SVTVMV - Virtual Tape Volume Movement File

At the DETAIL timespan, this file records the movement of a Virtual Tape Volume from one multivolume cartridge to another. It is derived from the VTSS user SMF record, subtype 26, 'VTV Movement'. This record is produced on an event basis every time a virtual tape volume is moved from one MVC to another.

File Organization

The table below identifies data elements by which the file is sequenced and summarized in each timespan. N/A indicates that the file is not supported in a timespan. At the DETAIL level, data is sequenced but not summarized.
The timespans in which a file is supported are defined by each installation when
MICS
is installed. Therefore, this table has been generated as part of the installation process to accurately reflect the
MICS
system at your installation.

This file was generated with ESSENTIAL=ALL option in effect. All data elements that are defined in the file are generated.
This file was generated with DERIVED=DEFault option in effect. The complex definition of the DERIVED option controls whether the data elements are kept on the file on auxiliary storage.

Usage Considerations

The SVTVMV file contains statistics useful in determining the amount of time and resources spent moving virtual tape volumes from one multivolume cartridge to another. This activity is generally automated by the VSM when consolidating or reclaiming MVC's to make the best use of the resource (similar to defragmenting a hard drive).
This activity uses real tape drives and should be monitored to ensure it is not occurring during heavy virtual volume recall times. If so, it might be degrading workload performance.

Retrieval Examples

In the examples, a SAS macro variable is used to specify the DDname part of the
MICS
file name. These macro variables are a standard part of
MICS
and are available for all files. The macro variable name has the form &diiit, where d is the database identifier, iii is the information area name, and t is the timespan. For the examples, a database identifier of P is used. The identifier is installation-dependent, so you should find out what the identifiers are at your installation.
No report examples are available at this time for this file.
