any help would be appreciated!
I was using TB CE V2.3.1 and created approx. 40 devices. TB was running and showing telemetry data for all the devices.
TB was storing data in memory. It worked for a day and then got crashed after giving following error.
error : "Could not open JPA EntityManager for transaction; nested exception is
org.hibernate.exception.JDBCConnectionException: Unable to acquire JDBC Connection"
Any ideas why it would have got crashed?
Now moving to PostgressSQL. But what is the possibility of having same problem with PostgresSQL?
Is there any constraint on using Postgres or data processing?
Why TB recommends Postgres, any specific reason?
What if we configure any other sql DB?
guys, what is the difference between mqtt and mqtt RPC ?
I cant find a good explanation here
Hi there!, just new to the project. I'm currently pushing data through MQTT to a device in the demo thingsboard and the telemetry is just registering the last value, even though i'm sending hundreds of them. Is this a limitation of the demo page? or am i doing something wrong? TY
how you did it my friend?
