Managing Sequences on a Nominode

Managing Sequences on a Nominode

Sequences are used to schedule one or more Tasks to execute at specific times on a recurring basis.  Sequences are also used allow one Task to begin execution after another Task completes its execution, rather than at a specific time.

Creating a Sequence

  1. Click on Sequences on the left hand navigation menu of your Nominode.
  2. Set the Select Project field at the top of the page to the Project* that you would like to associate the new Sequence with. 
  3. Click on the Create Sequence button in the upper right hand corner of the page.
  4. Type in a name for your Sequence.
  5. Select whether or not your Sequence will be enabled initially.
  6. Set a schedule for when your Sequence will execute using a Cron Expression.
  7. Alternatively, select another Sequence that will trigger your new Sequence to execute when it completes execution.
  8. Select a Task to add to your Sequence under ADD NODE WITH TASK on the righthand side of the page.
  9. Click the blue Add button under your Task selection.
  10. If desired, repeat steps 8 and 9 to add additional Task nodes to your Sequence.
  11. Newly added Task nodes will be stacked on top of each other.  Click and drag each node for visual separation.
  12. Hold shift and click on a Task node, then drag your mouse pointer to another Task node to make the initiation of the Task in the second node dependent on the completion of the Task in the first node.
  13. Multiple Tasks can be set to depend on the completion of a single Task and single Task's initiation can depend on the completion of a multiple Tasks.  Other more complex chains can be created, as well, allowing some tasks to run in parallel at a step in a Sequence while other tasks run serially.  However, the creation of a circular Task dependency chain is not allowed.
  14. Once you have finished adding Task nodes and creating dependency chains in your Sequence, click on the Save button at the bottom of the page.

*Projects are discussed in more detail in the Nominode Permissions Overview support document.  Steps to create a new Project are also available.
