Maybe this will help: > [@MQTT config under OH2](https://community.openhab.org/t/mqtt-config-under-oh2/15497/9): > > @Rob_Pope I had a similar problem in the past… It was due to OpenHab 2 loading up the default mqtt.cfg config file (with the sample \ name)… it was my mistake since I removed the comments from the lines without adjusting the broker name… After I fixed the mistake, the \ info still remained (as a second broker) in OH2 “internal database” (I don’t know how to call it :)) and was causing errors because all other parameters for \ were null. Try to check with the Karaf Console … Check in karaf if there is any stable config parameters for mysql & jdbc ```auto config:list "(service.pid=org.openhab.mysql)" config:list "(service.pid=org.openhab.jdbc)" ``` If there are wrong stuff there, delete the stored config: ```auto config:delete org.openhab.mysql config:delete org.openhab.jdbc ``` Fix your .config and .persist files and let OH2 re-read them to populate the stored configs. Oops.. I missed that part: > [@DanielMalmgren](#): > > when I look in the config files the url is changed back You mean that your /etc/openhab2/services/mysql.cfg file is being updated by OH2? (this shouldn’t happen…) --- _[View the full topic](https://community.openhab.org/t/solved-persistence-url-keeps-changing/20696)._
