ADF Performance Monitor: Support for EJB/JPA (EclipseLink)

Frank Houweling

Not all Oracle ADF projects are built with ADF Business Components (ADF BC). Some organizations prefer to use EJB/JPA (EclipseLink) instead of ADF BC. The EclipseLink JPA provides developers with a standards based Object-Relational persistence solution. The application still reflects the Model-View-Controller architecture. In this case the model is provided by […]

ADF Performance Monitor: Measuring Network Time to Browser and Browser Load Time

Frank Houweling

Recently we added a great new feature to the ADF Performance Monitor: network and browser load time information. Now you know exactly every end-user experience of your ADF application, in real-time. You can quickly resolve any performance bottlenecks with this end-to-end visibility. You can even drill down into an individual user to […]

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 […]

Do it yourself Transaction Recorder – when standard auditing is not available

Lucas Jellema

In the recently published blog article Database Transaction Recorder – Adding Who to When and What to make Flashback take over from Journalling tables (https://technology.amis.nl/blog/10911/database-transaction-recorder-adding-who-to-when-and-what-to-make-flashback-take-over-from-journalling-tables) I have discussed how the replacement in database oriented applications of journaling tables by flashback data archives can be completed by recording the transaction history […]
