Dataset information panel
File-AID/MVS identifies a multi-volume data set with the MULTI-VOLUME DATASET message in the upper-right hand corner, the Press ENTER for multiple volumes message located above the Current Allocation information, and a + (plus) sign following the volume serial number. When you press Enter, File-AID/MVS displays the Volume Serial Numbers pop-up window identifying the first 40 volumes allocated to this data set. See Dataset Information Screen for Multi-Volume Data sets and Dataset Information Screen for Multi-Volume Data sets.
Catalog name
Catalog location of the data set.
Dataset name
Fully qualified name of the data set.
General Data:
Volume serial
Serial number of the storage device. For multi-volume data sets, File-AID displays only the first volume.
Device type
Type of storage device on which the data set resides.
Organization
Access method of the data set, .
Record format
File-specific code:
F - Fixed length
V - Variable length
U - Undefined format
B - Blocked
A - ANSI printer control characters
M - Machine code printer control characters
S - For Sequential data sets only: Standard for F or spanned for V.
T - Track-overflow feature.
Option code
Access method-dependent processing options.
Key length
Number of bytes in the key.
Record length
Maximum number of bytes per logical record (LRECL).
Block size
Maximum number of bytes per physical record (BLKSIZE).
1ST extent blocks/tracks/cylinders
Size of primary space in specified space units.
Secondary blocks/tracks/cylinders
Size of the secondary space in specified space units.
Encryption Information:
Encrypted (Y/N)
Identifies if the data set is encrypted.
Keylabel
Identifies the name, up to 64 bytes, of the keylabel to be used to encrypt the new data set.
Current Allocation:
Allocated blocks/tracks/cylinders
Total size of the allocated data set.
Allocated extents
Number of primary and secondary extents specified at allocation.
Allocated dir. blocks
Number of directory blocks specified at allocation.
Current Utilization:
Used blocks/tracks/cylinders
Storage currently occupied by data set.
For data sets allocated in blocks, the space is calculated from all blocks used. This includes any partial "short" blocks.
Used extents
Number of primary and secondary allocations in use.
Used dir. blocks
Number of directory blocks in use.
Number of members
Number of active directory entries for a PDS.
Dataset Date Information:
Creation
Date on which the data set was allocated.
Expiration
Date after which deletion or update of data set is permitted.
Last referenced
Date on which the file was last opened.
SMS Information:
Storage class
Data set’s hardware requirements.
Data class
Attribute information, such as RECFM, DSORG, LRECL, and BLKSIZE.
Management class
Data set migration, backup, and retention information.
Extended attributes
A dataset with extended attributes can be stored in the Extended Address Space (EAS) on an Extended Attribute Volume (EAV).
Valid values are as follows:
- O (Opt)—Extended attributes are optional
- N (No)—No extended attributes
- BLANK—Extended attributes are not specified
PDSE Information:
Dataset name type
Type of SMS Managed Partitioned data set. This information is available only on DFP 3.2 or above. Valid values are:
Library
New type of partitioned data set; it is also called a PDSE. It has unlimited directory blocks and reuses its own space. PDSE libraries do not need to be compressed.
PDS
Standard partitioned data set.
Large
Large sequential data set (requires z/OS 1.7 and up). The initial allocation of the data set does not have to exceed 65,535 tracks; the combined space allocated by primary and secondary allocations is allowed to exceed 65,535 tracks when the data set is allocated as LARGE. There is still a limit of 16 extents for data set allocation.
Data sets defined with DSNTYPE=LARGE can be either SMS or non-SMS managed.
blank
Data set is not partitioned.
Dataset Version
Specifies the PDSE version number (Valid for a PDSE only). 1 = Version 1, 2 = Version 2.
Maximum Generations
Maximum number of generations specified at allocation time.
