| 摘 要： | 针对长事务在较长一段时间占有数据库资料，明显地延迟了短事务和普通事务的执行这一问题，对两步锁进行改进和扩充，给出一种利它锁协议及其操作原理，让长事务按一定的协议较早地释放其占用的锁，使需要存取这些被锁数据的事务在长事务处于唤醒状态时，遵循一定的锁规则同时运行。

| Abstract: | In consideration of database resources occupied for relatively long periods of time by longer transactions, which evidently delays the execution of shorter and common transactions, an expansion and improvement to the two phase locking are carried out An altruistic locking protocol and its operational primitive are proposed The longer transaction releases its occupied locks earlier based on the some protocols to make the transactions accessing the released data existed in waking condition while following the appropriate locking rules in their operations |
