Previous:<\/strong>\u00a0Add additional virtual Ethernet card and perform prerequisites in Linux<\/a><\/p>\n

In order to copy\/clone the VM for node 1 to another VM, first you need to cleanly shutdown the first host i.e. dbhost1<\/p>\n

Once it is cleanly shutdown, you can either user VMWare’s clone option or simply copy the whole VM directory including .vmdk and .vmx files to another directory and name it node2.<\/p>\n

Since this is identical copy if the first node, we don’t want to create IP conflict while starting the VM so this time start only VM for node2 using VMWare or VirtualBox.<\/p>\n

\"\"<\/p>\n

When it prompts following, select “I moved it<\/strong>“. This will preserve all settings including IP address from node 1 VM. Otherwise it will copy the interfaces to ethx.bak and create new interfaces in Linux which we want to avoid.<\/p>\n

Now node2 OS is booted, login with root user.<\/p>\n

In order to change the IP address and hostname, follow these steps.<\/p>\n

Make sure the \/etc\/hosts entries are correct.<\/p>\n

[root@ dbhost2~]#\u00a0more \/etc\/hosts<\/strong><\/p>\n

# Do not remove the following line, or various programs<\/p>\n

# that require network functionality will fail.<\/p>\n

127.0.0.1 localhost.localdomain localhost<\/p>\n

#::1 localhost6.localdomain6 localhost6<\/p>\n

192.168.1.121 dbhost1.paramlabs.com dbhost1<\/strong><\/p>\n

192.168.1.122 dbhost2.paramlabs.com dbhost2<\/strong><\/p>\n

192.168.1.123 dbhost1-vip.paramlabs.com dbhost1-vip<\/strong><\/p>\n

192.168.1.124 dbhost2-vip.paramlabs.com dbhost2-vip<\/strong><\/p>\n

192.168.2.121 dbhost1-priv.paramlabs.com dbhost1-priv<\/strong><\/p>\n

192.168.2.122 dbhost2-priv.paramlabs.com dbhost2-priv<\/strong><\/p>\n

192.168.1.125 dbhost-scan.paramlabs.com dbhost-scan<\/strong><\/p>\n

192.168.1.121 nfshost.paramlabs.com nfshost<\/strong><\/p>\n

Now open the network setup screen as follows.<\/p>\n

\"\"<\/p>\n

It will show 2 existing interfaces with IPs of node 1.<\/p>\n

\"\"<\/p>\n

We need to change IPs for\u00a0eth0<\/strong>\u00a0to match\u00a0dbhost2\u00a0<\/strong>IP. While for\u00a0eth1<\/strong>\u00a0it should match\u00a0dbhost2-priv\u00a0<\/strong>IP. Select the interface and click Edit to make the changes.<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Change the hostname using DNS tab in the network configuration screen. Enter hostname as dbhost2.paramlabs.com<\/strong><\/p>\n

Once you change the IP addresses, make sure to save the configuration using\u00a0File -> Save<\/strong>.<\/p>\n

Once this is done, restart the network service using following command.<\/p>\n

[root@ dbhost2~]#\u00a0service network restart<\/strong><\/p>\n

Change the hostname to\u00a0dbhost2<\/strong><\/p>\n

[root@r12host ~]#\u00a0hostname dbhost2.paramlabs.com<\/strong><\/p>\n

Make sure changes are persistent by restarting network service.<\/p>\n

[root@dbhost2 ~]# service network restart<\/strong><\/p>\n

Shutting down interface eth0: [ OK ]<\/p>\n

Shutting down interface eth1: [ OK ]<\/p>\n

Shutting down loopback interface: [ OK ]<\/p>\n

Bringing up loopback interface: [ OK ]<\/p>\n

Bringing up interface eth0: [ OK ]<\/p>\n

Bringing up interface eth1: [ OK ]<\/p>\n

 <\/p>\n

[root@dbhost2 ~]# ping dbhost2.paramlabs.com -c1<\/strong><\/p>\n

PING dbhost2.paramlabs.com (192.168.1.122) 56(84) bytes of data.<\/p>\n

64 bytes from dbhost2.paramlabs.com (192.168.1.122): icmp_seq=1 ttl=64 time=0.021 ms<\/p>\n

— dbhost2.paramlabs.com ping statistics —<\/p>\n

1 packets transmitted, 1 received, 0% packet loss, time 0ms<\/p>\n

rtt min\/avg\/max\/mdev = 0.021\/0.021\/0.021\/0.000 ms<\/p>\n

Now you can restart Node 2 to make sure the new IPs and new hostname are preserved.\u00a0Also we can start Node 1 now since there will be no conflict now.<\/p>\n

This concludes the steps for creating second node for the RAC.<\/p>\n
