About Installing Oracle RAC on Different Operating Systems

If you plan to install and configure Oracle RAC on an operating system other than Oracle Enterprise Linux, you can still use this guide to obtain a general understanding about how to deploy Oracle RAC. You can also use this guide for deploying Oracle RAC on clusters with more than two nodes. For all environments that do not match the environment that this guide describes, modify the examples accordingly.

When installing Oracle RAC on a different platform or different operating system version than Oracle Enterprise Linux or Red Hat Enterprise Linux, refer to the installation and configuration guides for that platform. For example, if you are installing Oracle RAC on the Solaris operating system, then you would use the following guides:

• Oracle Grid Infrastructure Installation Guide for Solaris Operating System

• Oracle Real Application Clusters Installation Guide for Solaris Operating System

Oracle Clusterware and Oracle RAC do not support heterogeneous platforms in the same cluster. For example, you cannot have one node in the cluster running Oracle Enterprise Linux and another node in the same cluster running Solaris UNIX. All nodes must run the same operating system, that is, they must be binary compatible. Oracle RAC does not support machines having different chip architectures in the same cluster. However, you can have machines of different speeds and sizes in the same cluster.
