Script Jobs

• Job and order Parameters are exposed

...

• to shell scripts as environment variables.
• Environment variables are named using a predefined prefix and the name of the original parameter: 
  • The default value for the environment variable prefix is SCHEDULER_PARAM_ . 
  • Environment variable names are provided with uppercase letters.
  • For example, a parameter param1 can be accessed by the SCHEDULER_PARAM_PARAM1 environment variable. This syntax applies for both job and order parameters.
    

  • For details see Which environment variables are provided by JobScheduler?

Examples for parameters defined for a job

The following two examples show a job parameter defined in a job <param> tag can be used in a shell script. Note that the parameter could have been equally well have been defined in the order.

 <job>
    <params>
        <param name="param1"  value="Test"/>
    </params>
    <script language="shell">
        <![CDATA[
 rem This

...

 is an example shell script to show the use of parameters
 echo Param1 has the value %SCHEDULER_PARAM_PARAM1%
        ]]>
    </script>
    <run_time/>
 </job>

 <job>
    <params>
        <param name="param1" value="Test"/>
    </params>
    <script language="shell">
        <![CDATA[
 # This is an example shell script to show the use of parameters
 echo "Parameter param1 has the value $SCHEDULER_PARAM_PARAM1"
        ]]>
    </script>
    <run_time/>
 </job

Examples for parameters defined on job start

The following example shows an XML command to start a job with parameters.

 <start_job job="my_job">
    <params>
        <param name="param1"  value="Test"/>
    </params>
 </start_job>

• A parametrized job start can be used programmatically, e.g. by use of the JobScheduler start script.
• Such parametrized job starts can be effected by JOC.

• How to pass parameters to subsequent jobs in a job chain.
