Finally , the most important reason for dynamically generating EWU values is data center automation .

最后，动态地生成EWU值的最重要的原因是数据中心自动化。

Here is an example of the EWU value calculation using AIX commands and syntax

下面是使用AIX命令和语法计算EWU值的示例

This requires a mechanism that will generate the same EWU value across heterogeneous platforms .

这需要一种跨异类平台生成相同EWU值的机制。

The EWU value translated into the desired output counting base and number of output characters .

按照所需的输出计数基数和输出字符数转换后的EWU值。

Using the previously generated CRC cksum value , calculate the EWU value

使用前面生成的CRC校验和值计算EWU值

An EWU identifier is any parameter that has a single unique value across the entire enterprise .

EWU标识符是指在整个企业范围内具有单一值的任何参数。

The best solution is to not use spreadsheets or databases for mapping EWU values to critical configuration parameters .

最好的解决方案是不使用电子表格或数据库把EWU值映射到关键配置参数。

By generating the EWU value , the need for maintaining spreadsheets and databases is eliminated .

通过生成EWU值，就不再需要维护电子表格或数据库。

Here is an explanation of the components of the EWU value calculation using the CRC cksum command

下面解释一下使用CRC校验和命令计算EWU值所需的各个成分

The best solution is to dynamically generate the EWU value on an as-needed basis from the critical configuration parameter .

最好的解决方案是，根据需要从关键配置参数动态地生成EWU值。

One problem experienced by most systems administrators when attempting to implement EWU identifiers is how to track and document them .

在试图实现EWU标识符时，大多数系统管理员遇到的一个问题是如何跟踪和记录它们。

A script for generating the EWU value should be written as a function and included in an organization 's standard set of shell functions .

生成EWU值的脚本应该编写为一个函数，并把它包含在组织的标准shell函数集中。

If a shell script is used to generate the EWU value , then it must be able to accept any given input string of characters .

如果使用shell脚本生成EWU值，那么脚本必须能够接受任何输入字符串。

Although compiled programs are generally much faster than scripts , speed is not the primary concern when creating a mechanism for generating EWU values .

尽管编译的程序的运行速度通常比脚本快得多，但是对于生成EWU值的机制，速度并不是主要关注点。

A necessity for designing and deploying large environments is to ensure that critical configuration parameters have Enterprise-Wide unique ( EWU ) identifiers .

设计和部署大型环境的一个必要条件是，要确保关键的配置参数具有Enterprise-Wideunique（EWU）标识符。

A command-line option is provided to minimize the output record to only display the EWU value for each character string provided on the command line .

一个命令行选项可以缩减输出记录，只显示在命令行上提供的每个字符串的EWU值。

Another benefit of using a standardized mechanism of generating EWU values is that it eliminates the need for storing these values in spreadsheets or databases .

使用标准化机制生成EWU值的另一个好处是，不再需要把这些值存储在电子表格或数据库中。

The proportion of actual EWR of the Haihe River during 1999-2002 revealed that the EWU has not been satisfied .

然后计算了1999-2002年海河实际生态用水比例，表明生态用水一直没有得到满足。

The reason for using a shell script is to be able to consistently generate the same EWU identifier value for any given string on any UNIX system .

使用shell脚本的原因是，能够在任何UNIX平台上为任何字符串生成相同的EWU标识符。

This enables systems administrators to easily incorporate this function into their shell scripts and ensure EWU values are being generated in a consistent and repeatable manner .

这使系统管理员能够轻松地把这个函数合并到自己的shell脚本中，确保以一致且可重复的方式生成EWU值。

The reasons for using a script mechanism , such as mkewuid , to generate EWU values are numerous and important for the operation and management of a modern data center environment .

使用mkewuid这样的脚本生成EWU值有许多原因，这对现代数据中心环境的操作和管理非常重要。

EWU identifiers are required to eliminate the occurrence of duplicate values that will interrupt and delay the processes of disaster recovery , high availability , and virtualization .

EWU标识符可以消除重复的值，这些重复的值会破坏和拖延灾难恢复、高可用性和虚拟化过程。

Considering the coordination with the social economic development of the Haihe area , the reasonable proportion of Haihe EWU should be maintained within threshold value of 16 % ~ 46 % .

最后通过与海河社会经济发展的协调，确定海河河流生态系统的合理生态用水比例应维持在（16%～46%）的阈值区间内。

Designing these resources with EWU values eliminates the possibility of conflict during automated or manual fail-overs , high-availability operations , and disaster-recovery testing or implementation .

通过用EWU值定义这些资源，可以在自动或手工故障转移、高可用性操作和灾难恢复测试或实现期间消除冲突。

In normal usage , this script function would normally be called from a shell script written by a systems administrator , and used to calculate an EWU value for a single character string .

通常，在系统管理员编写的shell脚本中调用这个脚本函数，用它为单一字符串计算EWU值。

The previous technique will generate a unique identifier for any user-supplied character string ; however , it is somewhat cumbersome to issue this list of commands every time an EWU value is needed .

前面的技术可以为任何用户提供的字符串生成惟一的标识符；但是，在每次需要EWU值时都执行这一系列命令比较麻烦。

Rapid identification of areas suffering serious Eco-environmental Water Deficit ( EWD ) and dynamic assessment of Eco-environmental Water Use ( EWU ) are of significance to ecological construction and sustainable utilization of water resources in a catchment .

快速识别流域内生态缺水严重的区域、动态评估生态用水状况对流域生态环境建设和水资源优化配置具有重要意义。
