Change Cluster Interconnect & IP Address in 11gR2 RAC

Change Cluster Interconnect Adapter  & IP Address in 11gR2 RAC We can change it at any stage, it require full outage. Step 1: Determine private IP address [oracle@Jayesh1 ~]$ oifcfg getif eth0  192.168.1.0  global  public eth1  10.0.0.0  global  cluster_interconnect Step 2: Determine Ethernet card name [oracle@Jayesh1 ~]$ oifcfg iflist eth0  192.168.1.0 eth1  10.0.0.0 Step 3: Add new interface Subnet ID specification: [oracle@Jayesh1 ~]$ oifcfg setif -global eth1/175.16.0.0:cluster_interconnect Step 4 : Verify the changes: [oracle@Jayesh1 ~]$ oifcfg getif eth0  192.168.1.0  global  public eth1  10.0.0.0  global  cluster_interconnect eth1  175.16.0.0  global  cluster_interconnect Step 5: Stop cluster on all node: [oracle@Jayesh1 ~]# sudo /u01/app/11.2.0/grid/bin/crsctl stop cluster -all Step 6: Modify netwrok address on network adapter of each box: [root@Jayesh1 ~]# ifconfig eth1 175.16.0.10 n...
