RAC 增加 SCAN

刚开始ip有点紧张，我就只设置了一个SCAN,怕轮询不了，必须在加SCAN IP

这样来增加： [root@esm1 ~]# /u01/grid/11g/bin/srvctl config scan SCAN name: racscan, Network: 1/192.168.116.0/255.255.255.0/eth0 SCAN VIP name: scan1, IP: /racscan/192.168.116.254

我们看看scan监听的情况 [root@esm1 ~]# /u01/grid/11g/bin/srvctl config scan_listener SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521 [root@esm1 ~]# /u01/grid/11g/bin/srvctl status scan_listener SCAN

Listener LISTENER_SCAN1 is enabled SCAN listener

LISTENER_SCAN1 is running on node esm1

停止scan的监听

[root@esm1 ~]# /u01/grid/11g/bin/srvctl stop scan_listener

[root@esm1 ~]# /u01/grid/11g/bin/srvctl status scan_listener SCAN

Listener LISTENER_SCAN1 is enabled SCAN listener LISTENER_SCAN1 is not running

停止scan

[root@esm1 ~]# /u01/grid/11g/bin/srvctl stop scan

增加hosts文件的scan Ip

192.168.116.254 racscan

192.168.116.253 racscan

执行一下修改动作：

[root@esm1 ~]# /u01/grid/11g/bin/srvctl modify scan -n racscan 启动scan 启动监听

[root@esm1 ~]# /u01/grid/11g/bin/srvctl status scan

[root@esm1 ~]# /u01/grid/11g/bin/srvctl status scan_listener
