Overview of Failover Support
Failover support allows you to recover from system failures that occur during processing, making your applications more robust. For example, by having more than one Integration Server, you protect your application from failure in case one of the servers becomes unavailable. If the webMethods Integration Server to which the client is connected fails, the client automatically reconnects to another webMethods Integration Server in the cluster.
Note: webMethods Integration Server clustering provides failover capabilities to clients that implement the webMethods Context and TContext classes. Integration Server does not provide failover capabilities when a generic HTTP client, such as a web browser, is used.
You can achieve failover support a number of ways:
webMethods Integration Server clustering. With multiple
webMethods Integration Servers, if one
Integration Server fails, requests can be automatically redirected to another server, thereby avoiding a single point of failure.
Redundant hardware configurations. By specifying hardware configurations that are redundant, for example multiple machines, multiple file servers, and so on, you further reduce the chance of a single point of failure.
