IBM IBM WebSphere App Server
On the pan of it the question would glance evidently amenable to the adage that for any headline with a query notice in it the reply is no. however a few months in the past at a convention i used to live talking to somebody steeped in the world of open source standardisation, having been a Part of the Node.js ecosystem for years and he pointed out:
“For the first time in a long long time i am fearful of IBM.”
For these of you too immature to stand in intelligence the olden days IBM become the Google of its day, the Microsoft of its day, the AWS of its day. because the epigram went: “IBM isn’t the competition, it’s the ambiance during which you compete.” IBM became fully predominant in records core computing over a *long* length of time, until a mix of antitrust law, trade structural alterations, and administration blunders compelled the enterprise on to the again foot. The tenure of Louis Gerstner on the helm of IBM changed into a tiny bit like Satya Nadella’s eddy at Microsoft – with a renaissance in keeping with open requisites, open source, and being a pretty fine group partner. by the time I entered the industry IBM changed into nevertheless an impressive player, but no longer the monster of ancient. It quiet had big repercussion over business resolution making. If IBM talked about a technology became equipped for the enterprise then by definition it was. IBM made Java an enterprise normal. IBM made Linux an commercial enterprise ordinary. IBM made open source a realistic business resolution. IBM didn’t just motivate purchasers to adopt these technologies besides the fact that children – it demanded affect, a seat at the necessities-atmosphere table, with the aid of contributing developer hours, funds, and beget an repercussion on. The Apache application groundwork. The Eclipse basis. Latterly the Linux groundwork. IBM did more than anybody to establish open source implementation as the unique style of trade requirements environment. IBM’s move is quiet very colossal in obscene of those open supply foundations, placing its weight behind the Linux groundwork’s evolution to additionally manage the Node.js foundation and The Cloud autochthonous Computing foundation.
So privilege here we're in 2019, IBM quiet has that seat at the table, and now it’s acquiring crimson Hat, which additionally had a sizable footprint in these communities. The deal to purchase pink Hat is exactly what made the adult above afraid. Java, Linux, Node.js and Kubernetes – IBM has a powerful play in obscene of these communities. while Java and Linux are very lots develope commodity applied sciences, Node remains setting up itself as an business average. commercial enterprise adoption of Kubernetes, and associated application tasks reminiscent of Prometheus and Grafana, in the meantime, is going to outline the business over the following yoke of years. IBM + crimson Hat is an exceedingly powerful beget an consequence on bloc.
my very own enmesh is that, above obscene as many within the business open supply vendor house concern the function of internet infrastructure companies, in particular Amazon web capabilities, the move of IBM should probably live welcomed. these days at IBM’s believe event my colleague Stephen O’Grady seemed on stage with IBM CEO and Chairman Ginny Rometty talking in regards to the ongoing critical of open supply to IBM and the business. The red Hat deal is profession defining for her, and should actually live vastly influential in trade instructions for the near future. note the chart above from a consequence up through Tomasz Tunguz at Redpoint Ventures for a sense of the dimensions of wager being made privilege here. As Tunguz argues:
crimson Hat offers three agencies of software items: operating device (Linux and virtualization); application progress (utility server/JBoss); unique Infrastructure (OpenShift, OpenStack and Ansible). profits contribution across these categories is sixty four%, 23% and 13%. The core infrastructure (operating device and app building) are definitely top notch groups, growing to live between 10-25% annually. the unique Infrastructure is the quickest growing, doubling 12 months over 12 months.
I esteem pink Hat’s OpenShift platform because the chief in business platform-as-a-carrier. OpenShift gives a coincident progress atmosphere for application engineers. OpenShift simplifies the deployment and administration of advanced applied sciences like Kubernetes for huge organisations.
So IBM has an exceptional protective/self-cannibalisation opening around Websphere, a growth company in Linux, but the precise kicker for boom is pink Hat OpenShift, as they circulate into what I actually beget report as a secular shift round Kubernetes. literally every commercial enterprise they speak is asking at Kubernetes because the foundation for a tremendous infrastructure overhaul – everybody runs K8s or is going to. Google is quiet the foremost contributor to Kubernetes, however pink Hat has accomplished greater than any one else to even the burden.
So conclude folks beget intent to worry? i am pretty confident in the leadership of IBM individuals like Todd Moore, VP of Open know-how, and their capacity to conclude the privilege thing for the trade as a whole, but it turned into quiet definitely entertaining to hear someone from the business articulate they were now stupefied of IBM, on account of its dominance in a number of well-known trade necessities. It’s been a very long time because that became the case.
additional reading – my boy Stephen wrote a really exceptional publish in regards to the IBM crimson Hat consolidation play.
full disclosure: AWS, IBM, red Hat, Microsoft and Google are obscene valued clientele.

This chapter is from the book
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 offer a more lightweight deployment option for specific API connectivity.
DB2 Connect™—This add-on product provides advocate 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 obscene of the DB2 mainstream editions that flee 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 live 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 serve 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 necessity 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 necessity 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 advocate connectivity to DB2 9 data servers (the exception to this is if you select to advocate communication via specific API drivers, covered later in this section). When you install a DB2 Runtime Client, you install a driver to advocate obscene the common programming methodologies, including ADO.NET, ADO, OLE DB, ODBC, JDBC, SQLJ, static SQL, and more.
Using a DB2 Runtime Client you can accomplish 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 obscene the functions organize in the DB2 Runtime Client plus functions for client-server configuration, tools for database administration and application development, samples, and more. For example, this client includes the Configuration assistant that provides graphically administration and connectivity tools, as well as a host of programming samples, and so on. The DB2 9 Client replaces the functions organize in both the DB2 8 Application progress and DB2 8 Administration clients.
A DB2 Client's footprint is directly correlated to the components you select to install and can enmesh 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 live based on the requirements of the application on the client machine. For example, if you beget a database application developed for Linux, UNIX, or Windows and you conclude not require the DB2 administration or application progress tools from a Windows workstation, yet want to advocate applications written in multiple programming languages like .NET and Java, you should install the DB2 Runtime Client on that workstation.
Some enterprises prefer to deploy the DB2 Runtime Client code remotely on a dedicated server. In these environments, remote workstations necessity to access the DB2 Runtime Client code remotely from a code server before accessing to DB2. This type of configuration is known as a thin client. A thin-client configuration can provide many benefits, such as a central catalog directory of obscene database connections and a lone 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 live renowned however that this performance hit is only "noticed" on the initial connection. Once the client code is loaded on the client workstation, subsequent calls to the code server are not needed.
When you want to deploy your DB2 application, you only necessity to ensure that a DB2 Runtime Client is installed on each workstation executing the application. 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 near from a local client. If the application is installed on a system other than the DB2 data server, its connectivity is considered to near from a remote client.
Figure 1-10 Accessing a DB2 data server using the DB2 Runtime Client
DB2 client connectivity can live configured using various supported communication protocols. The supported protocols vary according to operating system:
TCP/IP—used in obscene environments
Named Pipe—used in Windows environments
Some larger enterprises and independent software vendors (ISVs) want to deploy their applications written in lone 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 live deployed for connectivity on their own, outside of a DB2 Runtime Client or DB2 Client installation.
The IBM Driver for JDBC and SQLJ can live deployed to advocate Java-based connectivity to a DB2 data server. This driver is about 2 MB in size and can easily live embedded within your application. In fact, it comes with a royalty-free distribution license for this very purpose.
You should note however that although this driver can connect to the entire DB2 family, if you're connecting to a DB2 for i5/OS, DB2 for VM/VSE, or DB2 for z/OS data server, you necessity to additionally license this connectivity with DB2 Connect (covered in the next section) to ensure you are compliant with respect to licensing.
It's well-known 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 advocate data server connectivity using other APIs. For example, you can't advocate a .NET application using this driver. You can download this driver at www14.software.ibm.com/webapp/download/preconfig.jsp?id=2004-09-20+10%3A09%3A21.003415R&cat=database&fam=&s=c&S_TACT=105AGX11&S_CMP=DB2.
DB2 9 includes a unique standalone driver for CLI and ODBC applications called the IBM DB2 Driver for ODBC and CLI. This driver delivers the 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 necessity to beget 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 divide 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 beget 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 attain of this federation capability to heterogeneous sources by adding either WebSphere Federation Server or WebSphere Information Server.
Connection pooling and the more powerful connection concentration services that provide minimal resource consumption on the mainframe.
System z Sysplex exploitation for failover and load balancing. For example, DB2 Connect includes high-availability features such as z/OS Workload Manager Integration (WLM) and automatic re-direct to a data-sharing group.
Integration into mainstream progress environments for mainframe data access. For example, DB2 Connect makes data artifacts on the mainframe (including nonrelational-related services like CICS and VSAM) transparent to the world's most approved 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 tradition systems with unique deployments on distributed platforms, modernize the application progress sustain for mainframe progress (for example, affecting 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 note 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 beget DB2 Connect on its own or collocated with the application server. Depending on your configuration, you may or may not necessity to install a DB2 client.
Figure 1-11 Using DB2 Connect is a single-tier or multi-tier environment
DB2 Connect products can live 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 invent the connection to a mainframe DB2 resource, but you quiet necessity to purchase a cogent 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, obscene of the DB2 Connect editions offer the very function and features; they are merely differentiated by capability. obscene 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 lone workstations and doesn't provide its users with any server capabilities. Using DB2 Connect PE, you can invent direct connections to DB2 running on the mainframe. In motif 1-11, the desktop users likely beget DB2 Connect PE installed in their workstations. DB2 Connect PE can also 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 invent direct connections using the DB2 Connect PE software for inevitable 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 enmesh 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 live 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 segregate 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 obscene the applications servers that connect to the mainframe. The VUs that you purchase beget nothing to conclude 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 beget to buy 1,000 VUs of DB2 Connect ASE. DB2 Connect ASE is well suited for environments where you anticipate to note 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 foundation server license plus a per-unit impregnate for the MSU rating of the System z server you are connecting to. DB2 Connect UE is well suited for environments that beget flat mainframe cycle growth and ponderous Web tier growth as the costs of DB2 Connect UE are directly correlated with the capacity of the mainframe resource. DB2 Connect UE comes with a free copy of Mobility on require to straggle mainframe data to occasionally connected devices, as well as DB2 Connect PE. Essentially, this edition of DB2 Connect, as its designation would imply, allows for unlimited deployments.
There's so much more to the DB2 Connect product than what's particular in this section. In fact, the designation DB2 Connect is misleading because connectivity is just a tiny Part of what this product can do; however, these details are outside the scope of this book.
DB2 Replication allows for data to live propagated from one location to another. SQL-based replication, also 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 also extend this replication capability to advocate a wide variety of data servers, including DB2, Oracle, Microsoft, Sybase, Informix, IMS, Lotus Notes, and flat files with WebSphere Replication Server.
An sample 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 live extremely flexible, resilient, facile to set up, and scalable.
Figure 1-12 SQL-based replication extended with WebSphere Replication Server
In motif 1-12 you can note the broad attain of the SQL-based replication technology when it is extended with the WebSphere Replication Server product. As you may recall, distributed versions of DB2 near with the DPROPR technology built in and can advocate 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 also enmesh Q-based replication (Figure 1-13). In Q-based replication, each message represents a transaction that is placed on a WebSphere MQ sequence message queue. This replication is known for its highly parallel apply process and rich contest detection and resolution services.
WebSphere Federation Server and WebSphere Information Server
WebSphere Information Server provides features and functions to place, publish, integrate, find, cleanse, and access data. The federation capabilities are worth mentioning as they relate to data access. WebSphere Federation Server contains a subset of the functionality organize in WebSphere Information Server, namely the federation capabilities (and hence will live 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 lone 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 advocate enables the DB2 data server to evaluate global statistics on obscene data sources in order to optimize requests for the remote data. For example, the global optimizer can exhaust knowledge of source statistics, source indexes, source functions, server and network speeds, and so on.
The SQL advocate 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 beget this capability, DB2 will compensate for the missing functions.
Perhaps the greatest benefit to a federated system is that developers only beget to learn a lone dialect 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 transform data types. For example, SQL Server 2005 has a MONEY data type whereas DB2 uses a DECIMAL data type to advocate currency. Without the WebSphere Federation Server technology, a developer would beget to know the differences between these data servers, or cast them to like data types using OLE DB. With WebSphere Federation Server, developers just code as if they were always accessing DB2 data, and the leisure is taken faith of.
An sample 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 note the technology components that invent up a federated database. Nicknames are used to implement a low figure of granularity with respect to the data sources you want to invent available. Nicknames essentially are local aliases on remote tables, although they can live 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 portray a specific Oracle database. obscene 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 autochthonous protocol; for example, the Oracle connection will exhaust the Net8 client.
You can note in motif 1-14 that with WebSphere Federation Server you can pretty much extend the attain of DB2 to any data source in your environment. For example, in the life sciences industry, scientists necessity access to specialized data to advocate their research related to drug discovery. IBM offers a set of Life Sciences wrappers that can live used to build a federated system that can access data useful to scientists, including outstrip 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 obscene 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 live on a platform that is different from the one on which the application will eventually live deployed or tested because of the common code foundation used in the distributed DB2 environment. In fact, almost any applications developed using DEDE can live 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 approved methodologies, including:
Call level 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 also includes the necessary programming libraries, header files, code samples, and pre-compilers for obscene 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 divide instrument and is maintained divide 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 business logic for their data servers. Depending on your environment, you may elect to exhaust another instrument like Toad for DB2 or Visual Studio. unadulterated developers will likely select to exhaust the plug-ins provided with DB2 9 into their respective IDEs, although they are free to exhaust the DB2 DWB. For the most part, you can accomplish 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 offer the talent to manipulate data outside of conventional rows and columns to comprise the manipulation of special data types (for example, spatial types that beget 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 behavior of these unstructured data types and stores this information in DB2. From the developer's perspective, the DB2 Extenders display as seamless extensions to the database and enable the progress of multimedia-based applications. In other words, a spatial data type is no different than a built-in data type that they may live accustomed to. This section briefly details the DB2 Extenders that are provided by IBM.
DB2 Spatial Extender
The DB2 Spatial Extender (DB2 SE) provides the talent to create spatially aware data objects and store them within your DB2 database, along with other spatially related objects like (LAT/LONG) coordinates and more. Almost obscene industries could benefit 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 divide when you deem that almost obscene data has some sort of spatial component to it: they obscene beget an address, merchandise in a warehouse has a stock location, and so on.
The business benefit 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 accomplish 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 function 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 like the curvature of the earth's surface. The algorithms in this extender search 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 live particularly advantageous in Internet applications where performance is an well-known factor. The DB2 NSE can add the power of speedy 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 mode of searching through such documents.
Additionally, the DB2 NSE provides a rich set of XML searching capabilities with advanced search features like sounds-like, stemming, and so on. It is shipped free in DB2 9 (it was a chargeable extender in DB2 8) to facilitate non-XML index searching of XML data stored in pureXML columns.
DB2 XML Extender
The DB2 XML Extender is provided with DB2 and allows you to store XML documents in DB2; it also gives you the talent to shred and store XML in its component parts as columns in multiple tables. In either case, indexes can live defined over the elements or attributes of an XML document for speedy retrieval. Furthermore, text and fragment search can live enabled on the XML column or its decomposed parts via the DB2 Net Search Extender. The DB2 XML Extender can also serve 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 obscene DB2 9 data servers. Indeed, this can cause confusion since the DB2 XML Extender is shipped for free in DB2 9. You should deem the DB2 XML Extender as stabilized technology. In other words, it is no longer being enhanced and shouldn't live 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 beget to invent sober trade-offs with respect to performance, flexibility, and so on. In addition, you beget to exhaust specialized functions to implement Spathe searches, and data types are distraught from foundation DB2 data types. Quite simply, the way you interact with the DB2 XML Extender isn't natural for XML programmers and DBAs alike.
In contrast, the pureXML feature in DB2 9 provides services such that no compromises between flexibility (what XML was designed for) and performance (one of the reasons why you want the data server to store your XML) necessity to live 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 type definitions (Ds) as is the case with the DB2 XML Extender, and more. They strongly recommend this feature for most of your XML-based applications.
It’s the mainframe’s eddy to enmesh 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 travel away.
But IT shops are now waking up to find that the mainframe quiet runs the key enterprise applications, and that the mainframe leeway is due for some “home improvement.”
Application progress managers are discovering that, when it comes to refashioning mainframe apps as Web services apps, there are many different ways to go. And as Gartner Inc.’s Dale Vecchio said, they may open up a Pandora’s box if the dig too deeply into that legacy code. Developers necessity to let more -- not fewer -- users into the mainframe world, and some will opt for host-to-Web, GUI extensions and screen-scrapers as the best means to start to bring the mainframe into the realm of Web services.
When the Minnesota Dept. of Public Safety Driver and Vehicle Services (DVS) Division in St. Paul decided to integrate its legacy mainframe applications with Web services, the division chose to travel with the Verastream Host Integrator product from WRQ Inc., Seattle.
According to Judith Franklin, manager of enterprise technology advocate at DVS, the division’s goal was to improve data trait and accuracy, as well as turnaround time to business partners and the drivers of Minnesota. Challenges were plentiful. To initiate with, the system in exhaust was a largely paper-driven environment, based on a mainframe that was more than 25 years old.
When Franklin was brought in, processing a motor vehicle title transfer took between three and six months. It was not uncommon for the processing of a driver’s license to enmesh 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 live entered. In addition, there were a lot of data-entry errors.
“Based on their business model, if you needed to enmesh a driver’s license or renewal, or register a vehicle or transfer a title, you had to travel to their business partners who could live the cities, counties or private individuals in business for themselves,” said Franklin. “You would travel there, conclude your paperwork and they in eddy would forward us the paperwork. And there it would sit, a imposing 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 conclude something dramatically different,” Franklin said.
Franklin organize two or three Cobol programmers who knew the system inside and out. As is often the case with legacy systems, there was very tiny documentation. The screens were typical CICS screens, and could not live released to business partners or to the public because they contained too much information and were difficult to read.
Franklin’s first goal was to conclude something effectual -- 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 business partners. It was not necessary to enhance the current system because the DVS planned to eventually straggle away from that database.
“We required a instrument 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 also wanted a instrument resilient enough to felicitous into wherever they would live 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 business partners.
The DVS built Web apps that travel to the Verastream middleware, which then goes to the mainframe and returns data with records that are deployed and formatted for readability. The DVS is also 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 articulate that the services they now provide are the best tools they’ve been given since the mobile radio.”
Prior to Web services, law-enforcement officials had to spread out pages of papers; with the unique system, they can access a current, readable driver’s record. More than 10 million photos can live stored using the SQL database, and the records are integrated with the photos.
The division has taken data entry out to obscene 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 obscene 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 chop 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 also 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 enlarge in production, CPU cycles and database calls, which more than doubled in the first three months after opening up their mainframe to the Web,” she said. “And they erudite that it would obscene double again during the next three months.”
Also a concern: maintenance. DVS people brought everything down for maintenance one Saturday morning. “It was a one-time job on a Saturday morning, and suddenly the motor vehicle site is down and my beeper is going off,” said Franklin, admitting to some shortsightedness. “The concept is so different now that you might unwittingly let things like that slip by.”
Performance is key
“People are finding that they necessity to straggle their applications to the Web to invent it easier for their customers and partners to conclude business with them,” said Scott Rosenbloom, chief strategist at WRQ. “One of the challenges is that some 60%–70% of their information and business logic is stored on legacy systems.”
Companies necessity to straggle quickly to the Web, so re-creating business logic and data on unique platforms is just not possible, he added. “They’re starting to step back and say, ‘We already beget that business logic and information. It’s reliable, and it’s been on the host maybe 15 or more years. Let’s find a way to expose that to the Web to invent the creation of these unique applications quicker and give them higher functionality.’”
WRQ’s Verastream product is a runtime server with design tools. It works with products like Microsoft Visual Studio .NET, BEA Workshop and IBM’s WebSphere. “We expose the information with Verastream, and that is used to build the actual application,” said Rosenbloom.
The WRQ tools also advocate setting layers of granularity. Many approaches to integration in the past failed, renowned Rosenbloom, because when people started using services like CORBA they did not change the way 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 beget this very challenge -- if you just expose the existing API via Web services, you could beget 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 plenary of many records that you may want to submit obscene at once,” Rosenbloom explained.
“It’s very well-known that you implement Web services with the privilege level of granularity when you invent this Web service muster because there is a lot of overhead associated with this call,” he added. “You’re creating an XML document. You’re shipping it over a protocol like HTTP over the network, and there are a lot of different things going on; you want to ensure that when you invent that muster over the network, it will conclude a lot of toil for you before it returns.”
