You configure the amount of time a transaction waits before timing out with the derby.locks.waitTimeout property. When configuring your database or system, you should consider these properties together. For example, in order for any deadlock checking to occur, the derby.locks.deadlockTimeout property must be set to a value lower than the derby.locks.waitTimeout property.
