OH3.2 without jdbc persistence complains

  • Platform information:
    • Hardware: rpi3 / 1Gb
    • OS: Raspbian
    • Java Runtime Environment: OpenJDK Server VM (build, mixed mode)
    • openHAB version: 3.2

I want to run Openhab with Influxdb persistence. I don’t have any jdbc driver installed, and I don’t have any configuration that installs jdbc-persistence (at least, that is how I intended it to configure).

But in my logging I see (every 5 seconds or so) the next lines, specifying another item every time:

2022-04-15 17:35:40.139 [WARN ] [persistence.jdbc.internal.JdbcMapper] - JDBC::openConnection: no driver available!
2022-04-15 17:35:40.142 [WARN ] [persistence.jdbc.internal.JdbcMapper] - JDBC::openConnection: no driver available!
2022-04-15 17:35:40.149 [WARN ] [jdbc.internal.JdbcPersistenceService] - JDBC::store:  No connection to database. Cannot persist item 'f1_nw_light (Type=NumberItem, State=98.333336, Label=Lichtintensiteit logeerkamer, Category=null, Groups=[gf1_nw, gPersist])'! Will retry connecting to database when error count:0 equals errReconnectThreshold:0

The errors do not appear anymore. Reason unknown.
