Query historical events : write a session bean or servlet to query the historical events by event groups using event access interface 查询历史事件：书写会话bean或servlet ，并利用event access接口，通过事件组查询历史事件。
Event consumers subscribe and listen for events . an administrator can configure event group profiles contained within an event group profile list ，事件消费者预定和监听事件，管理员可以配置包含在事件组概要清单中的事件组概要。
Create event groups : create event groups using websphere administration console and associate them with the appropriate jms destinations , if required 创建事件组：利用websphere administration console创建事件组，如果需要，将事件组与适当的jms目标关联。
It works by exploiting a real - time topological view of the network to analyze the " tree structure " of bgp events , thereby isolating individual sets of events resulting from a common source 事件的“树结构”进行工作，从而隔离由同一来源产生的单个事件组。
If the event distribution service is enabled default and an event matches an event group , it is distributed to the queues configured for the event group 如果事件分布（ event distribution ）服务启动了（默认）并且事件与事件组匹配，那么该事件就将分布到为事件组设定的队列中。
If the cei server receives a cbe and distribution is enabled , it will check to see if the event matches any of the event groups configured in the eventgroupprofilelist 如果cei服务器接收到cbe ，并启用分布，它将会检查该事件是否与eventgroupprofilelist中配置的事件组相匹配。
In this section , we illustrate how to query the historical events using the xpath and how to define the event groups and use them with the event access interface 在本部分，我们将举例说明如何利用xpath查询历史事件以及如何定义事件组及如何通过event access接口来使用事件组。
For a list of the predefined groups of ddl and dml statements that are available for event notifications , the particular statements they cover , and the scope at which these event groups can execute , see 有关可用于事件通知的预定义ddl和dml语句组、它们所包含的特定语句以及可执行这些事件组的作用域的列表，请参阅
Then use these events to get the completion , orders data , and invalid orders data events by using the corresponding event group and qualifying it with the process context , obtained from the process start events 然后，利用这些事件，通过使用相应的事件组并将事件组在流程环境中加以限定，来得到从流程启动事件中获得的完成、定购数据和无效的定购数据事件。
