writing BPF/BCC scripts are a mixture of coding in Python and C, which feels to me both familiar and at the same Time strangely low-level compared to the more mature environments for example of DTrace and SystemTap.The example scripts that I had written using BPF/BCC is on Github(link is external). Here's a list with comments:

If you see the Webcenter Space app (Webcenter.ear) from the WebLogic console, the session timeout (3,600 seconds) session timout is misleading and is not applicable in the case of webcenter space applications. If you update the value from the console, it does not affect the session time-out of the Webcenter space application. Then, the question is how can I change the Webcenter space app session timeout? The default session timeout in Web. XML is set to 45 minutes. There are two ways to change t

encapsulates a method so that the method can be called anonymously. An event is a method that a class allows a client to provide a delegate for which the methods should be invoked when the event occurs. When an event occurs, the delegate that its customer provides to it is invoked.
In addition to declaring events, invoking events, and hooking up with events, the following topics are covered in this tutorial:
