Adding a node to the cluster

Before adding a node,

Install the operating system software.
create/modify required users and groups.
Configure kernel parameters.
Configure network.
Install the grid and oracle binaries.etc..

check the nodes in the cluster

olsnodes -s -i -t Here we see only 2 nodes in the cluster.

Once the node is ready to add to the cluster,

As grid user,

1. Run the cluster verification utility to confirm the node can be added to the node.

cd $GRID_HOME/bin
./cluvfy stage -pre nodeadd -n RAC3 -fixup -fixupnoexec

2. Run addnode.sh to add the node

cd $GRID_HOME/bin
./addNode.sh -silent "CLUSTER_NEW_NODES={RAC3}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={rac3-vip}"


3. As a root user, execute orainstRoot.sh and root.sh scripts.

4. olsnodes -s -i -t Here the new node is part of the cluster.
