查看物理恢复结果

恢复结束后，可以通过视图查看物理恢复结果。

操作步骤

1. 使用 root 用户登录集群的 sys 租户。

2. 待恢复完成后，您可以执行以下语句，查看集群的恢复任务结果。

   obclient [(none)]> SELECT * FROM oceanbase.CDB_OB_RESTORE_HISTORY\G
   

   查看结果示例如下：

   1 row in set
   

   CDB_OB_RESTORE_HISTORY 视图中各字段基本与 CDB_OB_RESTORE_PROGRESS 相对应。其中，COMMENT 用于记录任务失败时的相关错误信息。

   如果恢复失败，您可以通过删除租户的方式来取消本次恢复，具体操作请参见 取消恢复。

后续操作

物理恢复执行成功后，恢复后的租户均为备租户，您可执行如下操作:

• 执行 recover 命令, 作为备租户继续从源租户回放日志, 具体操作参见 备租户日志回放。

• 执行备切主命令，将备租户转换为主租户，具体操作参见 备租户转为主租户。
