DriverManager.setLoginTimeout() and DriverManager.getLoginTimeout()

When attempting to connect to a data source which is unreliable, to stop the application from hanging (i.e. waiting for a response from the DriverManager,getConnection(...) method), you can use the login timeout integer. This represents a maximum time in seconds that the data source will wait when attempting to connect to the database.

Description from Oracle Java Docs:

DriverManager.setLoginTimeout ( )  - Sets the maximum time in seconds that this data source will wait while attempting to connect to a database. A value of zero specifies that the timeout is the default system timeout if there is one; otherwise, it specifies that there is no timeout. When a DataSource object is created, the login timeout is initially zero.

DriverManager.getLoginTimeout( )  - Gets the maximum time in seconds that this data source can wait while attempting to connect to a database. A value of zero means that the timeout is the default system timeout if there is one; otherwise, it means that there is no timeout. When a DataSource object is created, the login timeout is initially zero.
