (BPM)—or "workflow"—implementations across its latitude of items. "IBM has gotten loads of flack about having too many BPM items, so this rationalizes having the equal [workflow] engine with a single construction application, which is respectable."

    became 5.0 alterations all of that, based on Stefan Van Overtveldt, IBM's director of WebSphere technical marketing. "What we've got carried out now in version 5 is made [WebSphere's existing workflow implementation] into an extremely flexible workflow engine it really is focused to workflows between J2EE and web functions."

    The upshot of all of it, Van Overtveldt explains, is that changed into 5.0's workflow engine "permits you to create workflow processes between web services and expose workflow tactics as web functions."

    Van Overtveldt says that IBM will include the brand new workflow engine into future types of its MQ Workflow and Crossworlds Interchange Server equipment, however stresses "this does not mean that we're going to stop shipping these tools. in its place of their current run-time environments, they might be sitting on an embedded replica of [the workflow engine] that sits under the covers."

    big Blue has introduced that it will ship Lotus Domino R6 with a one-time license for changed into 5.0, thereby exposing the Notes/Domino environment to its new workflow engine as smartly.

    was 5.0's workflow engine boasts a technology that IBM calls "compensation." Van Overtveldt claims the expertise enables the workflow engine to get better from blunders encountered all over a workflow sequence. "From an operational standpoint, you can also have a workflow that has one sequence when you're going through it, but when you deserve to back out of it, you need to go in a special order."

    The workflow engine boasts tight integration with IBM's WebSphere Studio built-in construction ambiance. subsequently, Van Overtveldt says that users can create point-and-click workflows in WebSphere Studio. He stresses that "you will not hear me say that this is whatever thing relevant for a business supervisor. this is basically focused at knowledgeable builders." it's as a result of "whereas you could visually draw all of these objects collectively, you still deserve to have an understanding of the houses of those objects."

    Crossworlds Interchange server, then again, will use the identical workflow engine, and is "a tool it really is extra suitable for business managers," Van Overtveldt says.

    while a multi-aim workflow engine could make sense from a construction point of view, latest evaluation' Willet wonders concerning the extent to which a single workflow implementation can tackle a number of distinctive BPM necessities.

    "I do have a priority that these are basically distinct types of animals. A human workflow product is in fact a distinct animal than a workflow that a programmer would use, or the workflow used in an enterprise application integration venture," he observes. "Their challenge is to make use of the identical engine but keep the genuine interfaces fairly diverse."

    Brent Sleeper, co-founder and main with business procedure consultancy The Stencil group, agrees. "probably the most challenges of any sort of workflow or enterprise technique administration utility product is how do you are making it interoperable ample to tackle the vast majority of company strategies and functions which are accessible, with out making it so dumbed-down and simplified that the tough complications cannot be solved," he notes. "this is been a paradox that is present in any kind of software that tries to tackle this, and or not it's exacerbated with whatever thing like the [IBM] workflow engine this is relying on a comparatively standardized method of doing issues."

    Workflow normal still a No-ShowWAS 5.0's workflow engine will seem absent guide for the business procedure Execution Language for internet capabilities (BPEL4WS), a proposed regular for specifying company procedure behavior that's based on web features. The BPEL4WS specification is supported with the aid of IBM, Microsoft Corp. and BEA systems, among others, but hasn't yet been finalized.

    When BPEL4WS is launched, speculates Daniel Sholler, vice president of the application delivery recommendations service with consultancy Meta community, "the imaginative and prescient is to have a common workflow language and a standard execution ambiance to explain the language of company techniques."

    except BPEL4WS is finalized, feedback IBM's Van Overtveldt, the workflow engine will exploit a proprietary language to outline workflows. "the style we define these workflows at the moment is thru a proprietary flow language known as FDML [flow definition markup language]. we will very impulsively add assist for [BPEL4WS], as a business manner on suitable of net capabilities."

    IBM will ship a provider pack replace that contains BPEL4WS assist when the commonplace is finalized, Van Overtveldt confirms.

    For his part, Stencil group's Sleeper anticipates that the initial BPEL4WS specification will lay the groundwork for a common workflow language throughout all systems, but cautions that the common additionally runs the "risk of … trivializing the complexity of the business techniques." based on Sleeper, the version of BPEL4WS it really is expected to be approved later this yr or early subsequent year is appropriate for customary implementations but isn't yet effective sufficient to explain esoteric company processes.

    "there's lots of skills for [BPEL4WS] to assist carry workflow and assist deliver enterprise manner administration to a enhanced percentage of the issues available, [but] frankly, it's no longer going to solve the hardest problems. it will possibly aid to solve 50 to eighty p.c of the situations out there," he argues.

    IBM Acquires Sterling Commerce | killexams.com Real Questions and Pass4sure dumps

    news

    IBM Acquires Sterling Commerce

    IBM these days stated it has agreed to purchase Sterling Commerce, a business enterprise of utility that performs significant scale business-to-enterprise transactions, from AT&T for $1.4 billion.

    One most excellent called a number one issuer of electronic records interchange (EDI) utility, Dublin, Ohio-primarily based Sterling Commerce tactics giant volumes of transactions between b-to-b buying and selling companions through public and personal networks and cloud-based mostly exchanges.

    Sterling become got in 2000 via AT&T, then known as SBC Communications. however as AT&T is now focusing more on broadband communications and wireless capabilities, observers say Sterling turned into less strategic to the service.

    meanwhile, for IBM, Sterling compliments its WebSphere Commerce server portfolio. Sterling referred to it has 18,000 customers, together with colossal banks, telcos and sellers. "this is a big consumer acquisition," stated Altimeter analyst Ray Wang, in an interview. "These are typically the greatest customers which are scaling issues right here, so when you fit that into the IBM portfolio through vertical, then which you could see lots of synergies happening."

    On a conference call announcing the deal, Craig Hayman, usual supervisor of IBM software neighborhood's WebSphere enterprise, stated IBM will bring Sterling into the WebSphere suite, and layer huge Blue's suggestions management, analytics and company technique administration utility into Sterling's utility.

    "we are able to now be able to present consumers the pliability of managing their business partner networks in their own premises under ordinary commercial enterprise model or through a cloud computing start mannequin -- anything we agree with is awfully appealing to a large number of our shoppers," Hayman observed.

    IBM referred to it expects the deal to close in the 2nd half of this yr, pending regulatory approvals.

    A Product Overview of DB2 9 for Linux, UNIX, and home windows | killexams.com Real Questions and Pass4sure dumps

    This chapter is from the booklet 

    DB2 gives a variety of alternate options for connecting to different DB2 and non-DB2 statistics servers:

  • DB2 valued clientele—DB2 customer code is required on workstations for far off clients to entry a DB2 database.
  • DB2 Drivers—Some APIs which are part of a DB2 customer are packaged on their personal, outdoor of a client installation. DB2 drivers offer a greater light-weight deployment alternative for particular API connectivity.
  • DB2 connect™—This add-on product gives help for purposes executing on Linux, UNIX, and windows to transparently entry DB2 information servers on i5/OS, VM/VSE, and z/OS environments. DB2 join gives a lot more than just connectivity; extra particulars of its capabilities are provided later during this chapter.

  • DB2 Replication—This characteristic provides replication capabilities for DB2 statistics servers. There are two forms of replication, SQL-based replication and Queue-based mostly replication (also comprehend as Q-replication). each are once in a while known as statistics Propagator (DPROPR).

    SQL-based replication is protected in all of the DB2 mainstream editions that run on Linux, UNIX, and home windows. or not it's made up of two accessories, seize and follow. It makes use of SQL to replay information on track servers.

    Q-Replication is developed on the IBM WebSphere MQSeries® expertise and is commonly notion to be a extra purchasable and powerful replication technology. which you can add this means to a DB2 environment through one of the WebSphere counsel Integrator products.

  • WebSphere information Server or WebSphere Federation Server—The WebSphere manufacturer has a collection of items that assist you publish, area, cleanse, seriously change, enrich, and access information across heterogeneous records sources.
  • WebSphere utility Server—part of this software server is sent with DB2. It permits builders to make use of Java as a platform in a transaction processing ambiance.
  • DB2 clients

    as soon as a DB2 application has been developed, you should install connectivity application on each and every customer laptop in a two-tier atmosphere. if you are deploying an internet-based software in a three-tier environment, you should, at a minimal, deploy the DB2 customer connectivity utility on the software server. In DB2 9 there are definitely two forms of clients, the DB2 Runtime customer and the DB2 customer.

    A DB2 Runtime customer offers the minimal customer footprint (about 20–30 MB) to assist connectivity to DB2 9 records servers (the exception to here's if you choose to support verbal exchange by means of particular API drivers, covered later during this part). in the event you installation a DB2 Runtime customer, you set up a driver to help all of the average programming methodologies, including ADO.web, ADO, OLE DB, ODBC, JDBC, SQLJ, static SQL, and greater.

    the use of a DB2 Runtime client which you could operate basic features, corresponding to working any DB2 instructions or SQL statements from a DB2 CLP or CLP session; however, for essentially the most part, this customer comes with out a other capabilities than helping facts connectivity. as an instance, there are no graphical-based mostly administration equipment, documentation, and so forth. that you can download a DB2 Runtime client at www14.utility.ibm.com/webapp/iwm/web/preLogin.do?lang=en_US&supply=swg-dm-db2rtcl.

    a distinct DB2 Runtime customer is made obtainable as home windows Merge Modules (.msi files), which makes the installation of this application inside home windows applications extra natural. that you could download these data at http://www-304.ibm.com/jct03002c/utility/facts/db2/runtime.html.

    In distinction, the DB2 customer comprises all of the features found in the DB2 Runtime customer plus functions for client-server configuration, tools for database administration and utility construction, samples, and extra. for instance, this client includes the Configuration Assistant that offers graphically administration and connectivity tools, as well as a bunch of programming samples, etc. The DB2 9 client replaces the functions found in each the DB2 8 application development and DB2 eight Administration purchasers.

    A DB2 client's footprint is without delay correlated to the accessories you choose to installation and may take between 200 MB and 800 MB depending on the options you select. The system to installation a DB2 customer is terribly akin to a DB2 information server. you could download a DB2 client at http://www-304.ibm.com/jct03002c/application/statistics/db2/runtime.html.

    The choice of which DB2 customer to deploy should still be in line with the necessities of the software on the client machine. for instance, in case you have a database application developed for Linux, UNIX, or windows and also you do not require the DB2 administration or application construction equipment from a home windows computing device, yet want to aid functions written in assorted programming languages like .internet and Java, make sure you install the DB2 Runtime client on that laptop.

    Some enterprises opt to deploy the DB2 Runtime customer code remotely on a dedicated server. In these environments, faraway workstations need to access the DB2 Runtime customer code remotely from a code server before getting access to to DB2. This classification of configuration is known as a skinny customer. a thin-customer configuration can supply many benefits, similar to a central catalog directory of all database connections and a single footprint of code to manage. The change-off is that shoppers should load the customer .dlls from the code server earlier than getting access to the far flung facts server. it's going to be stated besides the fact that children that this performance hit is simply "observed" on the preliminary connection. once the customer code is loaded on the customer computer, subsequent calls to the code server don't seem to be needed.

    for those who need to install your DB2 application, you most effective deserve to ensure that a DB2 Runtime customer is installed on every laptop executing the application. determine 1-10 indicates the connection between an software, a DB2 Runtime client, and the DB2 information server. If the utility and database are put in on the equal server, connectivity is regarded to come back from a local client. If the application is put in on a gadget other than the DB2 records server, its connectivity is regarded to come from a remote client.

    Figure 1-10

    figure 1-10 accessing a DB2 statistics server the usage of the DB2 Runtime customer

    DB2 client connectivity may also be configured the use of a lot of supported verbal exchange protocols. The supported protocols range in line with operating system:

  • TCP/IP—used in all environments
  • Named Pipe—utilized in windows environments
  • DB2 Drivers

    Some better businesses and unbiased utility providers (ISVs) need to deploy their purposes written in single language devoid of the overheard of setting up and retaining a DB2 client on every client notebook. regardless of the a good deal smaller footprint of the DB2 Runtime customer in DB2 9, IBM makes obtainable two drivers that can be deployed for connectivity on their personal, outside of a DB2 Runtime customer or DB2 customer installation.

    The IBM Driver for JDBC and SQLJ can also be deployed to guide Java-based connectivity to a DB2 statistics server. This driver is ready 2 MB in measurement and might effortlessly be embedded inside your utility. really, it comes with a royalty-free distribution license for this very goal.

    you should definitely be aware however that although this driver can hook up with the whole DB2 family unit, if you are connecting to a DB2 for i5/OS, DB2 for VM/VSE, or DB2 for z/OS information server, you deserve to moreover license this connectivity with DB2 join (covered in the next part) to be sure you are compliant with admire to licensing.

    or not it's essential to note that the IBM Driver for JDBC and SQLJ solely supports Java applications. aside from not together with tooling and documentation, this driver doesn't aid statistics server connectivity using other APIs. as an instance, you can't guide a .net utility the usage of this driver. which you can download this driver at www14.utility.ibm.com/webapp/download/preconfig.jsp?id=2004-09-20+10p.c3A09%3A21.003415R&cat=database&fam=&s=c&S_TACT=105AGX11&S_CMP=DB2.

    DB2 9 comprises a brand new standalone driver for CLI and ODBC purposes known as the IBM DB2 Driver for ODBC and CLI. This driver grants the same merits and restrictions as the IBM Driver for JDBC and SQLJ to your DB2 environment, except it entirely supports CLI/ODBC connections. that you may download this driver at www14.software.ibm.com/webapp/download/preconfig.jsp?identification=2004-09-20+13p.c3A44p.c3A48.813589R&cat=database&fam=&s=c&S_TACT=105AGX11&S_CMP=SPLT.

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

  • easy-weight deployment solution for ODBC/CLI applications
  • much smaller footprint (25M put in) than DB2 RTCL and DB2 customer
  • No should have DB2 RTCL or DB2 customer installed on the client machines
  • equal conception because the JDBC/SQLJ driver however for ODBC/CLI functions
  • DB2 join

    DB2 join is a separate product family that licenses customer connectivity from dispensed platforms to the DB2 household operating on i5/OS, VM/VSE, and z/OS working programs (hereafter referred to as mainframe). although communications between any individuals of the DB2 family unit use the distributed Relational Database structure (DRDA), you have to explicitly license entry from DB2 for Linux, UNIX, and windows customers to these statistics servers.

    a client gaining access to DB2 operating on the mainframe is frequently called a DRDA software Requester (DRDA AR) and the DB2 server that manages the customer connection as a DRDA software Server (DRDA AS). DB2 join only makes use of TCP/IP because the transport protocol between a DRDA AR and DRDA AS.

    one of the most important capabilities provided via DB2 connect include:

  • help for programming APIs akin to ADO, ODBC, OLE DB, CLI, JDBC, SQLJ, ADO.net (and more) to DB2 operating on the mainframe.
  • Federation throughout the DB2 and Informix data servers. you could extend the attain of this federation potential to heterogeneous sources by means of adding both WebSphere Federation Server or WebSphere counsel Server.
  • Connection pooling and the greater effective connection awareness services that give minimal resource consumption on the mainframe.
  • system z Sysplex exploitation for failover and load balancing. for example, DB2 connect includes high-availability points comparable to z/OS Workload manager Integration (WLM) and computerized re-direct to a data-sharing group.
  • Integration into mainstream building environments for mainframe information entry. as an example, DB2 connect makes records artifacts on the mainframe (including nonrelational-connected services like CICS and VSAM) transparent to the area's most usual IDEs; for instance, a .net developer can use Microsoft visual Studio 2005 and build kept strategies without realizing where the information basically resides.
  • DB2 connect is often used to permit mainframe substances for web entry, improved combine legacy and heritage systems with new deployments on dispensed systems, modernize the application development event for mainframe building (for instance, moving from COBOL to Java), and off-loading construction cycles to decrease-can charge operational environments.

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

    which you can see in determine 1-11 that there are many easy methods to enforce a DB2 join product. In a multi-tier environment, you employ DB2 customer utility to connect to the DB2 join gateway (in a client/server mannequin) passing the connection context to to the mainframe useful resource. In a web-based mostly deployment, you may additionally have DB2 join by itself or collocated with the application server. counting on your configuration, you can also or may additionally now not should installation a DB2 customer.

    Figure 1-11

    determine 1-eleven the use of DB2 connect is a single-tier or multi-tier atmosphere

    DB2 join items will also be added on to an latest DB2 facts server installing, or act as a standalone gateway. both manner, it be bought one at a time from DB2. if you're the usage of considered one of drivers mentioned past in this chapter, technically you could make the connection to a mainframe DB2 useful resource, however you nonetheless deserve to purchase a valid DB2 connect license. There are a few DB2 connect versions accessible and each is proper for a specific implementation of the DB2 join application. aside from DB2 join PE, all the DB2 connect versions offer the equal feature and features; they are in simple terms differentiated by way of capability. All variations of DB2 connect PE are regarded gateways given that they provide client/server entry to workstations. To hook up with a DB2 join gateway, you readily use a DB2 client.

    DB2 connect personal version (DB2 connect PE) is akin to DB2 personal edition in that it's used for single workstations and doesn't deliver its clients with any server capabilities. the usage of DB2 connect PE, you can make direct connections to DB2 running on the mainframe. In figure 1-11, the computer users doubtless have DB2 connect PE put in in their workstations. DB2 connect PE can also act as an everyday DB2 customer and fasten to allotted versions of the facts server as smartly. Some environments install DB2 join with both direct and gateway connectivity. for example, a developer may additionally make direct connections using the DB2 connect PE utility for definite stages of the construction cycle. however as soon as the application is in construction, they may also use the DB2 connect PE application to hook up with a DB2 join gateway to take knowledge of the facets it offers, comparable to load balancing, connection optimization, high-availability, and extra. DB2 join PE is licensed on a per-pc foundation.

    DB2 join business edition (DB2 join EE) will also be licensed the usage of two distinctive user-primarily based alternate options: the number of approved users or the variety of Concurrent users. DB2 connect EE provides the capacity to put in force a 3-tier connectivity architecture that means that you can isolate connectivity to mainframe resources to a selected tier on your architecture. once again, DB2 purchasers (or drivers) are used to connect to the gateways, after which the DB2 join utility manages the connection context to the mainframe.

    DB2 join software Server edition (DB2 join ASE) is licensed through the overall VU rating of all the applications servers that hook up with the mainframe. The VUs that you just buy have nothing to do with what number of DB2 connect servers you set up, or what their score is. for instance, in case your internet server farm become rated at 1,000 VUs and also you set up a DB2 connect gateway farm rated at 5,000 VUs, you can should purchase 1,000 VUs of DB2 join ASE. DB2 connect ASE is greatest for environments the place you predict to see greater growth of mainframe resource than your internet tier as a result of its charges are at once linked to the VU ranking of the internet serving tier.

    DB2 connect unlimited version (DB2 join UE) is available for i5/OS and z/OS. DB2 join UE for i5/OS is licensed by means of the number of managed processors connected to the i5/OS partition while DB2 join UE for z/OS is licensed with a base server license plus a per-unit can charge for the MSU ranking of the device z server you're connecting to. DB2 connect UE is splendid for environments which have flat mainframe cycle increase and heavy net tier boom as the expenses of DB2 join UE are without delay correlated with the capability of the mainframe useful resource. DB2 connect UE comes with a free reproduction of Mobility on Demand to flow mainframe statistics to now and again connected gadgets, in addition to DB2 connect PE. just about, this edition of DB2 join, as its identify would imply, enables for limitless deployments.

    there's so a whole lot extra to the DB2 join product than what's targeted in this section. truly, the identify DB2 join is deceptive as a result of connectivity is just a small part of what this product can do; youngsters, these details are outside the scope of this e-book.

    DB2 Replication

    DB2 Replication allows for for records to be propagated from one vicinity to a further. SQL-primarily based replication, additionally comprehend as information Propagator (DPROPR) replication, is a free part of the DB2 for Linux, UNIX, and windows statistics servers (it be a paid function on the mainframe). that you may also prolong this replication capability to assist a large choice of data servers, including DB2, Oracle, Microsoft, Sybase, Informix, IMS, Lotus Notes, and flat files with WebSphere Replication Server.

    An illustration of SQL-primarily based replication is shown in figure 1-12. SQL-based replication has been around for over a decade and has confirmed itself to be extraordinarily bendy, resilient, convenient to install, and scalable.

    Figure 1-12

    figure 1-12 SQL-based mostly replication extended with WebSphere Replication Server

    In figure 1-12 that you would be able to see the extensive attain of the SQL-primarily based replication technology when it is extended with the WebSphere Replication Server product. As you may recall, distributed versions of DB2 include the DPROPR technology inbuilt and may assist replication subscriptions across the DB2 household. The core capabilities of a disbursed statistics server with recognize to replication are proven in the excellent-left and accurate-correct portions of determine 1-12.

    if you happen to purchase WebSphere Replication Server, you additionally get Q-based replication (determine 1-13). In Q-based mostly replication, every message represents a transaction it is placed on a WebSphere MQ series message queue. This replication is time-honored for its totally parallel follow procedure and wealthy battle detection and determination functions.

    WebSphere Federation Server and WebSphere information Server

    WebSphere suggestions Server gives aspects and services to location, post, combine, locate, cleanse, and entry information. The federation capabilities are worth citing as they relate to data access. WebSphere Federation Server incorporates a subset of the functionality present in WebSphere assistance Server, particularly the federation capabilities (and hence will be the center of attention of this part). you can gain knowledge of extra about WebSphere Federation Server and WebSphere assistance Server at www.ibm.com/software/facts/integration/.

    A federated system is a dispensed database atmosphere that appears as a single virtual database to conclusion users and applications. The WebSphere Federation Server expertise (some of which is built into DB2) permits SQL statements to transparently entry, be part of, or replace records found throughout heterogeneous information sources. Federated support allows for the DB2 information server to evaluate global facts on all statistics sources in order to optimize requests for the remote facts. as an example, the world optimizer can use knowledge of source records, source indexes, supply capabilities, server and network speeds, and so on.

    The SQL help in a DB2 federated ambiance supports the same SQL as a non-federated ambiance, together with superior object-relational SQL operations throughout the federated facts sources, corresponding to recursive SQL, standard desk expressions (CTEs), and greater. If the remote information supply would not have this capacity, DB2 will compensate for the missing services.

    in all probability the greatest advantage to a federated system is that builders simplest need to gain knowledge of a single dialect of SQL; namely, the DB2 ANSI-compliant SQL API. If an external data source has different information varieties or non-typical SQL, DB2 will transparently make amends for missing capabilities and convert data types. for instance, SQL Server 2005 has a money facts type whereas DB2 uses a DECIMAL information type to support currency. with out the WebSphere Federation Server expertise, a developer would need to know the changes between these statistics servers, or solid them to like facts varieties using OLE DB. With WebSphere Federation Server, builders just code as if they had been all the time gaining access to DB2 facts, and the rest is looked after.

    An example of federated entry is proven in determine 1-14.

    Figure 1-14

    figure 1-14 The energy of federation—any information, one API

    In figure 1-15 which you can see the know-how add-ons that make up a federated database. Nicknames are used to implement a low form of granularity with recognize to the statistics sources you want to make accessible. Nicknames nearly are local aliases on far flung tables, however they will also be mapped to particular rows and columns. a collection of nicknames is observed inside a server that represents that specific information source. as an example, in figure 1-15 Oracle is one such information source, so the server part would signify a particular Oracle database. all of the SQL finally flows through a wrapper, which is a library of code that allows entry to a specific class of statistics servers. Connections made to those servers use their native protocol; as an instance, the Oracle connection will use the Net8 customer.

    which you could see in determine 1-14 that with WebSphere Federation Server that you could relatively a good deal lengthen the attain of DB2 to any data supply for your atmosphere. as an example, within the existence sciences trade, scientists need entry to really expert data to help their analysis regarding drug discovery. IBM offers a set of lifestyles Sciences wrappers that can be used to build a federated system that may entry statistics advantageous to scientists, including Excel spreadsheets, picture statistics, flat information, and BLAST (basic local Alignment Search device).

    If a wrapper isn't purchasable for purchase, there is a utility developer's equipment (SDK) that you can use to construct your personal.

    DB2 Developer Workbench

    The DB2 9 Developer Workbench (DB2 DWB) replaces the DB2 8 construction center. The DB2 DWB is an Eclipse-primarily based graphical atmosphere that supports the rapid construction of DB2 SQL and Java saved approaches, SQL scalar and table user described functions (UDFs), SQL statements, XQuery statements, and internet functions. youngsters, there may be so much more to this listing. as an example, the DB2 DWB comprises an SQL editor it truly is enriched with syntax colorization and code assistants, in addition to teaming aid, examine utilities, and greater.

    The DB2 DWB is a separate tool and is maintained break free a DB2 records server. you could down load it from www-304.ibm.com/jct03001c/software/facts/db2/ad/dwb.html.

    The DB2 DWB is really supposed for power DBAs that aren't coding consultants but require rapid development information for building enterprise good judgment for their information servers. depending on your atmosphere, you may additionally pick to make use of another device like Toad for DB2 or visual Studio. Pure builders will possible choose to use the plug-ins provided with DB2 9 into their respective IDEs, however they are free to make use of the DB2 DWB. For the most half, that you may operate the equal tasks in any of the tools that IBM ships or the mixing elements in specific IDEs.

    A photograph of the Developer Workbench reveal is shown in figure 1-sixteen.

    DB2 Extenders

    DB2 Extenders present the ability to control records outside of usual rows and columns to include the manipulation of particular records types (for instance, spatial types which have linked LAT/lengthy coordinates and SQL-primarily based features to operate on them), browsing features, and more. The intention of the DB2 Extenders is to deliver for the administration of this statistics throughout the usual DB2 SQL API.

    The DB2 Extenders encapsulate the attributes, structure, and conduct of those unstructured records varieties and shops this guidance in DB2. From the developer's perspective, the DB2 Extenders seem as seamless extensions to the database and permit the construction of multimedia-primarily based purposes. In other words, a spatial facts class is not any different than a developed-in information category that they may be familiar with. This part briefly details the DB2 Extenders that are offered by IBM.

    DB2 Spatial Extender

    The DB2 Spatial Extender (DB2 SE) offers the ability to create spatially conscious information objects and save them inside your DB2 database, along with other spatially related objects like (LAT/long) coordinates and extra. just about all industries might advantage from this free know-how in DB2. for instance, the banking and finance industry may visually envelope consumer segments for brand place identification. Municipal governments might use this technology for flood simple identification, the retail business for billboard areas, and extra. This seems obvious if you consider that just about all data has some variety of spatial element to it: all of us have an tackle, merchandise in a warehouse has a stock location, and the like.

    The company advantage of the DB2 SE lies within the concept that it be a lot more straightforward to spot visually represented counsel than statistics suggested in rows and columns.

    if you happen to permit your DB2 database for the DB2 SE, you can have interaction along with your data the use of SQL or really good spatial equipment from other vendors. The element is that with the DB2 SE, DB2 understands the spatial "dialect" and the operations that you need to operate with it.

    for example, a telematics software on a PDA may also deliver its clients with an inventory of nearby chinese restaurants that serve Peking Duck according to the dynamic request of this consumer. in this case, after the customer's PDA creates a area field using global Positioning equipment (GPS) coordinates, it may generate SQL statements akin to the following:

    opt for name, DESCRIPTION, address FROM restaurants the place OVERLAPS (region, box(GETGPS(),2000,2000)) AND class = 'chinese language' AND DOC includes(MENU,'PEKING DUCK');

    OVERLAPS is a spatial function that shows involved records in a binding container described by way of the OVERLAPS boundary specification; there are many other spatial functions, together with INTERSECTS, inside, BUFFERS, and so on.

    DB2 Geodetic Extender

    The DB2 Geodetic Extender builds upon capabilities obtainable in the DB2 Spatial Extender and provides compensation for actual-world objects like the curvature of the earth's floor. The algorithms during this extender are seeking to eradicate the inaccuracies added via projections and so forth. This extender is obtainable handiest for DB2 commercial enterprise as part of the facts Geodetic management characteristic.

    DB2 net Search Extender

    The DB2 web Search Extender (DB2 NSE) combines in-memory database know-how with textual content search semantics for prime-speed textual content search in DB2 databases. looking with it will also be above all valuable in cyber web functions the place performance is an important ingredient. The DB2 NSE can add the vigor of quickly full-textual content retrieval to your DB2 applications. Its facets allow you to keep unstructured textual content documents of as much as 2 GB in databases. It offers utility builders a fast, versatile, and clever formula of looking through such documents.

    additionally, the DB2 NSE provides a wealthy set of XML searching capabilities with superior search features like sounds-like, stemming, and so forth. It is shipped free in DB2 9 (it was a rechargeable extender in DB2 eight) to facilitate non-XML index looking of XML information kept in pureXML columns.

    DB2 XML Extender

    The DB2 XML Extender is supplied with DB2 and lets you keep XML documents in DB2; it also offers you the means to shred and store XML in its component constituents as columns in assorted tables. In either case, indexes can also be defined over the points or attributes of an XML doc for quick retrieval. moreover, text and fragment search can be enabled on the XML column or its decomposed components by the use of the DB2 web Search Extender. The DB2 XML Extender can also aid you formulate an XML doc from current DB2 tables for facts interchange in enterprise-to-business environments.

    You may also keep in mind that the pureXML add-on function pack is obtainable for all DB2 9 statistics servers. indeed, this can cause confusion considering that the DB2 XML Extender is distributed for free of charge in DB2 9. remember to consider the DB2 XML Extender as stabilized technology. In other phrases, it is not any longer being more advantageous and shouldn't be considered for many XML purposes. The DB2 XML Extender's approach to storing XML is to shred the XML to relational tables or stuff it into a large object. should you use this know-how to persist XML information, you must make serious change-offs with recognize to performance, flexibility, etc. additionally, you need to use specialized functions to put into effect Spathe searches, and information types are abstracted from base DB2 records kinds. rather quite simply, the way you engage with the DB2 XML Extender isn't natural for XML programmers and DBAs alike.

    In contrast, the pureXML feature in DB2 9 offers functions such that no compromises between flexibility (what XML become designed for) and efficiency (one of the vital reasons why you need the information server to store your XML) deserve to be made when storing your XML statistics. for instance, to generate XML documents from relational tables, you essential use the SQL/XML API as a substitute of the cumbersome DB2 XML Extender capabilities. that you could validate XML files against Sods in its place of simplest document type definitions (Ds) as is the case with the DB2 XML Extender, and extra. We strongly suggest this characteristic for most of your XML-based applications.

    What to look for in a BI architecture | killexams.com real questions and Pass4sure dumps

    In-Depth

    What to look for in a BI architecture

    Driven to reduce the cost of maintaining a hodge-podge of business intelligence (BI) tools in multiple departments, and to increase the number of knowledge workers using BI tools, many firms are trying to standardize on an enterprise BI tools platform. When selecting an enterprise BI platform, firms need to pay attention to architectural issues. A BI toolset must have a strong architectural foundation to support enterprise processing requirements. It is pointless to deploy BI tools to thousands of staff, customers and suppliers if performance and reliability falter under peak loads.

    So, what should you look for?

    1. A Service-Oriented Architecture (SOA) creates shared “services” or components that encapsulate business logic inside a high-level interface. Services aren’t tied to specific apps, languages, platforms or networks. They can be invoked by any app that understands the IDL, providing a high degree of abstraction, and platform and language independence. Administrators can create multiple instances of a service on one machine, increasing availability and scalability via load balancing.

    The latest industry-standard SOA frameworks are Web services (SOAP, XML and WSDL), .NET and J2EE. Most leading BI vendors have re-architected their products to support SOA frameworks and concepts. Business Objects uses CORBA. MicroStrategy and Crystal Decisions (which has been acquired by Business Objects) each adhere to Microsoft’s COM using mostly C++ components. Cognos is migrating to a new Web services architecture (SOAP and XML) that is evident in its ReportNet product.

    2. Common frameworks across all products. Vendors that have fully implemented a SOA provide seamless integration among their products on many levels. Their products all share a GUI. More importantly, they run off the same object model and runtime meta data repository.

    Today, only MicroStrategy offers common frameworks in these areas. Most vendors have been victimized by acquisitions. Each acquired product comes with a different interface, object model and meta data. Vendors must re-code the guts of a product while maintaining the existing code base. To minimize risks, many vendors initially hide the incompatibilities by linking them into a common portal and providing shared security until they can undertake a wholesale rewrite. Cognos, for example, has taken the latter approach.

    3. Designed for server- and Web-centric processing. Most BI products have gone through the process of migrating from desktop to server-based to Web-based processing. Some haven’t completed the transition, but have made strides. For example, Business Objects, Cognos and Crystal Decisions have all released Web-based report authoring tools. MicroStrategy, which has long embraced the Web, provides nearly 100% Windows–Web functionality.

    Some vendors offer plug-ins or applets to mimic desktop functionality within a Web browser. This can be a compromise between the speed and functionality of desktop processing, and the universality and ease-of-use of a Web browser. But some firms ban applets and plug-ins for security reasons.

    4. Leverage multiple tiers appropriately. The best architectures perform processing where it makes the most sense, but this has been a challenge for some vendors. Many with desktop origins prefer to do as much processing on the desktop as possible. This is fine for some functions, but not for CPU-intensive functions.

    MicroStrategy has touted its ROLAP architecture, which did all processing within a relational database by generating native SQL. Last year, the firm backed off a pure ROLAP approach with its “Intelligent Cube” architecture that does some processing on a mid-tier server to boost performance in large-scale environments.

    5. Solid systems engineering. In delivering a scalable, high-performance BI architecture, the devil is in the systems engineering details. A good BI architecture provides sophisticated use of memory, CPU processing, storage, caching, clustering, load balancing, database pooling and session management. The architecture should also run on Windows and Unix. Some vendors are awaiting 64-bit architectures to expand their ability to cache data in memory and speed processing.

    Reporting and OLAP engines require specific types of engineering to ensure good performance. Report servers need to support bursting, streaming and paging. OLAP engines must support a multi-cube architecture and fast calculations to speed load times and ensure scalability.

    6. Leverage modern architecture standards. The best BI architectures leverage the latest standards and technology, but it is difficult to re-architect a product, so it’s sometimes good to be a newcomer. Informatica has built its PowerAnalyzer tool on top of Web app servers like WebSphere, which provide a robust platform for building and supporting Web apps. These servers handle core infrastructure services, like security, clustering, fault tolerance, session management, database access and portals. Most other vendors work with Web app servers, but don’t take full advantage of these infrastructure services since they were forced to build those services into their BI platforms prior to the advent of the specialized Web servers.

    It’s also important for vendors to support emerging BI standards, such as MDX and ODBO for OLAP processing, and the Common Warehouse Metamodel for meta data management and interchange.

    Although it’s easy to tell which platforms a product supports and whether it uses applets or DHTML to support Web-based report authoring, it is hard to evaluate a BI architecture unless you test it in a production environment. The only way to do that is to require the vendor to create a prototype app using your data and queries and then stress test the prototype using a load-testing program.

    Some vendors may balk at this since it is time-consuming and expensive. But making them do it will tell you how badly they want your business and how well they are likely to support you.

    Mainframe at your service | killexams.com real questions and Pass4sure dumps

    Mainframe at your service

    Service-oriented architecture is making big iron a first-class player — again

  • By Rutrell Yasin
  • Jul 10, 2006
  • When officials in Tarrant County, Texas, decided to implement a service- oriented architecture two years ago, their goal was to link a multitude of information technology systems that didn’t communicate with each other. But they didn’t think their mainframe computer would remain a part of that equation.

    It turns out that they, like many others, misjudged the mainframe’s prospects. “The mainframe now is the predominant first-class citizen in the environment, to a point where we’re buying another one next year,” said Steve Smith, chief information officer for the county, which has a population of 1.8 million people. Fort Worth is the county seat.

    Why the change of heart? The mainframe turned out to be the most cost-effective solution for moving and processing data, and it has a high level of security and reliability, Smith said.

    Once written off as relics of a bygone era, mainframe computers are making a resurgence sparked in part by the push toward service-oriented architecture. SOA provides a framework for developing software components to manage data communications among different systems.

    The future of the mainframe looked grim in the 1990s, as a wave of inexpensive, industry-standard servers powered the rise of a more nimble, client/server distributed computing architecture. Pundits began writing epitaphs for the big iron mainframe systems, which were best known for their seemingly old-fashioned, centralized processing of big workloads.

    But the pendulum began to swing back in the mainframe’s favor with the approach of the new millennium, as IT managers realized that the mainframe has few equals when it comes to reliability and security. Also helping the image makeover was IBM’s launch in 2000 of a trimmer and more agile mainframe, the zSeries, running an updated operating system, the z/OS.

    With the advent of SOA and new standards for software interoperability such as those in the Web services family of protocols, managers in businesses and government agencies want to take advantage of their huge investments in high-end computers by extending mission-critical mainframe applications to these new mixed computing environments.

    No longer can mainframes be considered second-class citizens in a distributed computing environment, relegated to just batch processing jobs or serving as a storage site for massive amounts of vital data.

    Mainframe users, industry analysts, IBM and independent software vendors all see a new role for mainframes in the SOA paradigm, although their views vary on the exact nature of that role.

    IBM officials view the mainframe as bedrock for building out SOA, because creating and deploying new software services put new demands on network performance and security — traditional strong suits of the mainframe.

    “Mainframes, which process much of the world’s most strategic information and applications, are now finding second careers as the hub for SOA,” said Steve Mills, senior vice president and group executive of IBM’s Software Group, in a May press release announcing new software and initiatives to help developers build SOA-ready mainframe applications.

    But being a hub doesn’t mean that the mainframe will become the place where all service requests from other systems will be routed, said Dale Vecchio, a research vice president at Gartner.

    “On the other hand, service-oriented architecture as a modernization strategy for mainframe applications is absolutely occurring,” Vecchio said. Mainframes are becoming service providers on top of existing transactions, at least at the high end of the mainframe scale, he said.

    The mainframe is not the right platform for every Web application, agreed Jim Rhyne, a distinguished engineer at IBM. Many organizations have developed a significant number of Web-based applications to run on the Unix, Windows and Linux-based servers that have proliferated in their IT departments in recent years.

    Rather than spelling the end of the mainframe, this diverse picture is spurring interest in IBM’s Linux mainframes and Websphere middleware, which offer a lot of SOA and multiplatform integration capability, he added.

    Rally ’round the bus“Actually what we are seeing a lot of — and hearing — is that SOA is a key piece of business modernization, not just mainframe modernization,” said Robert Rosen, president of Share, an IBM users group. Users “can make use of their older systems in this new environment because basically what you do is take older applications and you plug them into that enterprise system bus so you can share the information or the data across the different applications.”

    Tarrant County officials used enterprise service bus software from Sonic Software to forge integration between multiple systems, Smith said.

    Until a year ago, the county’s data center wasn’t a pretty picture. There was the IBM zSeries mainframe, spewing about 18 inches of wiring for the highly customized interfaces that connected the mainframe to the other systems. Any change or modification to that setup would have caused a disastrous cascade effect, Smith said.

    “So we overlaid a nice bus architecture, a grid that ties all of the systems together,” Smith said. “It allows us to retrieve the information without having to undo the old stuff and provide new services without having to fight through 20 years of bad architecture.”

    “So, on the top we are doing new [applications] and underneath we are disconnecting the spaghetti from the different machines,” he said.

    Next year, county officials want to be able to swap platforms in and out without workers knowing or caring where the data they are using came from. At an application level, the bus architecture is also being used to integrate the county’s justice systems into a single view, so law enforcement officials can keep track of people from the time they enter jail to their release from custody, Smith said.
