Application Research of Oracle RAC Dual-channel Technology in Meteorological Database
Zhengwei Guo · Computer Technology and Development · 2013
The application of meteorological data has become increasingly important in civil aviation,agricultural production,city weather and other fields.As the rapid development of meteorological service,new means are constantly emerging to obtain meteorological data,so a mass of meteorological data is produced.Now dual host mode in the hot standby architecture is faced with low system efficiency and cannot realize the load balance.For the problems of traditionally meteorological database systems in data throughput and high availability,present a system framework based on dual-channel technology in Oracle RAC,and test the system in the typical application scenarios.Test results indicate that this solution has a better load balance,which effectively improves the processing speed and efficiency of the system and ensures seamless connection under fault conditions.
