PowerShell Scripting

PowerShell is a scripting shell of the Windows world. A PowerShell script can be used in jobs as easy as other shell scripts.

An example:

 <job title="Execute a PowerShell Script" order="yes" stop_on_error="no">
     <script language="shell"><![CDATA[
 echo SCHEDULER_DATA = %SCHEDULER_DATA%
 echo SCHEDULER_PARAM_SCRIPT_FILENAME = %SCHEDULER_PARAM_SCRIPT_FILENAME%
 
 powershell.exe get-ExecutionPolicy
 powershell.exe -nologo -NonInteractive -noprofile -file "%SCHEDULER_PARAM_SCRIPT_FILENAME%" "%SCHEDULER_PARAM_SCRIPT_FILENAME%"
 exit %errorlevel%
         ]]>
     </script>
     <monitor name="configuration_monitor"
              ordering="0">
         <script java_class="sos.scheduler.managed.configuration.ConfigurationOrderMonitor"
                 language="java"/>
     </monitor>
     <run_time/>
 </job>

This job is an order-driven job and therefore the parameter for this job comes from an order like that one below:

 <order title="Executes the File PowerShell-Hallo.ps1">
     <params>
         <param name="Script_Filename"
                value="${SCHEDULER_DATA}\config\live\PowerShell\Powershell-Hallo.ps1"/>
     </params>
     <run_time let_run="no"/>
 </order>

Within the order the value of the parameter Script_Filename, which specify the name of the script to be executed, will be passed to the job as an environment variable.

The script, which is executed in the above example, is as much as simple:

 $A="Hello, PowerShell ..."
 $A
 
 Write-Host "Num Args:" $args.Length;
 foreach ($arg in $args)
 {
   Write-Host "Arg: $arg";
 }
 
 Write-Host "Environment-var Scheduler-Data is : $env:SCHEDULER_DATA"
 Write-Host "Operating system is               : $env:OS"
 
 exit $lastexitcode
 
 # to change the policy for using powershell you can use this .adm file:

The output in the log-file looks like the text below:

 C:\Program Files (x86)\scheduler>echo SCHEDULER_DATA = C:/Program Files (x86)/scheduler  
 SCHEDULER_DATA = C:/Program Files (x86)/scheduler 
  
 C:\Program Files (x86)\scheduler>echo SCHEDULER_PARAM_SCRIPT_FILENAME = C:/Program Files (x86)/scheduler\config\live\PowerShell\Powershell-Hallo.ps1  
 SCHEDULER_PARAM_SCRIPT_FILENAME = C:/Program Files (x86)/scheduler\config\live\PowerShell\Powershell-Hallo.ps1 
  
 C:\Program Files (x86)\scheduler>powershell get-ExecutionPolicy 
 SCHEDULER-918  state=release
 RemoteSigned 
  
 C:\Program Files (x86)\scheduler>powershell -noprofile \
 -file "C:/Program Files (x86)/scheduler\config\live\PowerShell\Powershell-Hallo.ps1" \
 "C:/Program Files (x86)/scheduler\config\live\PowerShell\Powershell-Hallo.ps1"  
 Hello, PowerShell ...
