If you want to specify a backup server in case the remote server is not available, specify that backup server as the retry server on the remote server's alias definition.
In a stateful cluster, use the
$clusterRetry parameter that is passed to the
pub.remote:invoke service to control what happens when an
Integration Server tries to connect to the remote server in a stateful cluster. If you want the
Integration Server to first try other servers in the cluster when the remote server is not available, and then go to the retry server if no cluster servers are available, set
$clusterRetry to true. If you do not want the
Integration Server to first try other servers in the cluster but rather to go directly to the retry server, set the parameter to false. For more information about remote servers, see
Setting Up Aliases for Remote
Integration Servers. For more information about the
pub.remote:invoke service, see the
pub.remote:invoke.
