Because Symfoware Server realizes failover, you can build a high-availability system. The operation involved in performing failover is referred to as the failover operation.
Failover refers to the facility that enables the taking over of a job that is being operated on the relevant node to another node (standby system) if an error occurs on one of the nodes in the cluster system. The following two functions of Symfoware Server are used to realize failover:
The standby function is such that, if an error occurs in a node, the standby RDB system to which the operation is to be switched is started up to take over the job operation.
To cope with a node error, the RDB system on the standby system is started up in advance and, if an error occurs on the node, failover of the operation can be completed in a short time. This is called the hot standby function.
