disable persistent connections in mariadb for jdbc:mysql

Question

Is there any way how to disable persistent jdbc:mysql connections to mariadb directly in tomcat/or mariadb server? I would like to do it similar way how I did it for php, where I disabled it in PHP (scripts in PHP won't fail, they'll just use non-persistent connections silently).

I have a java servlet which produces many connections which stay in sleep for very long time and causes "too many connection" issue.

As I am not java programmer, I am not able to change java servlet codes. (so I need to do it at higher level if possible)

Answer 1

• Lower the wait_timeout .

• Decrease the number of connections in your "connection pool", if you have one.

• Decrease the number of "clients" in your web server is willing to spawn.

• As a last resort, increase MySQL/MariaDB's max_connections .
