Hello Rajendra, For instance if you are using MYSQL a validationQuery="l" in your datasource configuration [1] plus the magic autoreconnect parameter in the URL can do the trick for you. However this can have side effects (see the mysql autoreconnect description).
In my experience the cheapest option use to be to restart your application. Hope it helps, Luis [1] https://commons.apache.org/proper/commons-dbcp/configuration.html [2] https://dev.mysql.com/doc/connector-j/8.0/en/connector-j-reference-configuration-properties.html El lun., 18 mar. 2019 a las 17:24, Rajendra (<rajendrapopur...@gmail.com>) escribió: > Hi, > > Tomcat(8.5.32) is not establishing connections to database after database > is restarted.
