文档解释

ORA-19602: cannot backup or copy active file in NOARCHIVELOG mode

Cause: You tried to copy or backup a file that was not closed cleanly, and the database was in NOARCHIVELOG mode. This is not allowed because when restored, the file will require redo application before it is usable, and redo is not currently being saved beyond the contents of the online redo logs.

Action: Take the tablespace offline clean or close the database and retry the copy or backup.

ORA-19602：表示您尝试在NOARCHIVELOG模式下备份或复制正在使用的文件，不允许操作。
