Loome Integrate is used to execute jobs that consist of a sequence of tasks.
When viewing the tasks of a job, the ‘Sequenced Tasks’ list shows the tasks that have been added to this job and the order that they will run in.
With this in mind, Loome Integrate jobs can be seen as a list of tasks that will execute individually in order.
If you wish to add a task that doesn’t exist yet, clicking the New Task button in the page header will take you to the new task form. Once you submit the new task, it will automatically be added to the sequenced tasks for the related job. Learn more about adding new tasks here.
Tasks that are created in the same project can be re-used across multiple jobs. A task created in one job can be added to other jobs. These tasks are called ‘Available Tasks’ and are at the bottom half of the page for each job.
To add an existing task to a job, select the tasks you want to add with the + button in the ‘Available Tasks’ list.
It will be added to the sequenced tasks of that job.
Using the drag handles on the left of the tasks, you can easily drag and drop tasks in the order you wish them to be executed.
You can view which agent is attached to a particular task on the job page. This will display the agent that a task will use and will also display whether this agent is healthy or unhealthy.
It can be viewed beside the task’s last modified date.
On the right side of the task sequence entry, you will notice there are a few actions that can be used to configure the task sequences even more.
These include (from left to right):
Sequenced tasks that are ‘Enabled’ will be run as part of the job. When unchecked, the sequenced task will be skipped for future job executions until it is enabled again.
Tasks are enabled by default. If you click on the toggle, it will enable/disable the task and change whether it will be included in the sequence when the task is run.
When a job runs, by default a failed task will not stop latter tasks from executing. By configuring task dependencies, tasks can require earlier steps in a job run to succeed before it can run. If any dependency fails, the tasks execution will be considered a failure.
You can manage the dependencies of a task using the Manage Dependencies action button on the right of the task.
Certain task types allow for parameters to be set when the task is sequenced. This allows for the same task to be re-used across different jobs with different configurations.
Task parameters in Loome Integrate will always be treated as a
varchar, this means your tasks must explicitly
convert parameter values to other types such as numeric types explicitly.
Clicking the “Edit Parameters” button allows you to edit the parameter values for that particular task sequence.
In some cases your task parameter values will be shared across multiple jobs. Rather than providing the same values multiple times, you can easily provide Parameter Defaults in the task create/edit form.
Parameter Defaults will only be used when there has been no parameter value provided for the tasks usage in a job.
If we used a simple Powershell script as an example, where
$Name refers to a parameter with the same name:
Write-Output "Hello $Name";
We could map the defaults and values to an output like so:
You can edit a task directly from the sequence list by clicking the “Edit Task” button.
Editing the task in the sequence will affect the task in all jobs. If you don’t wish to affect other jobs that use the task, it may be worth either creating a new task or cloning the task you wish to edit.
Click on the trash button on the task sequence to remove it from the job sequence. Removing the task from the sequence does not delete the task and you can re-add the task to the job sequence from the Available Tasks list.
