PRIMECLUSTER Installation and Administration Guide 4.1 (for Solaris(TM) Operating System)

15.1.1 Overview of Cluster System Support

The Interstage Application Server Enterprise Edition supports two modes: Namely, 1:1 standby, which is a so-called hot standby system in which the operation is automatically taken over by the standby node if a failure occurs in the OPERATING node; and mutual standby, in which two nodes perform each operation and, if a failure occurs on one node, the other node takes over the operation.

With the Interstage Application Server Enterprise Edition, operating on the cluster system allows high-speed switching to another server to take over the operation even in the event of a failure. The client can continue the transaction through reconnect processing and can minimize downtime.
