If you know that media recovery is required, you can start an instance, mount a database to the instance, and have the recovery process automatically start by using the STARTUP command with the RECOVER clause:
STARTUP OPEN RECOVER
If you attempt to perform. recovery when no recovery is required, Oracle Database issues an error message.
根据以上官方文档的解释
这个命令应该相当于
startup mount;
recover database;
alter database open;
目前没有环境,之后再进行测试
