ORACLE EBS 系统里激活一个职责(Responsibility)

　　激活某个职责，一般来说操作比较简单。
　　1. 用System Administrator职责登录EBS系统。
2. Security => Responsibility => Define => 查找职责，比如 "Workflow Administrator" --> 将"Effective Dates To"列置为空
3. 如果用户反映该职责没有激活，则提交一个"Workflow Background Process" request，将参数"Process Deferred", "Process Timeout" 和 "Process Stuck" 都设为 Yes。
4. 如果用户反映还没有激活，则清理Application Server的Cache，同时建议用户清理IE Cache。
5. 如果用户反映还没有激活，则考虑重启"workflow agent listener"
　　关于"Workflow Background Process" request用途：
Background engine processes serve three purposes in Oracle Workflow: to handle activities deferred by the Workflow Engine, to handle timed out notification activities, and to handle stuck processes.
When the Workflow Engine initiates and performs a process, it completes all necessary activities before continuing to the next eligible activity. In some cases, an activity can require a large amount of processing resource or time to complete. Oracle Workflow lets you manage the load on the Workflow Engine by setting up supplemental engines to run these costly activities as background tasks. In these cases, the costly activity is deferred by the Workflow Engine and run later by a background engine. The main Workflow Engine can then continue to the next available activity, which may occur on some other parallel branch of the process.
