Common Tape System (CTS)
Macros, utility programs, and a z/OS multi-tasking address space which provide a common interface for CA-1 and CA TLMS. Allowing CA and other OEM products to use the same interface to both products.
controlling data set
The data set that determines the retention or movement of a volume or a set of chained volumes. This is the first data set on the volume chain by default.
count field
The part of the retention command where you can specify a number of days. This number will be used with retention methods 2, 3, 4, 5, 8, B, and C.
crash
When a system becomes unusable. Caused either by a hardware malfunction or a software problem.
crash protection
Protects volumes currently in use against reuse if an operating system failure occurs.
criteria

CTS
Common Tape System.
cycle
One version of a data set. Other versions of the data set are created by multiple executions of the same job. The most recently created data set is cycle 1. The rest of the data sets are numbered sequentially in order by descending creation date and time.
data set
A group of logically related records stored together and given a unique name.
data set group
Two or more data sets that start with the same characters.
default
A value or action automatically supplied by the computer system unless you specify some other alternative.

ESV
Error Statistics by Volume. A facility of the operating system which provides extended statistical information from CLOSE/EOV to the external gummed label generator and to the CA TLMS volume master file update routines.
exit

expired
A data set with a keep date less than the current (system) date.
expires
The retention criteria have been satisfied and the tape is available for scratch.
External Data Manager (EDM)
A computer product which has direct control of storage volumes. CA TLMS ensures that only the EDM accesses its tapes. CA TLMS does not record dataset or chaining information for an EDM, nor will it scratch an EDM volume through TRS. The EDM ID is stored in the VMF OWNER field.
external gummed labels
Labels that can be pasted on tapes with information on the volume and the data sets contained on the volume.
file sequence number
Identifies the order in which a data set appears on a tape volume or volumes. FILESEQ=2 means that this data set is the second data set on the volume(s).
foreign volumes
All tape volumes not under the control of CA TLMS.
fully qualified
Identifying a data set by its complete data set name.
high-water mark
The maximum number of resources required for one job step.
initialization commands
Initialize the VMF by defining tape ranges and specifying certain processing options.
input data set name verification
An optional feature that extends data set name validation from the system default of the last 17 characters to the entire 44-character data set name.
in-service
Indicates that the volume is physically usable.
keep date
An internal date, calculated by CA TLMS when a data set is created. It can be used as one of the criteria by which a volume is scratched or moved.
LMP
License Management Program.
location commands
Add records to the RMF describing the data center and each off-site storage location.
mixed operating system environment
More than one of these operating systems: MVS, VSE and VM.
move date
An internal date established by CA TLMS when a volume is moved to a new location. It can be used as one of the criteria by which a volume is retained or moved.
movement
Moving tapes from the data center to a storage location or from one storage location to another.
multi-data set volume
A volume that contains more than one data set.
multivolume data set
A data set that spans two or more tape volumes. All volumes are automatically chained together.
nonscratch
Indicates that the controlling data set is still active and the volume is not ready to be reused for output.
off-site storage location
A place to store tapes that is either physically or logically removed from the data center.
online recorder
The TLMS subtask running under CTS that controls the realtime processing of CA TLMS and provides data set protection, volume protection, and auxiliary message handling.
out-of-service
Indicates that a tape volume is physically unusable.
owner
The ID of the External Data Manager (EDM) which controls a tape volume. See External Data Manager.
partially qualified
Identifying a group of data sets by some of the characters at the beginning of their data set names.
preferred date
The external date format which CTSDATE should use by default. This format is set when CTSDATE is opened or by SET format command. The CA TLMS default is MM/DD/YYYY, but most reports and displays can set their own preferred format.
prefix
Alphabetic characters at the beginning of a VSN.
qualifiers
A group of characters at the beginning of a data set name.
range
Tape volumes with contiguous volume serial numbers.
realtime stacking
Allows users to take advantage of the increased capacity of new tape media types by stacking files that normally fit on a single volume onto a multivolume file when directed to a scratch pool with stacking enabled.
retention
A period of time during which a data set is protected. During this period, the data set cannot be scratched or overwritten.
retention commands
Add records to the RMF defining retention and movement for specific data sets, groups of data sets, or all data sets that are not covered by specific commands.
Retention Master File
A VSAM file which contains all location and retention records and, therefore, controls the retention and movement of all tape data sets under CA TLMS control.
Retention Schedule
A group of fields in the VMF record which contain one to six locations and rules for retaining a volume set.
RMF
Retention Master File.
SCHED
This is a UPV command keyword which may be used to manually update the RTN-SCHED field in the VMF.
scratch
Indicates that a tape volume is available for reuse, either because the retention criteria have been satisfied or because the scratch indicator in the VMF has been manually changed from nonscratch to scratch.
shared DASD
DASD devices that can be accessed by multiple CPUs simultaneously.
skip-tapes commands
Exclude tapes from a range when defining tape ranges in the VMF.
SMS
IBM's Storage Management Subsystem.
tape retention system
The component of CA TLMS that controls the retention and movement of tape data sets, protecting them for a user-specified retention period and then returning the tape volumes to the scratch pool for reuse when the retention period has ended.
TRS
Tape retention system.
user exits
Computer instructions that allow you to modify the software package's code to meet your data center's needs.
user tables
A collection of data which you can use to specify limits on a data set or a defined portion of it. For example, with the user pool table, you can restrict certain data set prefixes to a specific volume serial number range.
VMF
See Volume Master File.
VOLSER

Volume Master File (VMF)
A file containing volume and data set information for each volume in the tape library. Auxiliary messages and control information may also be in the VMF.
