In case your job does not run successfully, you should fix the error and rerun the job. In case of failed jobs, there is a possibility that some tables have been loaded, altered or partially loaded. You need to rerun the job to get all the data and to remove any duplicate or missing data.
Two techniques that can be used for recovery are as follows −
Automatic Recovery − This allows you to run unsuccessful jobs in recovery mode.
Manually Recovery − This allows you to rerun the jobs without considering partial rerun previous time.
To run a job with Recovery option enabled in Designer
Step 1 − Right Click on job name → Execute.
Step 2 − Save all changes and Execute → Yes.
Step 3 − Go to the Execution tab → Enable Recovery check box. If this box is not checked, Data services will not recover the job, if it fails.
To run a job in Recovery mode from Designer
Step 1 − Right click and execute the job as above. Save changes.
Step 2 − Go to the Execution Options. You have to ensure that the option Recover from last failed execution box is checked.
Note − This option is not enabled, if a job is not yet executed. This is known as Automatic recovery of a failed job.
