Adding a new node to an existing cluster

The prime objective of this scenario is to describe and demonstrate the tools and methods to add a new node to an existing cluster environment to verticality scale up the environment. Although there are various methods that exist to add a new node, we consider the procedure using the addNode.sh shell script to perform this task among other methods. Just before we initiate the procedure, we assume that there is an existing cluster environment to which a new node, raclinux2, will be added on non-shared Oracle homes.

Note

Please note that until pre 11g R2, we maintained a separate Oracle home for ASM and RDBMS binaries.

Before adding a new node to an existing cluster, the following prerequisites must be met:

• You should have successfully installed Oracle Clusterware on at least one of the nodes in an existing cluster environment.

• All existing nodes in the cluster must be up and running. For any reason, if a node is having problems, you must solve the problems...
