Info
  • Development of the SAPS4HANAJob template is has been completed and currently is on ice:  the the job template does not ship with current JS7 releases.
  • Our intention is to make the job template available for users who operate JS7 with its Open Source License, see JS7 - License.
  • To this purpose ongoing testing and adjustments to with new releases of the SAP REST API is required.
  • Interested parties who are ready to provide access to testing environments are invited to get in contact.

...

  • Manage job configuration
    • Map JS7 Jobs to SAP Jobs. SAP Jobs are integrated in JS7 Workflows.
    • JS7 Workflows allow cross platform execution of SAP jobs and any all other jobs executed with the same workflow across JS7 Agents on any all platforms.
    • JS7 job dependencies apply, e.g. for mutual exclusion by JS7 - Resource Locks.
    • JS7 error handling applies, e.g. for rerunning SAP Jobs and catching SAP Job errors.
  • Manage Calendars and Schedules
    • Automated starting of workflows for SAP Jobs based on JS7 Schedules.
    • Allowing cyclic job execution.
  • Maintain Job History
    • Recording job execution history with start time, end time, exit code etc. of SAP Jobs.
    • Maintaining SAP Job logs.

...

  • Monitor and control SAP Jobs from the JOC Cockpit user interface for browsers.
  • Monitor and control SAP Jobs from the JS7 JS7 - REST Web Service API and the JS7 - PowerShell Module.
  • Start SAP Jobs manually in addition to automated job starts from JS7 Schedules.
  • Visualize SAP Job logs.
  • Note: The SAP Job Scheduling Service does not allow to stop or to kill terminate running SAP Jobs.

Operational Features

  • Execute any number of parallel SAP Jobs with the same or different JS7 Agents:
    • Running separate SAP Jobs in parallel.
    • Running any number of instances of the same SAP Job in parallel.
  • Recover from loss of the connection to an SAP Job Scheduling Service:
    • SAP Jobs will continue to run in case of a connection loss between JS7 and an SAP system.
    • SAP Job execution results and logs can be recovered after the a connection is has been re-established.

Integration Scenario

...

  • A 1:1 mapping of a JS7 JITL Job and an SAP Job applies. This allows parameterization on a per job basis.
  • The JS7 JITL Job is added to JS7 - Workflows which are either configured:
    • to execute individual SAP Jobs or
    • to execute a number of jobs including SAP Jobs and any JS7 - Jobs with any registered JS7 Agent.
    • This allows cross-platform scheduling with SAP Jobs being integrated into a sequence of jobs that is executed for SAP systems and for other platforms.
  • The JS7 JITL Job makes uses JS7 - Calendars and Schedules.
    • The JS7 - Schedules determine the parameters and the point in time for at which the SAP Job is started.
    • SAP Jobs therefore are started immediately from the point of view of the SAP Job Scheduling Service. JS7 manages any schedules and connects to the SAP Job Scheduling Service at the point in time of job execution to launch the SAP Job.

...

The JS7 JITL Job acts as a shadow job for the SAP Job allowing . It allows user intervention such as starting or stopping an SAP Job by performing when the relevant operation on the JS7 JITL Job is performed from the GUI.

  • Starting the JITL Job causes the SAP Job to start.
    • Job parameters as available from the SAP Job configuration are forwarded when starting the SAP Job.
      • JS7 supports the following parameter data types: String, Number, Boolean.
      • The same applies to return values from SAP Jobs. Any return values of from SAP Jobs are available to subsequent JS7 jobs in a workflow.
  • Checking the JITL Job status and job logs returns the SAP Job status and log output with the JS7 JOC Cockpit GUI.
    • Note that the SAP REST API only offers job logs after execution.
    • Running logs, which typically available with JS7 jobs are not available from the SAP Job.
  • Stopping the JS7 JITL Job results in the relevant SAP REST API call to:
    • complete a running SAP Job and then to fail the JS7 Order:
      • Execution of JS7 - Orders can be cancelled by using the CANCEL operation from the JS7 GUI. This allows the currently executed current SAP Job to complete execution and removes the JS7 order from the workflow - provided that the SAP transaction implements the respective operation to cancel execution.
      • Execution of JS7 orders can be suspended by using the SUSPEND operation from the JS7 GUI.  This This allows the currently executed current SAP Job to complete execution and puts the JS7 order to a SUSPENDED state.
    • kill terminate running SAP Jobs:
      • Execution of JS7 orders can be cancelled with a KILL CANCEL option to abort the currently running SAP Job and to remove the JS7 order from the workflow, provided that the SAP transaction implements a cancel/kill force option.
      • Execution of JS7 orders can be suspended with a KILL CANCEL option to abort the currently running SAP Job and to put the JS7 order to a SUSPENDED state, provided that the SAP transaction implements a suspend/kill force option.
  • Error handling includes by the JS7 JITL Job includes checking execution results reported by the SAP REST API. If the execution is successful then the JS7 order will be continued. Otherwise the order has failed.
