1.2.2 Features

Major features of the VTS component are discussed below:

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 10.2, VTS User Exits.

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

  Database Tailoring
  ------------------
  Standard and VTS 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 VTS component database files.

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

  Computed Data Elements
  ----------------------
  Numerous VTS component computed data elements are added to
  the VTS component database files, providing value to the
  component beyond the basic metrics found in the raw data.
  Computed data element derivation formulas use statistically
  accurate techniques that avoid, where possible, problems
  such as representing "averages of averages" in summarized
  data views.

  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 VTS component
  files can be easily combined with other component files to
  compare and correlate virtual tape drive and controller
  activity with workload and device activity monitored by
  other CA MICS components.
