WildFly 33 Model Reference

A messaging resource that allows you to configure High Availability for the ActiveMQ server (the value of ha-policy can be live-only, replication-master, replication-slave, replication-colocated, shared-store-master, shared-store-slave, or shared-store-colocated).

Attributes (8)

  • allow-failback Whether a server will automatically stop when a another places a request to take over its place. The use case is when a regular server stops and its backup takes over its duties, later the main server restarts and requests the server (the former backup) to stop operating.
