Oracle Clusterware consists of two separate technology stacks: an upper technology stack anchored by the Cluster Ready Services (CRS) daemon (CRSD) and a lower technology stack anchored by the Oracle High Availability Services daemon (OHASD). The Clusterware components vary slightly based on the platform.

You can use the installer, gridSetup.sh or the Oracle Fleet Patching and Provisioning (Oracle FPP) utility rhpctl to add a new node to an existing cluster. For more information, see Adding a Cluster Node on Linux and UNIX Systems.
