本文介绍了表空间仓库的概念及其组成。表空间仓库建立在文件组仓库之上，主要用于存放用于迁移或复制表空间所需的文件集合。其中包括不同版本的表空间集以及对应的Data Pump导出转储文件、日志文件和构成表空间的数据文件。

A tablespace repository is a collection of tablespace sets. Tablespace repositories are
built on file group repositories, but tablespace repositories only contain the files
required to move or copy tablespaces between databases. Different tablespace sets
may be stored in a tablespace repository, and different versions of a particular
tablespace set also may be stored. A version of a tablespace set in a tablespace
repository consists of the following files:
■ The Data Pump export dump file for the tablespace set
■ The Data Pump log file for the export
■ The datafiles that comprise the tablespace set[@more@]
