Oracle 11gR2 RAC修改SCAN IP

Oracle 11gR2 RAC修改SCAN IP地址

192.168.80.24–>192.168.80.25

修改步骤如下：

查看scan_listener状态

[oracle@vastdata1 ~]$ srvctl status scan_listener

SCAN Listener LISTENER_SCAN1 is enabled

SCAN listener LISTENER_SCAN1 is running on node vastdata2

SCAN Listener LISTENER_SCAN2 is enabled

SCAN listener LISTENER_SCAN2 is running on node vastdata2

SCAN Listener LISTENER_SCAN3 is enabled

SCAN listener LISTENER_SCAN3 is running on node vastdata2

查看scan_listener配置

[oracle@vastdata1 ~]$ srvctl config scan_listener

SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521

SCAN Listener LISTENER_SCAN2 exists. Port: TCP:1521

SCAN Listener LISTENER_SCAN3 exists. Port: TCP:1521

查看scan状态

[oracle@vastdata1 ~]$ srvctl status scan

SCAN VIP scan1 is enabled

SCAN VIP scan1 is running on node vastdata2

SCAN VIP scan2 is enabled

SCAN VIP scan2 is running on node vastdata2

SCAN VIP scan3 is enabled

SCAN VIP scan3 is running on node vastdata2

查看scan配置

[oracle@vastdata1 ~]$ srvctl config scan

SCAN name: vastdata-scan.us.oracle.com, Network: 1/192.168.80.0/255.255.255.0/eth0

SCAN VIP name: scan1, IP: /vastdata-scan.us.oracle.com/192.168.80.24

SCAN VIP name: scan2, IP: /vastdata-scan.us.oracle.com/192.168.80.22

SCAN VIP name: scan3, IP: /vastdata-scan.us.oracle.com/192.168.80.23

停止scan_listener

[oracle@vastdata1 ~]$ srvctl stop scan_listener

停止scan

[oracle@vastdata1 ~]$ srvctl stop scan

确认停止后的状态

[oracle@vastdata1 ~]$ srvctl status scan_listener

SCAN Listener LISTENER_SCAN1 is enabled

SCAN listener LISTENER_SCAN1 is not running

SCAN Listener LISTENER_SCAN2 is enabled

SCAN listener LISTENER_SCAN2 is not running

SCAN Listener LISTENER_SCAN3 is enabled

SCAN listener LISTENER_SCAN3 is not running

确认停止后的状态

[oracle@vastdata1 ~]$ srvctl status scan

SCAN VIP scan1 is enabled

SCAN VIP scan1 is not running

SCAN VIP scan2 is enabled

SCAN VIP scan2 is not running

SCAN VIP scan3 is enabled

SCAN VIP scan3 is not running

修改和scan IP相关的文件

[root@vastdata1 ~]# vi /var/named/192.168.80.local

[root@vastdata1 ~]# vi /var/named/us.oracle.com.zone

重启服务

[root@vastdata1 ~]# service named restart

Stopping named: . [ OK ]

Starting named: [ OK ]

修改scan IP

[root@vastdata1 ~]# /u01/app/11.2.0/grid/bin/srvctl modify scan -n vastdata-scan.us.oracle.com

查看是否修改成功

[root@vastdata1 ~]# /u01/app/11.2.0/grid/bin/srvctl config scan

SCAN name: vastdata-scan.us.oracle.com, Network: 1/192.168.80.0/255.255.255.0/eth0

SCAN VIP name: scan1, IP: /vastdata-scan.us.oracle.com/192.168.80.22

SCAN VIP name: scan2, IP: /vastdata-scan.us.oracle.com/192.168.80.23

SCAN VIP name: scan3, IP: /vastdata-scan.us.oracle.com/192.168.80.25

确认修改成功后启动scan_listener

[oracle@vastdata1 ~]$ srvctl start scan_listener

查看启动后scan_listener的状态

[oracle@vastdata1 ~]$ srvctl status scan_listener

SCAN Listener LISTENER_SCAN1 is enabled

SCAN listener LISTENER_SCAN1 is running on node vastdata1

SCAN Listener LISTENER_SCAN2 is enabled

SCAN listener LISTENER_SCAN2 is running on node vastdata2

SCAN Listener LISTENER_SCAN3 is enabled

SCAN listener LISTENER_SCAN3 is running on node vastdata1

查看启动后scan的状态

[oracle@vastdata1 ~]$ srvctl status scan

SCAN VIP scan1 is enabled

SCAN VIP scan1 is running on node vastdata1

SCAN VIP scan2 is enabled

SCAN VIP scan2 is running on node vastdata2

SCAN VIP scan3 is enabled

SCAN VIP scan3 is running on node vastdata1

查看scan修改后的配置

[oracle@vastdata1 ~]$ srvctl config scan

SCAN name: vastdata-scan.us.oracle.com, Network: 1/192.168.80.0/255.255.255.0/eth0

SCAN VIP name: scan1, IP: /vastdata-scan.us.oracle.com/192.168.80.22

SCAN VIP name: scan2, IP: /vastdata-scan.us.oracle.com/192.168.80.23
