Parameter: HEARTBEAT_DEAD_CONNECTION_PERIOD_COUNT

Definition

The number of polling periods after which an instance is considered as down with the heartbeat mechanism

Description

The heartbeat mechanism is in charge of checking whether the instances are still alive by pinging them at regular intervals. The HEARTBEAT_DEAD_CONNECTION_PERIOD_COUNT parameter specifies the number of periods without response from an instance before considering the instance as down.

Notes:

  • The dead connection timeout equals (number of periods * HEART_BEAT_POLLING_PERIOD).
  • A value too small can make the heartbeat mechanism detect down connections even with a running instance because the remote instance may not have enough time to reply. A value too high makes service interruption very long when an instance is down.
  • A similar parameter exists on client side through the com.highdeal.cnd.message.ServiceClientTuning class. Consult this class documentation and the SAP CC Java API Reference (Javadoc) for more information.
