Failed to initialize pool: Database may be already in use: "C:/opt/snaplogic/run/bstore-Emirates_Training-sidekick-dev-1.mv.db"

I have not open the snaplogic designer to make a connection, this issue is coming while doing configuration on groundplex, please refer below steps

I have modified – opt/snaplogic/etc/keys.properties file and /opt/snaplogic/etc/global.properties file after that while executing below commands got the exception.

cd ~/opt/snaplogic/run/lib
$ java -jar jcc.war jcc

For better understand my question, please go to this url Snap Development Documentation and seet the configuration section.

Exception:
