There are three key tools that you can use to manage the Oracle Database Appliance. Together, these tools are adequate to completely manage, maintain, and operate Oracle Database Appliance including the hardware platform, the operating system, and the databases running on the system.
Oracle Integrated Lights Out Manager (a.k.a., Oracle ILOM)
Oracle ILOM provides a “just like being there” experience and allows you to completely manage your system remotely (including powering it up and shutting it down) over a dedicated network interface. You can start the Remote Console over a web interface to connect to an Oracle Database Appliance server node, check status of hardware components, manage faults (if any), monitor system temperature and ambience, re-image server, and so forth. Point your web browser to the IP address you have configured for the server’s ILOM network interface, and there you are. You typically configure Oracle ILOM interface on Oracle Database Appliance server nodes at the time of initial deployment using the Configurator (when you issue the "oakcli deploy" command). Alternatively, you can configure ILOM before the deployment using the server’s BIOS utility (pressing the F2 key during system boot), or using the “ipmitool” utility from the server operating system command line. You can also configure Oracle ILOM on Oracle Database Appliance after the initial deployment of the system using any of the latter two methods (BIOS or ipmitool).
Oracle Enterprise Manager Database Control (OEM)
Oracle Enterprise Manager Database Control is a no-cost tool to manage Oracle databases and it can be automatically configured at the time of initial deployment of Oracle Database Appliance. Database Control provides a web user interface to manage, maintain, and operate the Oracle database. This includes administering users, data structures, database and instances, user sessions, backup and recovery, analyzing performance, tuning SQL, instance, and database, and so forth. Alternatively, if you use Oracle Enterprise Manager Grid Control or Oracle Enterprise Manager Cloud Control in your organization, you can use it to manage databases running on Oracle Database Appliance. An Oracle Database Appliance plug-in may also become available for Oracle Enterprise Manager Cloud Control in the future.
Oracle Appliance Manager (oakcli)
Oracle Appliance Manager command-line interface (oakcli) provides unique abilities to manage, maintain, and operate the Oracle Database Appliance platform. This includes setup and deployment of the system, running diagnostics on servers and storage, patching server, storage, and network, and creating multiple Oracle homes and database environments, and so forth. Starting with Oracle Appliance Manager 2.8, you can also monitor the hardware (servers, CPUs, power, cooling, and so forth) using oakcli. You can invoke Oracle Appliance Manager command-line interface using the /opt/oracle/oak/bin/oakcli command from an Oracle Database Appliance server node.
