B4J Question What is the best way when my raspberry gets cutt of from power?

[jayel]

Hello,

I have an app on my raspberry pi that communicate with a device on the serial port.
I have setup a jetty webserver with ABMaterial on the raspberry to view settings and see the communication.
I use Poolmanager to get en set data to an mysql database.
My problem :
When I don't close the raspberry pi as it should (sudo poweroff or sudo reboot), so the process can close the pool connection to my database, the next time the program runs I get a error from the poolmanager.
I have looked around the forum and saw the majority of these errors has to do with not closing the poolmanager as it should.
How would you suggest how to handle such a setup?
Work with API? Work with RDC?

Which error do you get?

Where is the database server running? On the Raspberry Pi?

 

[jayel]

java.sql.SQLException: An attempt by a client to checkout a Connection has timed out.

No, the database is running on a server on my LAN.

I don't think that it is related to closing the pool. Maybe the RPi was not connected yet to the network.

I updated the mysql connector and now I don't get the error anymore.
I hope it stays this way.
