It normally uses a preferred path for I/ O; DMMP will switch to a standby path if the preferred path meets with failure. 它通常使用I/O偏好路径;如果偏好路径遇到问题,DMMP将切换到独立路径。
If any element of an I/ O path ( the cable, switch, or controller) fails, DMMP switches I/ O to an alternate path. 如果I/O路径的任何元素(电缆、交换机或控制器)失败,DMMP将把I/O切换到备用路径。
In this case, the event subprocess is interruptible ( denoted by the solid line around the message icon below)& we don't want the main process path to continue, but instead for control to switch to the activities inside the event subprocess. 在这种情况下,事件子流程是不可中断的(由下面的消息图表周围的实线表示)&我们不希望继续执行主要流程路径,而是希望将控制权转移给该事件子流程内的活动。
You will need to either add it to the path or switch to the directory where it is installed before running it from the command line. 在从命令行运行它之前,必须将其添加到该路径上或切换到安装它的目录。
