ORA-01566：在ALTER DATABASE中指定的文件多次出现

官方解释

ORA-01566: file specified more than once in ALTER DATABASE statement

Cause: The same file was specified more than once in an ALTER DATABASE statement.

Action: Make sure that a file is only listed once in each statement.

常见案例

典型的ORA-01566错误可能是由于用户在ALTER DATABASE命令中指定了多个相同的数据文件时而发生的：

sql> alter database add alternate datafile ‘/u01/oradata/orcl/users02.dbf’ reuse;

ORA-01566: file specified more than once in ALTER DATABASE statement

正常处理方法及步骤

要解决这个错误，需要保证每个命令只列出一次文件名，而不是多次列出同一个文件：

SQL> alter database add alternate datafile ‘/u01/oradata/orcl/users02.dbf’ reuse;

数据库已更新。
