重大危险源信息系统的研究与实践

在重大危险源信息系统长期实践的基础上，针对SQL server 2000＋Tomcat系统，探讨了提高系统稳定性、保证系统安全的方法。一方面从数据设计保证系统规范合理，研究SQL server数据性能优化，数据库安全配置，数据库备份与日志管理；另一方面讨论应用系统部署，通过对Tomcat服务器的外部环境和自身进行优化，防止了内存泄露和不稳定现象的发生，并分析Tomcat入侵途径，探讨了预防黑客攻击的方法。这些方法在很多实践中取得了满意的效果，并对一般信息系统建设也有很强指导意义。

Research and practice on the information system of major hazard installation

On the basis of long-term practice for major hazard information systems with SQL server 2000 add Tomcat, the methods to improve system stability and ensure system security were discussed. On the one hand, the data system design to ensure a reasonable standard was concerned. The data on SQL server performance optimization was researched while database security configuration and database backup and log management were also studied. The other hand, the deployment of application systems was analysis. The external environment and itself optimization were applied to prevent memory leakage and the instability occurrence. Also some techniques to prevent hacker attacking were presented by means of analyze the Tomcat invasion pathway. These methods have achieved a lot of practical satisfactory results and will be benefit to general information system.
