Setback intervals based on exit codes
If you want to set different setback intervals depending on the exit code then you can use the internal API by defining a post-processing routine after the task.
In this example, we define a job in a job chain.
- When the job ends with exit code 1 then try again in 60 seconds
- When the job ends with exit code 444 then try again in 2 hours
- When the job ends with other non-zero exit codes then try again in 300 seconds
Perform the following tasks with JOE:
- Define a post-processing function spooler_task_after()
- Code the switch with your requirements.
- Add the job to a job chain. Do this even you only have one job in the chain.
XML Configuration of the Job
<job order="yes">
<script language="shell"><![CDATA[
exit 0
]]></script>
<monitor name="handleSetback" ordering="0">
<script language="javax.script:ecmascript"><![CDATA[
function spooler_task_after() {
var exit = spooler_task.exit_code();
var job = spooler_task.job();
// After one setback, handle this as an error.
job.set_max_order_setbacks( 1 );
switch ( exit ) {
case 0: // proceed
return true;
case 1: // Restart after 60 seconds
job.set_delay_order_after_setback( 1, "60" );
break;
case 4444: // Restart after 2 hours
job.set_delay_order_after_setback( 1, "02:00:00" );
break;
default: // Restart after 300 seconds
job.set_delay_order_after_setback( 1, "300" );
break;
}
}
]]></script>
</monitor>
<run_time/>
</job>
XML configuration of the Job Chain
<job_chain>
<job_chain_node state="100"
job="job1"
next_state="success"
error_state="error"
on_error="setback"/>
<job_chain_node state="success"/>
<job_chain_node state="error"/>
</job_chain>
