oracle 11gR2 修改DNS方式(SCAN IP)

这篇文章介绍11gR2环境下如何修改dns环境下的scan ip
以下例子为将
192.168.3.231,192.168.3.232,192.168.3.233
改为
192.168.3.234,192.168.3.235,192.168.3.236

以下为具体实施过程：
[root@rac1 bin]# nslookup racnode-cluster-scan.racnode.com
Server: 192.168.3.32
Address: 192.168.3.32#53
Name: racnode-cluster-scan.racnode.com
Address: 192.168.3.231
Name: racnode-cluster-scan.racnode.com
Address: 192.168.3.232
Name: racnode-cluster-scan.racnode.com
Address: 192.168.3.233

1.检查目前scan ip环境
[root@rac1 bin]# nslookup racnode-cluster-scan.racnode.com
Server: 192.168.3.32
Address: 192.168.3.32#53
Name: racnode-cluster-scan.racnode.com
Address: 192.168.3.236
Name: racnode-cluster-scan.racnode.com
Address: 192.168.3.235
Name: racnode-cluster-scan.racnode.com
Address: 192.168.3.234

[grid@rac1 trace]$ srvctl config scan
SCAN name: racnode-cluster-scan.racnode.com, Network: 1/192.168.3.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /192.168.3.231/192.168.3.231
SCAN VIP name: scan2, IP: /192.168.3.233/192.168.3.233
SCAN VIP name: scan3, IP: /192.168.3.232/192.168.3.232
[grid@rac1 trace]$
srvctl config scan_listener
[root@rac1 bin]# ./srvctl modify scan -n racnode-cluster-scan.racnode.com
[root@rac1 bin]#
[grid@rac1 trace]$ 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
[grid@rac1 trace]$

2.停止scan ip
[grid@rac1 trace]$ srvctl stop scan_listener
[grid@rac1 trace]$ srvctl stop scan
[grid@rac1 trace]$ crs_stat -t

3.检查scan ip 资源 是否停止
[grid@rac1 trace]$ 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
[grid@rac1 trace]$ 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
[grid@rac1 trace]$

4.root用户进行修改
[root@rac1 bin]# ./srvctl modify scan -n racnode-cluster-scan.racnode.com
[root@rac1 bin]#

5.修改dns服务器上的ip
1.dns 域名ip配置进行修改
2.dhcp ip范围段进行修改

6.确认结果和启动scan ip
[grid@rac1 trace]$ srvctl config scan
SCAN name: racnode-cluster-scan.racnode.com, Network: 1/192.168.3.0/255.255.255.0/eth0

SCAN VIP name: scan3, IP: /racnode-cluster-scan.racnode.com/192.168.3.235
[grid@rac1 trace]$ 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
[grid@rac1 trace]$ srvctl start scan
[grid@rac1 trace]$ srvctl start scan_listener
