内部的服务器属性是决定联邦系统与远程数据源各自所支持的功能的不同之处的关键因素。
Internal server attributes are key factors in determining the differences in functionality that can be supported at the federated system compared with remote data sources.
为了处理该查询，DB 2查询编译器查阅DB 2联邦数据库系统编目中的信息以及数据源包装器模块中的信息。
To process the query, the DB2 query compiler consults information in the DB2 federated database system catalog and the data source wrapper modules.
适配器提供对数据库、文件、消息传递系统、企业应用程序和其他数据源和目标的访问。
The adapters provide access to databases, files, messaging systems, enterprise applications, and other data sources and targets.
在系统实际使用NIS数据库信息前，必须对系统用于查找信息的数据源进行重新配置。
Before the systems actually use the NIS database information, you must reconfigure the data sources used by the system to look up information.
如果在导入时，在目标系统上不能找到数据源，规则应该被绑定到这个没有绑定的源数据上。
If a data source is not found on the target system at the time of the import, the rules that should be bound to this data source are unbound.
数据源属性重写了系统属性。
将磁盘的模式从复制原始数据中心的数据更改为作为操作系统映像的数据源使用。
Change the mode of the disks from replicating data from the original data center to being the source of the data for the operating system images.
