ORACLE RAC11G 更改IP地址

wer2122121

环境：oracle 11.2.0.4  rac

修改前IP地址
# public ip
192.168.2.71 db1
192.168.2.72 db2
192.168.2.76 db3
#priv ip
200.100.100.11 db1-priv
200.100.100.12 db2-priv
200.100.100.13 db3-priv
#vip ip
192.168.2.73 db1-vip
192.168.2.74 db2-vip
192.168.2.77 db3-vip
#scan ip
192.168.2.75 db-scan
修改后IP地址
# public ip
192.168.1.71 db1
192.168.1.72 db2
192.168.1.76 db3
#priv ip
100.100.100.11 db1-priv
100.100.100.12 db2-priv
100.100.100.13 db3-priv
#vip ip
192.168.1.73 db1-vip
192.168.1.74 db2-vip
192.168.1.77 db3-vip
#scan ip
192.168.1.75 db-scan



1、查看ocr的备份
[iyunv@db1 bin]# ./ocrconfig -showbackup

2、备份OCR
[iyunv@db1 bin]# ./ocrconfig -manualbackup

db3     2015/01/29 19:58:22     /u01/app/11.2.0/grid/cdata/db-scan/backup_20150129_195822.ocr


3、关闭数据库
srvctl stop database -d db

4、在任意节点上修改：
这里我是在节点1上面操作的
[iyunv@db1 ~]# cd /u01/app/11.2.0/grid/bin/
[iyunv@db1 bin]# ./oifcfg getif
eth0  192.168.2.0  global  public
eth1  200.100.100.0  global  cluster_interconnect

[iyunv@db1 bin]# ./oifcfg delif -global eth0
[iyunv@db1 bin]# ./oifcfg setif -global eth0/192.168.1.0:public
[iyunv@db1 bin]# ./oifcfg getif
eth1  200.100.100.0  global  cluster_interconnect
eth0  192.168.1.0  global  public

[iyunv@db1 bin]# ./oifcfg delif -global eth1
PRIF-31: Failed to delete the specified network interface because it is the last private interface
这里不允许删除最后一个私有接口，可以先添加一个私有接口再来删除
[iyunv@db1 bin]# ./oifcfg setif -global eth1/200.100.100.0:cluster_interconnect
[iyunv@db1 bin]# ./oifcfg getif
eth1  100.100.100.0  global  cluster_interconnect
eth0  192.168.2.0  global  public
eth1  200.100.100.0  global  cluster_interconnect

[iyunv@db1 bin]# ./oifcfg delif -global eth1/100.100.100.0:cluster_interconnect
[iyunv@db1 bin]# ./oifcfg getif
eth0  192.168.2.0  global  public
eth1  200.100.100.0  global  cluster_interconnect
在某节点停止oracle高可能用性服务
[iyunv@db1 bin]# ./crsctl stop cluster -all

5、修改IP地址及/etc/hosts文件并测试

6、在所有节点重新启动所有服务
[iyunv@db1 bin]#./crsctl start cluster -all

7、停止scan_listener和scan
[iyunv@db1 bin]#./srvctl stop scan_listener
[iyunv@db1 bin]#./srvctl stop scan

8、删除scan_listener和scan
[iyunv@db1 bin]#./srvctl remove scan_listener -f
[iyunv@db1 bin]#./srvctl remove scan -f
9、添加scan和scan_listener
[iyunv@db1 bin]#./srvctl add scan -n db-scan -k 2 -S 192.168.1.0/255.255.255.0/eth0
说明:上面命令中-k 为1（network number）会报错，因为之前已经被使用过
[iyunv@db1 bin]# ./srvctl config scan
SCAN name: db-scan, Network: 2/192.168.1.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /db-scan/192.168.1.75

[iyunv@db1 bin]#./srvctl add scan_listener

10、启动scan和scan_listener
[iyunv@db1 bin]#./srvctl start scan
[iyunv@db1 bin]#./srvctl start scan_listener

11、停止VIP资源
[iyunv@db1 bin]# ./crsctl stop resource ora.db1.vip -f
[iyunv@db1 bin]# ./crsctl stop resource ora.db2.vip -f
[iyunv@db1 bin]# ./crsctl stop resource ora.db3.vip -f
这里可以通过下面命令查看vip的状态
[iyunv@db1 bin]# ./crsctl stat res -t
ora.db1.vip
      1        OFFLINE OFFLINE                                                   
ora.db2.vip
      1        OFFLINE OFFLINE                                                   
ora.db3.vip
      1        OFFLINE OFFLINE

12、修改vip地址
[iyunv@db1 bin]# ./srvctl modify nodeapps -A 192.168.1.73/255.255.255.0/eth0 -n db1
[iyunv@db1 bin]# ./srvctl modify nodeapps -A 192.168.1.74/255.255.255.0/eth0 -n db2
[iyunv@db1 bin]# ./srvctl modify nodeapps -A 192.168.1.77/255.255.255.0/eth0 -n db3


13、启动VIP资源：
[iyunv@db1 bin]# ./crsctl start resource ora.db1.vip -f
CRS-2672: Attempting to start 'ora.db1.vip' on 'db1'
CRS-2676: Start of 'ora.db1.vip' on 'db1' succeeded
[iyunv@db1 bin]# ./crsctl start resource ora.db2.vip -f
CRS-2672: Attempting to start 'ora.db2.vip' on 'db2'
CRS-2676: Start of 'ora.db2.vip' on 'db2' succeeded
[iyunv@db1 bin]# ./crsctl start resource ora.db3.vip -f
CRS-2672: Attempting to start 'ora.db3.vip' on 'db3'
CRS-2676: Start of 'ora.db3.vip' on 'db3' succeeded
启动VIP资源后本地监听就已经启动了，下面第14步操作可以不执行

14、启动本地监听：

[iyunv@db1 bin]# ./srvctl start listener -n db1
[iyunv@db1 bin]# ./srvctl start listener -n db2
[iyunv@db1 bin]# ./srvctl start listener -n db3
问题：操作完成之后执行oifcfg getif，出现在下面的提示信息
[grid@db1 peer]$ oifcfg getif
eth0  192.168.1.0  global  public
eth1  100.100.100.0  global  cluster_interconnect
Only in OCR: eth1:  100.100.100.0  global  cluster_interconnect
PRIF-30: Network information in OCR and GPnP profile differs
说网络信息在OCR与GPnP不一致，这里重新配置一下即可
[grid@db1 peer]$ oifcfg setif -global eth1/100.100.100.0:cluster_interconnect
[grid@db1 peer]$ oifcfg getif
eth0  192.168.1.0  global  public
eth1  100.100.100.0  global  cluster_interconnect
