oracle表空间的传输步骤如下： 1.检验表空间的自包含性：
SQL>exec dbms_tts.transport_set_check('account_data',true); SQL>select * from transport_set_violations;
--如果未选定行，说明表空间是自包含的。否则不能传输。
2.将表空间置为只读：
SQL>alter tablespace tablespace_name read only;
3.卸出表空间：
$exp transport_tablespace=y tablespaces=tablespace_name file=xxx
4.复制数据文件和卸出文件，并将这些文件复制到另一台服务器。
5.使用IMP装入表空间：
$imp transport_tablespace=y datafiles='xxx.dbf' tablespaces=tablespace_name file=xxx.dmp
6.将表空间改为读写状态：
SQL>alter tablespace tablespace_name read write;
表空间传输的一些限制：需要两个平台一致，必须有相同的字符集和多语言字符集。要求两个实例的db block size 大小相等，如不相等则需要兼容9.0以上等。
我在windows平台和solaris平台传输表空间的时候就遇到了以上问题，摘录如下：
