  1. In the VMware console, go to the Virtual Machine menu and choose Add Virtual Machine to Inventory.
  2. Browse to RAC11g/collabn2 and open collabn1.vmx. Make sure you browse to the right folder!

  3. In the Inventory tab at the left, select the new VM – collabn2. Choose the Console tab and click the play button to start the VM.

  4. The VMware console should ask you whether you copied or moved the VM. Answer that you copied the files and click OK.

  5. When you see the square boxes, click anywhere to open a console window.

  6. Login as the oracle user with the password racattack.

  7. Open a terminal ( Applications >> Accessories >> Terminal ) and switch to the root user.

  8. CONFIRM that the IP address of eth1 starts with 172.16.100.

    [root@collabn1 ~]# ifconfig|grep net
    eth1      Link encap:Ethernet  HWaddr 00:0C:29:C9:3E:C8
              inet addr:  Bcast:  Mask:
              inet addr:  Mask:
  9. Update the IP addresses by directly editing the linux network configuration files. Update the BOOTPROTO line and add the remaining lines.

    COMMENT or DELETE the line which begins with HWADDR.

    [root@collabn1 ~]# cd /etc/sysconfig/network-scripts
    [root@collabn1 network-scripts]# gedit ifcfg-eth0
    [root@collabn1 network-scripts]# gedit ifcfg-eth1
  10. Update the DNS search domain

    [root@collabn1 network-scripts]# gedit /etc/resolv.conf
    search vm.ardentperf.com
  11. Update the HOSTNAME by editing the linux system configuration files. Set it to collabn2.vm.ardentperf.com. Then change the active system hostname with the hostname command.

    [root@collabn1 network-scripts]# gedit /etc/sysconfig/network
    [root@collabn1 network-scripts]# hostname collabn2.vm.ardentperf.com
  12. As root, restart the network services by typing service network restart. Then confirm the new ip addresses with ifconfig. Confirm that search domain by inspecting /etc/resolv.conf – if the file has reverted then edit it again. (The change stuck after the second time I edited the file while walking through this lab.) Also confirm the new hostname with hostname.

  13. Exit your terminal session and start a new one so that you can see the updated hostname in the prompt.

  14. Edit /etc/hosts. EDIT the line with and then ADD all of the other lines below:

    [root@collabn2 etc]# vi /etc/hosts   collabn1 collabn1.vm.ardentperf.com   collabn1-vip collabn1-vip.vm.ardentperf.com   collabn1-priv collabn1-priv.vm.ardentperf.com   collabn2 collabn2.vm.ardentperf.com   collabn2-vip collabn2-vip.vm.ardentperf.com   collabn2-priv collabn2-priv.vm.ardentperf.com  collab-scan collab-scan.vm.ardentperf.com  collab-gns collab-gns.vm.ardentperf.com       localhost.localdomain localhost
    ::1             localhost6.localdomain6 localhost6
