文档解释
ORA-01260: warning: END BACKUP succeeded but some files found not to be in backup mode
Cause: END BACKUP completed successfully for all files that were in online backup mode. However one or more modifiable files were found not to be in online backup mode. Backup of those files (if it was done) can be invalid and, if restored, can result in an inconsistent database.
Action: Check the alert log for a list of the files that were found not to be in backup mode. If there is a possibility that those files have been modified during online backup, then replace their backups with new ones.
ORA-01260警告消息指出,END BACKUP语句执行成功,但发现某些文件没有处于备份模式。这意味着数据库中的某些文件状态没有被改变,一旦改变,它们将被保存而不会被备份软件清空。
由于END BACKUP命令失败,因此数据库的备份将不完整,应该重新运行备份。另外,在此期间,需要确保没有任何系统发生变化。
官方解释

常见案例
当调用END BACKUP命令关闭该操作时,发现某些文件不在备份模式。此外,也可能由于系统分区错误而导致END BACKUP时某些系统文件不属于当前的备份模式。
正常处理方法及步骤
1.重新运行备份,以确保所有文件都被备份,且不干扰系统正常运行。
2.分析确定导致该问题的原因,可以采用一些诊断工具,例如ORADEBUG、TRACE等来检查系统运行状态,找出问题根源。
3.根据分析结果,修改文件备份模式,设置相应的访问控制,防止数据访问错误。
4.重新确认END BACKUP模式下的文件和数据的完整性并完成备份程序,回复数据正常工作状态。
