The following tables list the valid ha-policy configuration elements when using a replication HA policy.

Table F.1. Configuration Elements Available when Using Replication High Availability



Applies to master brokers only. Determines whether the master checks the cluster for another master server using its own server ID when starting up. Set to true if you want to fail back to the original master broker. The default is false.


Name of the cluster configuration to use for replication. This setting is only necessary if you configure multiple cluster connections. If configured, the the cluster configuration with this name will be used when connecting to the cluster. If unset, the first cluster connection defined in the configuration is used.


If set, slave brokers will only pair with master brokers with the matching group-name.


The amount of time the replicating broker will wait at the completion of the initial replication process for the replica to acknowledge it has received all the necessary data. The default is 30,000 milliseconds, or 30 seconds.


During this interval any journal related operations will be blocked.


Applies to slave brokers only. Specifies how many times a slave broker can restart after moving its files on start. Once there are this number of slave journal files the broker will stop permanently after if fails back. The default is 2.


Applies to slave brokers only. Determines whether the slave broker will automatically restart and resume its original role when another broker places a request to take over its place. The default is true.
