ADF Debugging Aid: The ADF Request Analyzer

Seasoned Oracle ADF developers will be familiar with the ADF Logging framework, an instrumentation API that you can use to surface what your application is doing behind the scenes, mainly as a debugging aid.  The ADF framework itself uses the ADF Logging framework to produce copious logs showing what the framework actually does for you.

Admittedly reading the logs, either your's or Oracle's can be a rather tedious process.  Let's admit it, reading text files with 1000 of lines of output isn't what we signed up for when we joined the exciting world of the IT industry.  Arguably reading the logs can also be like drinking from a fire hose too, there's just too much information to digest.

To make your life a little easier as a developer, Oracle's JDeveloper includes the Oracle Diagnostic Log Analyzer which is a visual tool included in the IDE designed to allow you to search, filter and read the logs in a structured fashion.

A superb addition to the Oracle Diagnostic Log Analyzer is the ADF Request Analyzer.  The ADF Request Analyzer is not just designed to assist you read the logs, but restructures the logs to represent the JSF & ADF lifecycle on each request.  In other words it moves from a flat line by line log structure which doesn't really represent the flow or logic of how each request is processed, to showing you visually in a tree structure the different phases of the lifecycle processing the request.

Interjecting with one of the main benefits I see from a personal perspective, the ADF Request Analyzer takes that dry JSF lifecycle you read about in books but never really understood as it was all theoretical, and now shows you the runtime representation of the lifecycle so you really get to see what gets processed when.

For customers who don't know about this tool, the ADF product management team has released a new ADF Insider video on the ADF Insider Essentials YouTube channel entitled the Oracle Diagnostic Log Analyzer - ADF Requests and the JSF Lifecycle.  To make it a little more realistic than "here's the tool and you should use it", the video attempts to show you some real running scenarios, as well as how you would use it in a production environment.

We hope you find this useful.  As can be seen Oracle's ADF Product Management team continue to commit to providing customers comprehensive learning collateral on your ADF endeavours, with the ADF Insider Essentials channel, ADF Architecture TV, ADF Mobile Academy and much more.
