1.9 Adding a Node to a Cluster and Scaling an Oracle RAC Database to the Node

To your two-node cluster, you can add a new node, and extend an Oracle RAC Database to the new node, using Rapid Home Provisioning.

Before You Begin

In this procedure, Oracle Grid Infrastructure 12c release 2 (12.2.0.1) is running on the cluster. Working copy GI_HOME_12202_WCPY is the active Grid home on this cluster.

The Oracle RAC Database home runs on the working copy DB_HOME_12202_WCPY .

Ensure that you have storage, network, and operating system requirements configured for the new node as stated in Oracle Grid Infrastructure Installation Guide.

Procedure

1. From the Rapid Home Provisioning Server, run the following command to add a node to the existing Oracle Grid Infrastructure working copy:

   rhpctl addnode gihome -workingcopy GI_HOME_12202_WCPY -newnodes -root n3:n3-vip -root

   The command extends the cluster by adding node3.
2. Add instances to the administrator-managed Oracle RAC Database on the new node:

   rhpctl addnode database -workingcopy DB_HOME_12202_WCPY -dbname db321 -node n3 -root

   The command extends the database home on the node3 and creates database db321 on this node.
