c. Add the interface
% $ORA_CRS_HOME/bin/oifcfg setif –global eth0/10.2.166.0:public
d. The same step could be use for the private interface
% $ORA_CRS_HOME/bin/oifcfg delif –global eth1
% $ORA_CRS_HOME/bin/oifcfg setif –global eth1/192.168.1.0:cluster_interconnect
四、修改vip
(note: Stop database instances,stop the ASM instance ,stop the nodeapps )
a. Verifying Current VIP configuration
