摘　　要：为了保持雷达组网探测系统中大量的点迹,航迹数据和系统配置关键数据在系统使用中的实时性和连续性,同时为了确保数据库在设备频繁机动中的运行可靠性,文中着重研究了OracleRAC和Oracle Data Guard等数据库高可用性方法,并提出了雷达组网系统数据库的双机应用设计方案,从而实现了在没有磁盘阵列的情况下的数据库双机热备,使得雷达组网系统数据库具备了运行更为流畅,更轻巧灵活,以及适应机动的特点。In order to keeping on the real time and continuity of the plot, the track and the key configuration data in Radar-Netted Detection System, and in order to ensure the reliability of the database running during the frequently expedient, after a serious study on the database high availability method such as Oracle RAC or Oracle Data Guard, this paper presents a design concept of the dual-cluster of radar-netted detection system database. This concept realized the hot standby for dual-cluster without the RAID. Also it makes the radarnetted detection system database to have the features of running easily and smoothly and suiting the expedient.
