CORBA-Based High-Availability Marine Information Management Systems

More and more marine information management systems face a huge mass of data,complex environments and heterogeneous platforms.In this paper,a CORBA-based high-availability marine information management system is developed.This system hides the difference among platforms and achieves communications between heterogeneous nodes using the CORBA's feature of platform and language independency.Advanced Replication in the Oracle database is also used to provide hot standby and load balancing.This method improves the availability effectively.
