--执行手工OCR的备份
[root@rac1 rac-cluster]# ocrconfig -manualbackup 


--查看ocr的手工备份：
[root@rac1 rac-cluster]# ocrconfig -showbackup manual


vmac2     2016/03/08 10:21:50     /g01/11ggrid/app/11.2.0/grid/cdata/vmac-cluster/backup_20160308_102150.ocr


vmac2     2016/03/07 11:22:49     /g01/11ggrid/app/11.2.0/grid/cdata/vmac-cluster/backup_20160307_112249.ocr




用grid用户执行：
$ cd $GRID_HOME/gpnp/<hostname&get;/profiles/peer/
$ cp -p profile.xml profile.xml.bk




/g01/11ggrid/app/11.2.0/grid/gpnp/vmac1/profiles/peer
这个XML文件不能改，


9.7.2.2 关闭所有的crs资源，仅保留crs的后台进程 
crsctl stop crs


--停止相关资源：
[root@rac1 u01]# srvctl stop database -d PROD
[root@rac1 u01]# srvctl stop listener
[root@rac1 u01]# srvctl stop scan_listener
[root@rac1 u01]# srvctl stop scan
[root@rac1 u01]# srvctl stop cvu
[root@rac1 u01]# srvctl stop nodeapps -n vmac1
[root@rac1 u01]# srvctl stop nodeapps -n vmac2


这个ora.cvu 是oracle的一个数据库健康检查进程，他会调用cluster verification utility 工具执行检查工作，然后将日志输出到$GRID_HOME/log/nodename/cvu/cvulog/cvuxxxx.log.
如下：
[grid@rac1 cvulog]$ pwd
/u01/app/grid/11.2.0/log/rac1/cvu/cvulog
[grid@rac1 cvulog]$ ls
cvu20130714124109.log
[grid@rac1 cvulog]$




9.7.2.3 修改public IP地址 
戴明明(251097186)20:57:18
-- 查看当前配置：
[root@rac1 u01]# su - grid
[grid@rac1 ~]$ oifcfg getif -global
[root@vmac1 ~]# oifcfg getif -global
eth1  172.168.9.0  global  cluster_interconnect
eth0  192.168.9.0  global  public
 
戴明明(251097186)20:57:30


----删除public配置
oifcfg delif -global eth0
oifcfg delif -global eth1
PRIF-31: 无法删除指定的网络接口, 因为该接口是最后一个专用接口




----添加public 配置
[grid@rac1 ~]$ 
oifcfg setif -global eth0/192.168.9.0:public
oifcfg setif -global eth1/192.168.8.0:cluster_interconnect


[grid@vmac1 peer]$ oifcfg getif -global
eth1  172.168.9.0  global  cluster_interconnect
eth0  192.168.8.0  global  public
eth1  192.168.8.0  global  cluster_interconnect




9.7.2.4 用grid用户修改VIP 地址 




9.7.2.4.1 查看当前的VIP 信息
[root@rac1 /]# srvctl config nodeapps -a


Network exists: 1/192.168.8.0/255.255.252.0/eth0, type static
VIP exists: /192.168.9.71/192.168.9.72/192.168.8.0/255.255.252.0/eth0, hosting node vmac1
VIP exists: /192.168.9.73/192.168.9.74/192.168.8.0/255.255.252.0/eth0, hosting node vmac2








9.7.2.4.2 用root用户修改VIP 信息


# srvctl modify nodeapps -n <node&get; -A <new_vip_address or new_vip_hostname&get;/<netmask&get;/<[if1[if2...]]&get;


[root@rac1 /]# srvctl modify nodeapps -n vmac1 -A 192.168.9.72/255.255.252.0/eth0
[root@rac1 /]# srvctl modify nodeapps -n vmac2 -A 192.168.9.74/255.255.252.0/eth0
 
[root@vmac1 ~]# srvctl config nodeapps -a
Network exists: 1/192.168.8.0/255.255.252.0/eth0, type static
VIP exists: /192.168.8.71/192.168.8.71/192.168.8.0/255.255.252.0/eth0, hosting node vmac1
VIP exists: /192.168.8.73/192.168.8.73/192.168.8.0/255.255.252.0/eth0, hosting node vmac2




9.7.2.5 修改private IP地址 
D48-俊凯-二期(2394052242)21:02:30
终于起来了 
戴明明(251097186)21:02:32
----删除Private配置
[grid@rac1 ~]$ oifcfg delif -global eth1
PRIF-31: Failed to delete the specified network interface because it is the last private interface
[grid@rac1 ~]$
 
--确认网卡配置：
[root@rac1 /]# oifcfg getif -global
eth1  172.168.9.0  global  cluster_interconnect
eth0  192.168.8.0  global  public
eth1  192.168.8.0  global  cluster_interconnect


9.7.2.5.1 确认网卡配置
[grid@rac1 ~]$ oifcfg getif -global
eth0  192.168.3.0  global  public
eth1  192.168.1.0  global  cluster_interconnect


9.7.2.5.2 用grid用户添加一个新的private 配置
[grid@rac1 ~]$ oifcfg setif -global eth1/192.168.2.0:cluster_interconnect


这里的网卡名称若相同，则网段必须不同。 


--验证：
[grid@rac1 ~]$ oifcfg getif -global
eth1  192.168.1.0  global  cluster_interconnect
eth0  192.168.3.0  global  public
eth1  192.168.2.0  global  cluster_interconnect




9.7.2.6 修改RAC SCAN IP 




--查看scan状态：
[root@rac1 ~]# srvctl config scan
SCAN name: vmac-cluster-scan, Network: 1/192.168.8.0/255.255.252.0/eth0
SCAN VIP name: scan1, IP: /vmac-cluster-scan/192.168.9.89


--准备修改：
$srvctl stop scan_listener
$srvctl stop scan
$srvctl status scan
 
[root@vmac1 ~]# srvctl status scan
SCAN VIP scan1 is enabled
SCAN VIP scan1 is not running




--根据我们/etc/hosts中的修改：
192.168.8.79 rac-scan
 




--用root进行修改：
[root@rac1 ~]# srvctl modify scan -n vmac-cluster-scan


[root@vmac1 ~]# srvctl config scan
SCAN name: vmac-cluster-scan, Network: 1/192.168.8.0/255.255.252.0/eth0
SCAN VIP name: scan1, IP: /vmac-cluster-scan/192.168.8.79


9.7.2.7 用root停止所有节点上的clusterware并禁止其自启动
[root@rac1 u01]# crsctl stop crs  (有些停不掉呀，)
[root@rac1 u01]# crsctl disable crs
