You use this dialog box to issue the DFSMSdss RELEASE command to release
allocated but unused space from all data sets on the selected volumes. 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 following parameters are available:
- Minimum secondary allocation for release (n number of tracks, where n ranges
from 0 to 99999999)
- Minimum unused space prior to release (n number of tracks, where n ranges
from 0 to 99999999)
- Wait time in seconds between retry attempts (n seconds, where n ranges
from 0 to 255)
- Number of attempts allowed to obtain volume access (n tries, where n ranges
from 0 to 99)
- A fully-qualified data set name or pattern for data sets
that you want to exclude from the space release operation. Use the Fully
Qualified Dataset Name or Pattern table to manually enter data set names
or DSN patterns.
