| Abstract: | The database disaster recover proposal is the key point to keep the HIS security and recoverable. Cluster based database disaster recover proposal provides the fault tolerance ability of mainframe. Replication based database disaster recover proposal provides a method to deploy a couple of warm standby mainframes at different area and makes handoff transparent when faults occurred. So it＇s a nice proposal to provide an uninterrupted environment of key applica-tions in hospital. |
