db4o Persistence
Documentation of the db4o Persistence Service
db4o is a pure Java object database, which uses a simple database file for persistence.
This persistence service supports writing information to the database as well as querying from it. It keeps all data that you ask it to persist, so the database is growing over time. Please take this into account when defining the items and the strategies for persistence with this service.
As it can happen that the (single) database file is corrupted if the runtime is shutdown ungracefully, this persistence service offers an automatic backup management, so that you can revert at least to an earlier version in case of data corruption.
Additionally, a commit interval can be configured for the database, so that you can optimize the write access to the file system.
For installation of this persistence package please follow the same steps as if you would install a binding.
Additionally, place a persistence file called db4o.persist in the ${openhab.home}/configuration/persistence folder.
This persistence service can be configured in the "Db4o Persistence Service" section in openhab.cfg.
You can choose the backup interval, the number of backups to keep and the commit interval.
All item and event related configuration is done in the db4o.persist file. Aliases do not have any special meaning for the db4o persistence service.
ℹ Please find all documentation for openHAB 2 under http://docs.openhab.org.
The wiki pages here contain (outdated) documentation for the older openHAB 1.x version. Please be aware that a lot of core details changed with openHAB 2.0 and this wiki as well as all tutorials found for openHAB 1.x might be misleading. Check http://docs.openhab.org for more details and consult the community forum for all remaining questions.
