自定义属性在已经针对流程或活动实例进行设置之后可用，或在流程或活动模板上进行设置的情况下，在所有任务状态下可用。
Custom properties are available after they have been set for the process or activity instance, or in all task states, when they are set on the process or activity template.
跳过包含在范围中的活动实例。
对于处于非活动状态的活动，跳过请求会将当前活动实例标记为跳过。
As in the case of inactive activities, the skip request marks the current activity instance to be skipped.
这种映射能够工作得很好，因为它的确将池大小限制在5 之内，同时又没有将活动实例的数目限制为 5。
The mapping works fine, in that it does limit the pool size to 5, but it doesn't limit that number of active instances to 5.
如果为一个活动设置与业务相关的属性，那么该活动实例就会一直持续下去。
If the business relevant attribute is set for an activity, the activity instance is always persisted.
当导航到达活动实例时，该活动的状态将立即被设置为跳过，并且不会运行其实现。
When navigation reaches the activity instance, the state of the activity is immediately set to skipped, and its implementation is not run.
类垃圾回收在缺省情况下是启用的，它负责删除不再拥有任何活动实例的类。
Class garbage collection is enabled by default, which removes classes when they don't have any live instances remaining.
如果两个事件具有相同的活动模板ID （ATID）和相同的流程实例 ID（PIID），那么这两个事件就属于同一个活动实例。
Two events belong to the same activity instance if they have the same activity template ID (ATID) and the same process instance ID (PIID).
这包括正在执行的实例以及需要人工干预的实例，比如包含处于停止状态的活动的实例。
These instances are currently executing, as well as instances that need manual resolution, such as those containing activities in stopped state.
因此，在典型的工作负载过程中，如果将缓存大小设置为预期的最大活动实例数，则性能是最佳的。
Thus, performance is best if the cache size is set to the maximum number of active instances expected during a typical workload.
麻烦在于，如果您的资源数量有限，则有些活动实例正在进行处理，而有些则正在等待资源被释放。
The trouble is, if you have a limited number of resources, some of the active instances are being worked on, and some are waiting for a resource to free up.
发生错误的活动实例被设置为特殊状态已停止。
The activity instance, at which the fault was raised, is put in a special state stopped.
随着活动流程实例数量的增加，系统的性能会大幅度下降。
As the number of active process instances increased, the system's performance degraded significantly.
登录后，就会得到活动实例的一个列表以及用户统计信息、视频演示及其他资源。
Once you are logged in, you'll get a list of your active instances, plus user statistics, video demos, and other resources.
停止的活动实例带有另外一个属性—停止原因，该属性指示活动停止的阶段。
A stopped activity instance carries an additional attribute a "stop reason, which tells the phase when the activity has been stopped."
它可以锁定队列管理器数据，确保队列管理器中只有一个活动实例。
It holds a lock on the queue manager data to ensure that there is only one active instance of the queue manager.
当一个流程实例迁移了之后，流程实例和正在活动的操作引用新模板版本流程。
When a process instance is migrated, the process instance and the activities that are currently active refer to the new template version of the process.
如果您希望(队列实例不含活动应用程序的队列)放置完成且消息被排队，则可以使用集群工作负载等级属性。
Use the cluster workload rank attribute if you want puts (to queues where no instance of the queue has an active application) to complete and messages to be queued.
activity(name).owner 与具有所提供名称的活动实例的所有者绑定。
wf:activity(name).owner is bound to the owner of the activity instance with the supplied name.
他调出第一个进程实例的活动实例列表，并发现RetrieveCustomerData活动的状态为已停止。
He brings-up the activity instance list of the first process instance and finds out that the activity RetrieveCustomerData is in state stopped.
因此，IBMESBQM在wmbmi1上启动一个活动实例，处理所有请求，而wmbmi2上的实例作为一个备用实例，随时准备在活动实例失败时接管。
Hence, IBMESBQM starts as an active instance on wmbmi1, processing all requests, and as a standby instance on wmbmi2, ready to take over if the active instance fails.
Step1的两个实例是活动的，其他传入令牌必须在该任务前面的队列中等待。
Two instances of Step 1 are active, with the other incoming tokens having to wait in the queue in front of the task.
它指定ejb容器内活动实例列表中的bucket数目。
It specifies the number of buckets in the active instance list within the EJB container.
如果您希望(队列实例不含活动应用程序的队列)放置失败，则可以使用放置属性。
Use the put attribute if you want puts (to queues where no instance of the queue has an active application) to fail.
之后您可以在不同机器上定义并启动此队列管理器的多个实例，包括一个活动实例和一个备用实例。
You can then define and start multiple instances of this queue manager on different machines, with one active instance and one standby instance.
