The Akonadi framework is responsible for providing applications with a centralized database to store, index and retrieve the user's personal information. This includes the user's emails, contacts, calendars, events, journals, alarms, notes, etc. In SC 4.4, KAddressBook became the first application to start using the Akonadi framework. In SC 4.7, KMail, KOrganizer, KJots, etc. were updated to use Akonadi as well. In addition, several Plasma widgets also use Akonadi to store and retrieve calendar events, notes, etc.

En el momento de escribir esto, las siguientes aplicaciones están configuradas para usar la infraestructura Akonadi para almacenar y acceder a los datos del usuario de forma centralizada. Visita la página de cada aplicación para aprender más.

Control del servidor Akonadi

The Akonadi control module started by the context menu of the Akonadi tray icon provides an easy means to starting, stopping, restarting and querying the status of the Akonadi server. You may also accomplish this from the commandline using the command akonadictl. Using this method, you can get additional useful information on the console.

Para iniciar el servidor Akonadi,

akonadictl start

Para detener el servidor Akonadi,

akonadictl stop

Para reiniciar un servidor Akonadi en ejecución,

akonadictl restart

Para comprobar el estado del servidor Akonadi,

akonadictl status

Disabling the Akonadi subsystem

The Akonadi server is started by any Akonadi-enabled application. If you don't want Akonadi to be started after login, you have to ensure that no Akonadi-enabled application is launched at login or thereafter. Remember to check Plasma widgets as well — the Digital Clock widget in the default panel, for instance uses Akonadi to (optionally) display calendar events and this is enabled in its settings by default (see the "Display Events" option) . You must remove any widgets that may start it from your start-up, if you wish Akonadi to start only when you start KMail or other applications.

If you don't want to have Akonadi running on your system at all, you can not use any of the Akonadi-enabled applications. Such applications will not work when Akonadi is disabled using the steps below. See the list of Akonadi-enabled applications. Also note, that some Plasma widgets, such as the Digital Clock uses Akonadi.

El servidor Akonadi se ejecuta automáticamente al iniciar sesión cada vez que alguna aplicación necesita acceder a él.

To disable the Akonadi subsystem, shut down the running Akonadi server from the control module or the command line:

akonadictl stop

To ensure that Akonadi is not started, check that no applications require it at login. In particular, open the Plasma clock applet preferences, go to Calendar and uncheck Show events to prevent Plasma from requesting information from Akonadi and thus allowing it to start.
