Starting a job chain from within a running job chain and handing over parameters programmatically can be effected with the following steps.

Display feature availability
StartingFromRelease1.7

The start of additional job chains can be configured within the current job chain configuration, see How to configure workflow control by return code handling. The below information is intended for users who want to apply scripting for an individual solution.

Create a job CallJobChain

Code Block
languagexml
titleconfiguration of the CallJobChain job
collapsetrue
 <job order="yes">
    <params/>
    <script language="javax.script:ecmascript"><![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>

Create a synchronization job with the name sync

...

Code Block
languagexml
titleConfiguration of the sync job
collapsetrue
 <job title="Synchronize Job Chains"
     order="yes">
    <description>
        <include file="jobs/JobSchedulerSynchronizeJobChains.xml"/>
    </description>
    <params/>
    <script language="java"
            java_class="sos.scheduler.job.JobSchedulerSynchronizeJobChains"
            java_class_path=""/>
    <run_time/>
 </job>

Create a job chain JobchainSampleChainNext with some nodes and add a node with a synchronization job

Code Block
languagexml
titleConfiguration of the job chain JobchainSampleChainNext
collapsetrue
 <job_chain>
    <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>

...

One node is assigned to CallJobChain. This node sets the parameter execute_jobchain to the value JobchainSampleChainNext. The synchronization job is the succesor of this node.
