Maintaining a sequential data set

You might want to maintain a sequential data set for loading your AD and OI databases, because:

1. It is a backup that you can use if you lose the databases.
2. You can use it when you use IBM Z Workload Scheduler for the first time, if you already have application descriptions in some format that you can convert.
3. You might find it convenient to use the ISPF editor to change the control statements.
4. You can easily delete and re-create your AD and OI databases, for example, if you are new user of IBM Z Workload Scheduler and are developing naming standards.
