activiti.cfg.xml配置文件，你能配置需要的历史归档的级别：

    
     ...
    

可以配置如下的历史级别：

• none: skips all history archiving. This is the most performant for runtime process execution, but no historical information will be available.

  忽略所有的历史归档。尽管对于运行期流程执行来说这是性能最高的，但是没有历史信息保留。

• activity: archives all process instances and activity instances. No details will be archived

  归档所有流程实例和活动实例。不归档细节。

• audit: This is the default. It archives all process instances, activity instances and all form properties that are submitted so that all user interaction through forms is traceable and can be audited.

  这是缺省级别。它归档所有流程实例，活动实例和提交的表单属性。以至于通过表单的所有用户交互都是可跟踪并可以被审计。

• full: This is the highest level of history archiving and hence the slowest. This level stores all information as in the audit level plus all other possible details like process variable updates.

  这是历史归档的最高级别。所以是最慢的。这个水平保存audit级别的所有信息加上像流程变量的所有其它可能的细节。
