The TABLESPACES parameter specifies that all tables in the tablespace be
exported to the Export dump file. This includes all tables contained in the list
of tablespaces and all tables that have a partition located in the list of
tablespaces. Indexes are exported with their tables, regardless of where the
index is stored. You must have the EXP_FULL_DATABASE role to use TABLESPACES to
export all tables in the tablespace.When TABLESPACES is used in conjunction with
TRANSPORT_TABLESPACE=y,you can specify a limited list of tablespaces to be
exported from the database to the export file.
1. 导出在指定的表空间的表
2. 如果某张表是分区表, 分区不在同一个表空间中 ,
但在指定的表空间中有一个分区的话 , 导出这个分区
3. 导出表的索引 , 不管索引存储在什么位置
4. 需要有EXP_FULL_DATABASE角色,否则报EXP-00023错误
5. 当该参数与TRANSPORT_TABLESPACE一起使用时 , 可以指定多个表空间(但在测试时
没有指定TRANSPORT_TABLESPACE , 也可以导出几个表空间)
