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