3.3.3.1 The Thread Analyzer Interface

The Thread Analyzer includes a menu bar, a tool bar, and a split pane that contains tabs for the various displays. The following three tabs are shown by default in the left-hand pane:

• The Deadlocks tab

  This tab shows a list of potential and actual deadlocks that the Thread Analyzer detected in the program. This tab is selected by default. The threads involved for each deadlock are shown. These threads form a circular chain where each thread holds a lock and requests another lock that the next thread in the chain holds.

• The Dual Source tab

  Select a thread in the circular chain and then click on the Dual Source tab. The Dual Source tab shows the source location where the thread held a lock, and the source location where the same thread requested a lock. The source lines where the thread held and requested locks are highlighted.

• The Experiments tab

  This tab shows the load objects in the experiment, and lists any error and warning messages. The following two tabs are shown on the right-hand pane of the Thread Analyzer display:

  • The Summary tab which shows summary information about a deadlock selected from the Deadlocks tab.

  • The Deadlock Details tab which shows detailed information about a thread context selected from the Deadlocks tab.
