当一个事务回滚到某个保存点时，在保存点之后打开的所有未被占用的指针将被关闭。
When a transaction rolls back to a savepoint, all non-hold cursors opened after that savepoint are closed.
在这个结构中提出的另一个方法是协议的性能，当卫星没有在两个未被占用的频率集的交集中没有频率时。
Another proposed approach in this architecture is the behavior of this protocol when no frequency was found by the satellite in the intersection of the two free frequency sets.
由于负载测试通常需要较多的计算资源，在这些资源未被占用时运行测试(例如深夜或清早)会比较好。
Because load testing usually requires an elevated level of computing resources, running tests when these resources are not at capacity - such as late at night or early morning - can be beneficial.
