Scope

  • JobScheduler is evolving towards an architecture that allows more flexible use with Agents.
  • Find an overview of supported languages for jobs that make use of COM components.

Language Overview

MasterAgent
LanguageArchitectureLanguageArchitectureComments
VBScript

JVM 64bit + Master 64bit

  • call 64bit components, e.g. COM
  • access to 64bit registry
ScriptControl:VBScript

No support for JVM 64bit + Agent

  • Agent can be used with JVM 32bit and 64bit
  • ScriptControl is available for 32bit only
  • COM objects can be instantiated from 32bit architectures
  • Users of VBScript jobs on a Master 64bit should migrate to PowerShell Jobs for Agents
 JVM 32bit + Master 32bit
  • call 32bit components, e.g. COM
  • access to 32bit registry 
 JVM 32bit + Agent
  • call 32bit components, e.g. COM
  • access to 32bit registry 
  • ScriptControl works as a compatibility mode for VBScript Jobs
  • Minor syntactical changes to job scripts required
  PowerShell

JVM 64bit + Agent

  • call 64bit components, e.g. COM
  • access to 64bit registry
  • COM objects can be instantiated from both 32bit and 64bit architectures
  • The architecture of the JVM in use determines if 32bit or 64bit COM components are referenced
   JVM 32bit + Agent
  • call 32bit components, e.g. COM
  • access to 32bit registry
 
  dotnet (.NET)same architectures as PowerShell
  • Jobs can be implemented in any .NET language by use of the Job Implementation Interface
  • FEATURE AVAILABILITY STARTING FROM RELEASE 1.10.7


Examples

  • Examples are available for download from scripting.zip
  • Unzip the archive in the ./config/live folder of your JobScheduler Master, a sub-directory scripting will be created for job-related objects.

COM component for example jobs

  • From the attached archive scripting.zip register the COM component ComComponent.dll that implements a sample class. The .dll has been compiled using the AnyCPU model and has to be registered by the user.
  • Register the COM component for your respective architecture. The path to the .NET Framework might be different for your environment:
    • 32bit
      • C:\Windows\Microsoft.NET\Framework\v4.0.30319\regasm.exe ComComponent.dll /codebase /tlb /nologo
    • 64bit
      • C:\Windows\Microsoft.NET\Framework64\v4.0.30319\regasm.exe ComComponent.dll /codebase /tlb /nologo
  • To later on remove the registration use
    • regasm.exe ComComponent.dll /u

VBScript jobs calling COM components

VBScript job for Master

  • This example works for a JobScheduler Master 32bit and 64bit
  • The above COM component ComComponent.dll has to be registered for the respective architecture
Master runs VBScript that calls a COM component
<job  title="Master runs VBScript that calls a COM component" order="no" stop_on_error="no" tasks="1">
    <params/ >
    <script language="vbscript">
        <![CDATA[
        Set fso = CreateObject ("Scripting.FileSystemObject")
        Set stdout = fso.GetStandardStream (1)
        Set stderr = fso.GetStandardStream (2)
    
        Dim objTest, intResult
        Set objTest = CreateObject ("ComComponent.ComClassExample")
        intResult = objTest.AddTheseUp (100, 200)
            
        stdout.WriteLine "running VBScript job: " & intResult
        ]]>
    </script>
    <run_time />
</job>

 

VBScript Job for Agent

  • This example works for a 32bit Agent
  • The above COM component ComComponent.dll has to be registered for the 32bit architecture
  • Basically the job script is the same as for the Master, consider use of the language scriptcontrol:vbscript and the assignment of a process class that points to an Agent.
Agent runs VBScript that calls a COM component
<job  title="Agent runs VBScript that calls a COM component" order="no" stop_on_error="no" tasks="1" process_class="Agent">
    <params />
    <script  language="scriptcontrol:vbscript">
        <![CDATA[
        Set fso = CreateObject ("Scripting.FileSystemObject")
        Set stdout = fso.GetStandardStream (1)
        Set stderr = fso.GetStandardStream (2)
    
        Dim objTest, intResult
        Set objTest = CreateObject ("ComComponent.ComClassExample")
        intResult = objTest.AddTheseUp (100, 200)
            
        stdout.WriteLine "running VBScript job: " & intResult
        ]]>
    </script>
    <run_time />
</job>

PowerShell jobs calling COM components

PowerShell Job for Agent

  • This example works for Agents with a JVM 32bit and 64bit.
  • The above COM component ComComponent.dll has to be registered for the respective architecture.
  • For details on the use of the JobScheduler API see PowerShell Jobs.
Agent runs PowerShell that calls a COM component
<job  title="Agent runs PowerShell that calls a COM component" order="no" stop_on_error="no" tasks="1" process_class="Agent">
    <params />
    <script  language="powershell">
        <![CDATA[
$objTest = New-Object -ComObject "ComComponent.ComClassExample"
$intResult = $objTest.AddTheseUp(100, 200)
            
echo "running PowerShell job: $intResult"
        ]]>
    </script>
    <run_time />
</job>
