    Expertise: Working on how to get the best out of the database, linux/solaris and systems


    Abstract 1: Setting up RAC to avoid application downtime

    Real Application Clusters are not just about avoiding unplanned downtime. They also help a lot with planned maintenance like hardware and operating updates and rolling patches. With the right setup, administrators do not need to get up for maintenance windows in the middle of the night to apply patch sets anymore. Using the right planning and strategy, routine tasks can be dealt with while the database is up and running. This presentation walks through the proper setup of applications, implementation of services and shows how perform maintenance in such a way that applications and end users do not even notice.

    We will also look at the new 12c feature Transaction Guard and Application Continuity and explain how they help to make client connections to RAC systems even more resilient.


    Abstract 2: Developing applications for RAC and Exadata - what you need to know

    It is often believed that applications will run fine without any changes on Cluster databases and engineered systems. But the reality for a lot of projects is that while things rarely break, the desired performance improvements from putting an app on a cluster database are rarely achieved and in addition a new class of problems pop up.

    This presentations aims to give the proper information to developers so they can identify and work around potential for contention and problems. Even though transparent to the application, we will cover the basics of cache fusion and implications on application performance and workload management. The session will also cover the tradeoffs developers have to make when dealing with singleton objects like sequences in a clustered environment and how to set up and test load-balancing and failover from an application perspective.

    Lastly, we will cover what can or needs to be done on the application side to make best use of features like Hybrid Columnar Compression and Smart Scans.


    Abstract 3: Implementing Hard Partitioning technologies to stop over-licensing

    Moore's law is giving us servers with ever-increasing throughput in terms of higher clock rates and cores per socket. If the database demands are not groing a lower rate, chances are that database servers (and as a result licensing costs) are becoming bigger than they need to be.

    Consolidation and sub-server licensing are ways to avoid licensing idle cpu capacity.

    This presentations introduces and explains the various ways that this can be achieved with Oracle VM, Solaris zones and LDOMs aswell as other technologies.

    Demonstrations showcase simple setup scenarios that attendees can easily replicate.

    Abstract 1 Getting Value from Big Data with Analytics

    The five top trends in technology right now are mobile, social, cloud, security, and big data and of all of those, the one that can add the most immediate business benefit is big data. Many discussions on big data center around "what does big data actually mean?" We will be talking about that (briefly) but we'll then get to a much more important question: how can I actually take big data and do something valuable with it? The secret is analytics: take big data and actually use it to drive business decisions. Using Oracle Business Analytics examples, we'll be showing that big data isn't all hype: there's value to your organization. Do you want to learn about big data and analytics? Then join us for this session.

    Expertise: performance, tuning, SQL, Enterprise Manager, data storage management


    Abstract 1: Database performance tuning

    DBA class
    45 minutes, 90 minutes or 3 hour workshop
    How does one know what the load is on an Oracle database? How does one identify whether database idle or if there is a bottleneck? Using a single metric of Average Active Sessions (AAS) and a simple list of rules one can easily answer these questions. Using AAS one can both quickly identify issues and then harness active session history (ASH) and ASH Analytics in EM to dive deep in to the details to resolve even the most challenging problems.

    Limits of AWR report for performance analysis
    Solution to performance analysis with sampling
    Sampling is used to build active session history (ASH)
    ASH is the basis for average active sessions (AAS)
    AAS visualized in EM and ASH analytics as well as with SQL queries
    Examples of solving problems with AAS in EM
    Examples of diving into ASH Analytics
    Examples of querying ASH directly


    Abstract 2: SQL performance tuning

    Developers & DBAs
    45 minutes, 90 minutes or 3 hour workshop
    As a developer how does one know the impact of their SQL code on the system? How can the SQL load be verified and most importantly if the load of the SQL is high and/or SQL performance is slow, how can one tune the SQL? This presentation will show to identify high load SQL and most importantly how to analyze a SQL statement to identify bottlenecks and tune the SQL.


    Analysis will go over :
    1. getting the correct execution plan along with extended execution statistics and how to analyze the statistics and predicate details in the execution plan.
    2. Cardinality : optimal execution plans are all about cardinality. We will go over how to get cardinality information in surprising, unique and powerful ways.
    3 Visual SQL Tuning (VST) : VST is a method of laying out the tables and joins of a query graphically indicating key features of the query in the graphics. With VST, you'll learn how to quickly visualize any coding errors in the query, discover flaws in the underlying database schema, and most importantly, find the best execution path through the query


    Abstract 3: Application Development performance tuning

    Managers, CIO, developers, DBAs
    45 minutes or 90 minutes
    Databases pose a unique hurdle in the world of application development, DevOps and Continuous Delivery. Most applications depend on databases and databases tend to be large, complex and difficult to copy. Development, QA and deployment testing all require environments and if when those environments include large databases then provisioning those databases becomes the biggest constraint in the flow of features. to setting up these environments. This presentation will go over the impact of managing databases in development flow and the strategies to alleviate the constraints imposed by databases. What strategies does one use in dealing with databases? Are rollback scripts feasible? Are subsets sufficient? Can synthetic data suffice?

    How long does it take a business analyst, developer or QA team to get a copy of production data ? What is the impact of the delays of getting data to the right place at the right time? How can we reduce this time and a reduce the resources required? We will explore what the impact the data constraint, find a solution to solve this constraint with and finally measure the improvements to the business by removing this data constraint.

    Expertise: Java and Cloud


    Abstract 1: Build and Monitor Cloud PaaS with JVM's Nashorn Javascripts

    Sure it is easy to use a web interface to build, manage, and monitor your Cloud PaaS instances. But it can be much easier to reuse several Java libraries, do REST calls, and leverage your PaaS SDKs with the Nashorn Javascript engine. In this session you will learn how to code useful Nashorn Javascripts to automate all the boring tasks you used to do in your browser. You will see examples for creating instances, diagnosting their health, scaling up and down your infrastructure, and a bonus for building a JavaFX interface without compiling a single line of code, just using Nashorn. Say no more to bash scripts. It's time to code Javascript in your Unix box!


    Abstract 2: Cloud Services for Developers: What's inside Oracle Cloud for you?

    Developers want to build cool stuff with cool stuff. What's cool about Oracle Cloud is that it brings great technologies, enterprise-ready, long-time proven, and ready for consumption, all combined together as a Platform as a Service. Learn what kind of data management technologies it offers, and how to access them from a wide range of Middleware and Java-based Cloud services. Learn how to manage your source codes and Git repositories in the Cloud with Continuous Integration and Delivery approaches, and how to plug all that from your preferred IDEs.


    Abstract 3: Lambdas and Streams, Functional Programming in JDK 8

    The significant new language feature in Java SE 8 is the introduction of Lambda expressions, a way of defining and using anonymous functions. On its own this provides a great way to simplify situations where we would typically use an inner class today. However, Java SE 8 also introduces a range of new classes in the standard libraries that are designed specifically to take advantage of Lambdas. These are primarily included in two new packages: and java.util.function. After a brief discussion of the syntax and use of Lambda expressions this session will focus on how to use Streams to greatly simplify the way bulk and aggregate operations are handled in Java. We will look at examples of how a more functional approach can be taken in Java using sources, intermediate operations and terminators. We will also discuss how this can lead to improvements in performance for many operations through the lazy evaluation of Streams and how code can easily be made parallel by changing the way the Stream is created.

    Abstract 1: Disaster Recovery as a Service (DRaaS) is at your doorstep – will you let it in?

    Natural disasters are not something that should be taken lightly when talking about Disaster Recovery (DR), the impact on the business can be catastrophic. But there are many research studies showing that one of the reasons many companies experience interruptions or even data loss are caused by human error. The combination of hardware, software, and people operation is prone to failures and require contingencies in order to maintain the continuity of businesses.
    There are options to protect your business against disaster, whether it is human, hardware or a natural disaster. Your company can invest in all of the components to establish a protected environment in-house – most of the time at a high level of customization and engineering requirements not to even mention the cost. Why not adopt a solution of DRaaS (Disaster Recovery as a Service) where all of the components of the solution have been already engineered together?
    In this session we will review DRaaS; what is it? Things that should be considered as well as highlighting areas such as lower total cost of ownership, higher level of customer satisfaction and faster go to market - you can literally start protecting your business tomorrow.

    Abstract 2: Can DRaaS help you protect your data?

    Mention natural disasters and many might get a cold shiver going down their spine with just the thought of it – no need to even mention Storm Sandy and the Japan Tsunami. Guaranteeing the continuity of your business during a major natural disaster in itself is challenging, but even an operating system or database corruption may be a challenging proposition to take on. Establishing multiple datacenters - from installation, operation to interconnecting them, ensuring that your data is protected - can be challenging. Do you have individual Service Level Agreements (SLA)? Maybe you have 99.99% of availability for you servers, 99.83% for the datacenter, but 99.6% for your network? Why not review Disaster Recovery as a Service (DRaaS)? A DRaaS provider can give you a single SLA for everything from the network, datacenter, servers, operating system, DBA services, all the way through to the business continuity applications. While the DRaaS provider guarantees your peace of mind, you work with your business counterparts to develop sustainable competitive business advantages.

    Abstract 3: Why Oracle Standard Edition Should Still Be on the Menu

    Stop… and consider Standard Edition (SE). SE is sometimes the neglected smaller brother of Enterprise Edition (EE). Most focus on the new features available in the EE stack, but what about SE?
    Some forget it is still the same core database. It can provide highly available solutions as well as help establish a robust DR environment. It is even possible to use Oracle RAC with SE, and combined with a standby database, you can implement a powerful solution. To top this all off, you gain the added advantage of lower licensing cost. Whether you are a small business or enterprise, SE may well suit your needs and as the cost saving can be substantial it is worth consideration.
    Let’s go on a journey to look at why SE should still be on the menu looking at areas such as Migrating between editions as well as new Oracle 12c Features available in Oracle Standard Edition.

    Abstract 1: Hangover - What happened yesterday ?

    Would like to show the power and useful benefits for Troubleshooting with ASH Views (Active Session History), which are key for troubleshooting for an event in the past, mentioning key things as the fact that when using ASH is very important to count the results of queries for the events we are looking for, cause those views are based on snapshots, so to really figure out when some event was happening during certain period of time, the count for the range of time is the right way to see which event was really happening most.

    Also, because this beautiful feature is only available for those with Enterprise Edition and Diagnostics Tuning Pack, Would like to show another option for the ones without EE..... there is out there an open source solution that's try to emulate the same functionality, for those without the luck of enough licenses and or running Standard Edition (Perhaps also an old Oracle version), would like to show about S-ASH Views to do same or pretty close same things as with ASH views.
