Starting a job chain from a running job chain
1. create a job CallJobchain
<job order="yes"
stop_on_error="no"
enabled="yes"
>
<settings>
<log_level><![CDATA[debug9]]></log_level>
</settings>
<params/>
<script language="javascript">
<![CDATA[
function spooler_process()\{
var thisOrder = spooler_task.order;
var order = spooler.create_order();
var execute_jobchain = thisOrder.params.value("execute_jobchain");
order.id = thisOrder.id + "_next" ;
order.params.merge(thisOrder.params);
spooler.job_chain( execute_jobchain ).add_order( order );
return true;
\}
]]>
</script>
<run_time/>
</job>
2. create a "sync job" named "sync" using the job wizzard in JOE
<job title="Synchronize Job Chains"
order="yes"
tasks="1"
enabled="yes"
>
<description>
<include file="jobs/JobSchedulerSynchronizeJobChains.xml"/>
</description>
<params/>
<script language="java"
java_class="sos.scheduler.job.JobSchedulerSynchronizeJobChains"
java_class_path=""/>
<run_time/>
</job>
3. Create a job chain JobchainSampleChainNext with n nodes and add a node with sync job.
<job_chain orders_recoverable="yes"
visible="yes"
>
<job_chain_node state="100"
job="job_sample_4"
next_state="sync"
error_state="error"/>
<job_chain_node state="sync"
job="Sync"
next_state="success"
error_state="error"/>
<job_chain_node state="success"/>
<job_chain_node state="error"/>
</job_chain>
4. Create a job chain sampleNestedJobchain. One node is assigned to CallJobchain. This node sets the parameter execute_jobchain=JobchainSampleChainNext. The sync job is the succesor of this node.
<job_chain orders_recoverable="yes"
visible="yes"
>
<job_chain_node state="100"
job="job_sample_1"
next_state="200"
error_state="error"/>
<job_chain_node state="200"
job="job_sample_2"
next_state="callNext"
error_state="error"/>
<job_chain_node state="callNext"
job="CallJobchain"
next_state="sync"
error_state="error"/>
<job_chain_node state="sync"
job="Sync"
next_state="300"
error_state="error"/>
<job_chain_node state="300"
job="job_sample_3"
next_state="success"
error_state="error"/>
<job_chain_node state="success"/>
<job_chain_node state="error"/>
</job_chain>
