The document discusses performance testing of an order management system. It includes an overview of the order lifecycle and system architecture. It describes the performance test strategy of conducting component and load tests. It details detecting performance bottlenecks through monitoring resources and analyzing logs and reports. It also discusses correcting bottlenecks, consolidating agent servers, and enabling on-demand provisioning.
While working with Java applications running on the Java HotSpot VM, we might sometimes encounter problems such as application hangs, memory leaks, unexpected application behavior, or crashes. Troubleshooting such problems can be very hard and tricky. But with knowledge of the right set of tools and utilities for nailing these problems down and how to approach them, troubleshooting can be made much easier and can help us develop stable, reliable, and efficient Java applications. This slides deck covers how we should approach these JVM issues and which tools and utilities are useful for diagnosing and troubleshooting them.
This is a copy of the NoSQL Day 2019 session presented in Washington D.C on May 2019. It covers a series of the most common HBase issues observed among Cloudera customer base, together with RCA and recipes for recovery.

Analyzing Billions of Data Rows with Alteryx, Amazon Redshift, and TableauDATAVERSITY
Got lots of data? So does Amaysim, a leading Australian telecom provider, with its billions of rows of data. The organization successfully empowers its small team of data analysts with self-service data analytics platforms so they can easily access the data they need, perform advanced analytics, and visualize findings for all stakeholders. Register for this session and learn how Amaysim uses the Alteryx-Redshift-Tableau BI stack to easily and quickly:
Extract data from their data warehouse and blend and enrich it with other sources
Give data analytical context by running statistical, predictive, and deep geo-spatial analytics
Create visualizations from analytics and then update Tableau Workbooks directly from Alteryx, or publish the results in Amazon Redshift, for easy direct access for their stakeholders from Tableau
Hear from Adrian Loong, Alteryx Analytics Certified Expert (ACE), and product marketers from AWS and Alteryx on how organizations can use Alteryx, Amazon Redshift and Tableau to enable data analysts to spin up new self-service analytics instances to enable fast investigation for critical business decisions.

UKOUG APPS 14: Optimizing Performance for Oracle EPM SystemsAlithya
Oracle's Enterprise Performance Management (EPM) is a cutting edge suite of tools engineered to deliver analytical insights to users at high speeds, but any competitive advantage is often blunted by sub-optimal infrastructure and easily remedied software configuration issues. The result is slow user response times, endless reboots, and lengthy calculation and consolidation times.
Edgewater Ranzal infrastructure consultant Paul Rix presents a compact guide on how to get the best performance from Oracle EPM investments as well as those planning for increased workload in the near future.
Mixing theory and real-world examples, we navigate the key elements of EPM performance tuning from the low hanging fruit of 10-minute fixes to the architectural and infrastructure blockages that commonly prevent EPM systems from reaching their true performance potential.

Best Practices for Becoming an Exceptional Postgres DBA EDB
Drawing from our teams who support hundreds of Postgres instances and production database systems for customers worldwide, this presentation provides real-real best practices from the nation's top DBAs. Learn top-notch monitoring and maintenance practices, get resource planning advice that can help prevent, resolve, or eliminate common issues, learning top database tuning tricks for increasing system performance and ultimately, gain greater insight into how to improve your effectiveness as a DBA.
More and more clients are looking to understand the capabilities of the OTM/G-Log architecture and configuration in order better tune OTM. Usually, this is required because of poor OTM performance or as preparation for significant changes to OTM configuration, volume, or platform. The client may be experience poor performance throughout the entire system or for a very specific use cases. The primary objective of a Performance Tuning Exercise is to understand how OTM is being utilized and to recommend solution to improve the performance of OTM.
We recommend and will take the audience through a “ground-up” performance tuning exercise, starting with hardware and infrastructure, moving to Java and App server tuning, then to OTM technical tuning and finally to the OTM functional tuning (data, agents, etc).
These audits may identify hardware constraints at each tier, networking, or other infrastructure constraints causing sub-optimal system performance. Simply stated, the performance audit will identify all bottlenecks in the system if they exist.
In many cases the largest performance is impacts are not hardware, but rather how the data is configured within the application. So as part of the exercise we will analyze database performance, individual SQL queries, OTM Queues, bulk planning parameters, agents, rates and the settlement process.
Understanding the methods which will best identify these bottlenecks will help you avoid performance issues early in your project and save considerable time and expense as you near go-live. This presentation will guide you through the steps necessary to better understand what is impacting performance and how to best handle it. It will provide lessons learned and tools that are available to you better manage and maintain a healthy OTM environment.

DrupalCamp LA 2014 - A Perfect Launch, Every TimeSuzanne Aldrich
Launches are tough on a new developer. Everyone remembers the lump in their throats around launch time; the rush to finish content, make final theme tweaks, adjust for sudden browser weirdness. As momentum picks up, the odd change request always appears, databases are slingshot hither and yon, while everyone scrambles to resolve merge conflicts like a Tokyo train at rush hour.
We emerge scarred but smarter, intent on making the next launch less painful. But with different teams launching different sites, it can be hard to establish an iterative process. Especially as new work accumulates in the backlog, we reap what we sow in technical debt from rushed launches, quick & dirty choices made under the gun, and unimplemented ideas from retrospectives.
Pantheon, however, has the same Customer Success team launching several enterprise sites per week, while assisting hundreds of self serve customers when they need a hand. Because we need to work effectively, we have developed the tools and process to ensure:
* Great Site Performance - On Day One
* Less problems over the long run
* Clear Expectations from Informed Stakeholders
The session will cover other key areas:
* Preparing For Launch for the PM, Stakeholder, Developer & Sys Admin
* Auditing the Site for landmines, carnivorous acid pool islands, and deadweight
* Load Testing to obliterate surprises with actionable results
This session is Platform Agnostic; whether you use PAAS, shared hosting, or wield your own hardware, PMs, developers, and clients will leave with new tools in their belt to launch with less agita. We will share some of our challenges and how we overcame them, and hopefully hear from you about how you overcame yours!
WebLogic Stability; Detect and Analyse Stuck ThreadsMaarten Smeets
Stuck threads are a major cause for stability issues of WebLogic Server environments. Often people in operations and development who are confronted with stuck threads, are at a loss what to do. In this presentation we will talk about what stuck threads actually are and how you can detect them. We will elaborate on how you can get to the root cause of a stuck thread and which tools can help you with that. In order to reduce the impact of having stuck threads in an application, we will talk about using workmanagers. In order to prevent stuck threads we will illustrate several patterns which can be implemented in infrastructure and applications. Next time you see a stuck thread, you will know what to do!
