Hi,
I had many months persistence service by “MySQL Persistence”. Few days ago I found that the persistence service does not worked whole time.
I changed persistence to JDBC MariaDb (I have MariadDB) but it does not work still.

I have OpenHab 2.5.2 with MariaDB on Rpi4.
I have already cleared database but without succes. Items does not created.
I tried cleaned cache. No success.

Can anybody help me pls?

I am getting there errors:

[ERROR] [nal.common.AbstractInvocationHandler] - An error occurred while calling method 'QueryablePersistenceService.query()' on 'org.openhab.core.persistence.internal.QueryablePersistenceServiceDelegate@1813401': java.lang.Integer cannot be cast to java.lang.Long

Did you ever solve this? I have the same error.

I cannot say why this is not working, I just want to maybe give you a pointer, because I recently upgraded my working installation of 2.5.2 to 2.5.3, and my mysql persistence completely broke. No updates at all, and no errors in the log.

Solution for me was to download and (re)install the latest Connector/J from the MySQL web page. For mariadb the appropriate connector can be found here:


Perhaps you need to install this. It supposedly works for mysql too.

@panachoi Where did you put the jar? In /usr/share/openhab2/addons/?
