    • Embodiments of the present invention provide for a method, system and article of manufacture for operating vending machines. In general, a plurality of vending machines are nodes of a network. Each node is configured to send, receive and process signals carrying inventory, pricing, reservation and/or refund information. In particular, a first signal is sent to one or more nodes requesting inventory/price information from other nodes. Those nodes carrying the product may reply with a second signal. In this manner, the location of vending machines carrying one or more items specified by a customer may be determined. In another embodiment, vending machine items may be reserved from a remote location. In still another embodiment, vending machines may be configured to provide refunds under controlled conditions. A consumer may request a refund in cases where the consumer was improperly charged for goods are services that were not provided.
    • 本发明的实施例提供了用于操作自动售货机的方法,系统和制品。 通常,多台自动售货机是网络的节点。 每个节点配置为发送,接收和处理携带库存,定价,预留和/或退款信息的信号。 特别地,第一信号被发送到一个或多个请求来自其他节点的库存/价格信息的节点。 携带产品的那些节点可以用第二个信号进行回复。 以这种方式,可以确定携带客户指定的一个或多个物品的自动售货机的位置。 在另一个实施例中,可以从远程位置预约自动售货机物品。 在另一个实施例中,自动售货机可以被配置为在受控条件下提供退款。 如果消费者不正当地收取货物,消费者可能会要求退款是未提供的服务。

    • A database system has a contention monitor which determines when the level of contention for accessing or inserting records in the database rises above a threshold, and inhibits non-critical access to the database to reduce the level of contention. In a preferred embodiment, the level of contention is determined by periodically measuring the time for an INSERT operation on the database, and comparing the time to a threshold derived from a baseline time measurement for the operation during a time of normal database activity. Thus the contention level is inferred from the time to do the operation, in this case the INSERT query. In one embodiment, the contention monitor notifies a system administrator to take action to reduce the contention. In another embodiment, the contention monitor informs the system to take action automatically according to predetermined selections by the system administrator.
    • 数据库系统具有竞争监视器,其确定何时访问或插入数据库中的记录的竞争级别高于阈值,并且禁止对数据库的非关键访问以降低竞争级别。 在优选实施例中,通过周期性地测量数据库上的INSERT操作的时间,并将时间与从正常数据库活动期间的操作的基线时间测量得出的阈值进行比较来确定争用级别。 因此,从执行操作的时间推断争用级别,在这种情况下是INSERT查询。 在一个实施例中,争用监视器通知系统管理员采取行动以减少争用。 在另一个实施例中,争用监控器通知系统根据系统管理员的预定选择自动采取行动。
