Before you can install Oracle string, you must install Oracle Grid Infrastructure (Oracle Clusterware and Oracle ASM) on all servers to create a cluster.
Oracle Grid Infrastructure is not installed. Install it either from the separate installation media included in your media pack, or install it by downloading it from Electronic Product Delivery (EPD) or the Oracle Technology Network (OTN). Oracle Grid Infrastructure normally is installed by a different operating system user than the one used for Oracle Database. It may need to be installed by your system administrator. See the installation guide for more details.
