192.168.2.72 db2
192.168.2.76 db3
#priv ip
200.100.100.11 db1-priv
200.100.100.12 db2-priv

192.168.2.74 db2-vip
192.168.2.77 db3-vip
#scan ip
192.168.2.75 db-scan

192.168.1.71 db1
192.168.1.72 db2
192.168.1.76 db3
#priv ip

192.168.1.75 db-scan
1、查看ocr的備份
[root@db1 bin]# ./ocrconfig -showbackup
2、備份OCR
[root@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、關(guān)閉數(shù)據(jù)庫(kù)
srvctl stop database -d db
4、在任意節(jié)點(diǎn)上修改:
這里我是在節(jié)點(diǎn)1上面操作的
[root@db1 ~]# cd /u01/app/11.2.0/grid/bin/
[root@db1 bin]# ./oifcfg getif
eth0 192.168.2.0 global public
eth2 200.100.100.0 global cluster_interconnect
[root@db1 bin]# ./oifcfg delif -global eth0
[root@db1 bin]# ./oifcfg setif -global eth0/192.168.1.0:public
[root@db1 bin]# ./oifcfg getif
eth2 200.100.100.0 global cluster_interconnect
eth0 192.168.1.0 global public
[root@db1 bin]# ./oifcfg delif -global eth2
PRIF-31: Failed to delete the specified network interface because it is the last private interface
這里不允許刪除最后一個(gè)私有接口,可以先添加一個(gè)私有接口再來(lái)刪除
[root@db1 bin]# ./oifcfg setif -global eth2/200.100.100.0:cluster_interconnect
[root@db1 bin]# ./oifcfg getif
eth2 100.100.100.0 global cluster_interconnect
eth0 192.168.2.0 global public
eth2 200.100.100.0 global cluster_interconnect
[root@db1 bin]# ./oifcfg delif -global eth2/100.100.100.0:cluster_interconnect
[root@db1 bin]# ./oifcfg getif
eth0 192.168.2.0 global public
eth2 200.100.100.0 global cluster_interconnect
在某節(jié)點(diǎn)停止oracle高可能用性服務(wù)
[root@db1 bin]# ./crsctl stop cluster -all
5、修改IP地址及/etc/hosts文件并測(cè)試
6、在所有節(jié)點(diǎn)重新啟動(dòng)所有服務(wù)
[root@db1 bin]#./crsctl start cluster -all
7、停止scan_listener和scan
[root@db1 bin]#./srvctl stop scan_listener
[root@db1 bin]#./srvctl stop scan
8、刪除scan_listener和scan
[root@db1 bin]#./srvctl remove scan_listener -f
[root@db1 bin]#./srvctl remove scan -f
9、添加scan和scan_listener
[root@db1 bin]#./srvctl add scan -n db-scan -k 2 -S 192.168.1.0/255.255.255.0/eth0
說(shuō)明:上面命令中-k 為1(network number)會(huì)報(bào)錯(cuò),因?yàn)橹耙呀?jīng)被使用過(guò)
[root@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
[root@db1 bin]#./srvctl add scan_listener
10、啟動(dòng)scan和scan_listener
[root@db1 bin]#./srvctl start scan
[root@db1 bin]#./srvctl start scan_listener
11、停止VIP資源
[root@db1 bin]# ./crsctl stop resource ora.db1.vip -f
[root@db1 bin]# ./crsctl stop resource ora.db2.vip -f
[root@db1 bin]# ./crsctl stop resource ora.db3.vip -f
這里可以通過(guò)下面命令查看vip的狀態(tài)
[root@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
[root@db1 bin]# ./srvctl modify nodeapps -A 192.168.1.73/255.255.255.0/eth0 -n db1
[root@db1 bin]# ./srvctl modify nodeapps -A 192.168.1.74/255.255.255.0/eth0 -n db2
[root@db1 bin]# ./srvctl modify nodeapps -A 192.168.1.77/255.255.255.0/eth0 -n db3
13、啟動(dòng)VIP資源:
[root@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
[root@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
[root@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
啟動(dòng)VIP資源后本地監(jiān)聽(tīng)就已經(jīng)啟動(dòng)了,下面第14步操作可以不執(zhí)行
14、啟動(dòng)本地監(jiān)聽(tīng):
[root@db1 bin]# ./srvctl start listener -n db1
[root@db1 bin]# ./srvctl start listener -n db2
[root@db1 bin]# ./srvctl start listener -n db3
問(wèn)題:操作完成之后執(zhí)行oifcfg getif,出現(xiàn)在下面的提示信息
[grid@db1 peer]$ oifcfg getif
eth0 192.168.1.0 global public
eth2 100.100.100.0 global cluster_interconnect
Only in OCR: eth2: 100.100.100.0 global cluster_interconnect
PRIF-30: Network information in OCR and GPnP profile differs
說(shuō)網(wǎng)絡(luò)信息在OCR與GPnP不一致,這里重新配置一下即可
[grid@db1 peer]$ oifcfg setif -global eth2/100.100.100.0:cluster_interconnect
[grid@db1 peer]$ oifcfg getif
eth0 192.168.1.0 global public
eth2 100.100.100.0 global cluster_interconnect
