Issue/Introduction

Can we use a CNAME in the communication.manageraddress_X field for the scheduler?

Example:
communication.manageraddress_7=<fully qualified hostname>
communication.managerid_7=ACE_SCH
communication.managerport_7=7507
communication.socket_7=plain

Resolution

CNAME, or canonical name (as a hostname) can be used in the agentparm.txt configuration file, specifically for the manager address.

A Canonical Name (CNAME) record is a type of resource record in the Domain Name System (DNS) that maps one domain name (an alias) to another (the canonical name)

Technical Details
Hostname Support: The parameter communication.manageraddress_1 in the agentparm.txt file can be configured using either an IP address or a hostname.
DNS Resolution: If a hostname (including a CNAME) is used, the agent host must be able to resolve that name via DNS to communicate with the scheduler/manager.

Using hostnames instead of static IP addresses in configuration files is generally recommended to ensure that environment changes (such as IP address updates) remain transparent to the application.
