You create the sequence job in the Designer client and add stages. Tariq Awan Oct 25th, If the master sequencer job does not exist in the project, it is placed in the following default location: The master sequencer job uses the text file as an input and reads the list of sequencer jobs from the file. Start Loop activity properties The Start Loop stage marks the beginning of the loop and defines it.

You will recall that sequencer jobs invoke and run other jobs.

Sequence job activities

Specifying the value of the parameter each time that you run the sequence job ensures that you use the correct resources, such as the database datsatage connect to and the file name to reference.

Creating a Master Sequencer Job To create a sequecner sequencer job using the master sequencer utility: Member Since Jan Jan 10th, After you design your sequence job by adding activities and triggers, you define the properties for each activity. If this sequence job runs successfully, the success trigger causes the Overnightrun sequence job to run. Sequencre create a master sequencer job using the master sequencer utility:.

Sequencer Activity Stage is stage that is used to control and coordinate the flow of execution in a Job Sequence. As with stages, you can define job parameters for each activity.

The file path you specify should be local to the server; do not specify a path to a client machine. To view the properties of an activity, open the activity from the Designer client canvas.

As previous posts already pointed out, there are only two modes: Use the Enter the Jobname field to enter the name of the new master sequencer job.

Priyanka Mar 10th, Sequence job activities Sequence jobs contain activities, which are special stages that indicate the actions that occur when the sequence job runs.

However, the control comes to the 2nd job only after the 1st job has run pass or fail. Ensure that each job is entered on a separate line. Nested condition activity properties Use a Nested Condition stage to further branch the execution of sequejcer sequence job, depending on a condition.

Creating sequence jobs You create sequence jobs by dayastage activities, linking the activities, specifying triggers for each activity, and optionally adding parameters for each activity. 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.

Sequence job activities

The properties of each activity depend on the type of activity that you work with. The master sequencer utility is available in the following DataStage folder: The properties that you define control the behavior of the activity. 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. Job Activity properties Use the Job Activity stage to specify information about the job that the job activity seqeuncer.

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.

Sequencer activity properties You use the Sequencer stage to synchronize the control flow of multiple activities in a job sequence. Building sequence jobs For more complex designs, you can build sequence jobs to run multiple jobs in conjunction with other jobs.
