Dataset Compress dialog box

You use this dialog box to issue the DFSMSdss COMPRESS command to compress the data sets that you selected 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:

Run as DFSMSdss Administrator: Select this option to cause the command to run with Administrator authorization in DFSMSdss. The user ID that you are using must be authorized as a storage administrator in DFSMSdss.
Dynamic Allocation: Select this option to cause the command to use dynamic allocation for the affected data sets.

With OMEGAMON® for Storage on z/OS® Version 4.2.0 Interim Feature 3 or later, you can select *VOL@*DSNG or *VOL@*DSNAG as an attribute of the command variable on the Command tab of the Dataset Compress dialog box. *VOL@*DSNG represents the volume attribute of each dataset in the dataset group and is resolved at job submission. *VOL@*DSNAG represents the volume attribute of each dataset in the dataset attribute group and is resolved at job submission. Note that *VOL@*DSNG and*VOL@*DSNAG attributes should be used in conjunction with *DSNG and *DSNAG, respectively. When you click the Show Data button, the dialog box displays the group name (for the extension subject) and the slave subject name.
