# Dataset Alter dialog box

You use this dialog box to issue an IDCAMS ALTER request to alter the data sets and catalogs that you select in the Tivoli® Enterprise Portal. To learn about the standard capabilities of a dialog box, see Standard tabs in the dialog boxes of the Storage Toolkit. The topic includes a link to the Reference guides for commands that are used in the Storage Toolkit.

The dialog box provides the following options:

- Fully Qualified Name: Specifies a new, fully-qualified name for the data set that you have selected. If you have selected multiple data sets, this field is disabled. Other fields in the dialog box continue to be available.
- Catalog: Specifies a new name for the catalog that contains the entry.
- Management class: For SMS-managed data sets only, this option specifies a new name for the management class for a data set. The name must come from a list of names that the system administrator defines.
- Storage class: For SMS-managed data sets only, this option specifies a new name for the storage class. The name must come from a list of names that the system administrator defines.
