From USENIX LISA 2010, San Jose. Visualizations that include heat maps can be an effective way to present performance data: I/O latency, resource utilization, and more. Patterns can emerge that would be difficult to notice from columns of numbers or line graphs, which are revealing previously unknown behavior. These visualizations are used in a product as a replacement for traditional metrics such as %CPU and are allowing end users to identify more issues much more easily (and some issues are becoming nearly impossible to identify with tools such as vmstat(1)). This talk covers what has been learned, crazy heat map discoveries, and thoughts for future applications beyond performance analysis.

Senior Architect David Reines will present the simple yet powerful clustering capabilities of Terracotta. David will include a brief overview of the product, an in-depth discussion of Terracotta Distributed Shared Objects, and a live load test demonstrating the importance of a well designed clustered application. David Reines is a Senior Consultant at Object Partners Inc. He has lead the development efforts of several mission-critical enterprise applications in the Twin Cities area. During this time, he has worked very closely with numerous commercial and open source JEE technologies. David has always favored a pragmatic approach to selecting enterprise application technologies and is currently focusing on building highly-concurrent distributed applications using Terracotta.

Hadoop is sparking a Big Data analytics revolution. But all the Hadoop insights in the world are worth nothing unless they lead to new, profitable action. To translate Hadoop insights into action in real time, more and more enterprises are combining Hadoop with the power of in-memory computing. Join us as we outline the tremendous benefits of merging Hadoop with in-memory data management, the challenges of doing so, and tips for getting started.

Clustering Java applications with Terracotta and Hazelcast

Terracotta (an open source technology) provides a clustered, durable virtual heap. Terracotta's goal is to make Java apps scale with as little effort as possible. If you are using Hibernate, there are several patterns that can be used to leverage Terracotta and reduce the load on your database so your app can scale. First, you can use the Terracotta clustered Hibernate cache. This is a high-performance clustered cache and allows you to avoid hitting the database on all nodes in your cluster. It's suitable, not just for read-only, but also for read-mostly and read-write use cases, which traditionally have not been viewed as good use cases for Hibernate second level cache. Another high performance option is to disconnect your POJOs from their Hibernate session and manage them entirely in Terracotta shared heap instead. This is a great option for conversational data where the conversational data is not of long-term interest but must be persistent and highly-available. This pattern can significantly reduce your database load but does require more changes to your application than using second-level cache. This talk will examine the basics of what Terracotta provides and examples of how you can scale your Hibernate application with both clustered second level cache and detached clustered state. Also, we'll take a look at Terracotta's Hibernate-specific monitoring tools.

Oracle exalytics deployment for high availability

The need for gleaning answers from data in real-time is moving from nicety to a necessity. There are few options to analyze the never-ending stream of unbounded data at scale. Let’s compare and contrast the core principles and technologies the different open source solutions available to help with this endeavor, and where in the future processing engines need to evolve to solve processing needs at scale. These findings are based on the experience of continuing to build a scalable solution in the cloud to process over 700 billion events at Netflix, and how we are embarking on the next journey to evolve unbounded data processing engines.

The venerable Servlet Container still has some performance tricks up its sleeve - this talk will demonstrate Apache Tomcat's stability under high load, describe some do's (and some don'ts!), explain how to performance test a Servlet-based application, troubleshoot and tune the container and your application and compare the performance characteristics of the different Tomcat connectors. The presenters will share their combined experience supporting real Tomcat applications for over 20 years and show how a few small changes can make a big, big difference.

Through a combination of Amazon ECS and open source technologies, customers are able to build portable CI/CD pipelines on AWS. As container based deployments become more complex, they require additional rigging for integration. In this session, we show how popular Apache products like Kakfa, Storm, and Zookeeper are being deployed on top of Amazon ECS. We hear from HERE, a provider of mapping data, technologies, and services to the automotive, consumer, and enterprise sectors about an approach that leverages Consul from Hashicorp and Amazon ECS clusters for short-cycle deployments and tag-based environment promotion.

In the enterprise there are rarely simple solutions to highly nuanced problems that satisfy all needs. Several customers might each ask "How do I make Jira/Confluence faster?" and each require a different answer. Using this example, this talk will pick apart the inputs, outputs, concerns, and realities of answering a short question with a long answer. We'll then discuss real-world examples from our own internal instances, to give you a taste of the process we've gone through to solve our own performance problems, and to show why there is no simple playbook; "it depends" on a lot! The key takeaways are: * The importance of having a shared definition of performance * The importance of having agreed-upon priorities, including what isn't important * The importance of measuring (allthethings) and understanding them * The thing you think is the problem might not be the problem, and vice versa. * The real world and the ideal world tend to look nothing alike!

Presentation given to the Kingdom of Saudi Arabia Oracle User Group August 13 2022, "Terraform on Oracle Cloud Infrastructure: A Primer for Database Administrators" Cloud services offer inexpensive, limitless resources where database teams can practice and validate performance tuning, high availability, and patching. The catch? Who sets it up? Navigating a cloud interface to create hosts, assign disks, and configure networking is tedious and time consuming. And you still have to install software and prepare the environment! Enter Terraform, an automation tool that streamlines and simplifies infrastructure builds. In this session, database administrators learn the basics to provision a database and supporting infrastructure on Oracle Cloud with Terraform. No prior experience with Terraform or Oracle Cloud is required!

In this session, Netflix provides an overview of Keystone, their new data pipeline. The session covers how Netflix migrated from Suro to Keystone, including the reasons behind the transition and the challenges of zero loss while processing over 400 billion events daily. The session covers in detail how they deploy, operate, and scale Kafka, Samza, Docker, and Apache Mesos in AWS to manage 8 million events & 17 GB per second during peak.

Organisational success today depends on effective communication and collaboration with individuals from cultures with varying beliefs and practices. Indeed, with the workforce increasingly comprised of people of varying cultural backgrounds, leaders must now prioritise the significance of cultural competence in the workplace. Ensuring cultural competence at every level of your organisation cannot be understated. While cultural disparities can manifest in different ways, as a leader, you must build deep and nuanced cultural competence skills and education to accurately spot, address and alleviate the various scenarios that can arise. Failing to recognise the importance of cultural competence or not acting to improve it can lead to cultural negligence. There are a few things to consider to ensure your organisation is on the right track. In this deck, you'll understand the importance of building cultural competence in the workplace. You'll also learn • The three (3) dimensions of Cultural Competence in the workplace • Key strategies to build a culturally competent workforce • Major benefits you stand to gain by having a culturally competent team.
