由上所知,预定的内存(性能监视器中的虚拟字节)将比提交的内存字节(性能监视器中的私有字节)大得多。
As you may have gathered from the above the reserved memory (virtual bytes in performance monitor) will be much larger than the committed bytes (private bytes in performance monitor).
DB 2fori 6.1最近的一个增强使得理解在SQL性能监视器中sql语句级使用优化器成为可能。
A recent enhancement to DB2 for I 6.1 makes it possible to understand the optimizer use at the SQL statement level within the SQL Performance Monitor.
当您选取了所有的选项并且决定了监视什么时,就可以通过选择ADD按钮来指示性能监视器开始监视此数据(图3)。
When all options have been selected and you have decided what is to be monitored, instruct the Performance Monitor to begin monitoring this data by selecting the ADD button (Figure 3).
中间的列显示在分析SQL性能监视器时观察到的值,最后一列定义输出的监视器文件中QVC43列显示的值。
The center column shows the values you would observe when analyzing the SQL Performance monitor and the last column defines the values which appear within the QVC43 column of the output monitor file.
本文解释如何收集SQL性能监视器,以及理解很多SQL查询在如何使用SQE,为什么其他sql语句继续使用CQE。
This article explains how to collect an SQL Performance Monitor and understand how many of the SQL queries are using SQE and why other SQL statements continue to use CQE.
另外还包含的工具有用于处理框架版本问题的应用配置工具,一个远程性能监视器,一个堆栈查看器和一个网络日志查看器等。
Also included is an app configuration tool for dealing with framework versioning issues, a remote performance monitor and heap viewer, and a network log viewer.
如果SQL性能监视器目标任务是一个特定的任务,并且该任务是由当前用户启动的,那么不需要 *JOBCTL 用户特殊权限。
If the SQL Performance Monitor target job was a specific job and that job was started by the current user, *JOBCTL user special authority is not required.
无论您是正在调查不同页宽的优点还是 XML性能的其他方面,很可能都要像对于关系数据一样使用DB2快照监视器。
Whether you are investigating the benefit of different page sizes or other aspects of XML performance, chances are you want to use the DB2 snapshot monitor as you would for relational data.
某团队成员很快添加了“监视器”,这降低一点性能,但是使用户能一直知晓长期运行的计算还需多少时间。
Someone on the team quickly hacks in a "monitor" that slows performance a bit but keeps the user informed about how much time remains for a long-running computation.
用于打开SQL语句事件监视器的选项并不实用,由于涉及的开销和潜在的性能损失,会导致一个高事务环境。
The option to turn on the SQL Statement event monitor is not practical because of the overheard involved and the potential performance penalty a high transaction environment could incur.
和对待关系数据一样,可以使用db 2中的标准诊断工具(例如visualexplain、db2exfmt和快照监视器)来调查XML性能。
The standard diagnostic tools in db2 such as visual explain, db2exfmt, and the snapshot monitor can be used for XML performance investigations just like for relational data.
一个Screen会话正在运行(尽管看不到),窗口A处于活动状态,它正在运行系统监视器top,每隔几秒刷新一次系统性能信息。
A Screen session is running (albeit unseen), and window a is active, running the top system monitor, which refreshes system performance information every few seconds.
如果使用长期历史,可以启动db2语句事件监视器来收集SQL事件监视器数据,并把收集的数据存储到PerformanceExpert服务器的性能数据库中。
If you use the long-term history, start a DB2 statement event monitor to collect SQL event monitor data and to store the collected data in the performance database of the performance Expert server.
性能改进中最近人注目的莫过于代码索引时间下降了50%,同时借助于本地的Linux文件系统监视器实现了Linux上更快的项目同步。
Performance improvements most notably include a 50% reduction in code indexing time, as well as faster project sync on Linux with a native Linux file system watcher.
