Action: If this error occurs while running RMAN, then it is an internal error and you should contact Oracle support.
ORA-19874: cannot finish multi-section restore to file是指Oracle数据库引擎出现的一种错误,代表无法将多段的备份恢复到文件中。这个错误可能会在备份恢复操作期间出现,原因可能是:
• 备份作业文件设定有异常;
• 恢复过程可能产生无效的备份归档文件;
• 文件路径设定有问题;
• 文件未完全恢复;
• RMAN本身被破坏;
• 恢复操作受到某种网络异常的影响等。
1)重新创建RMAN作业文件;
2)删除备份归档文件中的空块;
3)确认文件路径有效;
4)重新执行一次恢复操作;
5)如果RMAN报错,请重新升级或重新安装。
