Problem

• If a MySQL DBMS is being used then the MySQL wait_timeout setting that rules the max. lifetime of idle connections should be checked and adjusted if required.
  • The default wait_timeout for MySQL is relatively short and the JOC Cockpit does not keep the connection busy over longer periods without user interaction - for example, overnight. 
  • See the JOC Cockpit - Troubleshooting - Database Connection to MySQL unavailable after idle timeout article for instructions about how to change the MySQL DBMS wait_timeout setting.
