When 3rd node is added into a cluster, which files/DB tables will get updated?

Products

• CA API Gateway

Issue/Introduction

We have a cluster which has a primary node and secondary node. When a 3rd node is added into this cluster, which won't copy any primary or secondary DBs, what files/DB tables will be updated?

Environment

API Gateway 10.X

Resolution

When adding a 3rd node (processing node), the cluster_info table will be updated in the database. None of the configuration files (like node.properties and system.properties) will be updated on the primary/secondary.
