更新的AIX系统标识。
您可以通过几种方法来收集系统标识数据。
You can collect system identification data in several ways. To uniquely identify a machine or a partition, it is necessary to have one or more of the following elements.
用于检查系统标识的其他命令和系统接口。
Other commands and system interfaces for examining the system identification.
还可以通过一组系统API来查询系统标识信息。
It is also common to query the system identification information through a set of system apis.
系统标识符在其他系统中惟一地标识产品。
System identifiers uniquely identify products in other systems.
getSystemId返回当前文档事件的系统标识。
GetSystemId returns the system identifier for the current document event.
目前的AIX 5.2和AIX 5.1系统标识命令。
生成唯一系统标识符的要求也相应地有所提高。
The requirement for generating unique system identifiers has also increased accordingly. The following is a requirement list to properly support the generation of system identifiers
表2介绍了一些系统中唯一系统标识符的生成方式。
Table 2 shows the way in which a unique system identifier is generated for some systems.
AIX5lVersion 5.3系统标识编程接口发生了变化。
The programming interface for system identification has changed for AIX 5l Version 5.3.
例外情况是目录文件（在另一章中讨论），它将公共标识解析成系统标识。
The exception is catalog files (covered in a different chapter), which resolve public identifiers to system identifiers.
原始设备制造商(OEM)系统可以使用本文作为参考，以生成他们自己的系统标识。
Original equipment manufacturer (OEM) systems might use this article as a reference for their own system identification generation.
第二种形式是系统标识符，用于记录其他存储产品的应用程序中使用的主键。
The second form is system identifiers for recording the primary key used in other applications that store the product.
值“TTTTCCSSSSS”表示不需要型号号码来生成唯一系统标识符。
The value "TTTTCCSSSSS" means that the model number is not required to generate a unique system identifier.
nid和xutsname . longnid包含了原始的和新的系统标识信息。
Xutsname.nid and xutsname.longnid contain the original and new system identification information.
值“TTTTSSSSS”表示不需要型号号码和生产厂家来生成唯一系统标识符。
The value "TTTTSSSSS" means that the model number and plant of manufacture are not required to generate a unique system identifier.
要获取唯一系统标识符，可以使用带- Mu或- MuL标志的uname命令。
To get a unique system identifier, use the uname command with the -mu or -mul flag.
您也需要考虑，对于相同的外部实体引用，两个DTD实际指定的可能是不同的公用和系统标识。
You also need to consider that two DTDs may actually specify different public and system IDs for the same external entity reference.
值“SSSSS”表示不需要计算机类型、型号号码和生产厂家来生成唯一系统标识符。
The value "SSSSS" means that the machine type, model number, and plant of manufacture are not required to generate a unique system identifier.
对于AIX5L 来说，总的方向是从32 位系统标识符迁移到 64位系统标识符。
The general direction for AIX 5L is to migrate from 32-bit system identifiers to 64-bit system identifiers. To prepare for this switch, applications should do the following
相反，可以使用其投影其他反映系统标识的标识，而不要对人类最终用户的标识进行投影。
Instead, you can use them to project other identities that reflect system identities, rather than human end users' identities.
DTD在系统标识中由URL表明，后者是所有DocBook定义所在的地方。
The DTD is indicated in the system identifier by a URL, which is where all the DocBook definitions are located.
使用这种方法，可以“缩短”处理进程，并向给定的公共标识或系统标识提供您自己的数据。
In this way, you can "short circuit" the process and supply your own data for a given public or system ID.
实际的应用程序可能会使用符号标识符来定位适当的内容处理程序并使用实体的系统标识符作为其输入。
A real-world application might use the notation identifier to locate the appropriate content processor and use the entity's system identifier as its input.
Matthew cronk是aix核心开发人员，是IBM AIX操作系统标识设计规范的拥有者。
Matthew Cronk, AIX Kernel Developer, is the owner of the design specification for the IBM AIX operating system identification.
Johno'Quin是杰出工程师和AIX架构师，是系统标识方案的设计者及相关算法的开发人员。
John o 'quin, Distinguished Engineer, AIX Architect, is the designer of the system identification plan and also the developer for the algorithms involved.
譬如，清单8显示的DTD非常类似于清单6，但对于NHLCopyright引用指定了不同的系统标识。
For example, Listing 8 shows a DTD very similar to Listing 6, but with a different system ID specified for the NHLCopyright reference.
基于更新的设计，为 /usr/bin/uname命令添加了两个新的标志，以便可靠地生成唯一系统标识。
Two new flags have been added to the /usr/bin/uname command based on the updated design to reliably generate unique system identification. These identifiers are for new hardware only
比如，给定一个DTD的系统标识符和公共标识符，实体目录可用于规定XML处理程序从哪里加载dtd。
For example, an entity catalog can be used to specify the location from which an XML processor loads a DTD, given the system and public identifiers for that DTD.
尽管可以使用uname - m，但不建议这样做，因为对于唯一系统标识来说，5位数字的序列号并非总是足够的。
Although uname -m is available, it is not recommended, since the five-digit sequence number is not always sufficient for unique system identification.
