To determine if the node is the primary database node or the application node, run the cluster primary command (with additional parameters) from the CLI on a node:

Note

This command should be used to establish and confirm the primary application node during patch, patch bundle, or delta bundle installation.

platform@VOSS-UN-1:~$ cluster primary
is_primary: true
platform@VOSS-UN-1:~$ cluster primary role application
is_primary: true
platform@VOSS-UN-1:~$ cluster primary role database
is_primary: false
platform@VOSS-UN-1:~$
