RAC Attack - Oracle Cluster Database at Home/Configure Node 1

After completing the previous lab, you should already be logged in as the oracle user on collabn1. You should already have a terminal open, where you are currently switched to the root user. As the root user, CONFIRM that the IP address if eth0 starts with 192.168.78 and that the IP address of eth1 starts with 172.16.100. [root@collabn1 ~]# ifconfig|grep net eth0 Link encap:Ethernet HWaddr 00:0C:29:07:F5:C0 inet addr:192.168.78.128 Bcast:192.168.78.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe07:f5c0/64 Scope:Link eth1 Link encap:Ethernet HWaddr 00:0C:29:07:F5:CA inet addr:172.16.100.128 Bcast:172.16.100.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe07:f5ca/64 Scope:Link inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:HostUpdate the IP addresses by directly editing the linux network configuration files. Update the BOOTPROTO line and add the remaining lines. [root@collabn1 ~]# cd /etc/sysconfig/network-scripts [root@collabn1 network-scripts]# gedit ifcfg-eth0 BOOTPROTO=none IPADDR=192.168.78.51 NETMASK=255.255.255.0 GATEWAY=192.168.78.2 [root@collabn1 network-scripts]# gedit ifcfg-eth1 BOOTPROTO=none IPADDR=172.16.100.51 NETMASK=255.255.255.0Update the DNS search domain [root@collabn1 network-scripts]# gedit /etc/resolv.conf search vm.ardentperf.com nameserver 192.168.78.2As root, restart the network services by typing service network restart. Then confirm the new ip addresses with ifconfig. Also confirm the search domain by inspecting /etc/resolv.conf – if the file has reverted then edit it again. (When I wrote this lab, the change stuck after the second time I edited the file.) You must perform this step in VMware; do not use PuTTY. none|border|550pxEdit /etc/ hosts. EDIT the line with 127.0.0.1 and then ADD all of the other lines below: [root@collabn1 etc]# vi /etc/hosts 192.168.78.51 collabn1 collabn1.vm.ardentperf.com 192.168.78.61 collabn1-vip collabn1-vip.vm.ardentperf.com 172.16.100.51 collabn1-priv collabn1-priv.vm.ardentperf.com 192.168.78.52 collabn2 collabn2.vm.ardentperf.com 192.168.78.62 collabn2-vip collabn2-vip.vm.ardentperf.com 172.16.100.52 collabn2-priv collabn2-priv.vm.ardentperf.com 192.168.78.250 collab-scan collab-scan.vm.ardentperf.com 192.168.78.251 collab-gns collab-gns.vm.ardentperf.com ::1 localhost6.localdomain6 localhost6 127.0.0.1 localhost.localdomain localhost Configure Disks Configure Node 2
