摘要： Concurrency can be maintained in cluster caching when processing an update request on network server that is storing a local copy of a data item. The request can be processed using the local copy of the data item. A predicated update request can be sent to a network database storing the data item, wherein the database can commit the update if the local copy is current with the data item. If the local copy is not current, the network server can request a new copy, process the request using the current copy, and try another predicated request. The process can continue until the update is committed to the database or aborted. Once committed, any other servers in the cluster can be notified that the data item has been updated. Those other servers can drop any local copy of the data item and can request an updated copy of the data item.

摘要翻译：在存储数据项的本地副本的网络服务器上处理更新请求时，可以在群集缓存中维护并发性。可以使用数据项的本地副本处理请求。可以将预测的更新请求发送到存储数据项的网络数据库，其中如果本地副本与数据项目当前一起，则数据库可以提交更新。如果本地副本不是当前副本，则网络服务器可以请求新的副本，使用当前副本处理请求，并尝试另一个预定请求。该过程可以继续，直到更新提交到数据库或中止。一旦提交，群集中的任何其他服务器都可以通知数据项目已被更新。那些其他服务器可以删除数据项的任何本地副本，并可以请求数据项的更新副本。

摘要： Transactions are granted concurrent access to a data item through the use of an optimistic concurrency algorithm. Each transaction gets its own instance of the data item, such as in a cache or in an entity bean, such that it is not necessary to lock the data. The instances can come from the data or from other instances. When a transaction updates the data item, the optimistic concurrency algorithm ensures that the other instances are notified that the data item has been changed and that it is necessary to read a new instance, from the database or from an updated instance.This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

摘要翻译：通过使用乐观并发算法，允许事务同时访问数据项。每个事务获取其自己的数据项实例，例如缓存或实体bean，这样就不需要锁定数据。这些实例可以来自数据或其他实例。当事务更新数据项时，乐观并发算法确保通知其他实例数据项已被更改，并且需要从数据库或更新的实例读取新的实例。

摘要： Servers in a network cluster can each store a copy of a data item in local cache, providing read access to these copies through read-only entity beans. The original data item in the database can be updated through a read/write entity bean one of the cluster servers. That cluster server has access to an invalidation target, which contains identification information relating to copies of the data item stored on servers in the cluster. Once the read/write bean updates the data item in the database, an invalidate request can be sent or multicast to all cluster members, or to any read-only bean or server contained in the invalidation target. Each server or read-only bean receiving the request knows to drop any copy of the data item in local cache, and can request a current copy of the data item from the database.
摘要翻译：网络集群中的服务器可以将每个数据项的副本存储在本地缓存中，通过只读实体bean提供对这些副本的读取访问。可以通过其中一个集群服务器上的读/写实体bean更新数据库中的原始数据项。该集群服务器可以访问无效目标，其中包含与集群中服务器上存储的数据项的副本有关的标识信息。读/写bean更新数据库中的数据项后，可以向所有集群成员或无效目标中包含的任何只读bean或服务器发送无效请求或多播。接收请求的每个服务器或只读bean知道删除本地缓存中的数据项的任何副本，并且可以从数据库请求数据项的当前副本。
