Which job do you want to add? Another sequential job or a parallel job? However , in both the cases there are mainly 2 easy ways: Add a “Job Activity” stage. Sequencer. Multiple inputs and multiple outputs. 11 here we are executing Trigger Stage that is job finished with no errors/ Warnings. Sequencers are job control programs that execute other jobs with preset Job DataStage The sequencer operates in two modes:ALL mode.

Use the Choose the Master Sequence Type field to specify the mode in which you want the sequencer jobs to be run. The master sequencer utility is available in the following DataStage folder: These actions are computation tasks that are written dztastage Jaql, MapReduce, or other frameworks that you use to write applications to seequencer large amounts of data.

Interview Candidate May 24th, 6 Ensure that each job is entered on a separate line. Designing sequence jobs Designing a sequence job is similar to designing a parallel job.

Only staging sequencer jobs can be run in parallel. However, in case, if you want to execute next job even though all the incoming triggers are False, then Seqencer is NOT the solution.

Building sequence jobs

Sequencer Activity Stage is stage that is used to control and coordinate the flow of execution in a Job Sequence. Specifying sequeencer value of the parameter each time that you run the sequence job ensures that you use the correct resources, such as the database to connect to and the file name to reference.

As with stages, you can define job parameters for each activity. If this sequence job runs successfully, the success trigger causes the Overnightrun sequence job to run. The file path you specify should be local to the server; do not specify a path to a client machine.

Sequence job activities Sequence jobs contain activities, which are special stages that indicate the actions that occur datastae the sequence job runs.

Showing Answers 1 – 6 of 6 Answers. The utility does not provide annotations for the master sequencer job, but you can provide annotations if you wish. After you design your sequence job by adding activities and triggers, you define the properties for each activity. User variables activity properties Use the user variable stage to define global variables within a sequence. Specifying triggers Triggers determine what actions an activity takes when it runs as part of a sequence job.

The properties that you define control the behavior of the activity. Designing a sequence job is similar to designing a parallel job. You create the sequence job in the Designer client and add stages.

Examples of using the sequencer stage

All means all incoming triggers must be true and Any means at least one needs to be true. In this mode, output triggers can be fired if any of the sequencer inputs are TRUE. This site uses cookies to deliver our services and to show you relevant ads and job listings. Start Loop activity properties The Start Loop stage marks the beginning of the loop and defines it.

Notification activity properties Use the Notification stage to specify information about an email notification activity. If the master sequencer job does not exist in the project, it is placed in the following default location: A sequencer allows you to synchronize the control flow wequencer multiple activities in a job sequence.

Examples of using the sequencer stage

Sequencer activity properties You use the Sequencer stage to synchronize the control flow of multiple activities in a job sequence. You interact with activities in the same way that dxtastage interact with stages in parallel jobs and sequdncer jobs. The stages that you add are known as activities. As the name suggests, it is basically to execute the jobs in sequence.

When you run the sequence job, specify a runtime value for the environment variable. When you link two activities together, you define the triggers that define the flow of control.

Creating a Master Sequencer Job To create a master sequencer job using the master sequencer utility: This stage can have multiple input triggers and multiple output triggers.


In the Parameters tab, use the Enter Source text file Name field to enter the file path for the text file you created in step three. By using sequence jobs, you can integrate programming controls into your job workflow, such as branching and looping.

As previous posts already pointed out, there are only two modes: Nested condition activity properties Use a Nested Condition stage to further branch the execution of a sequence job, depending on a condition.

Tariq Awan Oct 25th, Restarting sequence jobs Sequence jobs record checkpoint information so that you can restart some sequence jobs if they fail. Also, the sequencer jobs you select should be compiled and ready for use.

Please Turn OFF your ad blocker. For that you need to set the trigger option to unconditional. Valid values are Parallel or Sequential. Ensure you select the proper mode for the sequential jobs included in the master sequencer. Copy the list seauencer sequencer jobs and paste the names into a text file.

The job sequence includes properties and dafastage have parameters, which are passed to the activities in the sequence job. You must compile the master sequencer job before you can use it.

Member Since Jan Jan 10th, You specify the control information, such as the different courses of action to sequnecer depending on whether a job in the sequence succeeds or fails. You can test the parameters in the trigger expressions, and pass the parameters to other activities in the sequence sequncer. If a master sequencer job with the same name already exists in the project, it is overwritten and placed in the same category.
