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.

This process generates the master sequencer job and stores it in the target file path you specified in step seven. Sequence job properties Sequence jobs contain basic properties just like parallel jobs and server jobs. Sequencers are job control programs that execute other jobs with preset Job parameters.

Sequence job activities

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. 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.

Sequence jobs contain activities, which are special stages that indicate the actions that occur when the sequence job runs. Use the Enter the Jobname field to enter the name of the new master sequencer job. You interact with activities in the same way that you interact with stages in parallel jobs and server jobs. For that you need to set the trigger option to unconditional.

Datastagd file path you specify should be local to the server; do not specify a path to a client machine. When you datasstage 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: 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.

Note the file path of the text file for later use. If the Demo job fails, the Failure trigger causes the Failure sequence job to run. Import the generated master sequencer job into your DataStage project.

It can accept multiple input triggers and multiple output trigger. For more complex designs, you can build sequence jobs to run multiple jobs in conjunction with other jobs. Sequencer activity properties You use the Sequencer stage to synchronize the control flow of multiple activities in a job sequence. By using sequence jobs, you can integrate programming controls into your job workflow, such as branching and looping. Rohit Soni Jul 20th, Please Turn OFF your ad blocker.

You create the sequence job in the Designer client and add stages. If the master sequencer job does not exist in the project, it is placed in the following default location: Identify the individual sequencer jobs you want to include in the master sequencer job.

Oozie workflows are a collection of actions that are arranged in a control dependency. You specify the control information, such as the different courses of action to take depending on whether a sequemcer in the sequence succeeds or fails. Exception activity properties An exception activity handles the situation where a job in the sequence fails to run other exceptions in the job sequence are handled by triggers.

What are Sequencers?

Use the Choose the Master Sequence Type field to specify the mode in which you want the sequencer jobs to be run.

You can test the datastxge in the trigger expressions, and pass the parameters to other activities in the sequence job. What if I wanna run 2nd job if 1st job got failed out of 4 jobs. The master sequencer job uses the text file as an input and reads the list of sequencer jobs from the file. Ensure you select the proper mode for the sequential jobs included in the master sequencer. Start Loop activity properties The Start Loop stage marks the beginning of the loop and defines it.

Valid values are Parallel or Sequential. Only staging sequencer jobs can be run in parallel. Member Since Jan Jan 10th,
