Define Space
- VOLUME NAME
- Enter the six character VOLID of the disk where the space should be defined.
- ALL FREE SPACE
- Specify whether you want all available space on the volume for VSE/VSAM:
- 1 - YES
- 2 - NO
If you specify 1 (YES), all free space (up to 16 extents) on the volume is dedicated to VSE/VSAM.
If you specify 2 (NO), a panel displays the free extents on the volume. Select one extent. Enter the beginning allocation and the amount of space to be allocated.
In some circumstances, VSE/VSAM rounds the specified values to a higher number. If the rounded extent exceeds the original one, the space definition fails. To avoid this, choose values which result in a smaller extent than the one shown.
- SPACE AVAILABLE TO CURRENT FILES
- Specify whether the files currently owned by the catalog can access the new space for
secondary allocation:
- 1 - YES
- 2 - NO
If you specify 1 (YES), the dialog alters the catalog entries of the current files so new space can be used for secondary allocation. The dialog changes the catalog entries, if:- The secondary allocation for the file is greater than 0.
- You define new space on disk devices with the same device type code as the primary allocation for the file(s).
If a current file already accesses space on a volume, it keeps that access when you define new space on the same volume.
If you specify 2 (NO), current files cannot access the new space.
- FAT-3390 DISK
- Specify extended space on a 3390 disk.
- 1 - YES
- 2 - NO
If you specify 1 (YES), the dialog defines up to 65520 cylinders of space (3390 ECKD only).
If you specify 2 (NO), the limit of 10017 cylinders is valid. You should specify NO for all other disks.
On the Job Execution panel, select:
2 - Immediate, Job is executed
Option 1 stores the job control statements in a VSE/ICCF library member in your default primary library. The default member name is F$xxxx, where xxxx is your user ID. You can change the name on the panel.
Option 2 automatically runs the job online. The terminal is locked until the job finishes. It also stores the VSE/ICCF member F$xxxx.P (xxxx is your user ID) in your default primary library. If there are no errors, the member contains one record with an asterisk (*). If errors occurred, the control statements and VSE/VSAM (Access Method Services) error messages are stored in this member. You are notified if you should review the contents of the library member.
- For CKD disk devices, the units of allocation are cylinders and not tracks.
- If you are using emulated FBA disks or virtual FBA disks, VSE/VSAM can use as VSE/VSAM space the first 4194240 blocks (2 GB) in units of 960 blocks.
- If you are using FBA-SCSI disks, VSE/VSAM can use as VSE/VSAM space the first 33546240 blocks (16 GB) in units of 30720 blocks. For further details, refer to Planning.
