Job execution

Jobs can be started in multiple ways. The job’s status defines how you can start the job. You can start the job if the job’s status is In Queue or Free.

In Queue status

If the job’s status is In Queue, you can use the Job Daemon to start the job. You must start the Job Daemon before the daemon can activate any job.

The implementation of the Job Daemon depends on the operating system of the LN server:

  • On a UNIX server
    The Job Daemon is the shell program rc.startjobdm, which is located in the ${BSE]/etc directory. To start the Job Daemon, you can include the ${BSE}/etc/rc.startjobdm command in the ${BSE}/etc/rc.start file. As a result, the Job Daemon is activated when you start the LN environment.
  • On a Windows server
    The Job Daemon is a service that you can manage by means of the Application Services Manager (ASM)

When the Job Daemon runs, you can stop the Virtual Machine (VM) without any problem. The Job Daemon, and not your VM, carries out the job.

To run a job for multiple companies, you must start a Job Daemon for each company.

See Job handling procedure.

Free status

If the job’s status is Free, you can start the job in the following ways:

Activate Job (ttaad5203m000)

If you start the job before the time and date of execution, the job’s status changes to Waiting. While the job is being carried out, the job’s status changes to Running. Because the Virtual Machine (VM) of the user who starts the job carries out the job, the user cannot quit the VM until the job is finished.

If a job that belongs to more than one company must be started, you must use the Change Company command on the Menu browser’s Option menu to switch to the required company.

The rc.startjob shell command (UNIX)

You can also start the job with the UNIX ${BSE}/etc/rc.startjob shell script. For this purpose, you must enter the following syntax at the UNIX prompt: ${BSE}/etc/rc.startjob [job name].

You can include the rc.startjob script in a UNIX user job scheduler (crontab), which can automatically start jobs. For this purpose, some UNIX variables must be defined in the shell script. For more information, see the shell script.

To run a job for multiple companies, you must create a unique version of rc.startjob for each company.

The startjob.bat batch file (Windows)

If LN runs on a Windows server, you can also start the job with the startjob.bat batch file.

To start a job, you must enter the following syntax at the Windows command prompt: startjob.bat [job name]

Before you can enter this syntax, you must run the fillenv.bat batch file to set the LN environment variables.

To automate the execution of jobs, you can run startjob.bat with a scheduler.

To run a job for multiple companies, you must create a unique version of startjob.bat for each company.

See Job handling procedure.

Job status

The following table lists the statuses a job can have during its life span:

StatusDescription
FreeThe job’s basic job data is defined and is ready to be started.
RunningThe job is started and is running.
Waiting

The job is started and is waiting to be carried out at the next execution date and time.

The Job Daemon will not start the job.

In queueThe job is queued and will be started automatically when the Job Daemon runs.
BlockedThe job is blocked and cannot be started. To start the job, set the status to Free or In Queue.
CanceledThe job has been stopped with the Cancelar tareas (ttaad5204m000) session. A job is also canceled when the maximum duration is exceeded.
Runtime errorThis status signals an error during the execution of the job.

 

If required, you can cancel a job that the Job Daemon starts, for example, to change the job’s basic job data. To cancel the job, use the Tareas (ttaad5500m000) session. On the Vistas, Referencias o Acciones menu, click Cancel Job. If you cancel a job, the current session of the running job is carried out, but the following sessions in the job will not be started. The job’s status changes from In Queue to Canceled. To restart a canceled job, you must release the job to change the job’s status to In Queue or Free.

To temporarily stop a job, start the Tareas (ttaad5500m000) session. On the Vistas, Referencias o Acciones menu, click Block Job.
