Oracle Database Machine is an integrated data warehousing solution that eases data warehousing by integrating the whole hardware and software stack into one solution. DB Machine management simplifies monitoring and managing the DB Machine by integrating all hardware and software components into one entity. You do not need to monitor each target individually but instead you can view the whole DB Machine as a single target. You can view all critical issues in the system, monitor performance, and drill down to individual targets from the DB Machine target homepage.
Enterprise Manager automatically or manually discovers the components of the DB Machine and adds these components as managed targets. You can modify the member targets of the DB Machine by adding and removing targets.
The DB Machine homepage includes the following components:
The hardware schematic allows you to view hardware components of the DB Machine (for example, compute nodes, Exadata cells, and Infiniband switches), monitor critical hardware metrics and view aggregated alerts and faults from all components.
Alerts sourced from hardware components.
Easily accessible links and flows to other key feature such as viewing the topology or modifying the schematic
You can also monitor all components of the DB Machine. DB Machine monitors all subcomponent targets, whether hardware or software. This includes the database, ASM, CRS, hosts, Exadata and the Infiniband network. The two targets available to facilitate DB Machine monitoring are:
Exadata Storage Server
Infiniband Network Fabric
Note:
The following are the minimum requirements for a DB Machine to be monitored and managed by Enterprise Manager Release 12c:Minimum required Exadata Software version 11.2.2.3 and above
Supported hardware version
Pre-requirement to verify the existence of the Schematic file and the minimum required version. If that does not exist, you must download and run the latest version of Configurator to generate the schematic file.
Required Schematic file generated with the DB Machine Configurator of version 120 and above on the compute node where the Enterprise Manager agent in installed.
