Editing Scheduler Settings

You can edit scheduler settings for both non-reusable and reusable schedulers.

¨ Non-reusable schedulers. When you configure or edit a non-reusable scheduler, check in the workflow to allow the schedule to take effect.

You can update the schedule manually with the workflow checked out. Right-click the workflow in the

Navigator, and select Schedule Workflow. Note that the changes are applied to the latest checked-in version of the workflow.

¨ Reusable schedulers. When you edit settings for a reusable scheduler, the repository creates a new version of the scheduler and increments the version number by one. To update a workflow with the latest schedule, check in the scheduler after you edit it.

When you configure a reusable scheduler for a new workflow, you must check in both the workflow and the scheduler to enable the schedule to take effect. Thereafter, when you check in the scheduler after revising it, the workflow schedule is updated even if it is checked out.

You need to update the workflow schedule manually if you do not check in the scheduler. To update a workflow schedule manually, right-click the workflow in the Navigator and select Schedule Workflow. The new schedule is implemented for the latest version of the workflow that is checked in. Workflows that are checked out are not updated with the new schedule.

Disabling Workflows

You may want to disable the workflow while you edit it. This prevents the Integration Service from running the workflow on its schedule. Select the Disable Workflows option on the General tab of the workflow properties. The

Integration Service does not run disabled workflows until you clear the Disable Workflows option. Once you clear the Disable Workflows option, the Integration Service reschedules the workflow.

Scheduling Workflows During Daylight Savings Time

On Windows, the Integration Service does not run a scheduled workflow during the last hour of Daylight Saving

Time (DST). If a workflow is scheduled to run between 1:00 a.m. and 1:59 a.m. DST, the Integration Service resumes the workflow after 1:00 a.m. Standard Time (ST). If you try to schedule a workflow during the last hour of

DST or the first hour of ST, you receive an error. Wait until 2:00 a.m. to create a scheduler.

Manually Starting a Workflow

Before you can run a workflow, you must select an Integration Service to run the workflow. You can select an

Integration Service when you edit a workflow or from the Assign Integration Service dialog box. If you select an

Integration Service from the Assign Integration Service dialog box, the Workflow Manager overwrites the

Integration Service assigned in the workflow properties.

You can manually start a workflow configured to run on demand or to run on a schedule. Use the Workflow

Manager, Workflow Monitor, or pmcmd to run a workflow. You can choose to run the entire workflow, part of a workflow, or a task in the workflow.

You can also use advanced options to override the Integration Service or operating system profile assigned to the workflow and select concurrent workflow run instances.
