2.1.1 TLM Component Database Concepts

Raw data for the TLM component is collected by the TMCC
collector, described in Appendix C.  The TMCC collector
builds a common format raw data file from information in the
targeted tape library internal database.  This common format
raw data file is subsequently input into the TLM component
daily update DAY091 step.  A best practice is to run a TMCC
raw data collection once daily to provide a daily snapshot of
the tape data sets and volumes managed by the library.

The TLM component provides the same database file structure
and content, regardless of the tape management product used.
This common database structure allows the component files to
be used to satisfy similar requirements for any z/OS-based
tape management system.  It also minimizes disruption for
sites that transition from one tape management system to
another.

Tape management systems provide tools designed to support the
day-to-day operational requirements of the tape library.  The
CA MICS database file structure and content provide a
repository that can help determine if the library is being
used as efficiently as possible.  The database can also serve
as a basis for capacity planning for tape library resources,
and can meet cost accounting requirements for tape media
storage.
