oracle 11gR2 修改 DNS 方式 SCAN IP
這篇文章介紹11gR2環境下如何修改dns環境下的scan ip
以下例子為將
192.168.3.231,192.168.3.232,192.168.3.233
改為
192.168.3.234,192.168.3.235,192.168.3.236
以下為具體實施過程：
[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.檢查目前scan ip環境
[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
Name Type Target State Host

3.檢查scan ip 資源 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_SCAN3 is enabled
SCAN listener LISTENER_SCAN3 is not running
[grid@rac1 trace]$
4.root使用者進行修改
[root@rac1 bin]# ./srvctl modify scan -n racnode-cluster-scan.racnode.com
[root@rac1 bin]#
5.修改dns伺服器上的ip
1.dns 域名ip配置進行修改
2.dhcp ip範圍段進行修改
6.確認結果和啟動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: scan1, IP: /racnode-cluster-scan.racnode.com/192.168.3.234

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
