Background Job Introduction

 

What is Background job?

A Background job is a job that runs in background without effecting the normal operations of the system.

Advantages of Background Jobs

• It reduces manual effort & automates the task.
• It can be scheduled as per user’s choice.
• It reduces user interaction and can run seamlessly in the background without user input
• Once you define the variant for background job, the user doesn’t have to worry about value input in the field. Thus, user confusion is also reduced.
• Ideal for time- consuming/resource intensive programs which can be scheduled to run in the night(when system load is low).

 
 

 Background jobs are classified into three categories –

• Class A (High/critical Priority): – Some tasks are urgent or critical and must be scheduled with class A priority job. Class A priority reserves one or more background work processes. Users have to decide how many background work processes should be assigned to Class A priority job. Suppose a user chooses 2 background work processes for this category then available background work processes for class B and C = (Total number of work processes set in operation modes RZ03)- (Background work processes allowed to class A category).
• Class B(Medium Priority): – Once Class A jobs are completed , Class B job will start executing in the background before class C jobs.
• Class C(Low Priority): -It runs after both class A and class B jobs are completed.

 

Possible status of background jobs

1. Scheduled: – You have defined the program name and variant but not defined start condition like Start Date, End Date, Frequency etc. That means you have not defined when a job should be scheduled in system.
2. Released: – All required criteria are fulfilled for job definition. Start condition is must for the job to be in release status.
3. Ready: – All the required conditions are met to run the job in a background workprocess. But job scheduler has put the job in the queue because it is waiting for background workprocess to be free.
4. Active: – Job has started running in the background. We cannot change the status of the job once it is in Active status.
5. Finished: – Job is executed successfully. It means the desired task is competed without any error.
6. Cancelled: – There are two possibilities for this. The Administrator has forcefully canceled the job or there might be some issue with job. You can investigate this from Job logs.
