Datastage: DataStage Scenario's

Scenario based Question ........... Suppose that 4 job control by the sequencer like (job 1, job 2, job 3, job 4 )if job 1 have 10,000 row ,after run the job only 5000 data has been loaded in target table remaining are not loaded and your job going to be aborted then.. How can short out the problem.Suppose job sequencer synchronies or control 4 job but job 1 have problem, in this condition should go director and check it what type of problem showing either data type problem, warning massage, job fail or job aborted, If job fail means data type problem or missing column action .So u should go Run window ->Click-> Tracing->Performance or In your target table ->general -> action-> select this option here two option
(i) On Fail -- commit , Continue
(ii) On Skip -- Commit, Continue.
First u check how many data already load after then select on skip option then continue and what remaining position data not loaded then select On Fail , Continue ...... Again Run the job defiantly u get successful massage

Question: I want to process 3 files in sequentially one by one how can i do that. while processing the files it should fetch files automatically .

Ans:If the metadata for all the files r same then create a job having file name as parameter then use same job in routine and call the job with different file name...or u can create sequencer to use the job..

--------------------------------------------------------------------------------------------------------------------------------------

Parameterize the file name.
Build the job using that parameter
Build job sequencer which will call this job and will accept the parameter for file name.
Write a UNIX shell script which will call the job sequencer three times by passing different file each time.

RE: What Happens if RCP is disable ?

In such case Osh has to perform Import and export every time whenthe job runs and the processing time job is also increased...

--------------------------------------------------------------------------------------------------------------------

Runtime column propagation (RCP): If RCP is enabled for any job and specifically for those stages whose output connects to the shared container input then meta data will be propagated at run time so there is no need to map it at design time.

If RCP is disabled for the job in such case OSH has to perform Import and export every time when the job runs and the processing time job is also increased.

Then you have to manually enter all the column description in each stage.RCP- Runtime column propagation
