Monitoring ADF Pages Round-Trips with the HTTP Analyzer

Here is a short demo that shows how to use the HTTP Analyzer in JDeveloper to monitor and sniff the network traffic between an ADF Faces page (or any other web page) and the middleware. This can be a handy thing to use when you want to tune the performance of your ADF pages.

In the demo I show:

  • How to setup the HTTP Analyzer - using it as a replacement proxy
  • Monitor the HTTP traffic for your ADF page
  • The influence of the RangeSize parameter in the binding layer
  • The way an ADF table behaves and how it does pagination for you

Remember that this is only one of the things you can do to improve the performance of your ADF applications - there are many other things that can probably influence the performance in bigger ways. See for example this list from the Fusion Middleware Performance and Tuning Guide.

P.S.

In the demo you'll see that I'm starting Firefox with the following command line: "firefox -no-remote -P Debugging", this allows me to have a separate profile defined where I can set the proxy settings without messing up my regular firefox instance.

Note that you can then switch the command line that start the browser from inside JDeveloper in tools->preferences->web browser and proxy - to automatically start the browser with these options.

Don't miss Virtual Developer Day - All about ADF next week

In case you haven't heard we are holding a free online virtual developer day next week - July 10th that you should attend - even if you think you already know ADF.

First the registration link - http://bit.ly/fusiondev.

While one of the tracks is aimed at developer who are relatively new to ADF - and cover ADF Faces, ADF Controller and a comparison of productivity with Forms and other tools - the two other tracks have great content on some topics that you might not be familiar with even if you already work with ADF.

This include sessions about the upcoming ADF Mobile, The new ADF support in Eclipse and information about Application Life Cycle Management with ADF and JDeveloper. As well as sessions that will open your mind to the areas where ADF integrates with other Fusion Middleware Solutions such as ADF integration with BI, WebCenter and SOA.

Most of the sessions are quite heavy on demos and you'll get a chance to interact with the presenters and ask questions during the live event.

You should register even if you can't attend the live event - this way you'll get an email pointing you to the recorded sessions for on demand viewing.

See you next week.
