How the node.id is created in node.poperties and what are the requirements?

Products

• CA API Gateway

Issue/Introduction

How is the node.id in the node.properties created? Is it related to the host.id in the host.properties?  

Environment

All Supported versions of API Gateway.

Resolution

The node.id is not related to host.id in the host.properties file.  The node.id was randomly generated as an UUID.  The node.id must unique within the gateway cluster.   It can be manually modified from node.properties file, as long as it's unique and meets the cluster requirement.

After the node.id has been changed, the gateway needs to be restarted to make the change effective.
