Used to specify the maximum time during which an opened connection can be used by connection pool.
property ConnectionLifetime: integer default DefValConnectionLifetime;
Use the ConnectionLifeTime property to specify the maximum time during which an opened connection can be used by connection pool. Measured in milliseconds. Pool deletes connections with exceeded connection lifetime when TCustomDAConnection is about to close. If the ConnectionLifetime property is set to 0 (by default), then the lifetime of connection is infinity. ConnectionLifetime concerns only inactive connections in the pool.
