Add a node to a cluster

To add a node in an Oracle clusterware environment, you can clone a copy images of an Oracle clusterware installation, use Grid Control, or invoke addNode.sh.  In general, you install OS, setup network and storage exactly like the current node.   The summary tasks are:

• Check system and network requirements
• Install the required OS pakages
• Set kernel parameters
• Create groups, users, and required directories
• Setup SSH, enable user equivalency, and install owner's shell limits
• Run cluster verify Utility

Perform post hardware and OS check

cluvfy stage -post hwos -n dba0103

Perform a detailed properties comparision of the current node to the new node

cluvfy comp peer -refnode dba0102 -n dba0103 -orainv orainstall -osdba asmdba -verbose

To add a node:

./addNode.sh -silent "CLUSTER_NEW_NODES=dba0103" "CLUSTER_NEW_VIRTUAL_HOSTNAMES=dba0103-vip"

To check integrity on the cluster

cluvfy stage -post nodeadd -n dba0103 -verbose
