Using the System Console is described in the Using Console Commands section.

Managing Features

DDF includes many components, packaged as features, that can be installed and/or uninstalled without restarting the system. Features are collections of OSGi bundles, configuration data, and/or other features. For more information on the features that come with DDF, including a list of the ones included, consult the DDF Included Features page in the Software Version Description Document (SVDD).

Transitive Dependencies

Features may have dependencies on other features and will auto-install them as needed.

Installing Features

Determine which feature to install by looking at the available features on DDF.

ddf@local>features:list

The console should output a list of all features available (installed and uninstalled). A snippet of the list output is shown below (the versions may differ based on the version of DDFbeing run):

State         Version          Name                          Repository  Description
[installed  ] [2.0.1         ] ddf-core                      ddf-2.1.0
[uninstalled] [2.0.1         ] ddf-sts                       ddf-2.1.0
[installed  ] [2.0.1         ] ddf-security-common           ddf-2.1.0
[installed  ] [2.0.1         ] ddf-resource-impl             ddf-2.1.0
[uninstalled] [2.0.1         ] ddf-source-dummy              ddf-2.1.0

Install the desired feature.

ddf@local>features:install ddf-source-dummy

Check the feature list to verify the feature was installed.

ddf@local>features:list

State         Version          Name                          Repository  Description
[installed  ] [2.0.1         ] ddf-core                      ddf-2.1.0
[uninstalled] [2.0.1         ] ddf-sts                       ddf-2.1.0

[installed  ] [2.0.1         ] ddf-source-dummy              ddf-2.1.0

Check the bundle status to verify the service is started.
```
ddf@local>list
```
The console output should show an entry similar to the following:
```
[ 117] [Active     ] [            ] [Started] [   75] DDF :: Catalog :: Source :: Dummy (<version>)
```
