INS-35354
The system on which you are attempting to install Oracle string is not part of a valid cluster.
Cause
Before you can install Oracle %s, you must install Oracle Grid Infrastructure (Oracle Clusterware and Oracle ASM) on all servers to create a cluster.
Action
Oracle Grid Infrastructure for Clusterware 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.
