摘要： Multiple application server instances can be arranged in a cluster that implements a distributed EJB timer system. A high availability database can store EJB timer info. The EJB timer jobs can be distributed among the application server instances of the cluster that implement the distributed EJB timer system. In case of a failure of an application server instance, the EJB timer info can be used to reassign the EJB timer jobs associated with the failed application server instance.

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。

摘要： The efficiency and versatility for the implementation of formulas in an on-demand database is improved. Formulas are categorized. Based at least partly on the categorization, formulas are evaluated synchronously or asynchronously. An asynchronous evaluation may be performed if a certain set of criteria is not satisfied. Asynchronous evaluations may be performed using a queue. During an asynchronous update of an object, a counter field and/or an estimate field may be used respectively for indicating the consistency of values of the object and a time when the values were consistent. The versatility of formulas is enhanced by using a formula to create a default value for a custom field when it is created and to determine whether an action is to be performed, and is enhanced by having an action define when a formula is to be updated.

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： The efficiency and versatility for the implementation of formulas in an on-demand database is improved. Workflow field formulas are triggered by actions in a workflow, to produce values in fields. Resulting values are protected by preventing a subsequent reevaluation of the workflow field formula from taking place when values of input fields used in the workflow field formula change.

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.

摘要： A system for managing objects in a clustered network includes a file system containing at least one copy of a data object. The system can include several clustered servers in communication with the file system. A distributed consensus algorithm is used to select a host server. The selected host server can contain a copy of the data object, such as in local cache, providing access to the local copy to any other server in the cluster. Any change made to an item hosted by the host server can also be updated in the file system. If the host server becomes unable to host the object, a new host can be chosen using the distributed consensus algorithm. The other servers are then notified of the new host by multicast messaging.
