Public VIP Address<\/strong>: An interface that can be used for communication with components external to Oracle RAC instances, such as Oracle Net and Virtual Internet Protocol (VIP) addresses.
\nWe can change VIP with any outage. We will change it node by node.<\/p>\n

Step 1: Check which service is running on current which VIP , we want to change<\/strong>
\n[oracle@test1 ~]$ srvctl status service -s <database>
\n[oracle@test1 ~]$ srvctl status service -d orcl
\nService dev is running on instance(s) orcl1
\nService taxi is running on instance(s) orcl1
\nService web is running on instance(s) orcl1<\/p>\n

Step 2: Stop these services<\/strong>
\n[oracle@test1 ~]$ srvctl stop service -d <DB_NAME> -s <Service_name1,Service_name2> -n <hostname><\/p>\n

[oracle@test1 ~]$ srvctl stop service -d orcl -s dev,taxi,web -n test1<\/p>\n

Step 3: Find VIP address:<\/strong>
\n[oracle@test1 ~]$ srvctl config\u00a0 vip -n <host_name>
\n[oracle@test1 ~]$ srvctl config vip -n test1
\nVIP exists: \/test1-vip\/192.168.1.106\/192.168.1.0\/255.255.255.0\/eth0, hosting node test1<\/p>\n

Step 4: Stop VIP of current node<\/strong>
\n[oracle@test1 ~]$ srvctl stop\u00a0 vip -n <host_name>
\n[oracle@test1 ~]$ srvctl stop\u00a0 vip -n test1
\nPRCR-1014 : Failed to stop resource ora.test1.vip
\nPRCR-1065 : Failed to stop resource ora.test1.vip
\nCRS-2529: Unable to act on ‘ora.test1.vip’ because that would require stopping or relocating ‘ora.LISTENER.lsnr’, but the force option was not specified.<\/p>\n

CRS-2529:<\/strong> There is some\u00a0 dependent services on VIP of this node.<\/p>\n

Stop VIP forcefully on this node.<\/p>\n

[oracle@test1 ~]$ srvctl stop\u00a0 vip -n test1 -f<\/em><\/strong><\/p>\n

(-f :: forcefully)<\/p>\n

Step 5: Verify VIP is down:<\/strong><\/p>\n

\ninet addr:127.0.0.1\u00a0 Mask:255.0.0.0<\/p>\n

Step 6: Modify VIP<\/strong>
\n[oracle@test1 ~]$ srvctl modify nodeapps -n test1 -A 192.168.1.115\/255.255.255.0\/eth0<\/p>\n

Step 7: Make changes into \/etc\/hosts file on all nodes and domain name server,<\/strong>
\nNew IP address with their respective host name.<\/p>\n

Step 8: Start VIP<\/strong><\/p>\n

[oracle@test1 ~]$ srvctl start\u00a0 vip -n test1<\/p>\n

Step 8: Verify VIP<\/strong>
\n[oracle@test1 ~]$ \/sbin\/ifconfig -a | egrep ‘(eth0|Mask)’

\ninet addr:127.0.0.1\u00a0 Mask:255.0.0.0<\/p>\n

Step 9: Start dependent services<\/strong>
\n[oracle@test1 ~]$ srvctl start service -d orcl -s dev,taxi,web<\/p>\n

Check services status
\n[oracle@test1 ~]$ srvctl status service -d orcl -s dev,taxi,web
\nService dev is running on instance(s) orcl1
\nService taxi is running on instance(s) orcl1
\nService web is running on instance(s) orcl1<\/p>\n

Step 10: Repeat step-1 to step-9 on the other nodes.<\/strong><\/p>\n

Step 11: Verify Node connectivity between all nodes:<\/strong>
