You can disable the load balancer to suspend the Oracle SOA Cloud Service instance temporarily, to block any new traffic from being delivered to the service instance. This is useful when you want to perform routine maintenance on an Oracle SOA Cloud Service instance, but do not want to stop the service instance. Once the maintenance activities have been completed, you can re-enable the load balancer to allow traffic to be delivered.
See Disabling or Enabling the Load Balancer for an Oracle Cloud Service Instance.
Note:
If a load balancer is not configured, you cannot suspend the Oracle SOA Cloud Service instance.
