11GR2RAC丢失OCR和CONTROLFILE重建恢复过程

今天准备用自己的rac虚拟机做点实验的，可是虚拟机拉起来时，频频报错，估计好久不用了（前一阵子有厂商来推销虚拟化全在那上做测试了），挨个检查发现是OCR出故障了，没办法重建下吧，顺便记录下重建的过程

1.使用orccheck命令报错

[root@rac1 ~]#ocrcheck

PROT-602: Failedto retrieve datafrom the cluster registry

PROC-26: Errorwhile accessing the physical storage

2.使用ocrconfig-restore恢复仍然报错

[root@rac1 rac-cluster]#ocrconfig-restore/u01/app/11.2.0/grid/cdata/rac-cluster/backup00.ocr

PROT-35: The configured OCR locations arenot accessible.

3.强制停掉两个节点的crs（两个节点都要执行）

[root@rac1 rac-cluster]#crsctl stop crs-f

CRS-2791:Starting shutdown of Oracle High Availability Services-managed resources on 'rac1'

4.在节点一上已独占方式启动(只启动ASM实例但不启动CRS)

[root@rac1 ~]#crsctl start crs-excl-nocrs

CRS-4123:Oracle High Availability Services has been started.

CRS-2672:Attempting to start 'ora.mdnsd' on 'rac1'

5.重建原votedisk所在的磁盘组

[root@rac1 ~]# su- grid

[grid@rac1 ~]$ sqlplus/as sysasm

SQL*Plus: Release11.2.0.4.0 Productionon Sun Feb2800:09:322016

Connectedto:

Diskgroup created.

6.使用最新的OCR备份进行恢复

[root@rac1 ~]#ocrconfig-restore/u01/app/11.2.0/grid/cdata/rac-cluster/backup00.ocr

[root@rac1 ~]#ocrcheck

Statusof Oracle Cluster Registryisas follows :

7.恢复votedisk

[root@rac1 ~]#crsctl query css votedisk

Located0 votingdisk(s).
[grid@rac1 ~]$ crsctl replace votedisk +SYSTEMDG

Successful additionof votingdisk a0e3b9c0c5934f79bf67aa783618b59d.

Notes：如果在恢复时遇到如下错误：

[grid@rac1 ~]$crsctlreplace votedisk +SYSTEMDG

CRS-4602: Failed27toadd votingfile a0e3b9c0c5934f79bf67aa783618b59d.

9.由于启动较慢，过几分钟查看状态

[root@rac1 ~]# crs_stat-t

10.但是在启动db的时候报错了。。。

PRCR-1079 : Failedto start resource ora.orcl.db

CRS-5017: The resource action "ora.orcl.db start" encountered the following error:

--查看了下trace发现SYSTEMDG中的控制文件没了，装RAC的时候就没规划好，导致控制文件放到了votedisk里，但是SYSTEMDG刚刚被重建了，所以丢了

11.将数据库启动到nomount阶段

[grid@rac1 trace]$srvctl startdatabase-d orcl-o nomount

12.在节点一上使用rman恢复一份控制文件到SYSTEMDG上

[oracle@rac1 ~]$ rman target/

Recovery Manager: Release11.2.0.4.0- Productionon Sat Feb2723:53:352016

connectedto targetdatabase: ORCL (not mounted)

RMAN>restore controlfileto'+SYSTEMDG'from'+DATADG/orcl/controlfile/current.260.901699963';

channel ORA_DISK_1: copied controlfile copy

13.已恢复好的控制文件路径和名称

ASMCMD> pwd

+systemdg/orcl/CONTROLFILE

ASMCMD> ls

current.261.904953225

14.节点一上登陆db，修改control_files参数

[oracle@rac1 ~]$ sqlplus/as sysdba

SQL*Plus: Release11.2.0.4.0 Productionon Sat Feb2723:55:092016

Connectedto:

System altered.

15.重启数据库，并检查数据库状态

[grid@rac1 trace]$srvctl stopdatabase-d orcl

[grid@rac1 trace]$srvctl startdatabase-d orcl

[grid@rac1 trace]$srvctl statusdatabase-d orcl

Instance orcl1is runningon node rac1

Instance orcl2is runningon node rac2

16.保险起见，查看两个节点上的控制文件参数是否正确

[oracle@rac1 ~]$ sqlplus/as sysdba

SQL*Plus: Release11.2.0.4.0 Productionon Sat Feb2723:58:472016
