Configuring TCP keepalives for your JDBC connection

By default, the Amazon Redshift JDBC driver is configured to use TCP keepalives to prevent connections from timing out. You can specify when the driver starts sending keepalive packets or turn off the feature by setting the relevant properties in the connection URL. For more information about the syntax of the connection URL, see Building the connection URL.

Property	Description
TCPKeepAlive	To turn off TCP keepalives, set this property to FALSE.
