The PowerShell Command Line Interface is available from GitHub at https://github.com/sos-berlin/scheduler-cli-powershell

Short Description

The JobScheduler Command Line Interface (CLI) can be used to control JobScheduler instances (start, stop, status) and job-related objects such as jobs, job chains, orders, tasks.

The JobScheduler CLI module supports Windows PowerShell 3.0 and newer.

Long Description

The JobScheduler Command Line Interface (CLI) is used for the following areas of operation:

...

The responses from a JobScheduler Master can include large XML answers.
Such answers are stored in temporary files, the debug message indicates the location of the file.
The threshold for creating temporary files is 1000 byte by default.
Consider use of the Set-JobSchedulerOption -DebugMaxOutputSize cmdlet to change this value.

How to get started with the JobScheduler CLI

The JobScheduler CLI is used for JobScheduler instances that are installed
locally or on remote computers and is initialized by the following commands:

• Import Module
  • PS C:\> Import-Module JobScheduler
    • loads the module from a location that is available with the PowerShell module path,
    • see $env:PSModulePath for predefined module locations.
  • PS C:\> Import-Module C:\some_module_location\JobScheduler
    • loads the module from a specific location, absolute and relative paths can be used.
  • Hints
    • You can add the command Import-Module JobScheduler to your PowerShell profile to have the module loaded on start of a PowerShell session, see PowerShell CLI 1.1 - Use Cases - Credentials Management
• Use JobScheduler Master Instance
  • As a first operation after importing the module it is required to execute the Use-JobSchedulerMaster or Use-JobSchedulerWebService (starting from release 1.11) cmdlets.

  • PS C:\> Use-JobSchedulerMaster <Url>   or   PS C:\> Use-JobSchedulerMaster -Url <Url>   or   PS C:\> Use-JobSchedulerWebService -Url <Url> -Id <JobSchedulerId>
    • specifies the URL for which the JobScheduler Master or REST Web Service is available. This is the same URL that you would use when opening the JOC Cockpit GUI in your browser, e.g. http://localhost:4446. If you omit the protocol (HTTP/HTTPS) for the URL then HTTP will be used. The -Id parameter specifies the JobScheduler ID of the Master that you intend to connect to.
    • allows to execute cmdlets for the specified Master independently from the server and operating system that the JobScheduler Master is operated for, i.e. you can use PowerShell cmdlets on Windows to manage a JobScheduler Master running on a Linux box and vice versa. As an exception to this rule you cannot start a remote JobScheduler Master and you cannot start a remote JobScheduler Windows service, however, you can restart, terminate, abort and suspend any JobScheduler Master on any platform.
    • specifying the URL is not sufficient to manage the Windows Service of the respective Master, see below.
  • PS C:\> Use-JobSchedulerWebService -Url <Url> -Id <JobSchedulerID>
    
    • references the JobScheduler ID that has been assigned during installation of a Master.
    • adds the JobScheduler ID to the assumed installation base path.
      
      • A typical base bath would be C:\Program Files\sos-berlin.com\jobscheduler
      • The path is added the subdirectory with the value of the JobScheduler ID
  • PS C:\> Use-JobSchedulerMaster -InstallPath <InstallationPath>
    • specifies the full installation path, e.g. C:\Program Files\sos-berlin.com\jobscheduler\scheduler1.10, for a locally available JobScheduler Master.
  • PS C:\> Use-JobSchedulerMaster -InstallPath $env:SCHEDULER_HOME
    • You can use the environment variable SCHEDULER_HOME that points to the installation path.
    • The JobScheduler CLI module on import checks availability of this environment variable.
  • PS C:\> Use-JobSchedulerMaster -Url <Url> -Id <JobSchedulerID>
    
    • specify both URL and JobScheduler ID (recommended).
    • determines if the Master with the specified JobSchedulerID is locally available.
  • Hints
    • If your JobScheduler Master is configured to require HTTP authentication then please consider that
      • by default the Windows credentials of the current user are forwarded for web requests.
      • individual credentials can be added by use of the following cmdlet Set-JobSchedulerCredentials.
      • For details and examples see PowerShell CLI 1.1 - Use Cases - Credentials Management
• Manage JobScheduler Objects
  • PS C:\> Show-JobSchedulerStatus
    • shows the summary information for a JobScheduler Master
  • PS C:\> Get-JobSchedulerOrder
PS C:\> Get-JobSchedulerJobChain
PS C:\> Get-JobSchedulerJob
PS C:\> Get-JobSchedulerTask
    • retrieves the list of avaiable objects
  • see the complete list of cmdlets with the cmdlet: Get-Command -Module JobScheduler

How to run JobScheduler commands

JobScheduler commands are Windows PowerShell scripts (.ps1 files), so you can run
them at the command line, or in any editor.

...

• Get-Help Use-JobSchedulerMaster -detailed
• Get-Help Show-JobSchedulerStatus -detailed
• etc.

Examples

Find some typical use cases for the JobScheduler CLI.

• Perform an emergency stop:
  • Get-JobSchedulerTask | Stop-JobSchedulerTask
  • This will terminate all running and enqueued tasks immediately.
• Find enqueued tasks, i.e. tasks that are scheduled for a later start:
  • Get-JobSchedulerTask -NoRunningTasks
  • Retrieves the list of scheduled tasks.
• Suspend any temporary orders that are e.g. created by job scripts:
  • $orders = ( Get-JobSchedulerOrder /my_jobs -NoPermanent | Suspend-JobSchedulerOrder )
  • This will retrieve temporary ad hoc orders from the /my_jobs directory and any subfolders.
  • All temporary orders are suspended and the list of order objects is stored in a variable.
• Remove orders based on a list that has previously been retrieved:
  • $orders | Remove-JobSchedulerOrder
  • This will remove the orders available from the list.

Managing the JobScheduler Master

Find some use cases for JobScheduler Master management.

• Start the JobScheduler Master:
  • Start-JobSchedulerMaster -Service
  • Starts the Windows service of a JobScheduler Master
• Start the JobScheduler Master in paused mode:
  • Start-JobSchedulerMaster -Service -Pause
  • The Windows service is started and is immediately paused to prevent any tasks from starting.
• Restart the JobScheduler Master:
  • Restart-JobSchedulerMaster -Timeout 120
  • Restarts the Master having left any running tasks up to 120 seconds to complete.
• Stop the JobScheduler Master immediately:
  • Stop-JobSchedulerMaster -Action kill
  • This will kill all running tasks immediately and terminate the JobScheduler Master.
• Stop the JobScheduler Master cluster:
  • Stop-JobSchedulerMaster -Cluster -Action abort
• Install the JobScheduler Master Windows service:
  • Install-JobSchedulerService -Start -PauseAfterFailure
  • Installs and starts the Windows service. Should a previous JobScheduler run have been terminated with failure then the JobScheduler Master will switch to paused mode.
  • This allows e.g. to check for enqueued tasks before starting operations.
  • A previously installed Windows service with the same name will be removed.
• Install the JobScheduler Master Windows service for a specific account:
  • Install-JobSchedulerService -Start -UseCredentials
  • This will install the Windows service and ask for the name of the account and password that the service is operated for. The account name typically includes the domain and user, e.g. .\some_user for some_user in the current domain.
• Remove the JobScheduler Master Windows service:
  • Remove-JobSchedulerService
  • This will remove the Windows service. Should any tasks be running with the JobScheduler Master then the removal will be delayed. 
  • Consider to use Stop-JobSchedulerMaster -Action abort if immediate removal of the Windows service is required.
