This was promising, so I give it a short try for Oracle ADF applications. For this blog I use the Summit ADF application, delivered by Oracle, but I have tried with our own application too. Test is done in JDeveloper 12.1.2.
After the download there are some easy steps of setup to do:
Then edit this configuration
and add XRebel path as described in the documentation:
Save the configuration by pressing OK two times.
Then open your Page and run it via the run configuration:
As First you see one time a dialog to request and enter the trial license.
Then you see the XRebel widget on the left side and after waiting some little time the first issues are shown.
From the default configuration (which can be changed with the gear in the widget) there seems a problem with the size of the session and with SQL Queries. If you drill down to the queries tab on the SQL page you see the execute queries, sorted by execution time, maybe the app should execute some of the queries at least not before changed to the tab, where it is used?
If you look at the session size, then interesting is, that most of the session size is hold on the ODL log manager. Maybe oracle should think about this result, maybe there is a better way to hold this data.
So download XRebel and give it chance on your ADF application.
