其目标是允许DB2确定工作负载需要哪些统计信息,并定期在后台自动运行RUNSTATS实用程序,以便按需更新统计信息。
The objective is to allow DB2 to determine which statistics are required by the workload, and automatically run the RUNSTATS utility in the background periodically to update statistics as needed.
因此,当您最开始在系统上加载负载之后,或者无论何时数据库中的数据量剧烈变化,都应该通过运行DB2RUNSTATS实用程序更新统计数据。
Therefore, after initially putting load on your system, or whenever the data volume in the database changes significantly, you should update the statistics by running the DB2 RUNSTATS utility.
批处理和实用程序往往是各种系统资源的消费大户,一旦它们挤在一起,常常会使工作负载逐步上升。
Batch and utilities tend to be large consumers of all kinds of system resources, and when pressed, may often escalate the workload.
如果查询工作负载导致创建许多TEMP表(您可以通过使用解释实用程序来确定)时除外。
The exception would be if the query work load results in many TEMP tables being created (you can determine this by using the explain utility).

The utility bases its load balancing around the concept of channels.
DB 2提供了一个名为Design Advisor的实用程序,可以用它来为特定的查询或工作负载推荐索引。
DB2 provides a utility called Design Advisor which you can use to recommend indexes for a particular query or workload.
使用这个实用工具,您研究了tcp和udp工作负载优化,同时还了解了一些其他值得关注的参数。
Using this utility, you explored TCP and udp workload tuning while also learning some other noteworthy parameters.
如果您想对这项工作进行负载均衡,或者为连接db2的应用程序提供备用路径,那么Balance实用程序可以满足您的要求。
If you wish to load balance this work or provide an alternate path for connecting applications, then the balance utility may suit your needs.
util_impact_lim参数是指允许所有已调整实用程序对于实例的工作负载产生影响的百分比。
The util_impact_lim parameter is the percentage of allowable impact that all throttled utilities can have on the instance workload.
执行Domino服务器性能测试依赖于模拟真实用户负载的能力。
Conducting Domino server performance tests depends largely on the ability to simulate a realistic user load.
Apache的访问日志就是一个好例子;负载大的Web服务器可能在几分钟内生成数以千计的日志消息,每个消息都提供详细的信息,这其实用处不大。
Apache's access log is a good example-heavily used Web servers can generate thousands of log messages in a few minutes, each of which provides detailed information that isn't really useful.
