EFT Best Practices

Use Unicast Instead of Multicast HA Configuration

EFT High Availability (HA) users can increase system stability and throughput by using unicast network configuration instead of multicast. TCP-based unicast communication is widely supported by all networks. It enables high availability support for environments that do not support multicast broadcasting. It also improves node-out-of-sync detection and availability. 

Best Practice

Apply unicast to boost the reliability and flexibility of your EFT deployment, further ensuring safe delivery of your critical file exchanges. 

To use unicast, a registry setting must be enabled:


  • Multicast broadcasting is the system default. TCP (unicast) method of broadcasting ftp.cfg was developed for environments that do not support multicast (e.g., Azure and vMotion).  
  • To use the TCP instead of multicast broadcasting, set the Advanced Registry key ClusterCoherenceQueueMsmqType to msmq-iterative     

Example: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\GlobalSCAPE Inc.\EFT Server                       7.4\ClusterCoherenceQueueMsmqType=msmq-iterative

HA Unicast Configuration

  • To use multicast broadcasting, either delete the key or set the ClusterCoherenceQueueMsmqType = msmq-multicast

Example: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\GlobalSCAPE Inc.\EFT Server 7.4\ClusterCoherenceQueueMsmqType=msmq-multicast
