定时任务 meaning in English
timing task
Examples
- These particular files also have an extra field that allows you to stipulate the user account under which the cron job runs
Etc cron . d whatever 。这些特殊的文件可以包含一个额外的域，允许您指定运行该定时任务的用户帐户。 - On the other hand , if you have a cron job that needs to run as a special user , or needs to run at a special time or frequency , you can use either
另一方面，如果您有某个定时任务a需要以某个特定的用户身份运行，或者b需要在某个特定时刻或以特定周期运行，您可以使用 - If the application already performs timed tasks , backups could be added to the existing list ; otherwise , it is important to implement some mechanism that will schedule database backups at regular intervals
如果应用程序已经在执行定时任务，那么可以将备份任务添加到现有列表中，否则应该实现某种机制，以便定期进行数据库备份。 - This paper includes the following aspects : ( 1 ) by comparing of a various of software schemes , the modularization and hierarchical structure is presented ; ( 2 ) the real - time operating system vxworks is used to administrate the resource ; ( 3 ) time - event driven strategy based on message and time processing is chosen to meet the system demands ; ( 4 ) the vertical and horizontal hierarchical structure is applied to design the application layer of aocs ; ( 5 ) the simulation practice of some functions has been finished
通过对软件设计方案的深入分析和比较，本文应用一些实用方法和技术，给出了一种姿轨控系统软件体系结构的设计方案。课题主要研究内容有以下几个方面：通过对设计方案的分析比较，提出了模块化层次结构的设计方法；基于实时操作系统vxworks对资源管理层进行了设计；运行调度层采用基于消息和定时任务处理的混合驱动模式进行了设计；采用纵横结合型层次结构对领域应用层进行了设计；在方案设计的基础上，完成了部分功能的仿真实践。
