基于不同网段的RAC架构VIP修改

--确认集群当前状态
# crsctl check crs
# crs_stat -t

--关闭集群当前服务
# srvctl stop database -d raw
# srvctl stop asm -n s1-11g
# srvctl stop asm -n s2-11g
# srvctl stop nodeapps -n s1-11g
# srvctl stop nodeapps -n s2-11g

--查看当前配置：
[grid@s1-11g oracle]# oifcfg getif -global
eth0  192.168.72.0  global  public
eth1  10.0.0.0  global  cluster_interconnect

--删除当前配置
[grid@s1-11g oracle]# oifcfg delif -global eth0
[grid@s1-11g oracle]# oifcfg delif -global eth1
[grid@s1-11g oracle]# oifcfg getif

--重新添加
[grid@s1-11g oracle]# oifcfg setif -global eth0/192.168.200.0:public
[grid@s1-11g oracle]# oifcfg setif -global eth1/11.11.11.0:cluster_interconnect
[grid@s1-11g oracle]# oifcfg getif
eth0  192.168.200.0  global  public
eth1  11.0.0.0  global  cluster_interconnect
 
[grid@s1-11g oracle]# oifcfg iflist
eth0  192.168.200.0
eth1  11.0.0.0

--启动集群当前服务
# srvctl start database -d raw
# srvctl start asm -n s1-11g
# srvctl start asm -n s2-11g
# srvctl start nodeapps -n s1-11g
# srvctl start nodeapps -n s2-11g

--关闭相关集群服务
[grid@s1-11g ~]$ srvctl stop scan
[grid@s1-11g ~]$ srvctl stop scan_listener
[grid@s1-11g ~]$ srvctl stop vip -i s1-11g-vip
[grid@s1-11g ~]$ srvctl stop vip -i s2-11g-vip
[grid@s1-11g ~]$ srvctl stop listener

--在两节点/etc/hosts下修改scan IP
#vi /etc/hosts
#192.168.200.90         scan
#192.168.200.93         s1-11g-vip
#192.168.200.94         s2-11g-vip
192.168.200.70          scan
192.168.200.73          s1-11g-vip
192.168.200.74          s2-11g-vip

[grid@s1-11g ~]$ which srvctl
/oracle/grid/crs_1/bin/srvctl
[grid@s1-11g ~]$ exit
logout
[root@s1-11g ~]# /oracle/grid/crs_1/bin/srvctl modify scan -n scan
[root@s1-11g ~]# /oracle/grid/crs_1/bin/srvctl modify nodeapps -n s1-11g -A 192.168.200.73/255.255.255.0/eth0
[root@s1-11g ~]# /oracle/grid/crs_1/bin/srvctl modify nodeapps -n s2-11g -A 192.168.200.74/255.255.255.0/eth0

[grid@s1-11g ~]$ srvctl start scan
[grid@s1-11g ~]$ srvctl start vip -i s1-11g
[grid@s1-11g ~]$ srvctl start vip -i s2-11g
[grid@s1-11g ~]$ srvctl start listener
[grid@s1-11g ~]$ srvctl start scan_listener

--手动设置local_listener参数
alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.200.73)(PORT=1521))' scope=both sid='hzmc1';
alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.200.74)(PORT=1521))' scope=both sid='hzmc2';

--手动设置remote_listener参数
alter system set remote_listener='(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.200.70)(PORT=1521)))' scope=both sid='*';
