“Upgrading from MySQL 5.0 to MySQL 5.5 Introduces a New Database Format” in the OES 11 SP2:
WebServices and Applications Guide.
MySQL is installed on all nodes where you want it to run, but a database runs on only one node in the cluster at a time. The MySQL configuration files are modified on each node to point to a path on a Linux Logical Volume Manager (LVM) volume group cluster resource that contains the MySQL database files. You cluster‐enable the volume group by using the MySQL template, then configure its resource load, unload, and monitoring scripts, set its resource failover and failback modes, and assign the resource to specific nodes in the cluster. When a node fails where the resource is online, the resource fails over to the next preferred node in the cluster.
1.2 OES Components That Provide WebServices and Applications
OES comes bundled with all of the WebServices and Applications components you need to host dynamic web content and deploy webapplications that you can either build yourself or download from the World Wide Web. Some of these components are developed by the open source software community, while others are developed by Novell. Each component offers an important building block that lets you build the solutions that best meet your business needs.
Information and communication technologies are designed to support and anticipate the con- tinuing changes of the information society, while outlining new economic, social and cultural dimensions. We see the growth of new business models whose aim is to remove traditional barriers and improve the value of goods and services. Information is a strategic resource and its manipulation raises new problems for all entities involved in the process. Information and communication technologies should be a stable support in managing the flow of data and support the integrity, confidentiality and availability. Concepts such as eBusiness, eCommerce, Software as a Service, Cloud Computing and Social Media are based on web technologies consisting of complex languages, protocols and standards, built around client- server architecture. One of the most used technologies in mobile applications are the WebServices defined as an application model supported by any operating system able to provide certain functionalities using Internet technologies to promote interoperability between vari- ous applications and platforms. Webservices use HTTP, XML, SSL, SMTP and SOAP, be- cause their stability has proven over the years. Their functionalities are highly variable, with Webservicesapplications exchange type, weather, arithmetic or authentication services. In this article we will talk about SOAP and REST architectures for webservices in mobile appli- cations and we will also provide some practical examples based on Android platform.
One of my previous papers discussed host-level footprinting to find applications pointing to specific IP addresses [ http://www.infosecwriters.com/texts.php?op=display&id=259 ]. This paper focuses on domain footprinting and discusses a complete approach to identify and footprint all possible domains running webapplications or webservices.
1 Different books and different organizations provide different definitions to WebServices. Some of them are listed here.
A web service is any piece of software that makes itself available over the internet and uses a standardized XML messaging system. XML is used to encode all communications to a web service. For example, a client invokes a web service by sending an XML message, then waits for a corresponding XML response. As all communication is in XML, webservices are not tied to any one operating system or programming language—Java can talk with Perl; Windows applications can talk with Unix applications.
Key words: threat analysis – webservices – webapplications
Analyzing and modelling the potential threats that an application faces is an important step in the process of designing a secure application. Some of these threats are by nature very specific to the application, and one can only give quite general guidelines on how to identify such threats. But other threats are directly or indirectly related to the underlying platforms, technologies or programming languages. Hence, it makes sense to identify and document these technology-specific threats, and to provide guidelines to software vendors on how to mitigate the associated risks.
invocations, however, the negotiation itself causes a considerable overhead.
2.4. Requirements Summary
As an interim result, it seems that there is no perfect combination of traditional and alternative technologies, but that the use of a specific approach is determined by the capabilities of the mobile system and its applications. Although webservices have originally been intended to integrate heterogeneous resources, the diversification of protocols resulting from necessary adaptations leads to another integration problem. On the one hand, heterogeneous capabilities and characteristics of mobile devices with respect to network connection and protocol support have to be considered. On the other hand, interoperability with traditional applications and industry standards should be preserved. Finally, dynamic applications such as ad-hoc mobile business processes require the executing mobile device to adapt to available service instances and protocols at runtime – a system software characteristic which is hardly supported by current mobile web service architectures.
• WebServices have become the dominant standard that allow applications written by different organizations or entities to interact with one another. WebServices are heavily used for both intra and inter organizational communications. This session explores several approaches that can be used to extend IDMS applications, allowing them to consume and offer webservices.
VE takes a different slice at reducing complexity. VE’s sweet spot is building n-tier applications and Webservices that take full advantage of the J2EE architecture, similar to WSAD. However, to reduce complexity, VE provides an IDE (VE/Designer) that layers on top of a framework for representing business logic in its basic form as objects, processes, and rules, yet completely independent of J2EE or any of the involved technologies. VE/Designer uses UML to capture the business logic, and XML to store it. VE/Server, which runs on any J2EE server, loads the application logic from XML files into fully functional J2EE components that are ready to test and execute. No code generation, nor the need to understand or manipulate the generated code.
This client may also run in a Web server and generate an HTML display, but this is not required.
Science Applications as Services
While it is certainly possible to develop WebServices versions of every subroutine in Numerical Recipes and to rewrite all existing science applications so that they expose their functions and subroutines as services for remote components, we present a simple alternative approach that can be used to treat an entire existing application as a service.

Depending on the technique used in the capture of requirements, it is possible to obtain innovative and iterative processes that truly support the construction of applications that consume webservices. In the present article the elicitation approaches of the agile and traditional software methodologies are analyzed and the aspects of the rules that guarantee the con- cordance with the characteristics of the applications that consume services are taken, with the purpose of proposing a framework of work for the elicitation of the information applied to the specific case of appli- cations that use webservices. At the end of the article, a validation will be carried out in two companies that provide software development services.
With the proliferation of the Internet, companies are increasingly leveraging the Internet to achieve competitive advantage. For example, an interactive Web site was developed and used to disseminate bid packages to contractors and material suppliers at different locations (Runser et al. 2002). Construction projects are often performed and managed in a geographically distributed fashion, where a company’s headquarter, the regional offices and the construction sites are located in different cities, states and countries. Each office may run its own in-house applications. Integrating software applications as Webservices can potentially remove the barriers of geographic boundaries and expedite project delivery. An integration framework would require not only data integration but also network communication in order to achieve interoperability. In this paper, we describe a prototype infrastructure to integrate project management applications as Webservices.
in the Forms module, we need to migrate it to the database and expose it from there. Let us explore a bit more this idea of migrating the business logic.
4.1. Why moving Forms business logic to the DB?
Forms architecture is not making a clear separation between its visual and data components. In ADF, for instance, the Data Modeler (e.g. ADF Business Components (BC)) cannot refer objects defined in the Viewer layer. In Forms any program unit or trigger can refer visual components. Forms is offering therefore a greater flexibility in application development, while in ADF the not-so-flexible structure is compensated with greater degree of reuse: the functionality defined in ADF BC can be exposed as Webservices and called from external applications. The only possibility we have to increase the degree of reusability in Forms applications is re-writing or separating the data manipulating business logic from the user interface one. After all, the business processes should not depend on the currently chosen user interface.
We found it important to think of WS- BusinessActivity as a set of related protocol elements, or a toolkit for terminating pair-wise stateful interactions, rather than as a single monolithic protocol. Not all possible paths defined in the WS-BusinessActivity specification need to be used in any one application protocol  and the system designer is free to use only those paths that are appropriate for their purposes. We initially found that it was very difficult to define correct application protocols, even for what seemed like relatively simple examples, as race situations were not being properly handled. However, once we adopted WS- BusinessActivity, and gained some experience, the task of designing correct contracts and application protocols became much easier.
The AsynchHandler interface contains the handleResponse(Response) method that is called after the run time has received and processed the asynchronous response from the server. The response is delivered to the callback handler in the form of a javax.xml.ws.Response object. The response object returns the response content when the get method is called. Additionally, if an error was received, an exception is returned to the client during that call. The response method is then invoked according to the threading model used by the executor method, java.util.concurrent.Executor , on the client’s java.xml.ws.Service instance that was used to create the dynamic proxy or dispatch client instance. The executor is used to invoke any asynchronous callbacks registered by the application. Use the setExecutor and getExecutor methods to modify and retrieve the executor configured for the service. To create an asynchronous web service client using the callback model, follow these steps: 1. Create the callback handler class RetrieveCustomerCallbackHandler in the
Caprylins are esters of glycerol and caprylic acid that find applications in food, pharmaceutical and cosmetic fields. They have low melting points (10 o C – 30 o C), high boiling points (233 o C – 395 o C), octanol-water partitioning coefficient (Log P) higher than 1.9, being insoluble in water and soluble in organic solvents such as n-hexane and chloroform. Several studies indicate a positive role played by caprylins on the human metabolism – as an alternative to long chain fatty acid lipids- due their low accumulation in adipose tissue, easy intracellular oxidation and high formation of ketone bodies. Therefore, they may be useful for patients that present neurological disorders and/or dietary requirements. Monocaprylin and dicaprylin are considered GRAS emulsifiers (Generally Recognized as Safe) by FDA, being largely applied on foods with no major concerns. They also can act as antimicrobial agents for food conservation purposes. There are several manufacturing processes applicable to caprylins, including the direct esterification of glycerol and caprylic acid catalyzed by immobilized lipase, method that has been receiving special attention during the last two decades. Caprylins can be identified and/or quantified through several analytical techniques (including titration by sodium hydroxide, gas and liquid chromatography coupled to a variety of detection methods, thin layer chromatography and differential scanning calorimetry Despite the existing information on caprylins, the amount of scientific material available about these compounds is much lower than the observed on the long chain glycerides. The development of more efficient manufacturing methods, lowering the production costs and increasing market availability, plays a key role for encouraging further research on clinical, pharmaceutical and technological applications.
The biggest question of WS-* services relevancy right now is the relevancy of XML as a payload format. JSON has become more popular over time, and more contenders like YAML have also appeared. What does a verbose format like XML could offer that its counterpart lack? In the future, a web service that offers the same qualities as SOAP but uses JSON could easily mean that SOAP is no longer more than a relic from the past of web development.
kako bi ga druge osobe ili kompanije mogle koristiti. 
Koncept Web servisa sve više raste i razvija se novi uzbudljivi model poslovanja. Sada je slučaj da koncept Web servisa eksplodira na nova područja i proširuje svoje mogućnosti. Osnovni cilj Web servisa koji je na visokoj razini je da se unaprijedi distribuirano računalstvo (gdje je logika aplikacije razdvojena u male logičke dijelove i radi na više računala ili uređaja). Praktični razlog za izgradnju Web servisa je omogućiti kompanijama da izgrade male, ponovno iskoristive i samo opisujuće metode koje mogu i drugi koristiti. Web servis sam po sebi je dio kôda koji može biti pozvan od strane druge aplikacije ili udaljenog procesa. Međutim ako bi programer u bliskoj budućnosti mogao spojiti zajedno dovoljan broj Web servisa on bi mogao implementirati većinu značajki potrebnih za podršku cijeloj Web aplikaciji. Praktični cilj Web servisa je da se kompanijama omogući da svoje poslovanje koncentriraju samo na potrebe svoje osnovne djelatnosti te da pozivaju Web servise kako bi nadopunili svoje osnovne djelatnosti. 
I “A Web Service is a software system designed to support interoperable machine-to-machine interaction over a network. It has an interface described in a machine-processable format (specifically WSDL). Other systems interact with the Web Service in a manner prescribed by its description using SOAP messages, typically conveyed using HTTP with an XML serialization in conjunction with other Web-related standards.” (W3C)
