Processing large XML files in the SOA Suite

Emiel Paasschens 13

Read large XML files in chunks . Introduction At my current project, XML files are uploaded by the end-user in order to be processed in the Oracle SOA Suite. The XML files contain information about employers and their employees. Because an employer can have hundreds and even thousands of employees, […]

Instrumenting, Analysing, & Tuning the Performance of Oracle ADF Applications

Frank Houweling

Last week I presented at the  UKOUG’14 conference on instrumenting, analyzing, & tuning the performance of Oracle ADF applications. Instrumentation refers to an ability to monitor or measure the level of a product’s performance, to diagnose errors and to write trace information. Instrumenting gives visibility and insight of what is happening inside the […]

ADF Performance Monitor: Measuring Slow Network Time

Recently I was implementing the ADF Performance Monitor at a customer site and doing a detailed performance analysis. This customer had severe (and less severe) performance problems but was unable to pinpoint the exact pain points. Frequently, end-users were complaining because they were experiencing first a very good performance (response times […]

ADF Runtime Diagnostics: Instrumenting your ADF Application – Part 2

Frank Houweling

In a series of blog articles I show how you can instrument your ADF Application key actions. Instrumenting gives visibility and insight of what is happening inside the ADF application and in the ADF framework (what methods and queries are executed, when and how often). These runtime diagnostics can be very effective in […]

ADF Performance Monitor: Customer Case Video

Frank Houweling

The ADF Performance Monitor is designed for measuring, analyzing, tuning, and checking the performance of Oracle ADF applications. The monitor can track and collect crucial (production) performance information of the application’s runtime ADF components that are not standard provided by Oracle. It helps development, QA, and operation teams to detect, […]

ADF Performance Monitor: Detecting and Analyzing a High ADF BC Memory Consumption

Frank Houweling 2

Like other web applications, Oracle ADF applications potentially use a lot of JVM memory. Many times, the root cause of a high memory usage is that application data retrieved from the database into memory is not properly limited; hundreds or thousands of rows (with too many attributes) are fetched and […]

ADF performance tuning: Whitepaper published on the ADF Performance Monitor

Frank Houweling

The AMIS ADF Performance Monitor is an advanced tool designed for measuring, analyzing, improving, and checking the performance of Oracle ADF applications. The monitor can track and collect crucial (production) performance information of the application’s runtime ADF components that are not standard provided by Oracle. It helps development, QA, and […]

ADF Performance Tuning: Improve Your Oracle ADF App Response Time by as Much as 70 Percent

Frank Houweling

Performance needs to be ingrained in your application – it cannot be added in during the last stages of development. In this video I discuss how you can optimize the performance of your Oracle ADF Fusion application, diagnose and solve typical performance problems, and build an efficient, responsive, scalable ADF […]

JavaOne 2013: Java Mission Control

Frank Houweling 1

The convergence project between Oracle’s JVMs JRockit and Hotspot is making significant progress. Included in the latest Java 7 JDK update (‘7u40’) is a new powerful monitor tool: Java Mission Control (JMC). JMC is a production time tool that has its roots in the JRockit JVM tooling. It is located in the […]

JavaOne 2012: Thinking Through Java Enterprise Performance (BOF 4712)

Lucas Jellema

Performance of Enterprise Java Applications is a requirement and usually a challenge. Business requirements on systems can be stiff, successful systems can easily be overloaded and complex application architectures can add a burden too. Improving performance by tuning the application after it has been built seldomly renders huge improvements. By […]

Bloom Filters, Hierarchical Profiling, Synopses & One pass distinct sampling, jumping the GAPP … – feast for DBAs (considered harmful..)

Lucas Jellema

  It’s Monday night and a select company of DBAs and Database developers have gathered at AMIS HQ in Nieuwegein for the ‘Looking Back at Hotsos 2009’ session. It is one of those sessions that has a lot of energy, laughter and a wealth of serious content. Four very experienced […]
