Besides predefined job tasks, you can define your own job tasks by writing code to be included in OS and SQL scripts. The advantages of using these scripts include:

• When defining these jobs, you can use target properties.

• When defining these jobs, you can use the job library, which enables you to share the job and make updates as issues arise. However, you need to resubmit modified library jobs for them to take effect.

• You can submit the jobs against multiple targets.

• You can submit the jobs against a group. The job automatically keeps up with changes to group membership.

• For host command jobs, you can submit to a cluster.
