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.

Oozie workflows are a collection of actions that are arranged in a control dependency.

Sequence job activities

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. This site uses cookies to deliver our services and to show you relevant ads and job listings. Creating sequence jobs You create sequence jobs by adding activities, linking the activities, specifying triggers for each activity, and optionally adding parameters for each activity. Specifying triggers Triggers determine what actions an activity takes when it runs as part of a sequence job.

The utility does not provide annotations for the master sequencer job, but you can provide annotations if you wish. Showing Answers 1 – 6 of 6 Answers. The master sequencer utility uses only sequencer jobs as input; please do not use server jobs as input. Ensure that each job is entered on a separate line.

Sequence job properties Sequence jobs contain basic properties just like parallel jobs and server jobs. These actions are computation tasks that are written in Jaql, MapReduce, or other frameworks that you use to write applications to process large amounts of data.

Priyanka Mar 10th, When you run the sequence job, specify a runtime value for the environment variable. First Prev Next Last.

Sequencer Activity Stage is stage that is used to control and coordinate the flow of execution in a Job Sequence. For that you need to set the trigger option to unconditional. The master sequencer job uses the text file as an input and reads the list of sequencer jobs from the file. Sequence job activities Sequence jobs contain activities, which are special stages that indicate the actions that occur when the sequence job runs.


The sequencer operates in two modes: Specify these characteristics to determine how your sequence job runs. Job Activity properties Use the Job Activity stage to specify information about the job that the job activity runs. Sequence jobs contain activities, which are special stages that indicate the actions that occur when the sequence job runs.

Designing DataStage and QualityStage jobs. You interact with activities in the same way that you interact with stages in parallel jobs and server jobs.

To view the properties sequenncer an activity, open the activity from the Designer client canvas. For example, you can create a master sequencer job to automatically invoke and run 20 sequencer jobs from the Receivables mart.

What are Sequencers?

If this sequence job runs successfully, the success trigger causes the Overnightrun sequence job to run. Once the master sequencer job is imported into your project, you can move it to another category. You can also add jobs or routines to your design as activities by dragging the associated icon from the Designer client Repository and dropping it on your sequence job canvas.

Click the Run button to generate the master sequencer job. The properties of each activity depend on the type of activity that you work with. Sequencer activity properties You use the Sequencer stage to synchronize the control flow of multiple activities in a job sequence. The master sequencer utility is available in the following DataStage folder: Creating environment variables in your sequence jobs You can define an environment variables as a job parameter to use in your sequence jobs.


It looks like you are using an AD Blocker! Valid values are Parallel or Sequential. 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.

All means all incoming triggers must be true and Any means at least one needs to be true. Copy the list of sequencer jobs and paste the names into a text file. Also, the sequencer jobs you select should be eatastage and ready for use. It can have multiple input triggers as well as multiple output triggers. If a master sequencer job with the same name already exists in the project, it is overwritten and placed in the same category. Yes you can run the 2nd job even if the first one fails.

By using sequence jobs, you can integrate programming controls seuqencer your job workflow, such as branching and looping. What if I wanna run 2nd job if 1st job got failed out of 4 jobs. The job sequence includes properties and can have parameters, which daastage passed to the activities in the sequence job. Tariq Awan Oct 25th, General activity properties After you design your sequence job by adding activities and specifying dataatage, you enter the details that determine how each activity operates.

Building sequence jobs

Only staging sequencer jobs can be run in parallel. End Loop activity properties The end loop stage marks the end of the loop. The stages that you add are known as activities. A sequencer allows you to synchronize the control flow of multiple activities in a job sequence.
