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, [[Special:myLanguage/KAddressBook|KAddressBook]] became the first application to start using the '''Akonadi''' framework. In SC 4.7,
<div class="mw-translate-fuzzy">
[[Special:myLanguage/KMail|KMail]], [[Special:myLanguage/KOrganizer|KOrganizer]], [[Special:myLanguage/KJots|KJots]], etc. were updated to use '''Akonadi''' as well. In addition, several [[Special:myLanguage/Plasma|Plasma]] widgets also use '''Akonadi''' to store and retrieve calendar events, notes, etc.
在 KDE 軟體集(KDE Software Compilation)4.4 中,'''通訊錄(KAddressBook)'''成為首個應用'''Akonadi'''的應用程式。在早期的移植階段中不可避免的存在各種小問題,[[Special:myLanguage/Akonadi_4.4/Troubleshooting|疑難排解頁面]]將有助於解決它們。要簡單的了解'''Akonadi'''的用途,可以瀏覽[[Special:myLanguage/Glossary#Akonadi|術語-Akonadi]]。那你也能找到指向進一步閱讀的有用鏈接。一旦這些不可避免的早期問題解決後,'''Akonadi''' 將會通過眾多程式提供源源不斷的可用性。

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.

介紹

在 KDE 軟體集(KDE Software Compilation)4.4 中,通訊錄(KAddressBook)成為首個應用Akonadi的應用程式。在早期的移植階段中不可避免的存在各種小問題,疑難排解頁面將有助於解決它們。要簡單的了解Akonadi的用途,可以瀏覽術語-Akonadi。那你也能找到指向進一步閱讀的有用鏈接。一旦這些不可避免的早期問題解決後,Akonadi 將會通過眾多程式提供源源不斷的可用性。

當前,以下這些程式能使用Akonadi框架集中存儲和訪問用戶數據。點擊了解詳細信息。

KMail

Mail Client

Uses Akonadi to store emails

KAddressBook

Contact Manager

Uses Akonadi to store contact information

KOrganizer

Personal Organizer

Uses Akonadi to store calendars, events, journals, etc.

KJots

Note Taking Application

Uses Akonadi to store notes

In addition to this, plasma widgets like the Digital Clock widget, the Notes widget also use Akonadi to store and retrieve events and notes.

Controlling the Akonadi server

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.

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

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.


Remember

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.


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

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.

Frequently Asked Questions

Where is my data now?

A full explanation of where the data is stored and Akonadi's interaction with it is available in Andras Mantia's blog

How to upgrade my PostgreSQL database?

After updating your PostgreSQL server to a new major version, sometimes you will have to convert your Akonadi database for use with this new version. Instructions can be found on this page.

Migration problems

Akonadi's Glossary entry has a brief description of Akonadi's purpose, and other useful links. This page explains how Akonadi and KAddressBook work together.
