Task Center window | IBM VERSION 9 guide

To use the Task Center, you must first create a tools catalog. If you did not create a tools catalog when you installed DB2, you can select Tools —> Tools Settings —> Scheduler Settings and create one now.

Use the Task Center to run tasks, either immediately or according to a schedule, and to notify people about the status of completed tasks. The Task Center includes functionality from the Script Center in previous DB2 versions, plus additional functionality.

A task is a script, together with the associated success conditions, schedules, and notifications. You can create a task within the Task Center, create a script within another tool and save it to the Task Center, import an existing script, or save the options from a DB2 dialog or wizard such as the Load wizard. A script can contain DB2, SQL, or operating system commands.

For each task, you can do the following:

vSchedule the task

vSpecify success and failure conditions

vSpecify actions that should be performed when this task completes successfully or when it fails

vSpecify e-mail addresses (including pagers) that should be notified when this task completes successfully or when it fails

You can specify conditional coding by creating task actions. Each task action consists of a task and the action that should be performed on the task. For example, task 1 could have the following task actions:

vIf task 1 is successful, task action A enables the schedule for task 2.

vIf task 1 fails, task action B runs task 3.

You can also create a grouping task, which combines several tasks into a single logical unit of work. When the grouping task meets the success or failure conditions that you define, any follow-on tasks are run. For example, you could
