Nuance Management Center Server Installation and Configuration Guide
Configuring your load balancer
If you have multiple NMC servers in your environment, you can use a load balancer to balance the incoming
client activity among your servers. You can configure the load balancer to make an API call periodically to
your servers to ensure they are operational.
Configure the load balancer to make the following API call:
https://<NMS-Server-Name>:443/Nuance.NMS.Services/
__NMSServiceStatus/Rest/Status
If operational, the NMC servers return the following XML response:
<ServiceStatusResponse xmlns=
"http://schemas.datacontract.org/2004/07/Nuance.NAS.Connector.
DictationTranscription" xmlns:i="http://www.w3.org/2001/
XMLSchema-instance">
__<Status>Running</Status>
__<ServerDateTimeUTC>2010-12-13T20:50:13.0969590Z
____</ServerDateTimeUTC>
__<InterfaceType>basicHttpTransport</InterfaceType>
</ServiceStatusResponse>
If the servers are down, the load balancer receives an error. If the load balancer receives anything other than
the expected response, it can tag a specific server as down and reroute network traffic.
