Shulou Source: shulou.com Published: 2022-05-31 15:17:15 10月03日 Update

Editor to share with you how to modify the ip address of rac, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Oracle release 11.2.0.4.0

This experiment mode netmask:255.255.255.0

1: modify the host ip,vip,scan (the name of the network card remains the same)

Second: modify Private IP

Third, modify the name of the public network card and keep the ip address unchanged.

4: modify the name of the Private Nic and keep the ip address unchanged

5: modify the name of the public network card, ip

6: modify the name of the Private network card, ip

Appendix: subnet Mask address calculation

Backup: 2 hosts:

VPC configuration exists not only in ocr, but also in gpnp profile, so you need to back up profile.xml first:

[grid@host01 peer] $pwd

/ u01/11.2.0/grid/gpnp/host01/profiles/peer

[grid@host01 peer] $ls

Pending.xml profile.old profile_orig.xml profile.xml

[grid@host01 peer] $cp profile.xml profile.xml.bak

[root@host02 ~] #

[root@host02 ~] # cd / u01/11.2.0/grid/gpnp/host02/profiles/peer/

[root@host02 peer] # ls

Profile_orig.xml profile.xml

[root@host02 peer] # cp profile.xml profile.xml.bak

Ocr backup:

[root@host01] # / u01/11.2.0/grid/bin/ocrconfig-manualbackup

Host02 2018-03-29 08:48:19 / u01/11.2.0/grid/cdata/host-cluster/backup_20180329_084819.ocr

[root@host01] # / u01/11.2.0/grid/bin/ocrconfig-showbackup

Backup of hosts configuration files:

* *

Scenario one

* *

Modify the host ip,vip,scan (the name of the Nic remains the same)

Before modification:

# 192.168.0.35 host01

# 192.168.0.36 host01-vip

# 192.168.0.38 host02

# 192.168.0.39 host02-vip

# 192.168.0.40 scan

After modification:

172.16.0.135 host01

172.16.0.136 host01-vip

172.16.0.138 host02

172.16.0.139 host02-vip

172.16.0.140 scan

1. Normal library shutdown, monitoring and CRS

# / u01/11.2.0/grid/bin/crsctl stop crs

two。 Modify / etc/hosts configuration file

172.16.0.135 host01

172.16.0.136 host01-vip

172.16.0.138 host02

172.16.0.139 host02-vip

172.16.0.140 scan

3.OS layer modifies the address of the public network card

4. Start crs

# / u01/11.2.0/grid/bin/crsctl start crs

5. Modify Public IP

[grid@host01 ~] $oifcfg iflist

Eth4 172.16.0.0

Eth5 10.168.0.0

Eth5 169.254.0.0

[grid@host01 ~] $oifcfg getif

Eth4 192.168.0.0 global public

Eth5 10.168.0.0 global cluster_interconnect

[grid@host01 ~] $oifcfg delif-global eth4

[grid@host01 ~] $oifcfg setif-global eth4/172.16.0.0:public

[grid@host01 ~] $oifcfg getif

Eth5 10.168.0.0 global cluster_interconnect

Eth4 172.16.0.0 global public

6. Modify VIP-- to stop database and snooping

Srvctl stop vip-n host01

Srvctl stop vip-n host02

# root user modifies:

Srvctl modify nodeapps-n host01-A 172.16.0.136/255.255.255.0/eth4

Srvctl modify nodeapps-n host02-A 172.16.0.139/255.255.255.0/eth4

[root@host01] # / u01/11.2.0/grid/bin/srvctl config vip-n host01

VIP exists: / 172.16.0.136/172.16.0.136/172.16.0.0/255.255.255.0/eth4, hosting node host01

[root@host01] # / u01/11.2.0/grid/bin/srvctl config vip-n host02

VIP exists: / host02-vip/172.16.0.139/172.16.0.0/255.255.255.0/eth4, hosting node host02

/ u01/11.2.0/grid/bin/srvctl start vip-n host01

/ u01/11.2.0/grid/bin/srvctl start vip-n host02

Confirm local_listener information:

Check the local_listener information. If it is incorrect and needs to be modified, my query here is correct.

-- the two nodes confirm respectively:

Show parameter local_listener

-- modify:

Alter system set local_listener=' (ADDRESS= (PROTOCOL=TCP) (HOST=172.16.0.136) (PORT=1521)) 'sid='orcl1'

Alter system set local_listener=' (ADDRESS= (PROTOCOL=TCP) (HOST=172.16.0.139) (PORT=1521)) 'sid='orcl2'

7. Modify SCAN VIP

Srvctl stop scan_listener

Srvctl stop scan

Srvctl status scan_listener

Srvctl status scan

# root

/ u01/11.2.0/grid/bin/srvctl modify scan-n scan

/ u01/11.2.0/grid/bin/srvctl config scan

SCAN name: scan, Network: 1/172.16.0.0/255.255.255.0/eth4

SCAN VIP name: scan1, IP: / scan/172.16.0.140

/ u01/11.2.0/grid/bin/srvctl start scan

/ u01/11.2.0/grid/bin/srvctl start scan_listener
