I have an Oracle 18.104.22.168c cluster having following 5 nodes :
- Hub Nodes : host01, host02, host03
- Leaf nodes: host04 and host05
I wanted to install RAC database software on the 3 hub nodes i.e. host01, host02 and host03.
I invoked the OUI as oracle user (Owner of Database Home)
[oracle@host01 database_12_1_0_2]$ ./runInstaller
and chose the option to install RAC database software only on the 3 hub nodes.
