Thread Contention (THRDCON)
Use the Thread Contention hyperlink to access the THRDCON view to see threads that are in blocked state. A blocked state exists when one method is waiting for a Java resource held by another thread in the same JVM.
The following figure shows a sample of the THRDCON view with contentions (BLOCKED thread state) in Thread-10, Thread-11, Thread-13, Thread-14, Thread-17:
In this sample, you can hyperlink from Thread-10 to access the following Thread Detail view (THRDDTLD):
In the detail view, Lock Owner Name shows the line number of the Java class in another thread (Thread-11) where the lock occurred. Blocked Object identifies the object for which the blocked thread (Thread-10) is waiting (java.lang.String@d388acf1).
The view provides the following hyperlinks:
Hyperlink from | To access |
|---|---|
Thread Name | Thread Detail Summary view (THRDDTLZ), showing details for the thread |
Lock Owner Name | Thread Detail Summary view (THRDDTLZ), showing details for the thread lock owner |
