Parameter: HEARTBEAT_POLLING_PERIOD

Definition

The polling period in milliseconds of 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_POLLING_PERIOD parameter specifies the period in milliseconds between two pings. This mechanism detects down or newly restarted instances.

Notes:

• The smaller the value, the faster the detection of down or restarted instances is and the shorter the service interruption is. However more network resources are used. A high value makes the service interruption longer but the network resources usage is lower when all goes well.
• A similar parameter exists on client side through the com.highdeal.cnd.message.ServiceClientTuning class. Please consult this Java class documentation and the SAP CC Java API Reference (Javadoc) for more information.

Range: This parameter must be greater than 0.
