Use the detailed instructions in the Oracle Grid Infrastructure Installation Guide to perform the following steps on the source node:
Install Oracle Clusterware 12c. This installation puts Oracle Cluster Registry (OCR) and the voting file on Oracle Automatic Storage Management (Oracle ASM).
Note:
Either install and configure the Oracle Grid Infrastructure for a cluster or install just the Oracle Clusterware software, as described in your platform-specific Oracle Grid Infrastructure Installation Guide.
If you installed and configured Oracle Grid Infrastructure for a cluster, then you must stop Oracle Clusterware before performing the cloning procedures. If you performed a software-only installation, then you do not have to stop Oracle Clusterware.
Install any patches that are required (for example, an Oracle Grid Infrastructure bundle patch), if necessary.
