The <MB_HOME>/repository/conf/hazelcast.properties file is used to configure Hazelcast parameters that affect the performance of your MB cluster. The configurable parameters are as follows.

Element NameDescriptionTypeDefault ValueNotes
hazelcast.max.no.heartbeat.secondsThe maximum time period that should elapse between pings received from a worker node in an MB cluster before acknowledging that worker node to be dead. This parameter prevents the allocation of resources to inactive worker nodes, thereby avoiding unnecessary system overheads.Integer600This value is specified in seconds.
hazelcast.shutdownhook.enabled

This parameter specifies whether the Hazelcast shutdown hook is enabled or not.

When this parameter is set to false, the inbuilt shutdown hook thread of Hazelcast is disabled. This is because the WSO2 message broker is manually shutting down the hazelcast service.

BooleanfalseThis parameter is not configurable.
