1：周末遭遇停电，新配置的内网测试数据库active dataguard 环境自动关闭，今早启动主库后发现报错如下

2：第一反应先recover下database，再尝试拉起数据库，问题依旧

3：于是看alert日志和相关的trace文件，综合判断可能控制文件出现问题

4：于是生成控制文件trace控制脚本对控制文件执行恢复
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 | SQL> select open_mode from v$database; OPEN_MODE -------------------- MOUNTED SQL> alter database backup controlfile to trace as '/tmp/1.ctl' ; Database altered.

5：重建控制文件后，对数据库进行recover，成功打开数据库
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | SQL> alter database open; alter database open * ERROR at line 1 : ORA- 01113 : file 1 needs media recovery ORA- 01110 : data file 1 : '/u01/app/oracle/oradata/DB/datafile/o1_mf_system_8vpm8hf3_.dbf' SQL> recover database; Media recovery complete. SQL> alter database open; Database altered. SQL> select open_mode,database_role from v$database; OPEN_MODE DATABASE_ROLE -------------------- ---------------- READ WRITE PRIMARY |
6：通过观察alert日志，添加临时表空间数据文件

7：观察physical database，发现出现如下问题
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | [root@db2 ~]# su - oracle [oracle@db2 ~]$ sqlplus /nolog SQL*Plus: Release 11.2 . 0.1 . 0 Production on Mon Jun 17 17 : 18 : 50 2013 Copyright (c) 1982 , 2009 , Oracle.

8：于是关闭physical standby,在主库上启动system表空间的热备份，拷贝相应的文件至从库指定位置，重新同步正常
| 1 2 3 4 5 6 7 8 9 10 11 | SQL> shutdown immediate ORA- 01109 : database not open Database dismounted. ORACLE instance shut down. SQL> alter tablespace system begin backup; Tablespace altered.
