In the Mainframe Navigation view, the z/OS datasets are shown when you expand the Datasets folder of a z/OS node.
This document covers the following topics:
Before displaying z/OS datasets, you can define a filter so that only those datasets are shown which correspond to your filter criteria.
To define a filter
In the Mainframe Navigation view, select the Datasets folder in the appropriate node.
Invoke the context menu and choose
.Or:
Press F3.
The following dialog box appears:
Enter the filter criteria.
Option | Description |
---|---|
Dataset name | Enter the datasets that are to be shown. For example, when you specify "ABC*", only the dataset names starting with these characters will be shown. |
Volume |
If you do not specify a volume, the dataset list is created from the catalog. If you do specify a volume, the dataset list is created from the VTOC of that volume. |
Password | Enter the system password if dataset is protected. |
Choose the
button.You can compress a partitioned z/OS dataset (PDS).
To compress a z/OS dataset
In the Mainframe Navigation view, select a partitioned dataset either in the Datasets or Volumes folder of the appropriate node.
Invoke the context menu and choose
.A dialog box appears, asking to confirm the compress function for the selected object.
Choose the
button to compress the dataset.You can display information about a z/OS dataset.
To display the properties of a z/OS dataset
In the Mainframe Navigation view, select a dataset in the Datasets folder.
Invoke the context menu and choose
.Or:
Press ALT+ENTER.
A properties dialog box appears.
The following information is shown on the Server page of the properties dialog box:
Option | Description | |
---|---|---|
Volume | Serial number of the volume on which the dataset is allocated. | |
Device type | If a volume is not specified, this is the generic identifier from which a volume is to be selected (e.g. 3380). | |
Organization | For example: | |
PO | PDS | |
PS | Sequential dataset | |
DA | Direct access | |
Record format | For example: | |
FB | Fixed block | |
VB | Variable block | |
FBA | Fixed block, ANSI control characters | |
Record length | Logical record length in bytes. | |
Block size | Block size in bytes. | |
Allocation type | Space type for dataset. Possible values: | |
BLK | Blocks | |
CYL | Cylinders | |
TRK | Tracks | |
First extent | Initial quantity allocated. | |
Second extent | Additional quantity to be allocated if dataset fills. | |
Security | Security status. Possible values: | |
NONE | Not password-protected. | |
READ | Password-protected for read and write operations. | |
WRITE | Password-protected for write operations. | |
Allocated cylinders/tracks | Number of cylinders or tracks allocated. | |
Allocated extents | Number of extents, 1 to 16. | |
Percentage used | Percentage of dataset used. | |
Creation date | Dataset creation date in format YYYY-MM-DD. | |
Last reference | Date of last access in format YYYY-MM-DD. | |
Expiration date | Date when the dataset expires in format YYYY-MM-DD. Until this date is reached, each attempt to update or delete the dataset causes a console message, requiring an operator reply. | |
Partitioned dataset | These fields appear only if the dataset is partitioned. | |
Number of members | Number of members in the dataset. | |
Directory blocks | Number of directory blocks. | |
Unused blocks | Number of unused directory blocks. | |
SMS attributes | These fields appear only if SMS attributes have been defined for the dataset during allocation. | |
Management class | The management class used to obtain the management-related data for SMS (migration, backup and retention criteria) to allocate the dataset. | |
Storage class | The storage class used to obtain the storage-related data for dataset allocation. | |
Data class | The data class used to obtain the data-related information (SPACE, LRECL, etc.) for dataset allocation. |
