Oracle Database Appliance provides client interface through ODACLI commands for easy configuration and management of Oracle Data Guard for high availability, data protection, and disaster recovery. Oracle Data Guard Broker is a distributed management framework that automates the creation, maintenance, and monitoring of Oracle Data Guard configurations.

An Oracle Data Guard configuration set up with ODACLI commands consists of one primary database and one standby database. The primary system is the Oracle Database Appliance system that hosts the primary database. The standby system is the Oracle Database Appliance system that hosts the standby database.

Each system runs its own ODACLI which can call operations on the DCS agent. The primary DCS CLI can call operations on primary and standby DCS agent for the odacli configure-dataguard command. It orchestrates a sequence of jobs on two hosts to complete Oracle Data Guard configuration on Oracle Database Appliance. The DCS agent connects with Oracle Data Guard Broker and databases to manage Oracle Data Guard configuration on Oracle Database Appliance.
