Akonadi

Einführung

Das Akonadi-Framework stellt eine zentrale Datenbank für unterschiedliche Anwendungen bereit, in der persönliche Informationen des Nutzers gespeichert, indiziert und wieder ausgelesen werden können. Das gilt für E-Mails, Kontakte, Kalender, Ereignisse, Tagebücher, Alarme, Notizen usw. Adressbuch war die erste Anwendung, die das Akonadi-Framework genutzt hat. In SC 4.7, kamen KMail, KOrganizer und KJots hinzu. Darüber hinaus nutzen mehrere Plasma- Widgets ebenfalls Akonadi für ihre Kalendereinträge, Notizen, etc.

Zum Zeitpunkt des Schreibens dieses Textes ist bei folgenden Anwendungen Akonadi für die Speicherung ihrer Nutzerdaten vorgesehen. Näheres erfahren Sie auf den Seiten der einzelnen Anwendungen.

KMail
	E-Mail-Programm Verwendet Akonadi zum Speichern von E-Mails
Adressbuch
	Kontakte verwendet Akonadi für Kontaktinformationen
KOrganizer
	Persönlicher Organizer Verwendet Akonadi zum Speichern von Kalenderdaten, Ereignissen, Journalen usw.
KJots

Darüberhinaus verwenden Plasma-Widgets wie Digitaluhr oder Notes ebenfalls Akonadi für ihre Datenhaltung.

Controlling the Akonadi server

The Akonadi control module in System Settings 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.

To start the Akonadi server,

akonadictl start

To stop the Akonadi server,

akonadictl stop

To restart a running Akonadi server,

akonadictl restart

To query the status of the Akonadi server,

akonadictl status

Disabling the Akonadi subsystem

Remember

If you don't want to have Akonadi running on your system, you can not use any of the Akonadi-enabled applications. Such applications will start Akonadi, whenever they need its services even if you have disabled it. See the list of Akonadi-enabled applications. Also note, that some Plasma widgets, such as the Digital Clock uses Akonadi

The Akonadi server is launched automatically at login whenever any Akonadi-enabled application requests access to it.

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

akonadictl stop

Now, edit the file ~/.config/akonadi/akonadiserverrc and change StartServer from true to false:

StartServer=false

The Akonadi server should no longer launch automatically on login.

Note

The Akonadi server will still be started by any Akonadi-enabled application. 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. You must remove any widgets that may start it from your start-up, if you wish Akonadi to remain disabled.

Refer to the Troubleshooting page for resolving glitches during migration. Akonadi's Glossary entry has a brief description of its purpose and other useful links. This page explains how Akonadi and KAddressBook work together.

If you are experiencing 100% CPU usage by the virtuoso-t process when using Akonadi and related applications, try this proposed workaround while it is being investigated: In KRunner's configuration page, disable the Nepomuk search plugin and the Contact plugin. Then, log out and back in. For further information and inputs, report back here or on the Forum or on the IRC channel #kontact.
