In-Depth Information
Once you are on the last configuration page for the target, you are presented with a navigation tree on the left side
of the screen and a series of tabs on the right side. These structures enable you to navigate the current configuration
information associated with the target. Each target type will present a different navigation tree; the tab on the right will
stay the same. Figure

shows an example of the latest configuration for an Oracle 11g database.

Lastest configuration for an Oracle database
When looking at the configuration for a database, a DBA can monitor and enforce the configurations of
parameters associated with the initialization file (spfile), OS parameters, and cell configuration within Exadata or any
other database. Configuration enforcement can be done by comparing two hosts that have the same configuration
to identify any issues on one of the hosts. Comparison of configurations can also be done against a target's saved
configuration, considered the gold standard, to determine whether any drift exists within the target's configuration.
■
Comparing target configurations or using a gold image for comparison requires a large amount of data. it is best
to run comparisons during nonpeak hours.
Tip
Oracle Enterprise Manager can also compare the configurations of multiple Exadata Database Machines.
Capabilities such as change history tracking or configuration management inventory help with configuration
compliance as well. Oracle Enterprise Manager continuously captures the change events in the Oracle Exadata and
