Which type of machine will run an automated deferred sync job?

In a Cisco Unified Contact Center Enterprise (UCCE) deployment, the Administration & Data Server (AW/HDS) is the server type responsible for hosting the configuration (awdb) and historical (hds) databases. An automated deferred synchronization job, which pushes configuration changes from the master database to the central controller (Logger), is a core administrative task. This process is executed by the software running on the AW/HDS server. While this job is logically initiated only on the AW/HDS machine that holds the "Principal" role, the fundamental server type that runs the job is the AW/HDS. The question asks for the "type of machine," for which AW/HDS is the most accurate architectural description.

A. Principal AW machine: This describes the logical role of the machine, not its fundamental type. The machine itself is an AW/HDS server that is currently designated as Principal.

B. AW client machine: This is a user workstation for accessing administrative tools. It does not host the server components or run automated backend jobs like synchronization.

C. Secondary AW machine: This machine is a backup that receives configuration data from the Principal AW. It does not initiate the synchronization job to the central controller.

1. Cisco Unified Contact Center Enterprise Design Guide

Release 12.5(1)

Chapter: Unified CCE Components

Section: Administration & Data Server

Quote/Paraphrase: This section explicitly defines the server as the "Administration & Data Server" and notes it is "also known as the AW/HDS because it is where the AW and the Historical Data Server (HDS) are co-located." It establishes AW/HDS as the fundamental machine type. It also clarifies that in a duplexed system

one is designated "principal" where all configuration is performed. This confirms the job runs on a machine of type AW/HDS that has the principal role.

2. Configuration Guide for Cisco Unified Contact Center Enterprise

Release 12.5(1)

Chapter: Configuration Management

Section: Configuration Data Flow

Quote/Paraphrase: The guide details that configuration changes are made on the Administration & Data Server's database (awdb) and then synchronized to the central controller's database (on the Logger). This synchronization process is a function managed by the AW component

which resides on the AW/HDS server. This reinforces that the AW/HDS is the machine type where such jobs are executed.
