1. 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 <br />How do you pass the parameter to the job sequence if the job is running at night?<br />You can insert the parameter values in a table and read them when the package runs using ODBC Stage or Plug-In stage and use DS variables to assign them in the data pipeline, or pass the parameters using DSSetParam from the controling job (batch job or job sequence) or Job Control Routine from with DS or use dsjob -param from within a shell script or a dos batch file when running from CLI.Above answer was rated as good by the following members:<br />Two ways<br />1. Ste the default values of Parameters in the Job Sequencer and map these parameters to job.<br />2. Run the job in the sequencer using dsjobs utility where we can specify the values to be taken for each parameter.<br />You can insert the parameter values in a table and read them when the package runs using ODBC Stage or Plug-In stage and use DS variables to assign them in the data pipeline or pass the parameters using DSSetParam from the controling job (batch job or job sequence) or Job Control Routine from with DS or use dsjob -param from within a shell script or a dos batch file when running from CLI.<br />RE: what are validations you perform after creating jobs in designer.what r the different type of errors u faced during loading and how u solve them Hi I worked on a process which was loading target table after performing email standardization on source files.I performed the following validations:1)all letters should be in smallcase2)email id field should not contain more than 255 characters3)it should not contain special characters except underscoreWhile loading sometimes i came across to the following errors:1)quot;
unknown field name.....quot;
because metadata was not properly loaded..i reloaded the data and it worked fine...2)quot;
data truncaion warningquot;
..bcoz in data stage data type size was less than the size of data type in database <br />Data Vaidations NULL checkMetaData CheckDuplicate CheckInvalid Check <br />DataStage Technical Questions1.
