• StuckThreadDetectionValve

  public StuckThreadDetectionValve()

  Required to enable async support.

Method Detail

• setThreshold

  public void setThreshold(int threshold)

  Specifies the threshold (in seconds) used when checking for stuck threads. If <=0, the detection is disabled. The default is 600 seconds.

  Parameters:

  threshold - The new threshold in seconds

• getThreshold

  public int getThreshold()

  Returns:

  The current threshold in seconds

  See Also:

  setThreshold(int)

• getInterruptThreadThreshold

  public int getInterruptThreadThreshold()

• setInterruptThreadThreshold

  public void setInterruptThreadThreshold(int interruptThreadThreshold)

  Specifies the threshold (in seconds) before stuck threads are interrupted. If <=0, the interruption is disabled. The default is -1. If >=0, the value must actually be >= threshold.

  Parameters:

  interruptThreadThreshold - The new thread interruption threshold in seconds

• initInternal

  protected void initInternal()
                       throws LifecycleException

  Description copied from class: LifecycleMBeanBase

  Overrides:

  initInternal in class ValveBase

  Throws:

  LifecycleException

• getInfo

  public java.lang.String getInfo()

  Return descriptive information about this Valve implementation.
