High Availability for Client-Server Communication
The client provides reliable event messaging from cache server to client to prevent data loss during server failover operations. High availability is implemented in the cache server and is configured in the client.
See server documentation at Configuring Highly Available Servers for details about configuring a server for high availability.
Configuring Clients for High Availability
Configure high availability by setting the pool attribute
subscription-redundancyto the number of copies maintained.
Sending Periodic Acknowledgment
Servers use periodic acknowledgment to reduce the likelihood of duplicate notifications, and to reduce resource usage.
