Conventional water quality monitoring methods, always includes such steps as artificial sampling, laboratory analysis and evaluation etc, which have long period, high cost and heavy workload of monitoring, and the monitoring results only represent the local situation of water pollution. 常规的水质监测方法采用人工取样、实验室分析评价,监测周期长、成本高、工作量大,且监测结果只具有局部代表意义。
DB2 Optimization Expert for z / OS : Provides an environment for performing workload and query monitoring and tuning tasks when accessing DB2 for z / OS databases. DB2OptimizationExpertforz/OS:在访问DB2forz/OS数据库时提供了一种可以执行工作负载、监视查询和调优任务的环境。
But the workload of each monitoring point increases due to the syndrome surveillance. The schools and the community health service centers can accept these workload and they are also relatively confident of the correctness of report data and monitoring quality. 但是,开展症状监测增加了各监测点的工作量,其中学校及社区卫生服务中心认为这样的工作量能够接受,且对上报数据的正确性、监测质量较有信心。
If your application happens to have a high update workload, the database snapshot monitoring may reveal a large number of log pages read. 如果您的应用程序碰巧具有高更新的工作负载,那么数据库快照监控就可以暴露大量的日志页面读。
The key work of paper can be summarized as follows : Firstly, Proposed a middleware model of workload adaptation database system, the model consisted by five components, they are interceptor, workload characterization module, system monitoring module, repository and workload control module. 主要工作如下:1.提出了负载自适应控制中间件模型,该模型由拦截器、负载特征化模块、系统监测模块、知识库和负载控制模块五部分组成。
