Scheduling a Concurrent program

EBS中的Program是可以根据需求周期性运行的，比如‘Purge Logs and Closed System Alerts’ Program，我们需要每天运行来清理日渐庞大的日志表,周期性运行Program的方法。

路径：Submit Request > Schedule
1.As Soon as Possible:立即运行你的Program

2.Once:在一个具体的时间点上运行Program

3.Periodically:周期的运行你的Program,每分钟/每小时/每天/每周/每月，并制定开始时间和结束时间。

4.On Specific Days:在特定的那几天运行

然后你在Request列表里就能看到你的Scheduled Program。Status为Scheduled,Phase:Pending

或者你用下边脚本，也能看到你的Scheduled Program
