Using ITCAM for SOA to monitor BPM Systems: Part 3: Using Service-to-Service topology view
The Service-to-Service topology view exposes the application
invocation transaction and execution path by topology diagram view. This article explains what is the Service-to-Service topology and how to read the Service-to-Service topology. The Service-to-Service topology view is very clear and simple for small systems with few apllications, processes and simple service invocation styles. However, the topology diagram would become very complex if there are many applications in WDPE and the invocations are complex. This article also described some best practices and methodologies to filter and reorganize the Service-to-Service topology to be more understandable.

Availability and Response Time Management in SOA environment with Tivoli Composite Application Manager for Transactions: A case study
As Service Oriented Architecture (SOA) is becoming increasingly important in software integration, an application built on SOA infrastructure is not standalone, instead, it depends on other applications. While some of these depended applications are inside the enterprise, some others are external applications provided by third-party providers. The complexity of the system, as a result, increases the difficulty to quickly sense and isolate application’s availability and response time problem. This article analyzes a typical application availability and response time management case in SOA environment, and presents a solution based on ITCAM for Transactions 7.1.

Exposing RESTful services using an Enterprise Service Bus
As REpresentational State Transfer (REST) is becoming more popular, more
non-RESTful service consumers and providers need to be adapted to make use of the REST invocation style. For such an adaptation, the Enterprise Service Bus can provide required mediation to expose non-RESTful services to be invoked RESTfully without the need to make changes to those services. This article shows how you can expose services RESTfully using IBM WebSphere Enterprise Service Bus, IBM WebSphere Message Broker and IBM WebSphere DataPower along with examples on how to test this work and sample consumers using different programming platforms.

How to identify unused indexes in DB2 for Linux, UNIX, and Windows
During database application development, developers tend to define a large number of
indexes on tables to guarantee that each and every query performs well.
After application development has been
finished and a database has gone into production, the existence of too many indexes turns
out to be a cause for decreased
database performance.
Many indexes mean more work for the database system when executing UPDATE, INSERT, and
DELETE (UID) operations.
In addition, regular maintenance activities like RUNSTATS and REORG also run
considerably longer in cases where many indexes are present.
Therefore, to achieve the best database performance, it is
critical to be able to determine which indexes are necessary for query execution and which
indexes you can
safely drop without impacting query runtimes.
This article explains several methods that a DB2 for Linux, UNIX, and Windows (DB2 LUW) database
administrator (DBA) can use to identify unused and seldom used indexes.

Moving to a Service Oriented Architecture (SOA) brings many benefits to businesses, allowing for greater solution
alignment and agility. Making this a smooth transition requires a special level of focus
on quality and an awareness of the unique challenges related to testing within an SOA.
Often, the adjustments that need to be made to testing competencies are not
apparent or planned. Organizations need to understand the unique goals and
challenges related to evolving services architecture and the implications of how testing
should be performed. In this article we will discuss the quality assurance challenges to
be addressed with a SOA adoption, recommended best practices and lessons learned.

SOA antipatterns
Service-Oriented Architecture (SOA) is the de-facto architectural approach
for many IT initiatives. It is therefore important to understand the
circumstances where this paradigm breaks, as this can significantly impact
the delivery of IT programs. This article highlights two SOA antipatterns that
define problems that can occur in the execution of SOA deliveries. A
simple frame of reference for SOA is first introduced in the form of a layered
reference architecture. The reference architecture is then used to illustrate the
underlying reasons for the occurrence of the antipatterns. For each antipattern a description is provided that highlights the root causes of the problem and the approaches to re-factoring the solution, hence facilitating successful delivery.

SOA Governance – How Best To Embrace it, Part 1: Introduction to Enterprise, IT and SOA governance
With immense projected growth, the Government must modernize its IT systems. Air traffic will double or even triple in the next twenty years, the number of retirees will double throughout the States, infrastructure will boom, the population will skyrocket, and under such pressures, the legacy systems will surely collapse, and if no action is taken, problems will abound.
Some government agencies have considered Service Oriented Architecture (SOA) as the most effective means to address this dire issue. Moving to SOA, however, entails substantial challenges. To this end, one of the government agencies requested IBM to collaborate with other partners of the agency and produce a whitepaper that addresses these challenges. This article expounds such information beyond this agency to industries across the board.

Integrating Rational Software Architect with Rational Data Architect
Model-driven software development generally starts with either application
modeling or data modeling. Application modeling and data modeling, however, are closely
related to, and complement, one another. IBM has recognized the importance of
integrating application modeling with data modeling in model-driven software
development, and has developed the Unified Modeling Language (UML)-to-Logical Data
Model (LDM) and the LDM-to-UML transformations. These transformations integrate
application modeling using Rational Software Architect (RSA) and data modeling using
Rational Data Architect (RDA). This article provides a quick overview of RSA and RDA,
outlines the high-level steps in three RSA-RDA integration scenarios, and discusses the
UML-to-LDM and the LDM-to-UML transformations and the UML Logical Data Model Profile. [2009 Apr 17: Added note about Rational Data Architect changing product

The operational context diagram
For many years, application architects and analysts have used the system
context diagram (SCD) as a powerful tool to share the high-level view of
a system. The SCD provides only a functional
view of the system, a view that later leads to the use case model. To
completely specify the system under development, non-functional requirements
must be taken into account. NFRs create another view of the system
context: the operational context diagram, which then segues to
the operational model. In this article, learn about a technique to complement
the SCD with a non-functional oriented operational context diagram.

Cloud computing with Linux
Cloud computing and storage convert physical resources (like processors and
storage) into scalable and shareable resources over the Internet (computing and storage
"as a service"). Although not a new concept, virtualization makes this much more scalable
and efficient through the sharing of physical systems through server virtualization. Cloud
computing gives users access to massive computing and storage resources without their
having to know where those resources are or how they're configured. As you might expect,
Linux plays a huge role. Discover cloud computing, and learn why there's a penguin behind
that silver lining. [And see the new Resource links to the latest developerWorks content on cloud computing. -Ed]

Solve the Chinese geography translation problem in Google Maps
programming
Google Maps is a free service that provides browser-based directions as well as maps of particular locations through the Internet. You can zoom in on the interactive maps to show detailed information, providing great user interactivity with the Web site. The maps provided by Google can be used not only directly by customers, but also to develop customized map services and products with the Google Maps API. The latest Google Maps API version, however, is not good at parsing Chinese geography, which makes it difficult to use in applications for a Chinese audience. In this article, we describe a feasible solution, combining other Web services, to parse Chinese geography with the current Google Maps API for a Chinese mapping solution. We'll use the example of the sites for the Beijing 2008 Olympic Games to demonstrate our solution.

Infrastructure architecture essentials, Part 3: System design methods for scaling
In an ideal world, all systems would have linear scaling of all
resources with linear cost, but this is rarely the case. Cost may include not
only capital expenditures but operational costs for increased cooling, power,
rack space, and management requirements. System designers and solution
architects who plan ahead for scaling can at least control cost, make initial
trade-offs for the long term, and provide mostly linear scaling with similar
increases in capital and operating costs. Choosing the right scaling
strategy--ranging from simple server-client to clusters to grid, cloud, or
general Internet services--up front is critical. This article arms systems
designers and solution architects with methods for success.

Infrastructure architecture essentials, Part 2: Find, avoid, and eliminate system bottlenecks
Systems will always have resource limits that define performance bounds. The term
"bottleneck" implies that a system has a resource imbalance and therefore a rate-limiting
stage in processing that leaves costly resources underutilized. In theory, a perfectly
resource-balanced, infinitely scalable system should never have a bottleneck or
wasted resources. Discover methods and tools for finding, eliminating, and avoiding system
bottlenecks so that you can provide the highest performance at the lowest cost for
applications and users.

Predict user mobility in enterprise networks
With the advent of high-speed, high-bandwidth mobile radio technologies
and low-power, high-computing mobile devices, enterprise-application users are
becoming increasingly mobile, rather than remaining fixed or nomadic. To
migrate existing real-time applications of such users to these high-mobility networks,
knowledge of user movement is essential. In the absence of this knowledge,
reestablishing the network-side application context of users can be costly
and lead to performance bottlenecks. In this article, learn about a behavioral
design pattern for mobility prediction in a nomadic, mobile, or an ad-hoc
network.

The evolving role of the business analyst
Traditionally, the business analyst has been responsible for analyzing the
business needs of companies by identifying business problems and proposing
solutions. With the advent of Service-Oriented Architecture (SOA), the

business logic as rules for easier and faster change cycles. Thus, a new
position called the business rules analyst has emerged. This article will
examine the role of this new star in the business world and will also help you
understand how this role can help improve the return on investment (ROI) on
your business applications.

Describe REST Web services with WSDL 2.0
At their core, Web services define a mechanism for machine-to-machine
interaction using a network and XML. A key component of a Web service is a formal
description with Web Services Description Language (WSDL). Until recently there was
no formal language to describe REpresentational State Transfer (REST) Web services -- now there's WSDL 2.0. This
article introduces you to REST
and WSDL 2.0, and walks you through creating a WSDL 2.0 description of a REST Web

Increase business agility through BRM systems and SOA
The widespread acceptance of Service-Oriented Architecture (SOA) proves that
enterprises have realized the promise of this technology. That promise of increased
agility comes from a basic software design principle: loose coupling. SOA allows for
business functions to be exposed as independent services. Web services, which is one
way to implement SOA, makes any business functionality available over the Internet.
Another technology that promises to extend that agility to business users is
business rules management (BRM) systems. A BRM system gives business users direct
control over the business logic, allowing them to change it without much
intervention from IT. This article explores how these two technologies--SOA and
BRM--promise to help businesses respond more quickly and cost effectively to
changing market conditions.

Software as a Service: Web service mediation patterns for dynamic routing of multiple tenant requests using WebSphere DataPower SOA Appliances
Explore one of three IBM middleware based mediation patterns for rapid
enablement of multi-tenancy for existing Web services implementations. This first
pattern demo uses WebSphere DataPower Appliances.
$@!LessThan!@$!--
The remaining two patterns will show the
use of WebSphere Business Services Fabric and WebSphere Enterprise Services Bus.--$@!GreaterThan!@$
In this demo, a scenario shows where multi-tenancy is enabled for a existing single tenant credit
check service by introducing a WebSphere DataPower Appliance based mediation pattern layer. This pattern layer uses a WebSphere DataPower Appliance Web service proxy and simple XSL routing policies to route service invocations from a tenant bank's user to endpoints dedicated to that tenant. The proxy also authenticates and authorizes users against policies configured in Tivoli Access Manager.

Software as a Service: Simplified tenant provisioning using IBM entry level middleware
This demo focuses on the ease of provisioning new tenant banks in a sample
banking application through the use of Apache ANT scripts and a few portlets for the
administrator roles. A new WebSphere Application Server Community Edition virtual
host and security realm are provisioned through ANT scripts invoked from a new
service provider administrator portlet. A new openLDAP user database is created and
new LDAP Data Interchange Format (LDIF) files imported through another ANT script. The portal for the new tenant bank is customized through a tenant administrator portlet by modifying style sheets, providing tenant specific images and uploading and deploying these to the running application. Custom fields are added to other portlets which use XML columns defined in DB2 Express-C V9 through simple configuration steps in a tenant administrator portlet.

Selecting a human task with custom properties using WebSphere Process Server
WebSphere Process Server V6.1 provides a technology called the Human Task Manager (HTM) that manages the life cycle of people interactions with business processes. An instance of a human interaction is called a task. Associated with a task is meta data called properties. Solution designers and developers can define some of these properties, known as custom properties. This article illustrates the use of custom properties for human tasks to locate specific task instances.

Web services hints and tips: Design reusable WSDL faults
We all agree that defining Web Services Description Language (WSDL) faults
is good (if you disagree, then you're probably not reading this article). There are
a number of ways to define WSDL faults, but only a limited subset provides for
reuse. This article presents you with a template for reusable WSDL faults, shows you
how the template is reusable, and identifies some things you should avoid.

Introduction to business rules
Business rules have existed since companies started automating business
processes using software applications. Traditionally, they have been buried deep
inside the application in some procedural programming language. As business rules
matured, business users tried to control and manage these rules without directly
having to deal with IT, which hasn't always been successful. Using an example from
the insurance industry, this article provides an introduction to business rules and
the importance of Business Rules Management Systems (BRMS) in bridging the gap
between business and IT.

Modernize legacy systems using an SOA approach
To remain competitive, your organization has to modernize its IT systems.
Modernized IT solutions must create new value from existing systems and provide
flexibility and easy interoperability among a broad set of technologies -- usually a
challenge with legacy applications. Service-Oriented Architecture (SOA), widely
adopted by organizations in recent years, offers a practical solution for evolving
and reusing existing assets. This article shows you a typical approach to
modernizing your legacy systems, including identifying the IT pieces that must be
augmented with new features, determining how the required augmentations are
performed, exposing each capability through a modern interface, and using the newly
exposed services to automate future business processes.

A practical application of SOA
Over the last few years, Service-Oriented Architecture (SOA) has received a
lot of attention, bringing with it a new age of software development and business
agility. However, SOA alone doesn't solve the world's IT problems. We still need
solid and effective software engineering practises, as a poorly managed SOA
implementation can go as wrong (if not more so) as any other architectural
approach. This article presents a practical view to SOA, from both the technology
and business perspectives, and presents a case study drawn from real-world
experiences, showing the benefits that can be achieved through a successful SOA
implementation.

Build a resilient SOA infrastructure, Part 1: Why blocking application server threads can lead to a brittle SOA
Resiliency -- defined as the continued availability and performance of a
service despite negative changes in its environment -- is vital in a
Service-Oriented Architecture (SOA). An SOA infrastructure must ensure that a
service is highly available regardless of unpredictable conditions, such as sudden
and significant degradation of network latency, increase in database response times,
or degradation of dependant services. This article, the first in a series that
describes design issues and techniques for building resilient SOA infrastructures,
focuses on how IBM WebSphere Application Server for z/OS factors into the SOA and
how it contributes to SOA resiliency.

Beef up SOA with real-time data integration
Service-Oriented Architecture (SOA) is a popular method for
designing enterprise applications, because it provides benefits like reusable
components and platform-independent communication. When considering an SOA, it's
essential to factor in data integration. A great deal of legacy data is derived from
daily transactions and must be maintained as part of new applications. If you can
combine both SOA and data-integration technologies, you benefit through reusability,
increased communication with other enterprise applications, and the use of Web
services. This article explains how IBM WebSphere DataStage helps make
this possible. DataStage, an IBM flagship product, provides a complete solution for
real-time data integration (RTI) that can be handled as a Web service. You'll use
DataStage to develop a sample RTI job, publish it as a Web service, and invoke the
Web service with a Java client.

Building SOA composite business services, Part 10: Providing governance over service consumption using WebSphere Process Server
and WebSphere Service Registry and Repository
Generally the focus of SOA governance has been on the service provider side,
especially in terms of the service lifecycle. Very little attention has been given
to the consumer or subscriber side. Who should be able to see or discover
the relevant service endpoints? Or how can someone who has discovered a service
send a request to consume the service? Or what is the process associated with
authorizing access to the service? Answers to these questions vary from customer to
customer. This article answers these questions in the context of a fictitious
prototype composite application called Jivaro Bank, and it shows how WebSphere(R)
Service Registry and Repository and WebSphere Process Server can be used to
implement governance over service consumption and subscription.

SOA meets situational applications, Part 1: Changing computing in the enterprise
As Service-Oriented Architecture (SOA) comes of age, gaining wider
acceptance in the enterprise, the Web 2.0 buzz grows louder -- perhaps matching the
SOA hype of two years ago. Many clients and colleagues are asking, "What's the
relationship between the SOA and situational applications?" "Are they orthogonal or
complementary?" "Who cares about the distinction, and are these relevant to two
totally different audiences?" This article covers the applicability of Web-based
situational applications (SAs) to the enterprise, their relationship to SOA, and how
you can use them to improve the current state of corporate IT. Learn about the IBM
experience in building the Situational Applications Environment (SAE), which was
developed to support the community-based computing that takes advantage of both
traditional SOA and emerging Web 2.0 technologies and approaches. Also, examine
several SAs, and learn about their business situations and challenges,
architectures, tangible business results, technologies that enabled the solution,
and the lessons learned.

Best practices for service interface design in SOA, Part 2: Using services to report errors to service consumer applications
In this article, learn how to report service errors using service interfaces in an
SOA environment. Service-Oriented Architecture (SOA) emphasizes loose coupling between
different systems within an enterprise. Applications communicate with each other only
with well-designed service interfaces and remain unaware of each others'
implementation. Service interface structure is of primary importance in SOA. Poorly
designed service interfaces can have a negative effect on all applications that need
to use them. Find out how well-designed service interfaces help accelerate project schedules and make your SOA solution more responsive to business needs.

Developing a Web service using an industry-specific messaging standard
Web services are a key ingredient of service-oriented computing and
Service-Oriented Architecture (SOA).
Interactions between service consumers and service providers are primarily
message-based. The structure of these messages is defined in a serviceâs interface
definition, specified in Web Services Description Language (WSDL). Organizations are
increasingly moving toward supporting industry-specific messaging standards. This
article describes an approach to developing a Web service that
uses the ACORD messaging standard for an insurance industry client. With the help of
an example, you can see how a Web service definition is created based on business
process decomposition, including mapping data elements to their respective standard
schema elements. You can also see considerations when dealing with schema
maintenance, data binding, and data typing during runtime and build time. While this
article offers only a glimpse into what is needed to fully utilize a standard message
model, it tries to describe one key aspect of it and serves as a starting point for
further discussion.

Building SOA composite business services, Part 9: Business process parallel activities pattern for flexibility and
configurability
This is the ninth installment of the series that addresses development of
composite business services (CBS). A CBS can be composed from existing SOA services
or created as a new service, designed for composability, or both. This article
introduces a parallel activities pattern that is used to design Business Process
Execution Language (BPEL)
processes for CBS. The article provides a banking use case example of realizing the
pattern to create a flexible and configurable business process in a simple
application built from CBS. The article describes a solution to a realistic use case
implemented by leveraging BPEL parallel activities. Multiple
concurrent processes are instantiated such that the number of concurrent processes
can be based on a variable, runtime-specified number of business objects. The article begins with a
brief introduction of the parallel activities pattern, followed by a use case for a
loan request in which you will learn how to use the parallel activities pattern to realize
flexibility and configurability.

Generate Web services for DB2 9 pureXML
Web services are important building blocks to achieve service-oriented architecture. As more and more applications move towards a Service Oriented Architecture, often times there is a need to expose application functionality as Web services. The purpose of this article is to show how you can easily generate Web services using a simple Java class to insert and retrieve XML data, into, and from DB2 9 using the pureXML feature. Once the Web services are generated and deployed on WebSphere Application Server, you can test it using either the built in Web services Explorer of Rational Application Developer (RAD) or XForms as a Web services client. The same services can be used by any Web services client that can make SOAP over HTTP Web service calls.

Enable REST with Web services, Part 1: REST and Web services in WSDL 2.0
For clients to interact with remotely hosted resources, REpresentational
State Transfer (REST) is fast becoming an alternative for Web services, especially
because REST doesn't require users to understand and use SOAP. There are ongoing
debates as to which one is better suited in today's highly interactive environment.
However, recent efforts, including Web Services Description Language (WSDL) 2.0,
have tried to give Web services the ability to benefit from REST and use REST
concepts. The HTTP binding specification, available in WSDL 2.0 adjuncts, talks a
lot about this. The first part of this article focuses on how REST is married to Web
services in WSDL 2.0. The second part explains how it's being implemented in the
Apache Web services project.

Integrate batch scheduling in an SOA using Tivoli Workload Scheduler V8.3 Web services
Most IT and business processes are executed via batching. And as your business grows, so do the volume and complexity of your batch workloads. That's why orderly, reliable sequencing and management of process execution is so essential to IT management -- and scheduling is its nucleus. You also need to be able to expose your batch jobs as services that can be reused to create new business processes or change existing ones. This article shows you how to use the Web services interface in IBM Tivoli Workload Scheduler Version 8.3 to expose any kind of Tivoli Workload Scheduler batch job -- including job control languages (JCLs), scripts, executables, and SAP R/3 process chains -- as a service. You'll also learn how to use Tivoli Workload Scheduler from IBM WebSphere Process Server to create customer business processes in a Service-Oriented Architecture (SOA).

Quality busters: Reduce application complexity
From a user perspective, the reliability of an application is the perceived degree to which that application delivers the desired service at the desired time with the desired accuracy. If users think that an application is unreliable, they are reluctant to use it. Therefore, an architect must seriously evaluate the application's reliability. One way to improve reliability is to reduce the number of possible failure points in the application's event path.

They consider these factors to be the domain of life-and-death environments like spacecraft software, nuclear power plant control systems, and medical equipment. But even business software can have safety concerns. An improperly processed financial transaction might cause long-lasting harm to a customer or to the business itself. In this article, I introduce failure modes and effects analysis (FMEA) and risk assessments as important tools for business software architects.

Quality busters: Treat everyone equally
Developers sometimes work on systems that are more powerful than the average end user's system. If the developer doesn't recognize the differences between his or her environment and the user's environment, then the end user may reject the developer's work as being unusable. Thus, it is important that enterprise software development implement testing and efficiency measurements with the end user in mind. Development might need to make trade-offs regarding code versions, supported environments, and testing resources.

Is your application ready for the latest version of the operation system it runs on or the program product on which it depends? Will you have to modify your application to upgrade? Have you made assumptions about the operating environment? These and other questions are easier to answer if you build portability into your application -- even if you do not plan to run it on another platform. One key to portability lies in not making any assumptions.

This article will summarize the scenarios and the various types of implementation practices that were utilized during the detail design and development phases in building the solutions. The implementation practices to be covered are in many cases a level of detail lower than what was outlined in the five business scenarios which all Web services implementers will need to consider for their business integration solutions.

Configuring your solution with WebSphere Portal, WebSphere Application Server, and WebSphere MQ
Creating applications that provide a Web front-end to a set of enterprise backend systems involves installing and configuring several products to work together. This paper provides advice for configuring such a solution with WebSphere Portal, WebSphere Application Server, and WebSphere MQ. The example solution uses WebSphere Portal to provide the Web front end, WebSphere Application Server as the application server, and WebSphere MQ for the messaging layer to the other enterprise back-end systems. This paper also describes IBM's autonomic computing efforts with respect to configuration, and describes how this work will make configuration easier in the future.

Provide a Facade interface for enterprise Web services
Enterprise information systems (EISs) can offer powerful functionality to users. However, their raw interfaces are often anything but friendly, supplying and demanding data that is often irrelevant to a particular user's needs. In this article, Masahiro Ohkawa shows you how to use WebSphere Application Developer, Enterprise Edition, to create a Facade interface that stands as a mediator between an enterprise service and the outside world. He uses a concrete example to illustrate Web services' ability to hide complexity and get users the information they need -- and nothing else.

A new look and a new foundation for IBM developerWorks
developerWorks unveils its new look -- a series of enhancements to the design and navigation of the site based largely on input from readers like you. Under the surface, our infrastructure has changed to integrate and take advantage of WebSphere Portal. With one DNS change, developerWorks has moved from using WebSphere Application Server 4.0.6 in a single Web site model to using WebSphere Portal 4.1.4 in an aggregated Web site model. Portlets and Web services let us pull together content and applications and present that content and those applications to you through our single portal-based interface. This article summarizes how -- and why -- we did it.

Using Cooperative Portlets in WebSphere Portal V5
With cooperative portlets, you can coordinate the behavior of multiple portlets in a seamless fashion. This extension to the Click-to-Action technology introduced in WebSphere Portal V4, adds a persistent connection, called a wire, between portlets. Property transfers can occur as a side-effect of user interactions with a source portlet, so that users no longer have to explicitly pick an action on the target from a menu.
