IBM IBM WebSphere Application Server
IBM used its DeveloperWorks live convention in San Francisco to promulgate 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: contemporary records puts IBM both on degree footing or just forward of its chief compete 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 subsist maturity of the software server market is prompting some to remark that the primary players gain extra or less reached functional parity with their products, IBM says its latest efforts parade it's forward of the expertise curve. The expertise component is simply Part of the touchstone 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 resolve 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 every the artery through the third quarter. Key updates encompass replete 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 plane 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 revolve 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 achieve not wish to fabricate 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 novel and rebundled types of its integration application that are designed to simplify the pricing and packaging structure and profile a springboard for drawing nigh 'verticalized' releases.
New applied sciences include the WebSphere MQ sustain broking service, an extension to IBM's message queuing household that makes it practicable 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 institute in gigantic 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 Part 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 seize 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 chain of chew-sized modules designed mainly for a number upright industries. The deliverables gain yet to arrive, however IBM says every the fundamental ISV partnerships are in location for a launch within the next month or so.

On the puss of it the query would peruse obviously amenable to the adage that for any headline with a question tag in it the reply is no. but a few months in the past at a conference i used to subsist speaking to someone steeped in the world of open supply standardisation, having been Part 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 subsist alert 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 paramount in statistics middle computing over a *long* length of time, unless a mixture 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 infatuation Satya Nadella’s flip at Microsoft – with a renaissance in line with open standards, open supply, and being a very cordial 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 ample touch 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 gain 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 novel vogue of industry standards surroundings. IBM’s gain an sequel on remains very big in every of those open supply foundations, placing its weight in the back of the Linux basis’s evolution to furthermore exploit the Node.js foundation and The Cloud endemic Computing basis.
So privilege here they are in 2019, IBM soundless has that seat on the desk, and now it’s acquiring pink Hat, which additionally had a big 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 every of those communities. while Java and Linux are very a lot ripen commodity applied sciences, Node continues to subsist 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 outline the commerce over the following few years. IBM + red Hat is an extremely potent gain an sequel on bloc.
my very own seize is that, principally as many within the industrial open supply supplier space panic the role of net infrastructure groups, specially Amazon net features, the touch of IBM should doubtless subsist 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 subsist hugely influential in industry instructions for the nigh future. descry the chart above from a submit by using Tomasz Tunguz at Redpoint Ventures for a sense of the size of wager being made privilege here. As Tunguz argues:
pink Hat offers three businesses of application items: operating apparatus (Linux and virtualization); utility construction (application server/JBoss); novel 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 novel Infrastructure is the quickest becoming, doubling 12 months over yr.
I regard 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 complex technologies infatuation Kubernetes for significant firms.
So IBM has a pretty cordial shielding/self-cannibalisation possibility around Websphere, a extend company in Linux, however the precise kicker for boom is red Hat OpenShift, as they flow into what I even gain report 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 valuable contributor to Kubernetes, however red Hat has finished more than any one else to even the weight.
So achieve individuals gain intent to subsist anxious? i'm relatively assured in the management of IBM individuals infatuation Todd Moore, VP of Open technology, and their talent to achieve the confiscate thing for the commerce as a whole, nevertheless it became nevertheless in fact appealing to listen to someone from the trade mutter they gain been now fearful of IBM, on account of its dominance in a brace of valuable 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 every purchasers.

This chapter is from the reserve
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 Part of a DB2 client are packaged on their own, outside of a client installation. DB2 drivers proffer a more lightweight deployment option for specific API connectivity.
DB2 Connect™—This add-on product provides uphold 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 every of the DB2 mainstream editions that race on Linux, UNIX, and Windows. It's made up of two components, CAPTURE and APPLY. It uses SQL to replay data on target servers.
Q-Replication is built on the IBM WebSphere MQSeries® technology and is generally thought to subsist a more available and powerful replication technology. You can add this capability to a DB2 environment through one of the WebSphere Information Integrator products.
WebSphere Information Server or WebSphere Federation Server—The WebSphere brand has a suite of products that assist you publish, place, cleanse, transform, enrich, and access data across heterogeneous data sources.
WebSphere Application Server—A Part of this application server is shipped with DB2. It allows developers to exhaust Java as a platform in a transaction processing environment.
Once a DB2 application has been developed, you requisite to install connectivity software on each client workstation in a two-tier environment. If you are deploying a Web-based application in a three-tier environment, you requisite to, at a minimum, install the DB2 client connectivity software on the application server. 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 uphold connectivity to DB2 9 data servers (the exception to this is if you elect to uphold communication via specific API drivers, covered later in this section). When you install a DB2 Runtime Client, you install a driver to uphold every the common programming methodologies, including ADO.NET, ADO, OLE DB, ODBC, JDBC, SQLJ, static SQL, and more.
Using a DB2 Runtime Client you can effect 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 every the functions institute 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 lieutenant 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 institute 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 seize 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 preference of which DB2 client to install should subsist based on the requirements of the application on the client machine. For example, if you gain a database application developed for Linux, UNIX, or Windows and you achieve not require the DB2 administration or application progress tools from a Windows workstation, yet want to uphold applications written in multiple programming languages infatuation .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 requisite to access the DB2 Runtime Client code remotely from a code server before accessing to DB2. This sort of configuration is known as a thin client. A thin-client configuration can provide many benefits, such as a central catalog directory of every database connections and a unique 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 subsist 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 requisite to ensure that a DB2 Runtime Client is installed on each workstation executing the application. motif 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 very server, connectivity is considered to further from a local client. If the application is installed on a system other than the DB2 data server, its connectivity is considered to further from a remote client.
Figure 1-10 Accessing a DB2 data server using the DB2 Runtime Client
DB2 client connectivity can subsist configured using various supported communication protocols. The supported protocols vary according to operating system:
TCP/IP—used in every environments
Named Pipe—used in Windows environments
Some larger enterprises and independent software vendors (ISVs) want to deploy their applications written in unique 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 subsist deployed for connectivity on their own, outside of a DB2 Runtime Client or DB2 Client installation.
The IBM Driver for JDBC and SQLJ can subsist deployed to uphold Java-based connectivity to a DB2 data server. This driver is about 2 MB in size and can easily subsist 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 requisite to additionally license this connectivity with DB2 Connect (covered in the next section) to ensure you are compliant with respect to licensing.
It's valuable 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 uphold data server connectivity using other APIs. For example, you can't uphold 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 novel standalone driver for CLI and ODBC applications called the IBM DB2 Driver for ODBC and CLI. This driver delivers the very 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 requisite to gain DB2 RTCL or DB2 Client installed on the client machines
Same concept as the JDBC/SQLJ driver but for ODBC/CLI applications
DB2 Connect is a divorce 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 gain 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 achieve 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 infatuation CICS and VSAM) transparent to the world's most common 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 novel deployments on distributed platforms, modernize the application progress sustain for mainframe progress (for example, moving 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 descry in motif 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 gain DB2 Connect on its own or collocated with the application server. Depending on your configuration, you may or may not requisite to install a DB2 client.
Figure 1-11 Using DB2 Connect is a single-tier or multi-tier environment
DB2 Connect products can subsist 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 fabricate the connection to a mainframe DB2 resource, but you soundless requisite to purchase a telling 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, every of the DB2 Connect editions proffer the very role and features; they are merely differentiated by capability. every 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 unique workstations and doesn't provide its users with any server capabilities. Using DB2 Connect PE, you can fabricate direct connections to DB2 running on the mainframe. In motif 1-11, the desktop users likely gain 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 fabricate direct connections using the DB2 Connect PE software for sure 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 seize advantage 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 subsist 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 isolate 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 every the applications servers that connect to the mainframe. The VUs that you purchase gain nothing to achieve 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 gain to buy 1,000 VUs of DB2 Connect ASE. DB2 Connect ASE is well suited for environments where you expect to descry 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 basis 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 gain flat mainframe cycle growth and heavy 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 require to perambulate 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 circumstantial in this section. In fact, the title DB2 Connect is deceptive because connectivity is just a petite Part of what this product can do; however, these details are outside the scope of this book.
DB2 Replication allows for data to subsist 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 uphold a wide variety of data servers, including DB2, Oracle, Microsoft, Sybase, Informix, IMS, Lotus Notes, and flat files with WebSphere Replication Server.
An specimen of SQL-based replication is shown in motif 1-12. SQL-based replication has been around for over a decade and has proven itself to subsist extremely flexible, resilient, smooth to set up, and scalable.
Figure 1-12 SQL-based replication extended with WebSphere Replication Server
In motif 1-12 you can descry the broad achieve of the SQL-based replication technology when it is extended with the WebSphere Replication Server product. As you may recall, distributed versions of DB2 further with the DPROPR technology built in and can uphold 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 motif 1-12.
When you buy WebSphere Replication Server, you furthermore find Q-based replication (Figure 1-13). In Q-based replication, each message represents a transaction that is placed on a WebSphere MQ chain message queue. This replication is known for its highly parallel apply process and loaded fight 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 institute in WebSphere Information Server, namely the federation capabilities (and hence will subsist 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 unique virtual database to terminate 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 uphold enables the DB2 data server to evaluate global statistics on every data sources in order to optimize requests for the remote data. For example, the global optimizer can exhaust scholarship of source statistics, source indexes, source functions, server and network speeds, and so on.
The SQL uphold in a DB2 federated environment supports the very 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 gain this capability, DB2 will compensate for the missing functions.
Perhaps the greatest profit to a federated system is that developers only gain to learn a unique vernacular 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 sort whereas DB2 uses a DECIMAL data sort to uphold currency. Without the WebSphere Federation Server technology, a developer would gain to know the differences between these data servers, or cast them to infatuation 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 supervision of.
An specimen of federated access is shown in motif 1-14.
Figure 1-14 The power of federation—any data, one API
In motif 1-15 you can descry the technology components that fabricate up a federated database. Nicknames are used to implement a low profile of granularity with respect to the data sources you want to fabricate available. Nicknames essentially are local aliases on remote tables, although they can subsist mapped to specific rows and columns. A collection of nicknames is located within a server that represents that actual data source. For example, in motif 1-15 Oracle is one such data source, so the server component would picture a specific Oracle database. every 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 descry in motif 1-14 that with WebSphere Federation Server you can pretty much extend the achieve of DB2 to any data source in your environment. For example, in the life sciences industry, scientists requisite access to specialized data to uphold their research related to drug discovery. IBM offers a set of Life Sciences wrappers that can subsist used to build a federated system that can access data useful to scientists, including transcend spreadsheets, image data, flat files, and nip (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:

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 every 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 subsist on a platform that is different from the one on which the application will eventually subsist deployed or tested because of the common code basis used in the distributed DB2 environment. In fact, almost any applications developed using DEDE can subsist 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 common methodologies, including:
Call plane Interface (CLI)/Open Database Connectivity (ODBC)
.NET Framework 2.0
DB2 Application Programming Interfaces (APIs)
Java Database Connectivity (JDBC) and SQLJ
Ruby on Rails™
DEDE furthermore includes the necessary programming libraries, header files, code samples, and pre-compilers for every 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 divorce tool and is maintained divorce 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 tool infatuation Toad for DB2 or Visual Studio. sheer developers will likely elect 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 effect the very 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 motif 1-16.
DB2 Extenders proffer the talent to exploit data outside of conventional rows and columns to include the manipulation of special data types (for example, spatial types that gain 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 intimate 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 materialize as seamless extensions to the database and enable the progress of multimedia-based applications. In other words, a spatial data sort is no different than a built-in data sort that they may subsist 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 alert data objects and store them within your DB2 database, along with other spatially related objects infatuation (LAT/LONG) coordinates and more. Almost every industries could profit 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 plain identification, the retail industry for billboard locations, and more. This seems evident when you consider that almost every data has some sort of spatial component to it: they every gain an address, merchandise in a warehouse has a stock location, and so on.
The commerce profit 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 effect 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
OVERLAPS (LOCATION, BOX(GETGPS(),2000,2000))
AND CATEGORY = 'CHINESE'
AND DOC CONTAINS(MENU,'PEKING DUCK');
OVERLAPS is a spatial role that shows interested data in a binding box defined by the OVERLAPS frontier 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 infatuation the curvature of the earth's surface. The algorithms in this extender quest to remove the inaccuracies introduced by projections and so on. This extender is available only for DB2 Enterprise as Part 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 subsist particularly advantageous in Internet applications where performance is an valuable factor. The DB2 NSE can add the power of lickety-split 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 bright method of searching through such documents.
Additionally, the DB2 NSE provides a loaded set of XML searching capabilities with advanced search features infatuation 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 subsist defined over the elements or attributes of an XML document for lickety-split retrieval. Furthermore, text and fragment search can subsist enabled on the XML column or its decomposed parts via the DB2 Net Search Extender. The DB2 XML Extender can furthermore assist 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 every DB2 9 data servers. Indeed, this can occasions 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 subsist 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 big object. When you exhaust this technology to persist XML data, you gain to fabricate staid trade-offs with respect to performance, flexibility, and so on. In addition, you gain to exhaust specialized functions to implement Spathe searches, and data types are distraught from basis 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) requisite to subsist 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 sort 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 revolve to find the services treatment
By Deborah Melewski
While the software industry focused on Java, .NET and Web services in recent years, the mainframe became an afterthought. It was expected to fade away.
But IT shops are now waking up to find that the mainframe soundless runs the key enterprise applications, and that the mainframe margin 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 requisite 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 fade with the Verastream Host Integrator product from WRQ Inc., Seattle.
According to Judith Franklin, manager of enterprise technology uphold at DVS, the division’s goal was to help data character and accuracy, as well as turnaround time to commerce partners and the drivers of Minnesota. Challenges were plentiful. To begin 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 seize 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 subsist entered. In addition, there were a lot of data-entry errors.
“Based on their commerce model, if you needed to find a driver’s license or renewal, or register a vehicle or transfer a title, you had to fade to their commerce partners who could subsist the cities, counties or private individuals in commerce for themselves,” said Franklin. “You would fade there, achieve your paperwork and they in revolve would dispatch us the paperwork. And there it would sit, a distinguished 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 achieve something dramatically different,” Franklin said.
Franklin institute two or three Cobol programmers who knew the system inside and out. As is often the case with legacy systems, there was very miniature documentation. The screens were typical CICS screens, and could not subsist 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 achieve something efficacious -- 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 perambulate away from that database.
“We required a tool 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 tool supple enough to appropriate into wherever they would subsist 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 fade 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 mutter 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 novel system, they can access a current, readable driver’s record. More than 10 million photos can subsist stored using the SQL database, and the records are integrated with the photos.
The division has taken data entry out to every 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 every 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 lop 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 scholarly that it would every 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 infatuation that slip by.”
Performance is key
“People are finding that they requisite to perambulate their applications to the Web to fabricate it easier for their customers and partners to achieve 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 requisite to perambulate quickly to the Web, so re-creating commerce logic and data on novel platforms is just not possible, he added. “They’re starting to step back and say, ‘We already gain 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 fabricate the creation of these novel applications quicker and give them higher functionality.’”
WRQ’s Verastream product is a runtime server with design tools. It works with products infatuation 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 uphold setting layers of granularity. Many approaches to integration in the past failed, notable Rosenbloom, because when people started using services infatuation 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 gain this very challenge -- if you just expose the existing API via Web services, you could gain very low-level, fine-grain calls going on. For example, if you’re updating a realm or a record as opposed to sending an entire document replete of many records that you may want to submit every at once,” Rosenbloom explained.
“It’s very valuable that you implement Web services with the privilege plane of granularity when you fabricate this Web service convoke 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 infatuation HTTP over the network, and there are a lot of different things going on; you want to ensure that when you fabricate that convoke over the network, it will achieve a lot of work for you before it returns.”
