This article is about how ORACLE 11G RAC modifies IP. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Original IP:

# Public IP

192.168.42.201 rac1

192.168.42.202 rac2

# Private IP

20.20.20.201 rac1-priv

20.20.20.202 rac2-priv

# Virtual IP

192.168.42.203 rac1-vip

192.168.42.204 rac2-vip

# Scan IP

192.168.42.205 rac-scan

Modified IP:

# Public IP

192.168.43.101 rac1

192.168.43.102 rac2

# Private IP

10.10.10.101 rac1-priv

10.10.10.102 rac2-priv

# Virtual IP

192.168.43.103 rac1-vip

192.168.43.104 rac2-vip

# Scan IP

192.168.43.105 rac-scan

one。 Modify Public IP

1. View cluster IP information (grid)

Oifcfg getif

two。 Delete the original public IP (grid)

Oifcfg delif-global eth0/192.168.42.0

3. Add a new public IP (grid)

Oifcfg setif-global eth0/192.168.43.0:public

4. View cluster IP information (grid)

Oifcfg getif

5. Modify hosts file (root)

Vi / etc/hosts

# Public IP

192.168.43.101 rac1

192.168.43.102 rac2

two。 Modify Virtual IP

1. Stop Node 1 instance (grid)

Srvctl stop instance-d rac-n rac1

two。 Stop Node 1VIP (grid)

Srvctl stop vip-n rac1-f

3. View vip configuration (grid)

Srvctl config nodeapps-a

4. Modify hosts file (root)

Vi / etc/hosts

# Virtual IP

192.168.43.103 rac1-vip

192.168.43.104 rac2-vip

5. Modify vip configuration (root)

/ u01/app/11.2.0.4/grid/bin/srvctl modify nodeapps-n rac1-A 192.168.43.103/255.255.255.0/eth0

6. Start (grid)

Srvctl start vip-n rac1

Srvctl start listener-n rac1

Srvctl start instance-d rac-n rac1

three。 Modify Scan IP

1. Stop the scan service (grid)

Srvctl stop scan_listener

Srvctl stop scan

two。 Modify hosts file (root)

Vi / etc/hosts

# Scan IP

192.168.43.105 rac-scan

3. Modify scan configuration (root)

Srvctl modify scan-n scanip

4. Modify scan listener configuration (grid)

Srvctl modify scan_listener-u

5. Start the service (grid)

Srvctl start scan_listener

6. Confirm whether it is valid (grid)

Srvctl config scan

four。 Modify Private IP

1. Backup profile.xml

Cd $ORACLE_HOME/gpnp/rac1/profiles/peer/

Cp profile.xml profile.xml.bak

two。 View cluster IP information (grid)

Oifcfg getif

3. Add a new private ip (grid)

Oifcfg setif-global eth2/10.10.10.0:cluster_interconnect

4. View cluster IP information (grid)

Oifcfg getif

5. Shut down and disable clustering for all nodes (root)

/ u01/app/11.2.0.4/grid/bin/crsctl stop crs

/ u01/app/11.2.0.4/grid/bin/crsctl disable crs

6. Modify hosts file (root)

Vi / etc/hosts

# Private IP

10.10.10.101 rac1-priv

10.10.10.102 rac2-priv

7. Open and start the cluster of all nodes (root)

/ u01/app/11.2.0.4/grid/bin/crsctl enable crs

/ u01/app/11.2.0.4/grid/bin/crsctl start crs

8. Delete the original private ip (grid)

Oifcfg delif-global eth2/20.20.20.0

9. View cluster IP information (grid)

Oifcfg getif
