删除Oracle数据文件/临时文件
有些时候,想删除一个数据文件(临时文件),在10g之前的版本,要删除一个数据文件,必须删除该数据文件所属的表空间(特殊处理方法除外)。不太懂数据库的朋友直接os级别删除数据文件,导致数据库不能正常启动;稍微等点数据库的朋友,会先offline数据文件,然后os级别删除,但是这条数据文件的记录还保留在数据字典中,不爽(特殊处理办法见:清除离线数据文件记录)。在10g及其以后版本中,oracle提供了alter tablespace talbespace_name drop datafile/tempfile path/file_id进行删除某个数据文件
一、删除数据文件

三、注意事项
1、Oracle Database 10g Release 2及其以上版本
2、删除数据文件从数据库和系统
3、数据文件必须为空
4、数据文件不是对应表空间的最后一个
5、不能删除只读表空间中数据文件
6、不能删除system中数据文件
7、不能删除本地管理的offline表空间数据文件
