SVTCIP - Channel Interface Performance File

At the DETAIL timespan, the Channel Interface Performance File contains statistics related to channel activity associated to the VTSS.
micsrm140
The Channel Interface Performance File is derived from the VTSS user SMF record, subtype 11, 'VTSS Channel Interface Performance'. This record is produced on an interval basis, typically every 15 minutes. The SVTCIP file contains statistics on I/O throughput and channel capacity between the host and the VTSS, and the VTSS to the RTD's (Real Tape Devices).

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

Up to 32 channels can be defined. Channels can be defined or installed but not actually enabled. Data element Channel Interface Enabled, CICPE, can be used to determine channel status.
If channel was enabled during the interval, CICPE has a value of one (1). At higher timespans, CICPE indicates the number of intervals the channel was enabled. In addition, data element Type of Link (CIPTOL) indicates the type of channel, whether it services the host or the real tape drives.

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.
