DBus service names are postfixed with an instance identifier, so multiple instances can run on the same DBus. Also all relevant configuration files/direcories are either postfixed or put in a separate directory, to avoid any clashes, making it safe to run multiple instances in parallel. The behavior of a normal akonadi instance is not changed. To run multiple akonadi instances in parallel it is required to assign to each instance a unique identifier using: akonadictl --identifier IDENTIFIER start You can run a normal akonadi instance (without --identifier) in parallel with multi-instance akonadi instances. Each instance will run it's own mysql server. Directories The multi-instance setup puts it's files in the following directories: .config/akonadi/instance/$IDENTIFIER .local/share/akonadi/instance/$IDENTIFIER .kde4/share/config/akonadi/akonadi_imap_resource_0_$IDENTIFIERrc To cleanup an instance, just delete all the directories and configs above. Akonadiconsole To connect to an instance using akonadiconsole export the following environment variable first (with inst1 being the instance identifier): export AKONADI_INSTANCE=inst1 A couple of features, such as the debugging facilities or the mysql console do not work, but managing agents and browsing the collection tree should work just fine. Note that you might get an error message on startup that your mysql database socket couldn't be found, this is safe to ignore. You can connect to the mysql instance directly using the mysql console (standalone, not the akonadiconsole one): mysql --protocol=SOCKET --socket=.local/share/akonadi/instance/inst1/socket-myhost2/mysql.socket Missing Features Debugging facilities as mentioned above Firstrun: This must be disabled by exporting AKONADI_DISABLE_AGENT_AUTOSTART, otherwise the firstrun code will crash (an assert prevents running the code since it is unsafe so far). Development In order to make akonadi code work in the multi-instance setup all unique identifiers need to be made distinguishable between instances. That includes most prominently: dbus service names configfile names default directory paths You only need to change these, if you add/use dbus interfaces, or access configfiles directly. Most things have already been taken care of using the agentbase/resourcebase classes. kdepimlibs/akonad/servermanager.h contains a couple of helper functions to help with that.
