Please Turn OFF your swquencer blocker. If the Demo job fails, the Failure trigger causes the Failure sequence job to run. A sequencer allows catastage to synchronize the control flow of multiple activities in a job sequence. Use the Sequencrr the Jobname field to enter the name of the new master sequencer job.
Priyanka Mar 10th, Specifying triggers Triggers determine what actions an activity takes when it runs as part of a sequence job. Also, the sequencer jobs you select should be compiled and ready for use.
All means all incoming triggers must be true and Any means at least one needs to be true. Note the file path of the text file for later use. You mean to say we cant run daatstage 2nd job if 1st job is failed? For example, if you have 5 jobs which hare interdependentthen you would call them from a sequencer.
You specify the control information, such as the different courses of action to take depending on whether a job in the sequence succeeds or fails. To create a master sequencer job using the master sequencer utility:. General activity properties After you design your sequence job by adding activities and specifying triggers, you enter the details that determine how each activity operates.
Sequencer activity properties You use the Sequencer stage to synchronize the control flow of multiple activities in a job sequence. Examples of using the sequencer stage Start Loop activity properties The Start Loop stage marks the beginning of the loop and defines it. After you create a sequence job, you schedule it to run using the InfoSphere DataStage Director client, just like you would with a parallel job or server job.

Terminator activity properties A terminator stage can be placed in a job sequence to ensure that the sequence is stopped cleanly if certain situations arise. For example, you can create a master sequencer job to automatically invoke and run 20 sequencer jobs from the Receivables mart.
You can test the parameters in the trigger expressions, and pass the parameters to other activities in the sequence job. The master sequencer utility is available in the following DataStage folder: The following sequence job shows a sequence that runs the Demo job. TOP Related.
