ORA-38783: Instance recovery required.

Cause: An attempt was made to create a restore point when the database is in mount mode but it was not shutdown cleanly before it was mounted. In order to create a restore point when the database is mounted, the database must be shutdown cleanly before it is mounted.

2. Open the database, shut it down cleanly, mount the database, and retry creating the restore point.

ORA-38783错误是一个发生在Oracle数据库的实例恢复(instance recovery)失败的错误。

官方解释

常见案例

一般处理方法及步骤

1.尝试重新启动实例，应该能恢复正常。

2.如果步骤1没有解决问题，可以通过查询V$instance_recovery来获取实例信息，判断是否存在恢复索引，而且锁定情况要处于unlock状态，重新执行恢复索引，恢复正常。

3.如果以上步骤仍无法解决，可以尝试通过alter database open resetlogs来完成恢复，但这样可能丢失相关更改。

4.最后一步，如果仍然失败，可以考虑实施备份与恢复。
