You can use locks to prevent a job start, while another job is running. You can find some informations about looks at http://www.sos-berlin.com/doc/en/scheduler.doc/lock.xml
Locks are defined in files in the hotfolder (live). The name of the file is the name of the lock followed by .lock.xml. E.g. lockSample.lock.xml
Using locks, you have to
- declare a lock
- assign the lock to the involved jobs
Example
the lock
<locks>
<lock name="lockSample"/>
</locks>
two jobs, assigned to the lock
<?xml version="1.0" encoding="ISO-8859-1"?>
<job order="yes"
stop_on_error="no"
name="jobsSample_1">
<lock.use lock="lockSample"
exclusive="yes"/>
<script language="shell">
<![CDATA[
echo here is the job jobsSample_1
echo I'm not running in parallel with job jobsSample_2
ping -n 60 localhost
]]>
</script>
<run_time/>
</job>
<?xml version="1.0" encoding="ISO-8859-1"?>
<job order="yes"
stop_on_error="no"
name="jobsSample_2">
<lock.use lock="lockSample" exclusive="yes"/>
<script language="shell">
<![CDATA[
echo here is the job jobsSample_2
echo I'm not running in parallel with job jobsSample_1
ping -n 60 localhost
]]>
</script>
<run_time/>
</job>
Two job chains using the jobs
<?xml version="1.0" encoding="ISO-8859-1"?>
<job_chain orders_recoverable="yes"
visible="yes"
name="job_chain1">
<job_chain_node state="100"
job="jobsSample_1"
next_state="success"
error_state="error"/>
<job_chain_node state="success"/>
<job_chain_node state="error"/>
</job_chain>
<?xml version="1.0" encoding="ISO-8859-1"?>
<job_chain orders_recoverable="yes"
visible="yes"
name="job_chain2">
<job_chain_node state="100"
job="jobsSample_2"
next_state="success"
error_state="error"/>
<job_chain_node state="success"/>
<job_chain_node state="error"/>
</job_chain>
Two orders assigned to the job chain
<?xml version="1.0" encoding="ISO-8859-1"?>
<order job_chain="job_chain1"
id="test_lock1">
<run_time let_run="no"/>
</order>
<?xml version="1.0" encoding="ISO-8859-1"?>
<order job_chain="job_chain2"
id="test_lock2">
<run_time let_run="no"/>
</order>
