1.1.2 Features

Major features of the TLM component are discussed below:

o TMCC Collector

  The TMCC Collector, provided with the TLM component and
  described in Appendix C, collects the tape data set and
  tape volume data processed by the TLM component.

  The TMCC Collector accesses tape management system catalogs
  and builds a raw data file that is subsequently processed
  by the TLM component daily update step.  The TMCC collector
  maintains a control data set that permits it to accurately
  determine megabyte/hour occupancy for individual tape data
  sets.

  All tape management systems share common characteristics
  and similar measurements.  The common format of the TMCC
  raw data file allows a single set of TLM component database
  files to be populated, regardless of the tape management
  system providing the data.  This permits ease of transition
  when migrating from one tape management system to another.

o General Product Functionality and Flexibility

  User Exits
  ----------
  A wide range of standard user exits support tailoring of
  individual database file content.  User exits are described
  in section 10.1, TLM User Exits.

  VOLGROUP Definition Routine
  ---------------------------
  A tape volume grouping (VOLGPRTE) routine supports the
  categorization and grouping of volumes by site-defined
  criteria using data element Volume Group (VOLGROUP).  The
  VOLGROUP data element is a summarization key for the TLM
  component data files.  Coding of this routine is discussed
  section 7.1.3.2, TLM VOLGROUP Definition Routine
  (VOLGPRTE).

  Organizational Ownership
  ------------------------
  An account code specification routine (TLMACCT) supports
  the definition of TLM component account codes, typically
  used to describe the organizational structure.

  An account code derivation routine (TLMACRT) assigns values
  to each defined account code for individual tape data set
  records based on user-specified criteria.  Both the TLMACCT
  and TLMACRT routines are described in section 7.1.2, TLM
  Component Complex Level Parameters.

  Scalability and Recoverability
  ------------------------------
  The TLM component supports standard CA MICS scalability and
  recovery options such as multiple work files, internal step
  restart, and incremental update.

  Database Tailoring
  ------------------
  Standard and TLM component specific database tailoring
  features support customization of database content to meet
  specific data center requirements.

  Data Dictionary
  ---------------
  A data dictionary, found in Appendix B, describes the
  content, meaning, and raw data source for each data element
  in the TLM component database files.

  Data Transformation
  -------------------
  Encoded values in tape library catalogs are transformed
  into easy-to-understand data elements, adding value to
  database file content.

  Protection Against Duplicate Data
  ---------------------------------
  Duplicate data is automatically detected and eliminated
  during daily processing.

o Interface Capabilities

  CA MICS database files are summarized in the same manner
  across all products.  Information from the TLM component
  files can be easily combined with other component files to
  compare and correlate tape data set and volume activity
  with workload and device activity created by other CA MICS
  components.
