    • *ecflow_start.sh 脚本会自动启动 ecflow_server。手动启动 ecFlow 后，服务器处于 halted 状态，需要 restart 服务器。halted 状态的服务器不会调度任务。

文本方式

检查服务器的状态，输入下列 unix 命令

ecflow_client --stats

运行结果

windroc@ubuntu:~/course$ ecflow_client --stats

如果 ecflow_server 处于 halted 状态，需要重新启动服务器
手动进入 halted 状态

windroc@ubuntu:~/course$ ecflow_client --halt
Are you sure you want to halt the server ? y

重新启动

windroc@ubuntu:~/course$ ecflow_client --restart

一旦 ecflow_server 处于 running 状态，就可以启动 suite

windroc@ubuntu:~/course$ ecflow_client --begin=test

检查状态

Python方式

重新启动和开始调度 suite 可以通过 Client Server API 完成，修改 client.py 并重新运行。
注：如果之前加载过 suite，则注释掉 ci.load(..) 行。

#!/usr/bin/env python2.7
import ecflow
try:
    print "Loading definition in 'test.def' into the server"
    ci = ecflow.Client()
    ci.load("test.def")
    print "Restarting the server. This starts job scheduling"
    ci.restart_server()
    print "Begin the suite named 'test'"
    ci.begin_suite("test")
except RuntimeError as e:
    print "Failed:",    e

测试：

windroc@ubuntu:~/course$ ecflow_client --delete=_all_
Are you sure you want to delete all the suites ? y
windroc@ubuntu:~/course$ ecflow_client --halt
Are you sure you want to halt the server ? y
windroc@ubuntu:~/course$ python client.py
Loading definition in 'test.def' into server
Restarting the server. This starts job scheduling
Begin the suite named 'test'

任务

  1. 重新启动 ecflow_server
  2. 开始调度 suite
