Plugin installation

To enable integration, you should install the profiler plugin.

To install the plugin, run the profiler.

Use Profile from within IDE... action on Welcome screen or in "Tools" menu, select "JDeveloper" and follow the instructions.

Profiling from JDeveloper

After the plugin is installed, Profile actions are added to the main menu ...

... and to context menus:

...and in the main toolbar:

You can configure profiling parameters in the Project Properties dialog's node YourKit Java Profiler.

The Profile action starts the profiled application, and connects to it in profiler UI (unless opposite behavior is configured). The output of the profiled application appears in console, same as for Run action.

JVM architecture selection

This topic is not applicable to macOS where the profiler agent a universal binary.

On a 64-bit machine, the Profile action must know whether the JVM for launching the profiled application is 32-bit or 64-bit, in order to supply appropriate profiler agent version.

By default, the plugin attempts to automatically detect the JVM kind by obtaining available information from JDeveloper.

For particular run configurations this may happen that the automatic detection is not possible. In this case Profile will fail with an error like Error occurred during initialization of VM. Could not find agent library printed in the JDeveloper console. In this case use the "JVM architecture selection" section to specify the architecture explicitly.

Navigation action

While profiling, you usually need to browse the related source code to understand the performance problems at hands. After the problem is located, you edit the source code to fix it.

Use Tools | Open in IDE (F7) to open the underlying source code in the editor of your IDE - the best place to browse and edit code.

The navigation action works on the current selection and is available in both CPU and memory views.

Note: navigation to inner classes is not possible because JDeveloper does not provide appropriate API.
