ORA-10458 ORA-01196故障处理

ORA-10458 ORA-01196

机房搬迁，测试环境直接关机，再次开机导致standby库报错如下：

操作系统均为centos6.5，是基于11.2.0.4的RAC TO DG

官方文档给出的解释:
ORA-10458: standby database requires recovery
Cause: A standby database was in a state requiring media recovery when an attempt was made to open the standby database.
Action: Perform the necessary recovery and open the standby database.

原因：强制关机导致日志记录的SCN与控制文件不符，不能完成checkpoint事件，需要进行介质恢复。

• 处理步骤：

–启动到mount状态

startup mount

–进行日志恢复

alter database recover managed standby database disconnect from session

–查看alert日志

当看到 in transit字样说明已经到最新日志了
Media Recovery Log /u01/app/arch/1_142_899302231.dbf
Media Recovery Waiting for thread 1 sequence 143 (in transit)

–取消日志恢复

alter database recover managed standby database cancel;

–打开数据库，并开启实时应用

alter database open;
alter database recover managed standby database using current logfile disconnect from session;

–查看是否实时应用，查看已经应用
