ORA-01152: file string was not restored from a sufficiently old backup ORACLE 报错 故障修复 远程处理

文档解释

ORA-01152: file string was not restored from a sufficiently old backup

Cause: An incomplete recovery session was started, but an insufficient number of logs were applied to make the database consistent. This file is still in the future of the last log applied. The most likely cause of this error is forgetting to restore the file from a backup before doing incomplete recovery.

Action: Either apply more logs until the database is consistent or restore the database file from an older backup and repeat recovery.

ORA-01152是Oracle数据库报错代码，它表示从备份恢复文件时出现问题，具体的原因是文件不是从一个足够旧的备份中恢复的。
