If ...
- Change only VIP - use "srvctl" to help by root user on each of node
# srvctl modify nodeapps
Example: srvctl modify nodeapps -n DB01 -A 6.9.17.227/255.255.255.240/bond0
1. stop instance, asm , nodeapps
2. check by - srvctl config nodeapps -n node_name -a
3. su - root
4. use srvctl to change VIP
5. check by - srvctl config nodeapps -n node_name -a
6. start nodeapps, asm,instance
7. do on other node from step 1
*** vip must on the same subnet with public IP
-Change IP Public + VIP
1. Stop Oracle Database, ASM , listener and Nodeapps on every nodes (stop
all, if you change to new subnet... if you change,but still in old subnet...
you can do each of node)
2. Change hostname /etc/hosts on every nodes
3. Change IP Address on every nodes
4. Login to root user and export ORACLE_HOME And Change IP Network on
Cluster and VIP
#oifcfg getif
#oifcfg delif ...
#oifcfg setif ...
- Change VIPs on nodes
#srvctl modify nodeapps ...
