Tuning stuck thread detection behavior

WebLogic Server diagnoses a thread as stuck if it is continually working (not idle) for a set period of time. You can tune a server’s thread detection behavior by changing the length of time before a thread is diagnosed as stuck, and by changing the frequency with which the server checks for stuck threads.

To configure stuck thread detection behavior:

  1. If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
  2. In the left pane of the console, expand Environment > Servers.
  3. On the Summary of Servers page, select the server instance for which you will configure thread detection behavior.
  4. On the Configuration > Tuning tab, update as necessary:
    1. Stuck Thread Max Time -- Amount of time, in seconds, that a thread must be continually working before a server instance diagnoses a thread as being stuck.
    2. Stuck Thread Timer Interval -- Amount of time, in seconds, after which a server instance periodically scans threads to see if they have been continually working for the configured Stuck Thread Max Time.

    For more information about low memory detection properties, see Configuration Options.

  5. Click Save.
  6. To activate these changes, in the Change Center of the Administration Console, click Activate Changes.
    Not all changes take effect immediately—some require a restart (see Use the Change Center).

After you finish

You must reboot the server to use the new stuck thread detection behavior values.
