  Event-Driven SOA: Events meet Services | Guido Schmutz Oracle ACE Director Guido Schmutz shows you how to achieve extreme loose coupling within a Service-Oriented Architecture by using event-driven interactions. Misconceptions About Software Architecture | Sanjeev Kumar A concise, to-the-point, and informative article by Sanjeev Kumar. Good Leaders Acknowledge What Can't Be Done - Jeffrey Pfeffer - Harvard Business Review "None of us likes to admit to bad decisions," says Jeffrey Pfeffer. "But imagine how much harder that is for someone who has been chosen to lead a large organization precisely because he or she is thought to have the power to see the future more clearly and chart a wise course." Suboptimal Thinking within Enterprise Architecture | James McGovern McGovern says: "We need to remember that enterprises live and thrive beyond just the current person at the helm." Boundaryless Information Flow | Richard Veryard "If all the boundaries are removed or porous, then the (extended) enterprise or ecosystem becomes like a giant sponge, in which all information permeates the whole," Veryard says. "Some people may think that's a good idea, but it's not what I'd call loose coupling." Coming to a City Near You: Oracle Business Analytics Summits | Rob Reynolds This series of events includes a Technology and Architecture track. New Date for Implementation of Sun Hands-On Course Requirement (Oracle Certification) As announced on the Oracle Certification website, Java Architect, Java Developer, Solaris System Administrator and Solaris Security Administrator certification tracks will include a new mandatory course attendance requirement. VirtualBox 4.0.10 is now available for download | Bob Netherton Netherton shares information on the new release. Updated Technical Best Practices whitepaper | Anthony Shorten The Technical Best Practices whitepaper has been updated with the latest advice. "New advice includes new installation advice, advanced settings, new security settings and advice for both Oracle WebLogic and IBM WebSphere installations," says Shorten. Kscope 11 ADF, AIA and Business Rules | Peter Paul van de Beek Whitehorses Solution Architect Peter Paul van de Beek shares his impressions of KScope11 presentations by Markus Eisele, Sten Vesterli, and Edwin Biemond. Amazon AWS for the learning experience | Andrej Koelewijn "Using AWS changes your expectations how your internal data center should operate," says Koelewijn. BPMN is dead, long live BPEL! (SOA Partner Community Blog) Jürgen Kress shares information -- including a long list of speakers -- for the SOA & BPM Integration Days 2011 conference, October 12th & 13th 2011 in Düsseldorf. InfoQ: HTML5 and the Dawn of Rich Mobile Web Applications James Pearce introduces cross-platform web apps development using HTML5 and web frameworks, such as jQTouch, jQuery Mobile, Sencha Touch, PhoneGap, outlining what makes a good framework. InfoQ: Interview and Book Excerpt: CMMI for Development "Frameworks like TOGAF are used to define an architecture that aligns IT assets and resources to support key business needs and processes of key stakeholders," says SEI's Mike Konrad. "But the individual application systems, capabilities, services, networks, and other IT assets and infrastructure still need to be acquired, developed, or sustained." InfoQ: Architecting a Cloud-Scale Identity Fabric | Eric Olden "The most cited reason for not moving to the cloud is concern about security," says Olden. "In particular, managing user identity and access in the cloud is a tough problem to solve and a big security concern for organizations."

• Windows Azure Use Case: Hybrid Applications

  - by BuckWoody

  This is one in a series of posts on when and where to use a distributed architecture design in your organization's computing needs. You can find the main post here: http://blogs.msdn.com/b/buckwoody/archive/2011/01/18/windows-azure-and-sql-azure-use-cases.aspx  Description: Organizations see the need for computing infrastructures that they can “rent” or pay for only when they need them. They also understand the benefits of distributed computing, but do not want to create this infrastructure themselves. However, they may have considerations that prevent them from moving all of their current IT investment to a distributed environment: Private data (do not want to send or store sensitive data off-site) High dollar investment in current infrastructure Applications currently running well, but may need additional periodic capacity Current applications not designed in a stateless fashion In these situations, a “hybrid” approach works best. In fact, with Windows Azure, a hybrid approach is an optimal way to implement distributed computing even when the stipulations above do not apply. Keeping a majority of the computing function in an organization local while exploring and expanding that footprint into Windows and SQL Azure is a good migration or expansion strategy. A “hybrid” architecture merely means that part of a computing cycle is shared between two architectures. For instance, some level of computing might be done in a Windows Azure web-based application, while the data is stored locally at the organization. Implementation: There are multiple methods for implementing a hybrid architecture, in a spectrum from very little interaction from the local infrastructure to Windows or SQL Azure. The patterns fall into two broad schemas, and even these can be mixed. 1. Client-Centric Hybrid Patterns In this pattern, programs are coded such that the client system sends queries or compute requests to multiple systems. The “client” in this case might be a web-based codeset actually stored on another system (which acts as a client, the user’s device serving as the presentation layer) or a compiled program. In either case, the code on the client requestor carries the burden of defining the layout of the requests. While this pattern is often the easiest to code, it’s the most brittle. Any change in the architecture must be reflected on each client, but this can be mitigated by using a centralized system as the client such as in the web scenario. 2. System-Centric Hybrid Patterns Another approach is to create a distributed architecture by turning on-site systems into “services” that can be called from Windows Azure using the service Bus or the Access Control Services (ACS) capabilities. Code calls from a series of in-process client application. In this pattern you move the “client” interface into the server application logic. If you do not wish to change the application itself, you can “layer” the results of the code return using a product (such as Microsoft BizTalk) that exposes a Web Services Definition Language (WSDL) endpoint to Windows Azure using the Application Fabric. In effect, this is similar to creating a Service Oriented Architecture (SOA) environment, and has the advantage of de-coupling your computing architecture. If each system offers a “service” of the results of some software processing, the operating system or platform becomes immaterial, assuming it adheres to a service contract. There are important considerations when you federate a system, whether to Windows or SQL Azure or any other distributed architecture. While these considerations are consistent with coding any application for distributed computing, they are especially important for a hybrid application. Connection resiliency - Applications on-premise normally have low-latency and good connection properties, something you’re not always guaranteed in a distributed and hybrid application. Whether a centralized client or a distributed one, the code should be able to handle extended retry logic. Authorization and Access - In a single authorization environment like a Active Directory domain, security is handled at a user-password level. In a distributed computing environment, you have more options. You can mitigate this with  using The Windows Azure Application Fabric feature of ACS to make the Azure application aware of the App Fabric as an ADFS provider. However, a claims-based authentication structure is often a superior choice.  Consistency and Concurrency - When you have a Relational Database Management System (RDBMS), Consistency and Concurrency are part of the design. In a Service Architecture, you need to plan for sequential message handling and lifecycle.

• Windows Azure Use Case: Web Applications

  - by BuckWoody

  This is one in a series of posts on when and where to use a distributed architecture design in your organization's computing needs. You can find the main post here: http://blogs.msdn.com/b/buckwoody/archive/2011/01/18/windows-azure-and-sql-azure-use-cases.aspx  Description: Many applications have a requirement to be located outside of the organization’s internal infrastructure control. For instance, the company website for a brick-and-mortar retail company may want to post not only static but interactive content to be available to their external customers, and not want the customers to have access inside the organization’s firewall. There are also cases of pure web applications used for a great many of the internal functions of the business. This allows for remote workers, shared customer/employee workloads and data and other advantages. Some firms choose to host these web servers internally, others choose to contract out the infrastructure to an “ASP” (Application Service Provider) or an Infrastructure as a Service (IaaS) company. In any case, the design of these applications often resembles the following: In this design, a server (or perhaps more than one) hosts the presentation function (http or https) access to the application, and this same system may hold the computational aspects of the program. Authorization and Access is controlled programmatically, or is more open if this is a customer-facing application. Storage is either placed on the same or other servers, hosted within an RDBMS or NoSQL database, or a combination of the options, all coded into the application. High-Availability within this scenario is often the responsibility of the architects of the application, and by purchasing more hosting resources which must be built, licensed and configured, and manually added as demand requires, although some IaaS providers have a partially automatic method to add nodes for scale-out, if the architecture of the application supports it. Disaster Recovery is the responsibility of the system architect as well. Implementation: In a Windows Azure Platform as a Service (PaaS) environment, many of these architectural considerations are designed into the system. The Azure “Fabric” (not to be confused with the Azure implementation of Application Fabric - more on that in a moment) is designed to provide scalability. Compute resources can be added and removed programmatically based on any number of factors. Balancers at the request-level of the Fabric automatically route http and https requests. The fabric also provides High-Availability for storage and other components. Disaster recovery is a shared responsibility between the facilities (which have the ability to restore in case of catastrophic failure) and your code, which should build in recovery. In a Windows Azure-based web application, you have the ability to separate out the various functions and components. Presentation can be coded for multiple platforms like smart phones, tablets and PC’s, while the computation can be a single entity shared between them. This makes the applications more resilient and more object-oriented, and lends itself to a SOA or Distributed Computing architecture. It is true that you could code up a similar set of functionality in a traditional web-farm, but the difference here is that the components are built into the very design of the architecture. The API’s and DLL’s you call in a Windows Azure code base contains components as first-class citizens. For instance, if you need storage, it is simply called within the application as an object.  Computation has multiple options and the ability to scale linearly. You also gain another component that you would either have to write or bolt-in to a typical web-farm: the Application Fabric. This Windows Azure component provides communication between applications or even to on-premise systems. It provides authorization in either person-based or claims-based perspectives. SQL Azure provides relational storage as another option, and can also be used or accessed from on-premise systems. It should be noted that you can use all or some of these components individually.

(tags: oracle sun wsdl webservices DSEE netbeans jdeveloper) Nick Wooler: Iron-Clad Cloud: Secure Cloud Computing "One solution to the security problem with cloud services can be overcome using Service Oriented Security. The Oracle approach to using Service Oriented Security allows developers to pull from a centralized, authoritative source of identity services. This allows developers to build security into every application from the inside-out. This is critical to ensuring this is done in a standardized manner and most importantly it allows developers to develop without being security experts." -- Nick Wooler (tags: oracle sun security cloud saas) Andy Mulholland: A week of visits; Cisco, HP, Oracle, SAP and VMware (in alphabetical order!) "I now am considering that we should be thinking about ‘clouds’ in virtual way, by which I mean that a succession of virtual ‘clouds’ will need to exist, each possessing specific characteristics that suit certain types of services. Really it’s no different to what we see with servers today. Adding a hypervisor to a server adds new flexibility, but creating a virtualised environment means much more. What I suspect will happen is that we will start to use vendor specific approaches to building what I will term a physical cloud solution using their technology and approach to supporting a specific objective, but with time we will find these physical clouds will interoperate as a fully virtualised cloud environment." -- Andy Mulholland (tags: entarch enterprisearchitecture cloudcomputing virtualization) @fteter: Highlights From The Bright Lights - Tuesday #c10 Oracle Ace Director Floyd Teter of JPL with one last wrap-up of Collaborate 10.

• Windows Azure Use Case: Agility

  - by BuckWoody

  This is one in a series of posts on when and where to use a distributed architecture design in your organization's computing needs. You can find the main post here: http://blogs.msdn.com/b/buckwoody/archive/2011/01/18/windows-azure-and-sql-azure-use-cases.aspx  Description: Agility in this context is defined as the ability to quickly develop and deploy an application. In theory, the speed at which your organization can develop and deploy an application on available hardware is identical to what you could deploy in a distributed environment. But in practice, this is not always the case. Having an option to use a distributed environment can be much faster for the deployment and even the development process. Implementation: When an organization designs code, they are essentially becoming a Software-as-a-Service (SaaS) provider to their own organization. To do that, the IT operations team becomes the Infrastructure-as-a-Service (IaaS) to the development teams. From there, the software is developed and deployed using an Application Lifecycle Management (ALM) process. A simplified view of an ALM process is as follows: Requirements Analysis Design and Development Implementation Testing Deployment to Production Maintenance In an on-premise environment, this often equates to the following process map: Requirements Business requirements formed by Business Analysts, Developers and Data Professionals. Analysis Feasibility studies, including physical plant, security, manpower and other resources. Request is placed on the work task list if approved. Design and Development Code written according to organization’s chosen methodology, either on-premise or to multiple development teams on and off premise. Implementation Code checked into main branch. Code forked as needed. Testing Code deployed to on-premise Testing servers. If no server capacity available, more resources procured through standard budgeting and ordering processes. Manual and automated functional, load, security, etc. performed. Deployment to Production Server team involved to select platform and environments with available capacity. If no server capacity available, standard budgeting and procurement process followed. If no server capacity available, systems built, configured and put under standard organizational IT control. Systems configured for proper operating systems, patches, security and virus scans. System maintenance, HA/DR, backups and recovery plans configured and put into place. Maintenance Code changes evaluated and altered according to need. In a distributed computing environment like Windows Azure, the process maps a bit differently: Requirements Business requirements formed by Business Analysts, Developers and Data Professionals. Analysis Feasibility studies, including budget, security, manpower and other resources. Request is placed on the work task list if approved. Design and Development Code written according to organization’s chosen methodology, either on-premise or to multiple development teams on and off premise. Implementation Code checked into main branch. Code forked as needed. Testing Code deployed to Azure. Manual and automated functional, load, security, etc. performed. Deployment to Production Code deployed to Azure. Point in time backup and recovery plans configured and put into place.(HA/DR and automated backups already present in Azure fabric) Maintenance Code changes evaluated and altered according to need. This means that several steps can be removed or expedited. It also means that the business function requesting the application can be held directly responsible for the funding of that request, speeding the process further since the IT budgeting process may not be involved in the Azure scenario. An additional benefit is the “Azure Marketplace”, In effect this becomes an app store for Enterprises to select pre-defined code and data applications to mesh or bolt-in to their current code, possibly saving development time.

  Why business needs should shape IT architecture - McKinsey Quarterly - Business Technology - Organization "Too often, efforts to fix architecture issues remain rooted in a company’s IT practices, culture, and leadership. The reason, in part, is that the chief architect—the overall IT-architecture program leader—is frequently selected from within the technical ranks, bringing deep IT know-how but little direct experience or influence in leading a business-wide change program. A weak linkage to the business creates a void that limits the quality of the resulting IT architecture and the organization’s ability to enforce and sustain the benefits of implementation over time." -- Helge Buckow and Stéphane Rey (tags: architecture it technology enterprise mckinsey) Eric Maurice: April 2010 Critical Patch Update Released Eric Maurice offers the details on April 2010 Critical Patch Update (CPUApr2010), "the first one to include security fixes for Oracle Solaris" (tags: oracle otn database fusionmiddleware peoplesoft security) @shivmohan: Oracle – OAF – Oracle Application Framework – OA Framework "For all the PL/SQL and Oracle Forms developers out there, start planning your evolution.

• Pins on Pinterest link to 404 - yet link is valid

  - by Damian Rees

  this is a really strange one. I've set up a bunch of pins on Pinterest linking through to our services which all work fine. Then I decided to do the same on our blog articles (we use Wordpress), yet everytime I click the link (and I've done this on different computers) the link goes to a 404 page on our site. However the link is valid and if you right click the pin and open in new window it opens fine. I have contacted Pinterest who are next to useless. I have also tried different browsers, different computers and different Pinterest accounts. I can't see any weirdness in my htaccess files causing this so I'm a little stumped. Any suggestions?

(tags: oracle otn fusionmiddleware b2b) Java 2 Go!: How to write a simple yet “bullet-proof” object cache "So, while we were thinking hard to come up with the most efficient, generic and elegant way of finally implementing our weak and soft caches, Mr. Eric Chan, who is one of the main architects in Oracle Beehive team, had a very interesting breakthrough. In short terms, he thought of a very nice way of combining both WeakReference and SoftReference in our weak and soft caches so that they would provide exactly the same functionality without having to deal with those reference queues at all. Basically, instead of using a plain HashMap as our backing storage, we used a java.util.WeakHashMap in both our cache implementations. The hat trick was what and how to store things in it." - Eduardo Rodrigues (tags: oracle java sun) @jamet123: First Look – Oracle Data Mining "[Oracle Data Mining] is a nice product for Oracle database customers and well worth looking into.

  @lucasjellema: Book review -- Getting Started With Oracle SOA Suite 11g R1: A Hands-On Tutorial "I have to confess that I may be biased – or at least that I have a personal stake in books about the SOA Suite. I am currently in the final stages of writing the Oracle SOA Suite 11g Handbook, published by Oracle Press (see http://www.mhprofessional.com/product.php?isbn=0071608974 and http://wiki.oracle.com/page/Oracle+11g+SOA+Suite+Handbook for some supporting material and early screenshots) which you could consider a competitor to the book I am discussing here. I would suggest however that the two are quite complementary: after reading the Getting Started With Oracle SOA Suite 11g R1: A Hands-On Tutorial and concluding that you want to learn more and delve deeper into the SOA Suite and the concepts around it, it would make perfect sense to read my book, Oracle SOA Suite 11g Handbook, as that takes you to the next level." -- Oracle ACE Director Lucas Jellema of Amis Technology (tags: oracle otn oracleace soa bookreview soasuite) Terri Noyes: The Scoop: Oracle E-Business Suite Support on 64-bit Linux Terri Noyes addresses frequently asked questions about Oracle E-Business Suite (EBS) 64-bit Linux support.
