生成分布统计信息意味着给DB 2带来额外的、可观的开销，从而影响RUNSTATS命令的执行时间。
Generating distribution statistics means a significant, additional expense for DB2 and, therefore, influences the execution time of the RUNSTATS command.
如前所述，在使用RUNSTATS命令生成统计信息时，并不是总会收集分布统计信息。
As already mentioned, distribution statistics are not always collected when statistics are generated using the RUNSTATS command.
此外，如果需要收集CARS表中所有列的分布统计信息(频率统计信息和分位数统计信息)，那么可以执行以下命令。
If, in addition, distribution statistics (frequency and quantile statistics) should be collected for all columns of the table CARS, execute the following command.
如果它们以ras格式(可再用资源规格说明)进行分布，那么导入它们就需要运行RASImport命令了，并导入到RAS文件中。
If they are distributed in the RAS (Reusable Asset Specification) format, importing them requires running the RAS import command and browsing to the RAS file.
第三个命令抽取 15%的行，但是不收集分布统计信息，并对索引也应用了抽样，这不同于第一个命令和第二个命令。
The third command samples 15% of all rows, does not collect distribution statistics, and also applies sampling to indexes which the first and second commands didn't.
命令和分布式映射都是基于API的缓存。
Mercurial是一个小型但强大的分布式VCS系统，它很容易掌握，同时仍然提供VCS高级用户可能需要(或希望)使用的高级命令。
Mercurial is a small, powerful distributed VCS system that is easy to get started with, while still providing the advanced commands that VCS power users may need (or want) to use.
在分布式平台上，在mqm组中的用户可以通过发出setmqaut命令来授予或收回访问权限。
On distributed, users in the MQM group can issue the setmqaut command to grant or revoke access.
运行以下命令对HDFS分布式文件系统进行格式化。
Run the following command to format the Hadoop distributed file system to initialize.
使得所有的实例都包含给出的命令部署是很困难的，特别是在分布式系统中。
Deployment is hard if we have to make sure all instances contain a given command, especially in a distributed environment.
提出一种面向分布式系统的命令模式。
实验结果表明，半分布p2pbotnent命令与控制机制具有较高的效率和良好的韧性，符合新型P2PBotnet的要求。
According to the result of experiment, the partially decentralized P2P Botnet command and control mechanism has high efficiency and good resiliency. It settles for the need of new P2P Botnet.
说明：分布式数据管理（DDM）命令和1不支持。
