[root@node2~]#srvctlstatusdatabase-dtan

Instancetan1isrunningonnodenode1

Instancetan2isrunningonnodenode2

4.关闭数据及CRS

database-dtan

[root@node1~]#srvctlstatusdatabase-dtan

Instancetan1isnotrunningonnodenode1

Instancetan2isnotrunningonnodenode2

[root@node1~]#srvctlstoplistener-nnode1

[root@node1~]#srvctlstoplistener-nnode2

[root@node1~]#srvctlstopvip-nnode1

[root@node1~]#srvctlstopvip-nnode2

PRCC-1017:node2-vipwasalreadystoppedonnode2

PRCR-1005:Resourceora.node2.vipisalreadystopped

[root@node1~]#srvctlstopscan_listener

[root@node1~]#srvctlstopscan

2个节点都需要停掉CRS

withtheCRSdaemon.

[root@node1~]#crsctlcheckcrs

CRS-4639:CouldnotcontactOracleHighAvailabilityServices

[root@node1~]#crsctlcheckcluster

CRS-4639:CouldnotcontactOracleHighAvailabilityServices

CRS-4000:CommandCheckfailed,orcompletedwitherrors.

[root@node1~]#

[root@node1~]#ps-ef|grepgrid

root1406226218023:46pts/200:00:00grepgrid

5.修改2个节点hosts中的public-ip,vip,scan-ip

暂不修改Priv-ip,修改后如下：

"eth0"

BOOTPROTO="static"

HWADDR="00:0C:29:7D:D1:29"

NM_CONTROLLED="yes"

ONBOOT="yes"

TYPE="Ethernet"

IPADDR=192.168.114.11

NETMASK=255.255.255.0

GATEWAY=192.168.115.254

[root@node2~]#cd/etc/sysconfig/network-scripts/

[root@node2network-scripts]#viifcfg-eth0

DEVICE="eth0"

BOOTPROTO=static

ONBOOT="yes"

TYPE="Ethernet"

IPADDR=192.168.114.12

NETMASK=255.255.255.0

GATEWAY=192.168.114.254

HWADDR="00:50:56:27:B7:1A"

7.集群启动CRS

checkcrs

CRS-4638:OracleHighAvailabilityServicesisonline

CRS-4535:CannotcommunicatewithClusterReadyServices

CRS-4529:ClusterSynchronizationServicesisonline

CRS-4534:CannotcommunicatewithEventManager

等一会再看

checkcrs

CRS-4638:OracleHighAvailabilityServicesisonline

CRS-4537:ClusterReadyServicesisonline

CRS-4529:ClusterSynchronizationServicesisonline

CRS-4533:EventManagerisonline

[root@node1~]#crs_stat-t

NameTypeTargetStateHost

------------------------------------------------------------

ora.CRS.dgora....up.typeONLINEONLINEnode1

ora.DATA.dgora....up.typeONLINEONLINEnode1

ora....ER.lsnrora....er.typeOFFLINEOFFLINE

ora.scan2.vipora....ip.typeOFFLINEOFFLINE

ora.scan3.vipora....ip.typeOFFLINEOFFLINE

ora.tan.dbora....se.typeOFFLINEOFFLINE

8.使用oifcfg修改public-IP

[root@node1 ~]# oifcfg getif

eth0192.168.150.0 global public

eth2172.168.146.0 global cluster_interconnect

[root@node1 ~]#oifcfg delif -global eth0

[root@node1 ~]#oifcfg setif -global eth0/192.168.114.0:public

[root@node1 ~]# oifcfg getif

eth2172.168.146.0 global cluster_interconnect

eth0192.168.114.0 global public

9.使用srvctl修改VIP

[root@node2 ~]# srvctl stop database -d tan-o immediate

PRCC-1016 : tan was already stopped

[root@node2 ~]# srvctl config vip -n node1

VIP exists:/node1-vip/192.168.114.13/192.168.150.0/255.255.255.0/eth0, hosting node node1

[root@node2 ~]# srvctl config vip -n node2

VIP exists:/node2-vip/192.168.114.14/192.168.150.0/255.255.255.0/eth0, hosting node node2

[root@node2 ~]# srvctl stop listener -nnode1

[root@node2 ~]# srvctl stop listener -nnode2

[root@node2 ~]# srvctl stop vip -n node1

[root@node2 ~]# srvctl stop vip -n node2

[root@node2 ~]# srvctlmodify nodeapps -n node1 -A 192.168.114.13/255.255.255.0/eth0

[root@node2 ~]# srvctlmodify nodeapps -n node2 -A 192.168.114.14/255.255.255.0/eth0

[root@node2 ~]# srvctl config vip -n node1

VIP exists:/node1-vip/192.168.114.13/192.168.114.0/255.255.255.0/eth0, hosting node node1

[root@node2 ~]# srvctl config vip -n node2

VIP exists:/node2-vip/192.168.114.14/192.168.114.0/255.255.255.0/eth0, hosting node node2

10. 使用srvctl修改SCANIP

修改SCANIP

[root@node1 ~]# srvctl config scan

SCAN name: scanip, Network:1/192.168.114.0/255.255.255.0/eth0

SCAN VIP name: scan1, IP:/scanip/192.168.150.15

SCAN VIP name: scan2, IP:/scanip/192.168.150.16

SCAN VIP name: scan3, IP:/scanip/192.168.150.17

[root@node1 ~]# srvctl stop scan_listener

[root@node1 ~]# srvctl stop scan

[root@node1 ~]# srvctlmodify scan -n scanip

注：这儿的scanip是/etc/hosts里的名字

192.168.114.15 scanip

192.168.114.16 scanip

192.168.114.17 scanip

检查确认：

[root@node1 ~]# srvctl config scan

SCAN name: scanip, Network:1/192.168.114.0/255.255.255.0/eth0

SCAN VIP name: scan1, IP:/scanip/192.168.114.15

SCAN VIP name: scan2, IP:/scanip/192.168.114.16

SCAN VIP name: scan3, IP:/scanip/192.168.114.17

启动scan

[root@node1 ~]# srvctl start scan

[root@node1 ~]# srvctl start scan_listener

11. 使用oifcfg修改私有PRIV-IP

[root@node1 ~]# oifcfg getif

eth2172.168.146.0 global cluster_interconnect

eth0192.168.114.0 global public

是一个网段，这儿就不用改了，如果需要改，参考修改public-ip

修改2个节点/etc/hosts

172.168.146.11 node1-priv

172.168.146.12 node2-priv

修改2个节点eth2物理地点

"eth2"

BOOTPROTO="static"

HWADDR="00:0C:29:7D:D1:33"

NM_CONTROLLED="yes"

ONBOOT="yes"

TYPE="Ethernet"

IPADDR=172.168.146.11

NETMASK=255.255.255.0

GATEWAY=172.168.150.1

[root@node2network-scripts]#viifcfg-eth2

DEVICE="eth2"

BOOTPROTO="static"

HWADDR="00:50:56:3E:DF:A5"

NM_CONTROLLED="yes"

ONBOOT="yes"

TYPE="Ethernet"

IPADDR=172.168.146.12

NETMASK=255.255.255.0

GATEWAY=172.168.150.1

12. 逐个启动相关进程

[root@node1 ~]# srvctl start vip -n node1

[root@node1 ~]# srvctl start vip -n node2

[root@node1 ~]# srvctl start listener -nnode1

[root@node1 ~]# srvctl start listener -nnode2

[root@node2 ~]# srvctl start database -dtan

[root@node1 ~]# srvctl status database -dtan

Instance tan1 is running on node node1

Instance tan2 is running on node node2

13. 修改参数local_listener

alter system setlocal_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.114.13)(PORT=1524))))'sid='tan1';

alter system setlocal_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.114.14)(PORT=1524))))'sid='tan2';

14. 测试

SQL> conn system/oracle@tanx

已连接。
