航班信息处理系统(简称FIPS系统),担负着民航空管电报分析及飞行计划处理、应答机分配等功能,对于管制飞行起着重要保障作用。近年来,随着航班量的增加,湛江空管FIPS系统的故障率有所提高,尤其是近期多次出现客户端访问超时、定时刷新失败等死锁现象。FIPS系统采用SQLSERVER2005作为其数据库,本文通过其附带的性能分析工具Profiler对FIPS系统中出现的死锁故障进行跟踪,通过对这些数据进行分析,得到了导致死锁的可能原因。然后给出了若干条处理建议,希望对运行现场类似故障有所帮助。
Flight Information Processing System (referred to as FIPS system), responsible for civil aviation telegraph analysis and flight planning processing, answering machine allocation and other functions, for the control of flights plays an important role in safeguarding. In recent years, with the increase of flight volume, the failure rate of Zhanjiang air traffic control FIPS system has been raised. In particular, many recent deadlocks such as client access timeout and regular refresh failure have occurred. The FIPS system uses SQLSERVER2005 as its database. This paper tracks the deadlock faults in FIPS system through its accompanying performance analysis tool Profiler. By analyzing these data, the possible causes of deadlock are obtained. Then gave a number of recommendations for treatment, hoping to help similar problems at the operation site.
