Syntax

Start-JobSchedulerJob.ps1 [-Job] <String> [[-Parameters] <String>] [[-At] <String>] [[-Id] <String>] [[-Url] <Uri>] [[-Credentials] <PSCredential>] [[-Separator] <String>] [<CommonParameters>]

Help

To display help information execute the following commands:

  • Windows
    • Get Help Overview
      • pwsh.exe -c ./Start-JobSchedulerJob.ps1 -?
    • Get Detailed Help
      • pwsh.exe -c Help ./Start-JobSchedulerJob.ps1 -Detailed
  • Linux, MacOS
    • Get Help Overview
      • ./Start-JobSchedulerJob.ps1 -?
    • Get Detailed Help
      • pwsh -c Help ./Start-JobSchedulerJob.ps1 -Detailed

Functionality

  • The script is executable from the command line
    • for Windows by use of the pwsh.exe PowerShell interpreter like this:
      • pwsh.exe -f ./Start-JobSchedulerJob.ps1 -Job /bjb/shell_job1
    • for Linux and MacOS by directly calling the script and by implictly using the shebang (#!/usr/bin/pwsh) to reference the interpreter like this:
      • ./Start-JobSchedulerJob.ps1 -Job /bjb/shell_job1
  • Use of JobScheduler PowerShelll CLI
    • Code

      Start-JobSchedulerJob.ps1
      #!/usr/bin/pwsh

      )
      
      if ( !$Id )
      {
          throw "missing value for parameter -Id"
      }
      
      if ( !$Url )
      {
          throw "missing value for parameter -Url"
      }
      
      if ( !$Credentials -and !$Url.UserInfo )
      {
          throw "missing value for parameter -Credentials"
      }
      
      Import-Module JobScheduler
       
      if ( $Url.UserInfo )
      {
          $ws = Use-JobSchedulerWebService -Url $Url -Id $Id
      } else {
          $ws = Use-JobSchedulerWebService -Url $Url -Id $Id -Credentials $Credentials
      }
       
      try
      {
          $job = Start-JobSchedulerJob -Job $Job -At $At -Parameters ( ConvertFrom-StringData -StringData $Parameters.Replace($Separator, "`n") )
      } catch {
          throw $_.Exception
      } finally {
          $ws = Use-JobSchedulerWebService -Url $Url -Id $Id -Disconnect
      }
    • Explanations
      • Basically the script is about the following operations:
        • Import the JobScheduler Module
        • Connect to the JOC Cockpit REST Web Service
        • Start an job with the JobScheduler Master
        • Disconnect from the JOC Cockpit REST Web Service
      • Follow above instructions about getting help to see detailed information about parameters
