  • Service Level Loggin/Tracing

    - by Ahsan Alam
    We all love to develop services, right? First timers want to learn technologies like WCF and Web Services. Some simply want to build services; whereas, others may find services as natural architectural decision for particular systems. Whatever the reason might be, services are commonly used in building wide range of systems. Developers often encapsulates various functionality (small or big) within one or more services, and expose them for multiple applications. Sometimes from day one (and definitely over time) these services may evolve into a set of black boxes. Services or not, black boxes or not, issues and exceptions are sometimes hard to avoid, especially in highly evolving and transactional systems. We can try to be methodical with our unit testing, QA and overall process; but we may not be able to avoid some type of system issues. When issues arise from one or more highly transactional services, it becomes necessary to resolve them very quickly. When systems handle thousands of transaction in matter of hours, some issues may not surface immediately. That is when service level logging becomes very useful. Technologies such as WCF, allow us to enable service level tracing with minimal effort; but that may not provide us with complete picture. Developers may need to add tracing within critical areas of the code with various degrees of verbosity. Programmer can always utilize some logging framework such as the 'Logging Application Block' to get the job done. It may seem overkill sometimes; but I have noticed from my experience that service level logging helps programmer trace many issues very quickly.

  • When Do OS Questions Belong on Hardware Service Requests?

    - by Get Proactive Customer Adoption Team
    Untitled Document My Oracle Support—Logging an Operating System Service Request One of the concerns we hear from our customers with Premier Support for Systems is that they have difficulty logging a Service Request (SR) for an operating system issue. Because Premier Support for Systems includes support for the hardware and the associated operating system, you log any operating system issues through a hardware Service Request. To create a hardware Service Request, you enter the information into the Hardware tab of the Create Service Request screen, but to ensure that the hardware Service Request you enter is recognized and routed appropriately for an operating system issue, you need to change the product from your specific hardware to the operating system that the hardware is running. The example below shows you how to create a Service Request for the operating system when the support level is Premier Support for Systems. The key to success is remembering that the operating system coverage is part of the hardware support. To begin, from anywhere within My Oracle Support, click on the Create SR button as you would to log any SR: Enter your Problem Summary and the Problem Description Next, click on the Hardware tab. Enter the System Serial Number (in this case “12345”) and click on Validate Serial Number: Notice that the product name for the hardware indicates “Sunfire T2000 Server” with an option for a drop down List of Values. Click on the product drop down and choose the correct operating system from the list. In this case I have chosen “OpenSolaris Operating System” Next, you will need to enter the correct operating system version: At this point, you may proceed to complete and submit the Service Request. If your company has Premier Support for Systems, just remember that your operating system has coverage under the hardware it runs on, so start with a Hardware tab on the Service Request screen and change the product related information to reflect the operating system you need help with. Following these simple steps will ensure that the system assigns your Service Request to the right support team for an operating system issue and the support engineer can quickly begin working your issue.

  • Is it reasonable to expect knowing the whole stack bottom up?

    - by Vaibhav Garg
    I am an Sr. developer/architect/Product Manager for embedded systems. The systems that I have had experience with have typically been small to medium size codebases - typically close to 25-30K LOC in C, using 8-16 and 32 bit low end microcontrollers. The systems have been entirely bootstrapped by our team - meaning right from the start-up code to the end application code has either been written by the team, or at the very least, is thoroughly understood and maintained by us. Now, if we were to start developing more complex systems with complex peripherals, such as USB OTG et al. (think, low end cell phones), there are libraries and stacks available commercially and from chip vendors that reduce the task to just calling the right APIs and being able to use those peripherals. Now, from a habit point of view, this does not give me and the team a comfortable feeling, not being able to comprehend the entire code tree, with virtual black boxes at the lower layers. Is it reasonable to devote, and reserve, time getting into the details of how the APIs are implemented, assuming that the same would also entail getting into details of relevant standards (again, for USB as an example)? Or, alternatively, should a thorough understanding of the top level usage of the APIs be sufficient? This of course assumes that the source codes to all libraries are available, which they are, in almost all cases. Edit: In partial response to @Abhi Beckert, the documentation is refreshingly very comprehensive and meticulously maintained, AFAIK and been able to judge. I have not had a long experience with the same.

  • Troubleshoot broken ZFS

    - by BBK
    I have one zpool called tank in RaidZ1 with 5x1TB SATA HDDs. I'm using Ubuntu Server 11.10 Oneric, kernel 3.0.0-15-server. Installed ZFS from ppa also I'm using zfs-auto-snapshot. The ZFS file system when zfs module loaded to the kernel hangs my computer. Before it I created few new file systems: zfs create -V 10G tank/iscsi1 zfs create -V 10G tank/iscsi2 zfs create -V 10G tank/iscsi3 I shared them through iSCSI by /dev/tank/iscsiX path. And my computer started to hanging sometimes when I used tank/iscsiX by iSCSI, do not know why exactly. I switched off iSCSI and started to remove this file systems: zfs destroy tank/iscsi3 I'm also using zfs-auto-snapshot so I had snapshots and without -r key my command not destroying the FS. So I issued next command: zfs destroy tank/iscsi3 -r The tank/iscsi3 FS was clean and contain nothing - it was destroyed without an issue. But tank/iscsi2 and tank/iscsi1 contained a lot of information. I tried zfs destroy tank/iscsi2 -r After some time my computer hang out. I rebooted computer. It didn't boot very fast, HDDs starts working like a crazy making a lot of noise, after 15 minutes HDDs stopped go crazy and OS booted at last. All seems to be ok - tank/iscsi2 was destroyed. After file systems at the tank was accessible, zpool status showed no corruption. I issued new command: zfs destroy tank/iscsi1 -r Situation was repeated - after some time my computer hang out. But this time ZFS seams not to healed itself. After computer switched on it started to work: loading scripts and kernel modules, after zfs starting to work it hanging my computer. I need to recover else ZFS file systems which lying in the same zpool. Few month ago I backup OS to flash drive. Booting from backed-up OS and import have the same results - OS starts hanging. How to recover my data at ZFS tank?

  • Is it bad practice for services to share a database in SOA?

    - by Paul T Davies
    I have recently been reading Hohpe and Woolf's Enterprise Integration Patterns, some of Thomas Erl's books on SOA and watching various videos and podcasts by Udi Dahan et al. on CQRS and Event Driven systems. Systems in my place of work suffer from high coupling. Although each system theoretically has its own database, there is a lot of joining between them. In practice this means there is one huge database that all systems use. For example, there is one table of customer data. Much of what I've read seems to suggest denormalising data so that each system uses only its database, and any updates to one system are propagated to all the others using messaging. I thought this was one of the ways of enforcing the boundaries in SOA - each service should have its own database, but then I read this: http://stackoverflow.com/questions/4019902/soa-joining-data-across-multiple-services and it suggests this is the wrong thing to do. Segregating the databases does seem like a good way of decoupling systems, but now I'm a bit confused. Is this a good route to take? Is it ever recommended that you should segregate a database on, say an SOA service, an DDD Bounded context, an application, etc?

  • Policy Administration is the Top 2011 IT Priority for Insurers

    - by helen.pitts(at)oracle.com
    The current issue of Insurance Networking News includes an interesting column by Novarica's Matt Josefowicz.  Recent research by the firm revealed that policy administration replacement or extension is the most common strategic IT project for insurers this year.  The article goes on to note that insurers are keenly focused on the business capabilities that can be delivered once the system is in production as well as the ability to leverage agile development methodologies and true business/IT collaboration during implementation. The results are not too surprising given that policy administration is a mission-critical system for life and annuity insurers.  As Josefowicz notes, "Core systems are called core for a reason--they are at the heart of the insurer's ability to function.  Replacing them is not to be done lightly, but failing to replace them can mean diminishing the ability to compete or function effectively as a company." Insurers can no longer rely on inflexible policy administration systems that impede their ability to rapidly configure and bring to innovative new products, add riders, support changing business processes and take advantage of market opportunities.  The ability to leverage the policy administration systems to better service customers and distribution channels by providing real-time access to policy information throughout the policy lifecycle is also critical to sustain loyalty and further fuel growth.Insurers can benefit from a modern, adaptive policy administration system, like Oracle Insurance Policy Administration for Life and Annuity.  You can learn more about the industry's most highly advanced, rules-based system, which is unmatched for its highly flexible, rules-based configurability, performance and extensibility, as well as global market industry trends by viewing a complimentary, on-demand Webcast, Adapt, Transform and Grow:  Accelerate Speed to Market with Adaptive Insurance Policy Administration.Data conversions can be a daunting process for many insurers when deciding to modernize, in particular when consolidating from multiple, disparate legacy policy administration systems to a single new platform.  Migrating from a legacy system requires a well-thought out approach that builds on the industry's best thinking from previous modernization efforts and takes data migration off the critical path by leveraging proven methodology and tools to capitalize on the new system's capabilities.  We'll discuss more about this approach in a future Oracle Insurance blog.Helen Pitts is senior product marketing manager for Oracle Insurance's life and annuities solutions.

  • Installation Problems & Antivirus

    - by Sagar Walvekar
    We have just migrated our systems from Windows to Ubuntu. We have more than 50 systems previously running Windows XP & Windows 7. After the release of 12.04 we decided to switch to Ubuntu. While we were installing Ubuntu 12.04 on Pentium 4 systems we have faced some issues. We tried it with a USB flash driver & CD. The typical configuration of the system is as follows: Pentium 4 with HT & 512 MB RAM, 40/80 GB IDE / SATA HDD. In windows there were several partitions and data on all the drives in all the systems. We have addressed this by taking backup of the C: drive on other drives & while installing Ubuntu we have just deleted & the C drive & recreated Linux partitions as follows - /root , /Boot, /Home & Swap.(in 10 GB) The problem is that the Linux gets installed without any error. However when I restart the system after the installation the system hangs in while detecting the HDD in BIOS and the system fails to start until I remove the HDD. When I installed the previous Ubuntu version it worked fine, without any hassle. Also if we install Ubuntu 12.04 on same HDD on any other higher capacity system & reconnected to old system it works fine. How can I fix this problem? Also, is there is any Antivirus which will give me real time protection on ubuntu 11 & higher versions with both 32 & 64 Bits?

  • Asset and Work Management in Utilities: An Integrated Enterprise Success Story

    - by stephen.slade(at)oracle.com
    Jan 11 '11 Webcast: Utilities are turning to Oracle to deliver an integrated EAM platform that manages all of their assets from fleet to facilities and distribution to generation. Hear from solutions experts and from Sunflower Electric Power Corporation about how an integrated enterprise asset and work management system helped them deliver bottom line results Do you have different work management systems for generation, distribution, and transmission? Fleet maintenance? Facilities? Are you on the latest release of these products? Have you considered your options when the product is no longer supported? Do you struggle with integration and keeping the various systems "in balance"? Do you have trouble retrieving data from these disparate systems and getting an enterprise view of asset and work management operations? Utilities are challenged to better manage information on generation, transmission and distribution assets. Point solutions for Enterprise Asset Management (EAM) and Computerized Maintenance Management Systems (CMMS) are often effective as departmental solutions but have limited ability to deliver an enterprise solution with accessible business intelligence.

  • Windows Azure Virtual Machines - Make Sure You Follow the Documentation

    - by BuckWoody
    To create a Windows Azure Infrastructure-as-a-Service Virtual Machine you have several options. You can simply select an image from a “Gallery” which includes Windows or Linux operating systems, or even a Windows Server with pre-installed software like SQL Server. One of the advantages to Windows Azure Virtual Machines is that it is stored in a standard Hyper-V format – with the base hard-disk as a VHD. That means you can move a Virtual Machine from on-premises to Windows Azure, and then move it back again. You can even use a simple series of PowerShell scripts to do the move, or automate it with other methods. And this then leads to another very interesting option for deploying systems: you can create a server VHD, configure it with the software you want, and then run the “SYSPREP” process on it. SYSPREP is a Windows utility that essentially strips the identity from a system, and when you re-start that system it asks a few details on what you want to call it and so on. By doing this, you can essentially create your own gallery of systems, either for testing, development servers, demo systems and more. You can learn more about how to do that here: http://msdn.microsoft.com/en-us/library/windowsazure/gg465407.aspx   But there is a small issue you can run into that I wanted to make you aware of. Whenever you deploy a system to Windows Azure Virtual Machines, you must meet certain password complexity requirements. However, when you build the machine locally and SYSPREP it, you might not choose a strong password for the account you use to Remote Desktop to the machine. In that case, you might not be able to reach the system after you deploy it. Once again, the key here is reading through the instructions before you start. Check out the link I showed above, and this link: http://technet.microsoft.com/en-us/library/cc264456.aspx to make sure you understand what you want to deploy.

  • New partnership allows auto-transposition of client/server application to Windows Azure

    - by Webgui
    The economics of IT is changing rapidly, and organizations are searching to widen and secure availability of their systems and at the same time lower costs which is exactly what the cloud meant to do. Running your systems on Microsoft’s Windows Azure cloud for example would improve and secure the availability, accessibility and scalability (both up and down) of your systems and support the new IT economics. However, in order to take advantage of the cloud's promise of lower cost of ownership, the applications must be built or adjusted to work on that platform and in most cases this is not a simple task.  Even existing web applications cannot always be transferred to Azure without some changes, and for client/server applications, the task is way more challenging even to the point where it seems impossible. The reason is the gaps between the client/server desktop technology and the cloud's. For that reason, most of the known methodologies to migrate existing client/server applications actually involve rewrite of the desktop systems for the cloud. A unique approach is introduced by Visual WebGui which creates a virtualization layer atop ASP.Net web server, it moves the transformed or generated .Net code to that layer, and then using a patent pending protocol it renders a user interface within a plain browser. The end result is pure .NET code that is a base code for a pure rich web application and now due to a collaboration with Microsoft Windows Azure Visual WebGui provides the shortest path from client/server to the Azure cloud by being able to handle close to 95% of the transformation to the cloud platform in an automatic way. Application Migration to Azure without migraines More information about the Instant CloudMove Azure solution here.

  • Skanska Builds Global Workforce Insight with Cloud-Based HCM System

    - by HCM-Oracle
    By David Baum - Originally posted on Profit Peter Bjork grew up building things. He started his work life learning all sorts of trades at his father’s construction company in the northern part of Sweden. So in college, it was natural for him to pursue a bachelor’s degree in construction engineering—but he broke new ground when he added a master’s degree in finance to his curriculum vitae. Written on a traditional résumé, Bjork’s current title (vice president of information systems strategies) doesn’t reveal the diversity of his experience—that he’s adept with hammer and nails as well as rows and columns. But a big part of his current job is to work with his counterparts in human resources (HR) designing, building, and deploying the systems needed to get a complete view of the skills and potential of Skanska’s 22,000-strong white-collar workforce. And Bjork believes that complete view is essential to Skanska’s success. “Our business is really all about people,” says Bjork, who has worked with Skanska for 16 years. “You can have equipment and financial resources, but to truly succeed in a business like ours you need to have the right people in the right places. That’s what this system is helping us accomplish.” In a global HR environment that suffers from a paradox of high unemployment and a scarcity of skilled labor, managers need to have a complete understanding of workforce capabilities to develop management skills, recruit for open positions, ensure that staff is getting the training they need, and reduce attrition. Skanska’s human capital management (HCM) systems, based on Oracle Talent Management Cloud, play a critical role delivering that understanding. “Skanska’s philosophy of having great people, encouraging their development, and giving them the chance to move across business units has nurtured a culture of collaboration, but managing a diverse workforce spread across the globe is a monumental challenge,” says Annika Lindholm, global human resources system owner in the HR department at Skanska’s headquarters just outside of Stockholm, Sweden. “We depend heavily on Oracle’s cloud technology to support our HCM function.” Construction, Workers For Skanska’s more than 60,000 employees and contractors, managing huge construction projects is an everyday job. Beyond erecting signature buildings, management’s goal is to build a corporate culture where valuable talent can be sought out and developed, bringing in the right mix of people to support and grow the business. “Of all the companies in our space, Skanska is probably one of the strongest ones, with a laser focus on people and people development,” notes Tom Crane, chief HR and communications officer for Skanska in the United States. “Our business looks like equipment and material, but all we really have at the end of the day are people and their intellectual capital. Without them, second only to clients, of course, you really can’t achieve great things in the high-profile environment in which we work.” During the 1990s, Skanska entered an expansive growth phase. A string of successful acquisitions paved the way for the company’s transformation into a global enterprise. “Today the company’s focus is on profitable growth,” continues Crane. “But you can’t really achieve growth unless you are doing a very good job of developing your people and having the right people in the right places and driving a culture of growth.” In the United States alone, Skanska has more than 8,000 employees in four distinct business units: Skanska USA Building, also known as the Construction Manager, builds everything at ground level and above—hospitals, educational facilities, stadiums, airport terminals, and other massive projects. Skanska USA Civil does everything at ground level and below, such as light rail, water treatment facilities, power plants or power industry facilities, highways, and bridges. Skanska Infrastructure Development develops public-private partnerships—projects in which Skanska adds equity and also arranges for outside financing. Skanska Commercial Development acts like a commercial real estate developer, acquiring land and building offices on spec or build-to-suit for its clients. Skanska's international portfolio includes construction of the new Meadowlands Stadium. Getting the various units to operate collaboratatively helps Skanska deliver high value to clients and shareholders. “When we have this collaboration among units, it allows us to enrich each of the business units and, at the same time, develop our future leaders to be more facile in operating across business units—more accepting of a ‘one Skanska’ approach,” explains Crane. Workforce Worldwide But HR needs processes and tools to support managers who face such business dynamics. Oracle Talent Management Cloud is helping Skanska implement world-class recruiting strategies and generate the insights needed to drive quality hiring practices, internal mobility, and a proactive approach to building talent pipelines. With their new cloud system in place, Skanska HR leaders can manage everything from recruiting, compensation, and goal and performance management to employee learning and talent review—all as part of a single, cohesive software-as-a-service (SaaS) environment. Skanska has successfully implemented two modules from Oracle Talent Management Cloud—the recruiting and performance management modules—and is in the process of implementing the learn module. Internally, they call the systems Skanska Recruit, Skanska Talent, and Skanska Learn. The timing is apropos. With high rates of unemployment in recent years, there have been many job candidates on the market. However, talent scarcity continues to frustrate recruiters. Oracle Taleo Recruiting Cloud Service, one of the applications in the Oracle Talent Management cloud portfolio, enables Skanska managers to create more-intelligent recruiting strategies, pulling high-performer profile statistics to create new candidate profiles and using multitiered screening and assessments to ensure that only the best-suited candidate applications make it to the recruiter’s desk. Tools such as applicant tracking, interview management, and requisition management help recruiters and hiring managers streamline the hiring process. Oracle’s cloud-based software system automates and streamlines many other HR processes for Skanska’s multinational organization and delivers insight into the success of recruiting and talent-management efforts. “The Oracle system is definitely helping us to construct global HR processes,” adds Bjork. “It is really important that we have a business model that is decentralized, so we can effectively serve our local markets, and interact with our global ERP [enterprise resource planning] systems as well. We would not be able to do this without a really good, well-integrated HCM system that could support these efforts.” A key piece of this effort is something Skanska has developed internally called the Skanska Leadership Profile. Core competencies, on which all employees are measured, are used in performance reviews to determine weak areas but also to discover talent, such as those who will be promoted or need succession plans. This global profiling system brings consistency to the way HR professionals evaluate and review talent across the company, with a consistent set of ratings and a consistent definition of competencies. All salaried employees in Skanska are tied to a talent management process that gives opportunity for midyear and year-end reviews. Using the performance management module, managers can align individual goals with corporate goals; provide clear visibility into how each employee contributes to the success of the organization; and drive a strategic, end-to-end talent management strategy with a single, integrated system for all talent-related activities. This is critical to a company that is highly focused on ensuring that every employee has a development plan linked to his or her succession potential. “Our approach all along has been to deploy software applications that are seamless to end users,” says Crane. “The beauty of a cloud-based system is that much of the functionality takes place behind the scenes so we can focus on making sure users can access the data when they need it. This model greatly improves their efficiency.” The employee profile not only sets a competency baseline for new employees but is also integrated with Skanska’s other back-office Oracle systems to ensure consistency in the way information is used to support other business functions. “Since we have about a dozen different HR systems that are providing us with information, we built a master database that collects all the information,” explains Lindholm. “That data is sent not only to Oracle Talent Management Cloud, but also to other systems that are dependent on this information.” Collaboration to Scale Skanska is poised to launch a new Oracle module to link employee learning plans to the review process and recruitment assessments. According to Crane, connecting these processes allows Skanska managers to see employees’ progress and produce an updated learning program. For example, as employees take classes, supervisors can consult the Oracle Talent Management Cloud portal to monitor progress and align it to each individual’s training and development plan. “That’s a pretty compelling solution for an organization that wants to manage its talent on a real-time basis and see how the training is working,” Crane says. Rolling out Oracle Talent Management Cloud was a joint effort among HR, IT, and a global group that oversaw the worldwide implementation. Skanska deployed the solution quickly across all markets at once. In the United States, for example, more than 35 offices quickly got up to speed on the new system via webinars for employees and face-to-face training for the HR group. “With any migration, there are moments when you hold your breath, but in this case, we had very few problems getting the system up and running,” says Crane. Lindholm adds, “There has been very little resistance to the system as users recognize its potential. Customizations are easy, and a lasting partnership has developed between Skanska and Oracle when help is needed. They listen to us.” Bjork elaborates on the implementation process from an IT perspective. “Deploying a SaaS system removes a lot of the complexity,” he says. “You can downsize the IT part and focus on the business part, which increases the probability of a successful implementation. If you want to scale the system, you make a quick phone call. That’s all it took recently when we added 4,000 users. We didn’t have to think about resizing the servers or hiring more IT people. Oracle does that for us, and they have provided very good support.” As a result, Skanska has been able to implement a single, cost-effective talent management solution across the organization to support its strategy to recruit and develop a world-class staff. Stakeholders are confident that they are providing the most efficient recruitment system possible for competent personnel at all levels within the company—from skilled workers at construction sites to top management at headquarters. And Skanska can retain skilled employees and ensure that they receive the development opportunities they need to grow and advance.

    One of the biggest IT challenges facing today’s health care industry is the difficulty finding reliable, secure, and cost-effective ways to exchange information. Payers and providers need versatile platforms for enterprise-wide information sharing. Clinicians require accurate information to provide quality care to patients while administrators need integrated information for all facets of the business operation. Both sides of the organization must be able to access information from research and development systems, practice management systems, claims systems, financial systems, and many others. Externally, these organizations must share claims data, patient records, pharmaceutical data, lab reports, and diagnostic information among third party entities—all while complying with emerging standards for formatting, processing, and storing electronic health records (EHR). Service-oriented architecture (SOA) enables developers to integrate many types of software applications, databases and computing platforms within a particular health network as well as with community, state, and national health information exchanges. The Oracle SOA Suite for healthcare integration is designed to provide healthcare organizations with comprehensive integration capabilities within a unified middleware platform, as well as with healthcare libraries and templates for streamlining healthcare IT projects. It reduces the need for specialized skills and enforces an enterprise-wide view of critical healthcare data.  Here is a new white paper that details more about this offering: Oracle SOA Suite for Healthcare Integration

  • HTG Explains: Which Linux File System Should You Choose?

    - by Justin Garrison
    File systems are one of the layers beneath your operating system that you don’t think about—unless you’re faced with the plethora of options in Linux. Here’s how to make an educated decision on which file system to use. The landscape of the Linux file system support is drastically different from Windows and OS X. In Windows and OS X you can find software that will add support for non-standard file systems, but both operating systems can only be installed on their native file system and third party support is added after the fact. Linux on the other hand has a vast array of supported file systems built into the kernel. But how are you supposed to know which file system to pick when installing? We will take a look at some of the most popular choices available and give you use cases to consider—the choice is ultimately up to you based on your needs.

  • How to go from Mainframe to the Cloud?

    - by Ruma Sanyal
    Running applications on IBM mainframes is expensive, complex, and hinders IT responsiveness. The high costs from frequent forced upgrades, long integration cycles, and complex operations infrastructures can only be alleviated by migrating away from a mainframe environment.  Further, data centers are planning for cloud enablement pinned on principles of operating at significantly lower cost, very low upfront investment, operating on commodity hardware and open, standards based systems, and decoupling of hardware, infrastructure software, and business applications. These operating principles are in direct contrast with the principles of operating businesses on mainframes. By utilizing technologies such as Oracle Tuxedo, Oracle Coherence, and Oracle GoldenGate, businesses are able to quickly and safely migrate away from their IBM mainframe environments. Further, running Oracle Tuxedo and Oracle Coherence on Oracle Exalogic, the first and only integrated cloud machine on the market, Oracle customers can not only run their applications on standards-based open systems, significantly cutting their time to market and costs, they can start their journey of cloud enabling their mainframe applications. Oracle Tuxedo re-hosting tools and techniques can provide automated migration coverage for more than 95% of mainframe application assets, at a fraction of the cost Oracle GoldenGate can migrate data from mainframe systems to open systems, eliminating risks associated with the data migration Oracle Coherence hosts transactional data in memory providing mainframe-like data performance and linear scalability Running Oracle software on top of Oracle Exalogic empowers customers to start their journey of cloud enabling their mainframe applications Join us in a series of events across the globe where you you'll learn how you can build your enterprise cloud and add tremendous value to your business. In addition, meet with Oracle experts and your peers to discuss best practices and see how successful organizations are lowering total cost of ownership and achieving rapid returns by moving to the cloud.

  • CMS and Databases vs. DIY

    - by hozza
    I have been programming for many years now, primarily in PHP and the like and would consider myself an intermediate programmer. Some of my online projects have now gone global and very widely used, i am now in deep thought about scalability etc. All of my systems so far are written in PHP, no known database structure such as MySQL etc. Instead our databases use an 'operating system style' method of storing information, files and folders if you will. We also do not use any outside/third-party software or CMS, so far this has work out extremely well. Most people, when they hear about the way we do things, criticize and say that is an idiotic idea but normally after seeing our systems in more dept are converted to our way of doing things. Is it really that bad to not use a standard databasing systems and only using the one (slightly heavier than others) language of PHP? How well on the face of it will this kind of setup scale? N.B. Our systems include things such as account and user management, documentation development and task/project managing.

  • is Java free for mobile development?

    - by exTrace101
    Q1. I would like to know if it's free for a developer (I mean, if I have to pay no royalties to Sun/Oracle) to develop (Android) mobile apps in Java? After reading this snippet about use of Java field, I'm getting the impression that Java is not free for mobile development, is that right? .."General Purpose Desktop Computers and Servers" means computers, including desktop and laptop computers, or servers, used for general computing functions under end user control (such as but not specifically limited to email, general purpose Internet browsing, and office suite productivity tools). The use of Software in systems and solutions that provide dedicated functionality (other than as mentioned above) or designed for use in embedded or function-specific software applications, for example but not limited to: Software embedded in or bundled with industrial control systems, wireless mobile telephones, wireless handheld devices, netbooks, kiosks, TV/STB, Blu-ray Disc devices, telematics and network control switching equipment, printers and storage management systems, and other related systems are excluded from this definition and not licensed under this Agreement... and from http://www.excelsiorjet.com/embedded/ Notice : The Java SE Embedded technology license currently prohibits the use of Java SE in cell phones. Q2. how come these plethora of Android Java developers aren't paying Sun/Oracle a dime?

  • New whitepaper: Evolution from the Traditional Data Center to Exalogic: An Operational Perspective

    - by Javier Puerta
    IT organizations are struggling with the need to balance the day-to-day concerns of data center management against the business level requirements to deliver long-term value. This balancing act has proven difficult and inefficient: systems and application management tools are resource intensive and traditional infrastructure management architectures have developed over time on a project by project basis. These traditional management systems consist of multiple tools that require administrators to waste time performing too many steps to handle routine administrative tasks. Operational efficiency and agility in your enterprise are directly linked to the capabilities provided by the management layer across the entire stack, from the application, middleware, operating system, compute, network and storage. Only when this end to end capability is provided will we experience the full benefit of a scalable, efficient, responsive and secure datacenter. Managing Exalogic is substantially less complex and error prone than managing traditional systems built from individually sourced, multi-vendor components because Exalogic is designed to be administered and maintained as a single, integrated system (Figure 1). It is at the forefront of the industry-wide shift away from costly and inferior one-off platforms toward private clouds and Engineered Systems.

  • Book / software to learn ERP?

    - by user22311
    For a while I've been wanting to learn ERP. What I would like to do is set up a system, and then practice running a business doing things like generating invoices, raising purchase orders, producing monthly accounts, keeping track of fixed assets etc. Then look at enhancing the system further by adding custom code. I know there are a variety of open source ERP systems around, but really I would prefer a widely used commercial system as having familiarity with such a system would be more marketable. So are there any such systems that have a free developer version available? I've looked around, but I've had trouble finding such a system. Also I would like to find a good book or more likely books to read on ERP. Ideally I would be able to get an indepth explanation ERP from a business perspective, ie the accounting operations it supports, how to do all the regular accounting tasks, configuration, business operations best practices, accounting controls and so on. In addition I would like an IT perspective, ie setting up the system, developing forms and reports. Unfortunately the few books I've looked at have been really superficial and totally inadequate. They either fall into the beginning programmer camp, where they use the programming tools but concentrate on programming 101 topics like loops, flow control etc. Or they cover setting up the system with lots of screen shots, but little substance as to why things should be done a certain way. I have a programming background but no real experience in implementing ERP systems. Also I have a reasonable accounting knowledge, and have used ERP systems in various jobs, but only to a very limited degree. So are there any ERP experts who can point me in the right direction? Thanks.

  • Issue 15: The Benefits of Oracle Exastack

    - by rituchhibber
         SOLUTIONS FOCUS The Benefits of Oracle Exastack Paul ThompsonDirector, Alliances and Solutions Partner ProgramsOracle EMEA Alliances & Channels RESOURCES -- Oracle PartnerNetwork (OPN) Oracle Exastack Program Oracle Exastack Ready Oracle Exastack Optimized Oracle Exastack Labs and Enablement Resources Oracle Exastack Labs Video Tour SUBSCRIBE FEEDBACK PREVIOUS ISSUES Exastack is a revolutionary programme supporting Oracle independent software vendor partners across the entire Oracle technology stack. Oracle's core strategy is to engineer software and hardware together, and our ISV strategy is the same. At Oracle we design engineered systems that are pre-integrated to reduce the cost and complexity of IT infrastructures while increasing productivity and performance. Oracle innovates and optimises performance at every layer of the stack to simplify business operations, drive down costs and accelerate business innovation. Our engineered systems are optimised to achieve enterprise performance levels that are unmatched in the industry. Faster time to production is achieved by implementing pre-engineered and pre-assembled hardware and software bundles. Our strategy of delivering a single-vendor stack simplifies and reduces costs associated with purchasing, deploying, and supporting IT environments for our customers and partners. In parallel to this core engineered systems strategy, the Oracle Exastack Program enables our Oracle ISV partners to leverage a scalable, integrated infrastructure that delivers their applications tuned, tested and optimised for high-performance. Specifically, the Oracle Exastack Program helps ISVs run their solutions on the Oracle Exadata Database Machine, Oracle Exalogic Elastic Cloud, and Oracle SPARC SuperCluster T4-4 - integrated systems products in which the software and hardware are engineered to work together. These products provide OPN members with a lower cost and high performance infrastructure for database and application workloads across on-premise and cloud based environments. Ready and Optimized Oracle Partners can now leverage our new Oracle Exastack Program to become Oracle Exastack Ready and Oracle Exastack Optimized. Partners can achieve Oracle Exastack Ready status through their support for Oracle Solaris, Oracle Linux, Oracle VM, Oracle Database, Oracle WebLogic Server, Oracle Exadata Database Machine, Oracle Exalogic Elastic Cloud, and Oracle SPARC SuperCluster T4-4. By doing this, partners can demonstrate to their customers that their applications are available on the latest major releases of these products. The Oracle Exastack Ready programme helps customers readily differentiate Oracle partners from lesser software developers, and identify applications that support Oracle engineered systems. Achieving Oracle Exastack Optimized status demonstrates that an OPN member has proven itself against goals for performance and scalability on Oracle integrated systems. This status enables end customers to readily identify Oracle partners that have tested and tuned their solutions for optimum performance on an Oracle Exadata Database Machine, Oracle Exalogic Elastic Cloud, and Oracle SPARC SuperCluster T4-4. These ISVs can display the Oracle Exadata Optimized, Oracle Exalogic Optimized or Oracle SPARC SuperCluster Optimized logos on websites and on all their collateral to show that they have tested and tuned their application for optimum performance. Deliver higher value to customers Oracle's investment in engineered systems enables ISV partners to deliver higher value to customer business processes. New innovations are enabled through extreme performance unachievable through traditional best-of-breed multi-vendor server/software approaches. Core product requirements can be launched faster, enabling ISVs to focus research and development investment on core competencies in order to bring value to market as quickly as possible. Through Exastack, partners no longer have to worry about the underlying product stack, which allows greater focus on the development of intellectual property above the stack. Partners are not burdened by platform issues and can concentrate simply on furthering their applications. The advantage to end customers is that partners can focus all efforts on business functionality, rather than bullet-proofing underlying technologies, and so will inevitably deliver application updates faster. Exastack provides ISVs with a number of flexible deployment options, such as on-premise or Cloud, while maintaining one single code base for applications regardless of customer deployment preference. Customers buying their solutions from Exastack ISVs can therefore be confident in deploying on their own networks, on private clouds or into a public cloud. The underlying platform will support all conceivable deployments, enabling a focus on the ISV's application itself that wouldn't be possible with other vendor partners. It stands to reason that Exastack accelerates time to value as well as lowering implementation costs all round. There is a big competitive advantage in partners being able to offer customers an optimised, pre-configured solution rather than an assortment of components and a suggested fit. Once a customer has decided to buy an Oracle Exastack Ready or Optimized partner solution, it will be up and running without any need for the customer to conduct testing of its own. Operational costs and complexity are also reduced, thanks to streamlined customer support through standardised configurations and pro-active monitoring. 'Engineered to Work Together' is a significant statement of Oracle strategy. It guarantees smoother deployment of a single vendor solution, clear ownership with no finger-pointing and the peace of mind of the Oracle Support Centre underpinning the entire product stack. Next steps Every OPN member with packaged applications must seriously consider taking steps to become Exastack Ready, or Exastack Optimized at the first opportunity. That first step down the track is to talk to an expert on the OPN Portal, at the Oracle Partner Business Center or to discuss the next steps with the closest Oracle account manager. Oracle Exastack lab environments and other technical enablement resources are available for OPN members wishing to further their knowledge of Oracle Exastack and qualify their applications for Oracle Exastack Optimized. New Boot Camps and Guided Learning Paths (GLPs), tailored specifically for ISVs, are available for Oracle Exadata Database Machine, Oracle Exalogic Elastic Cloud, Oracle Linux, Oracle Solaris, Oracle Database, and Oracle WebLogic Server. More information about these GLPs and Boot Camps (including delivery dates and locations) are posted on the OPN Competency Center and corresponding OPN Knowledge Zones.

  • A Guided Tour of Complexity

    - by JoshReuben
    I just re-read Complexity – A Guided Tour by Melanie Mitchell , protégé of Douglas Hofstadter ( author of “Gödel, Escher, Bach”) http://www.amazon.com/Complexity-Guided-Tour-Melanie-Mitchell/dp/0199798109/ref=sr_1_1?ie=UTF8&qid=1339744329&sr=8-1 here are some notes and links:   Evolved from Cybernetics, General Systems Theory, Synergetics some interesting transdisciplinary fields to investigate: Chaos Theory - http://en.wikipedia.org/wiki/Chaos_theory – small differences in initial conditions (such as those due to rounding errors in numerical computation) yield widely diverging outcomes for chaotic systems, rendering long-term prediction impossible. System Dynamics / Cybernetics - http://en.wikipedia.org/wiki/System_Dynamics – study of how feedback changes system behavior Network Theory - http://en.wikipedia.org/wiki/Network_theory – leverage Graph Theory to analyze symmetric  / asymmetric relations between discrete objects Algebraic Topology - http://en.wikipedia.org/wiki/Algebraic_topology – leverage abstract algebra to analyze topological spaces There are limits to deterministic systems & to computation. Chaos Theory definitely applies to training an ANN (artificial neural network) – different weights will emerge depending upon the random selection of the training set. In recursive Non-Linear systems http://en.wikipedia.org/wiki/Nonlinear_system – output is not directly inferable from input. E.g. a Logistic map: Xt+1 = R Xt(1-Xt) Different types of bifurcations, attractor states and oscillations may occur – e.g. a Lorenz Attractor http://en.wikipedia.org/wiki/Lorenz_system Feigenbaum Constants http://en.wikipedia.org/wiki/Feigenbaum_constants express ratios in a bifurcation diagram for a non-linear map – the convergent limit of R (the rate of period-doubling bifurcations) is 4.6692016 Maxwell’s Demon - http://en.wikipedia.org/wiki/Maxwell%27s_demon - the Second Law of Thermodynamics has only a statistical certainty – the universe (and thus information) tends towards entropy. While any computation can theoretically be done without expending energy, with finite memory, the act of erasing memory is permanent and increases entropy. Life & thought is a counter-example to the universe’s tendency towards entropy. Leo Szilard and later Claude Shannon came up with the Information Theory of Entropy - http://en.wikipedia.org/wiki/Entropy_(information_theory) whereby Shannon entropy quantifies the expected value of a message’s information in bits in order to determine channel capacity and leverage Coding Theory (compression analysis). Ludwig Boltzmann came up with Statistical Mechanics - http://en.wikipedia.org/wiki/Statistical_mechanics – whereby our Newtonian perception of continuous reality is a probabilistic and statistical aggregate of many discrete quantum microstates. This is relevant for Quantum Information Theory http://en.wikipedia.org/wiki/Quantum_information and the Physics of Information - http://en.wikipedia.org/wiki/Physical_information. Hilbert’s Problems http://en.wikipedia.org/wiki/Hilbert's_problems pondered whether mathematics is complete, consistent, and decidable (the Decision Problem – http://en.wikipedia.org/wiki/Entscheidungsproblem – is there always an algorithm that can determine whether a statement is true).  Godel’s Incompleteness Theorems http://en.wikipedia.org/wiki/G%C3%B6del's_incompleteness_theorems  proved that mathematics cannot be both complete and consistent (e.g. “This statement is not provable”). Turing through the use of Turing Machines (http://en.wikipedia.org/wiki/Turing_machine symbol processors that can prove mathematical statements) and Universal Turing Machines (http://en.wikipedia.org/wiki/Universal_Turing_machine Turing Machines that can emulate other any Turing Machine via accepting programs as well as data as input symbols) that computation is limited by demonstrating the Halting Problem http://en.wikipedia.org/wiki/Halting_problem (is is not possible to know when a program will complete – you cannot build an infinite loop detector). You may be used to thinking of 1 / 2 / 3 dimensional systems, but Fractal http://en.wikipedia.org/wiki/Fractal systems are defined by self-similarity & have non-integer Hausdorff Dimensions !!!  http://en.wikipedia.org/wiki/List_of_fractals_by_Hausdorff_dimension – the fractal dimension quantifies the number of copies of a self similar object at each level of detail – eg Koch Snowflake - http://en.wikipedia.org/wiki/Koch_snowflake Definitions of complexity: size, Shannon entropy, Algorithmic Information Content (http://en.wikipedia.org/wiki/Algorithmic_information_theory - size of shortest program that can generate a description of an object) Logical depth (amount of info processed), thermodynamic depth (resources required). Complexity is statistical and fractal. John Von Neumann’s other machine was the Self-Reproducing Automaton http://en.wikipedia.org/wiki/Self-replicating_machine  . Cellular Automata http://en.wikipedia.org/wiki/Cellular_automaton are alternative form of Universal Turing machine to traditional Von Neumann machines where grid cells are locally synchronized with their neighbors according to a rule. Conway’s Game of Life http://en.wikipedia.org/wiki/Conway's_Game_of_Life demonstrates various emergent constructs such as “Glider Guns” and “Spaceships”. Cellular Automatons are not practical because logical ops require a large number of cells – wasteful & inefficient. There are no compilers or general program languages available for Cellular Automatons (as far as I am aware). Random Boolean Networks http://en.wikipedia.org/wiki/Boolean_network are extensions of cellular automata where nodes are connected at random (not to spatial neighbors) and each node has its own rule –> they demonstrate the emergence of complex  & self organized behavior. Stephen Wolfram’s (creator of Mathematica, so give him the benefit of the doubt) New Kind of Science http://en.wikipedia.org/wiki/A_New_Kind_of_Science proposes the universe may be a discrete Finite State Automata http://en.wikipedia.org/wiki/Finite-state_machine whereby reality emerges from simple rules. I am 2/3 through this book. It is feasible that the universe is quantum discrete at the plank scale and that it computes itself – Digital Physics: http://en.wikipedia.org/wiki/Digital_physics – a simulated reality? Anyway, all behavior is supposedly derived from simple algorithmic rules & falls into 4 patterns: uniform , nested / cyclical, random (Rule 30 http://en.wikipedia.org/wiki/Rule_30) & mixed (Rule 110 - http://en.wikipedia.org/wiki/Rule_110 localized structures – it is this that is interesting). interaction between colliding propagating signal inputs is then information processing. Wolfram proposes the Principle of Computational Equivalence - http://mathworld.wolfram.com/PrincipleofComputationalEquivalence.html - all processes that are not obviously simple can be viewed as computations of equivalent sophistication. Meaning in information may emerge from analogy & conceptual slippages – see the CopyCat program: http://cognitrn.psych.indiana.edu/rgoldsto/courses/concepts/copycat.pdf Scale Free Networks http://en.wikipedia.org/wiki/Scale-free_network have a distribution governed by a Power Law (http://en.wikipedia.org/wiki/Power_law - much more common than Normal Distribution). They are characterized by hubs (resilience to random deletion of nodes), heterogeneity of degree values, self similarity, & small world structure. They grow via preferential attachment http://en.wikipedia.org/wiki/Preferential_attachment – tipping points triggered by positive feedback loops. 2 theories of cascading system failures in complex systems are Self-Organized Criticality http://en.wikipedia.org/wiki/Self-organized_criticality and Highly Optimized Tolerance http://en.wikipedia.org/wiki/Highly_optimized_tolerance. Computational Mechanics http://en.wikipedia.org/wiki/Computational_mechanics – use of computational methods to study phenomena governed by the principles of mechanics. This book is a great intuition pump, but does not cover the more mathematical subject of Computational Complexity Theory – http://en.wikipedia.org/wiki/Computational_complexity_theory I am currently reading this book on this subject: http://www.amazon.com/Computational-Complexity-Christos-H-Papadimitriou/dp/0201530821/ref=pd_sim_b_1   stay tuned for that review!
