## Using the p2 for extending your Virgo installation

### Extending with the p2 director

You can provision new features on top of your Virgo installation using the p2 director. It can be used both for initial provisioning and extending an existing installtion.

For extending an existing installation you can use these director arguments:

    -repository http://download.eclipse.org/rt/ecf/3.5.3/site.p2
    -installIU org.eclipse.ecf.remoteservice.feature.feature.group
    -destination <your Virgo installation folder>

This installs the latest version of the specified p2 feature in your Virgo installation's p2 profile.

### Extending via the p2 shell commands

Another way to achieve the same results is to use the p2 commands. The commands are available only in VN as it includes p2 by default.

### Note

For the other distributions only the director is supported and the operation only extends their kernel region.

Here's a list of the most commonly used p2 commands:

`provaddrepo <repository URI>`

Add specified URI as metadata and artifact repository. Note that if you pass a wrong URL you'll get an error saying: `Repository not modifiable: http://wrongURL`. The default behavior of this command is to create an empty repository at the specified location if there isn't any. That won't work for remote locations so keep in mind that if you see this you probably passed a wrong URL.

`provdelrepo <repository URI>` | Remove specified metadata and artifact repository.
`provinstall <InstallableUnit> <version> <profileid>` | Install an IU to the profileid. If no profileid is given, installs into default profile.
`provremove <InstallableUnit> <version> <profileid>` | Uninstall an IU from the profileid. If no profileid is given, uninstalls form default profile.
`provlg [<repository URI> <iu id | *> <version range | *>]` | Lists all IUs with group capabilities in the given repo or in all repos if URI is omitted.
`provliu [<repository URI | *> <iu id | *> <version range | *>]` | Lists the IUs that match the pattern in the given repo. * matches all.
`confapply` | This is a Simple Configurator command, not a p2 one. However it is relevant because it applies dynamically, at runtime, the installed p2 features. What the command does is to apply to the running OSGi framework the current content in the bundles.info file. When using the provinstall command it takes care of updateing the bundles.info file.

Here's an example showing how to install the ECF remote services but with the p2 commands this time:

You can see that after applying the changes with confapply the remote services bundles and their dependencies are installed in VN.
