Meteorological data switching system

摘要

The Meteorological Agency has installed the Local Automated Data Editing and Switching System (L-ADESS) to exchange various meteorological data. This system is required to provide high reliability. Recently, the need has arisen for higher system performance due to an increase in the amount of meteorological data and the introduction of open platforms.To satisfy this need, we established a duplex system with UNIX servers and middleware for a high-availability system. In the event that the working server is out of order, the standby server will take its place in the same operational condition. Thissystem demonstrates the valuable role that UNIX servers can play in ahigh-availability system.
