This example has three Job Chains.

Each job chain having its own set of jobs as shown below.

Job_Chain1

  • Job11
  • Job12
  • Job13
  • finish

Job_Chain2

  • Job21
  • Job22
  • Job23
  • finish

Job_Chain3

  • Job31
  • Job32
  • Job33

When Job_Chain1 has finished on host1 Job_Chain2 on host2 should start. When Job_Chain2 on host2 has finished Job_Chain3 on host1 should start.

How it works:

  1. The finish job in Job_Chain1 creates an event for the event processor on host1.
  2. The event handler creates an order for Job_Chain2 on host 2 when the event "jobchain1" arrives. Than the event will "jobchain1" be deleted
  3. The finish job in Job_Chain2 creates an event for the event processor on host1.
  4. The event handler creates an order for Job_Chain3 on host 1 when the event "jobchain2" arrives. Than the event "jobchain2" will be deleted

The event handler

<?xml version="1.0" encoding="UTF-8"?>
<actions>
  <action name="jobchain1">
    <events>
      <event_group group="group">
        <event event_id="jobchain1" event_class="example" />
      </event_group>
    </events>
    <commands>
      <remove_event>
        <event event_id="jobchain1" event_class="example" />
      </remove_event>
      <command name="start_jobchain2" scheduler_host="vmubuntu1" scheduler_port="4444">
        <order job_chain="events_remote/job_chain2" replace="yes" />
      </command>
    </commands>
  </action>
  <action name="jobchain2">
    <events>
      <event_group group="group">
        <event event_id="jobchain2" event_class="example" />
      </event_group>
    </events>
    <commands>
      <command name="command_1">
        <order job_chain="events_remote/job_chain3" replace="yes" />
      </command>
      <remove_event>
        <event event_id="jobchain2" event_class="example" />
      </remove_event>
      <command name="command_2" />
    </commands>
  </action>
</actions>


You can download the source for this example from here.

In the zip, you find two live folders, one for host1 and one for host2.
There is also a event handler for host1. Please copy this the config/events and configure the actual host names or ip addresses.
