If one server address does not result in a successful session, the failover function allows the Jolt Client API to connect to the next free (unconnected) JRLY specified in the argument list of the API. To enable this failover in a Windows environment, multiple Windows JRLY services can be executed. In a non-Windows environment, multiple JRLY processes are executed. Each JRLY (service or process) has its own configuration file. This type of failover is handled by the client API features in Oracle Jolt, which allow you to specify a list of Jolt server addresses (JSL or JRLY).
