症状
在将所有表和索引移动到另一个表空间后，我执行部分复制，跳过旧的表空间。
对新复制数据库的查询报告一个属于被跳过表空间的数据文件的错误：
ORA-00376: file 18 cannot be read at this time
ORA-01111: name for data file 18 is unknown - rename to correct file
ORA-01110: data file 18: '/u01/app/oracle/product/10.2.0/db_1/dbs/MISSING00018'
更改
原因
部分RMAN 复制失败，显示如下：

在被跳过的表空间中有依赖性。
解决方案
确保在被跳过的表空间中没有依赖性。依赖性包括物化视图，和高级排列表advanced queuing tables。
否则，在辅助站点，drop该表空间中所有依赖性，并最终drop在辅助站点的表空间。
