Presentation delivered by Mike Croft and Steve Millidge at DOAG German Oracle User Group Conference in Nuremberg, 19-21 November 2013. Mobile devices get more and more powerful, JEE servers get faster and smaller. This convergence means it is now possible to run GlassFish 4 on a phone platform. In this session we'll show you how to get GlassFish up and running on Ubuntu Touch and communicating with a back end GlassFish server cluster to enable you to combine full JEE on client device and server. The presentation will be mainly live demo of using GlassFish 4 on a phone communicating with a cluster of GlassFish servers in Amazon EC2.There will be slides to talk through the demo architecture and code snippets showing the latest JEE7 websocket apis being used to communicate device to server. We will first install Java and GlassFish on the phone. We will then demonstrate developing a quick HTML 5 JEE web application to retrieve data from a GlassFish cluster using WebSockets. We'll deploy this to the phone and demonstrate it running on Ubuntu Touch.

Infinispan isn't just a scalable key/value grid platform: it simplifies execution of distributed query tasks in Map/Reduce style, and it integrates a powerful indexing engine to run full-text searches and efficiently extract information from your largest data collections. Infinispan's search engine is built around on Apache Lucene and directly exposes the Lucene API to its users to build powerful search applications which run on data sets residing in-memory. In this talk Navin - author of the Infinispan Query module - will demonstrate how you can leverage the strength of full-text queries to efficiently perform searches on your data.

Slides by Matt Brasier, Principal Consultant at C2B2, from the Hands on Lab delivered at the JavaOne 2014 conference. ABOUT HOL: This session will demonstrate the depth and breadth of the information available via the JMX API. We will tools that come with the JDK to peer deep into the workings of the JVM and understand how to identify and solve common performance bottlenecks or other problems. Attendees will get examples of using tools like VisualVM and Jstat to interrogate the JVM, and how to interpret the data returned, and learn how to add JMX instrumentation to their own applications and expose this to monitoring tools. This will be a session that allows attendees to understand the power available to them in some of the overlooked core JVM features The session will use a combination of slides and examples that the attendees can code-along with on their own laptops, and will focus on what JMX is, how it works, and also how you can expose your own application MBeans and use these to monitor the application. In my work as a Java performance consultant, I have found that JMX and the basic JVM tooling that uses it, is not understood by developers, so this session is about raising awareness of these tools and allowing developers to get inside the JVM and their application to understand how it works (and write better code). In my experience, once developers understand the power of JMX and VisualVM, they find it very interesting, and often the best way to demonstrate it is by allowing people to work with it. The fact that the base JDK is all that is required to demonstrate this means that there are few pre-requisites for this session, and because it is based on a low level technology, it is of interest to people working on all aspects of Java. I think this could make popular talk which will help developers understand the magic and power behind the Java Virtual Machine.

Presentation by Matt Brasier, C2B2 Principal Consultant, delivered at DOAG German Oracle User Group Conference on the 20th of November 2014 in Nuremberg. One of the most often overlooked, and yet most powerful features of WebLogic is WLST, the WebLogic Scripting Toolkit. This jython based library allows you to connect to and interact with a weblogic domain; making configuration changes, deploying applications, creating new servers and doing anything else that you might do through the console. By scripting our domain builds and deployments, we can control our configuration and provide increased confidence in our ability to rebuild an environment in a DR scenario, and with automated deployment tools like puppet gaining traction in DevOps circles, the ability to completely script both the creation of the domain, and deployment of the application gives us great power. This presentation will look at how WLST can be used to build a domain, deploy an application, and then provide runtime monitoring.

Presented by Jaromir Hamala, C2B2 Senior Consultant, at JDays Conference on the 27th of November 2013. Cheap RAM means we can use more memory than an average disk size was not that long time ago. It's very tempting to increase size of our JVM heap and store more data in-memory. As always, there is a trade-off: Large heaps lead to higher latencies due to Garbage Collector overhead. This session will show different strategies for accessing off-heap memory and using the advantage of large RAM without paying the performance penalty.

Presentation delivered by Steve Millidge at DOAG German Oracle User Group Conference in Nuremberg, 19-21 November 2013. The real time web is coming with Websockets in HTML 5. The big question is how to deliver event driven architectures for websockets at scale. This session delivered by a member of the JSR 347 Data Grids expert group provides an insight on how combining Oracle Coherence with the new Websockets support in WebLogic 12c can deliver enterprise scale push to web devices. The session first provides an introduction to websockets and delves into typical Oracle Coherence architectures and how they deliver linear scalability and high availability. We then look at the event capabilities inherent in Oracle Coherence that when hooked up to the new WebLogic 12c Web Sockets server can deliver Coherence grid updates in real time to HTML 5 devices. The presentation will be a mixture of of animated graphical slides depicting how WebLogic Web Sockets and Oracle Coherence work, combined with code snippets. We will then provide a demo hosted on amazon EC2 of the described architecture for delegates to browse to and interact with to show the capabilities of websockets on their devices. Demos will again use Oracle Coherence and WebLogic 12c.

Fast Data: Parallel Processing on the Grid. You may think of in-memory datagrids as a big cache, a key value store accessed using put and get. However to really reap the power and scale of modern data grids you need to move beyond cache semantics and turn your architecture on its head. Moving the processing to the data rather than pulling the data across the grid massively increases parallelism and reduces network latency, leading to huge increases in throughput. In this session, we will explore why traditional cache semantics sometimes struggles to scale and how through using parallel processing and event processing on the grid we can rearchitect our systems for massive scalability and utilise all our grid cores for parallel processing.

Presentation by Nigel Deakin (Oracle) delivered at the first London GlassFish User Group (GUG) event on the 18th of September 2013. GlassFish 4.0 is the application server to support the new Java EE 7 standard. One of the most significant components of Java EE 7 is JMS 2.0, which is the first revision to the JMS (Java Message Service) API for over a decade and which introduces a new and much simpler API. This talk will review the new features of JMS 2.0 and other recent messaging-related changes in GlassFish 4.0.

'www.NoSQL.com' by Mark Addy The talk, split into two sections and drawing from a real implementation covers potential NoSQL architectures and the features they offer in the quest to reach the Holy Grail AKA linear scalability. First we examine an existing traditional replicated cache running at full capacity and how replacement with a distributed solution allowed the application to scale dramatically with a performance improvement to boot. Secondly we look at one of the pitfalls of distributed caching and how, using an essential tool from the Data Grid functionality armory, namely grid-execution we can provide massive scale out and low latencies. Both parts describe a real-world implementation delivered for a global on-line travel agency using Infinispan. Level: All levels, the talk is aimed at developers, architects and middleware specialists interested in caching solutions. Focus: Use-cases including technical detail.
