文档解释

ORA-01194: file string needs more recovery to be consistent

Cause: An incomplete recovery session was started, but an insufficient number of logs were applied to make the file consistent. The reported file was not closed cleanly when it was last opened by the database. It must be recovered to a time when it was not being updated. 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 file is consistent or restore the file from an older backup and repeat recovery.

ORA-01194错误是由于数据库文件需要更多的恢复来确保其一致性而引起的。

ORA-01194的官方解释如下：

ORA-01194 表示要使文件一致，需要执行更多的恢复操作。

常见案例

在Oracle备份中，当用户尝试执行恢复时，此错误可能会出现，而这意味着恢复到完整性，所需的恢复操作还不够完整。

正常处理方法及步骤

1.查询导致ORA-01194的用户尝试的备份恢复操作的注释。

2.分析原因，通常原因是典型的ORA-01194发生在DBA用于从另一台机器复制文件时。

3.使用带有参数recover的RECOVERDATABASE命令重新恢复数据库，以确保文件一致性，可以使用语句“RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL”执行恢复。

4.重新启动数据库。

5.检查数据库状态，可以使用命令“SELECT STATUS FROM V$INSTANCE”来查询数据库状态。
