ORA-19573: cannot obtain string enqueue for datafile string

ORA-19573: cannot obtain string enqueue for datafile string
Cause: The file access enqueue could not be obtained for a file specified in a backup, copy or restore operation. If the enqueue type shown is 'shared', then the file is the input file for a backup or copy. If the type is 'exclusive', then the file is the output file for a datafile copy or restore which is attempting to overwrite the currently active version of that file - in this case, the file must be offline or the database must be closed. If the type is 'read-only', then you are attempting to back up or copy this file while the database is in NOARCHIVELOG mode.
Action: Wait until the conflicting operation is complete, then retry the copy or backup. If the database is in NOARCHIVELOG mode, then all files being backed up must be closed cleanly.

ORA-19573：无法获取数据文件字符串的字符串入队,
.原因：无法获取在备份，复制或恢复操作中指定的文件的文件访问入队列。如果显示的入队类型是“shared”，则该文件是备份或副本的输入文件。如果类型为“exclusive”，则该文件是尝试覆盖该文件的当前活动版本的数据文件复制或恢复的输出文件 - 在这种情况下，文件必须脱机或数据库必须关闭。如果类型为“只读”，那么当数据库处于NOARCHIVELOG模式时，您正在尝试备份或复制此文件。,
.操作：等待冲突操作完成，然后重试副本或备份。如果数据库处于NOARCHIVELOG模式，则所有要备份的文件必须完全关闭。,
