Job Sequencing in Data Stage
Job Sequencing
It is Controlling the order of execution.
Master Job
Can run multiple jobs with the same name
Trigger
Checking the compilation of job 1, if it is compiled without errors, then job 2 is compiled.
Error handling
This situation arises when Job is Aborted
Notification
When everything is successful, we should get a confirmation mail that it is Successful.
Wait for file
Waits for the file, until it is searched and gets loaded into the source.
Checkpoints
If a job is aborted in between by any chance, check point make sure that the job starts from the point where it has failed.
Parameter Mapping
We cannot use a parameter defined in 1 job to another job, TO do this we use parameter Mapping.
Job sequencing Stages are categorized into 4 groups
- Run stages
- Flow control stages
- Error handling stages
- Other stages
