一.2 前言部分
一.2.1 导读和注意事项
各位技术爱好者，看完本文后，你可以掌握如下的技能，也可以学到一些其它你所不知道的知识，~O(∩_∩)O~：
① 主库丢失归档，物理DG的恢复
② 其他常用SQL语句
Tips：
① 若文章代码格式有错乱，推荐使用QQ、搜狗或360浏览器，也可以下载pdf格式的文档来查看，pdf文档下载地址：http://yunpan.cn/cdEQedhCs2kFz （提取码：ed9b）
② 本篇BLOG中命令的输出部分需要特别关注的地方我都用灰色背景和粉红色字体来表示，比如下边的例子中，thread 1的最大归档日志号为33，thread 2的最大归档日志号为43是需要特别关注的地方；而命令一般使用黄色背景和红色字体标注；对代码或代码输出部分的注释一般采用蓝色字体表示。

一.3 故障分析及解决过程
一.3.1 故障环境介绍
| 项目 | source db | PHYSICAL STANDBY |
| db 类型 | RAC | RAC |
| db version | 11.2.0.3 | 11.2.0.3 |
| db 存储 | ASM | ASM |
| OS版本及kernel版本 | AIX 64位 6.1.0.0 | AIX 64位 6.1.0.0 |
一.3.2 故障发生现象及报错信息
由于客户这边有N套库，我过来时间短，没有完全整理，昨天对一套rac执行健康检查的时候发现带有一套物理DG,但是DG库不同步，而且同步的日志号已经断档很久了，于是决定把这套DG恢复一下，下边简单记录一下。
数据库信息：
DG库信息：
| THREAD# | DEST_ID | DEST_NAME | TARGET | DATABASE_MODE | DB_UNIQUE_NAME | DESTINATION | CURRENT_SEQ# | LAST_ARCHIVED | APPLIED_SEQ# |
| 1 | 1 | LOG_ARCHIVE_DEST_1 | LOCAL PRIMARY | OPEN | NONE | /archive/arch | 14311 | 14310 | |
| 1 | 2 | LOG_ARCHIVE_DEST_2 | PHYSICAL STANDBY | OPEN_READ-ONLY | oraNETR | oraNETR | 14311 | 14310 | 968 |
| 2 | 1 | LOG_ARCHIVE_DEST_1 | LOCAL PRIMARY | OPEN | NONE | /archive/arch | 13403 | 13402 | |
| 2 | 2 | LOG_ARCHIVE_DEST_2 | PHYSICAL STANDBY | OPEN_READ-ONLY | oraNETR | oraNETR | 13403 | 13402 | 644 |
可以看到实例一当前是14311，但是DG库才应用到968，而实例二当前是13403，DG应用到644，下边着手恢复备库，恢复的原理可以参考之前的文档 【DATAGUARD】物理dg在主库丢失归档文件的情况下的恢复(七)： http://blog.itpub.net/26736162/viewspace-1780863/ 。
一.3.3 故障分析及解决过程
在主库看了下，968、644的日志早都不见了，没办法只能对主库进行基于SCN号的增量备份：
先查找最小的scn号：
SELECT (SELECT MIN(d.CHECKPOINT_CHANGE#) FROM v$datafile d) datafile_scn,
(SELECT MIN(d.CHECKPOINT_CHANGE#)
FROM v$datafile_header d
WHERE rownum = 1) datafile_header_scn,
(SELECT current_scn FROM v$database) current_scn,
(SELECT min(b.NEXT_CHANGE#)
FROM v$archived_log b
WHERE b.SEQUENCE# in (968,644)
AND resetlogs_change# =
(SELECT d.RESETLOGS_CHANGE# FROM v$database d)) NEXT_CHANGE#
FROM dual;
我们取12232942713886为备份的SCN号：
备份：
run
{
allocate channel d1 type disk;
allocate channel d2 type disk;
allocate channel d3 type disk;
allocate channel d4 type disk;
backup as compressed backupset incremental from SCN 12232942713886 database format '/archive/standby_new_%d_%T_%U.bak' include current controlfile for standby filesperset=5 tag 'FOR STANDBY new';
release channel d1;
release channel d2;
release channel d3;
release channel d4;
}
将日志传递到备库：

从健康检查中可以找到最新的控制文件备份集名称是/archive/standby_ORANET_20160131_0rqsnulk_1_1.bak，我们在备库首先启动到nomount状态，然后恢复控制文件：

cp +DATA/oranetr/controlfile/control01.ctl +DATA/oranetr/controlfile/control01.ctl_bk
restore standby controlfile to '+DATA/oranetr/controlfile/control01.ctl' from '/archive/standby_ORANET_20160131_0rqsnulk_1_1.bak';

很明显，控制文件是从主库恢复过来的，但是ASM的文件名是不一样的，所以报错，那么要做的就是重命名备库的数据文件名，用editplus或UE的列模式来编辑代码：
col name format a60
set line 9999 pagesize 9999
SELECT a.FILE#, a.NAME,a.CHECKPOINT_CHANGE#,a.LAST_CHANGE#,status FROM v$datafile a;
alter system set standby_file_management=manual;
alter database rename file '+DATA/oranetr/datafile/system.260.873307133' to '+DATA/oranetr/datafile/system.293.876478571' ;
alter database rename file '+DATA/oranetr/datafile/sysaux.261.873307151' to '+DATA/oranetr/datafile/sysaux.291.876478569' ;
。。。。。。。。。。。。。。。。。。。
alter database rename file '+DATA/oranetr/datafile/bocnet_tbs.338.1163840135' to '+DATA/oranetr/datafile/bocnet_tbs.347.876559543';
alter database rename file '+DATA/oranetr/datafile/bocnet_tbs.339.1163840135' to '+DATA/oranetr/datafile/bocnet_tbs.348.876559545';
alter database rename file '+DATA/oranetr/datafile/bocnet_tbs.340.116384013' to '+DATA/oranetr/datafile/bocnet_tbs.349.876559545';
重命名数据文件完成后再次执行恢复操作即可，恢复的过程中我们可以通过如下的SQL语句来查看恢复的进度：
SELECT a.USERNAME,
(SELECT upper(nb.OSUSER) FROM v$session nb WHERE nb.SID = a.sid) OSUSER,
(SELECT nb.sid || ',' || nb.SERIAL# || ',' || pr.SPID
FROM v$process pr, v$session nb
WHERE nb.PADDR = pr.ADDR
and nb.sid = a.SID
and nb.SERIAL# = a.SERIAL#) session_info,
a.target,
a.opname,
to_char(a.START_TIME, 'YYYY-MM-DD HH24:MI:SS') start_time,

一.3.3.3 主备添加standby日志

恢复完成后发现主备库都没有standby日志，然后添加一下日志:
alter database add standby logfile thread 1 group 7 size 1073741824 ,group 8 size 1073741824 ,group 9 size 1073741824,group 10 size 1073741824 ;

一.3.3.4 再次健康检查
再次执行健康检查的时候发现DG库已经正常了。

一切正常，测试一下实时同步的功能也是可以的。
一.4 故障处理总结
文章写的比较简单，主要是因为之前有过类似的文章，但这篇是基于RAC环境的，对控制文件的处理稍有不同而已，详细可以参考：http://blog.itpub.net/26736162/viewspace-1780863/。
