Adding a new network to RAC cluster
There are scenarios where it is required to add additional public network to a RAC cluster in order to segregate the network traffic from the default public network. In our case the requirement was to come up with a separate network which is dedicated to carry the backup traffic between the RAC servers and the enterprise backup server. Below are the steps which were followed during the setup on Oracle 11.2 cluster (2 nodes) running on top of Solaris 10. Before the start, make sure the new IPs are assigned in the network level and available on all nodes of the cluster. In our case below are the test IPs assigned. node 1 - IP --> 172.20.60.46 | VIP --> 172.20.60.146 node 2 - IP --> 172.20.60.47 | VIP --> 172.20.60.147 Step 1 - Add new IP entries to host file. ##Backup Network 172.20.60.46 cbbacknode1 172.20.60.47 cbbacknode2 ##Backup VIP 172.20.60.146 vip-cbbacknode1 172.20.60.147 vip-cbbacknode2 Step 2 - Check currently assigned networks...
