SVTVDR - Virtual Tape Volume Dismount Request File

At the DETAIL timespan, the Virtual Tape Volume Dismount Request File provides information about virtual tape volume dismounts.
micsrm140
The Virtual Tape Volume Dismount Request File is derived from the VTSS user SMF record, subtype 14. The subtype 14 record is produced when a VTV dismount event occurs, and contains metrics on number of bytes written to the virtual volume and the compression ratio achieved.

File Organization

The following table 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.

Usage Considerations

The SVTVDR and Virtual Tape Volume Mount Request (SVTVMR) files can be merged to determine tape drive occupancy time.

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 example, a database identifier of P is used. The identifier is installation-dependent, so you should find out what the identifiers are at your installation.
