Viewing all connected threads
You can display all active threads connected to a DB2® subsystem or a member of a data sharing group.
To do this, you can choose one of the following ways:
- In the System Overview window, select the DB2 subsystem or member of the data sharing group
in the folders pane and then click the Thread Summary toolbar
button (
). - You can also use the menu bar or pop-up menu: click the DB2 subsystem or member of the data sharing group in the folders pane, then click on the menu bar or on the pop-up menu.
If you are not connected to the selected DB2 subsystem, you are prompted to log on.
The Thread Summary window is displayed. It contains the key performance counters for all connected threads. If a thread has children, the number shown in the Parallel Threads column includes the parent thread.
To refresh the thread activity data, in the toolbar, select Automatic in the Refresh field. By default, values are updated every six seconds. To change the interval, click in the time field next to the Refresh field and overtype the value according to your requirements.
