TurboIMAGE DBchange/V 

DBchange/V is the interactive utility that allows dynamic restructuring
and capacity expansion of a TurboIMAGE database.  Database changes are
input using a menu format and executed either on-line or in batch mode.

DBchange/V allows easy screen access and input of database restructuring
requests for TurboIMAGE databases.  Because multiple restructuring
changes can be requested during one DBchange/V session, there is no need
to run separate programs for each restructure feature.  DBchange/V allows
you to review multiple change requests before actual updates are
processed.

DBchange/V provides the database administrator with an important tool to
aid in the use and support of TurboIMAGE databases.  Additional benefits
include ease of use and batch capabilities.  DBchange/V also includes the
DICTDBA, DICTDBU, and DICTDBL database utilities, which facilitate the
control, maintenance, and restructuring of TurboIMAGE databases.

Key DBchange/V Features 

Key DBchange features include:

   *   Interactive forms access allows flexible database manipulation.

   *   Two-stage update process allows input and review of changes before
       actual update.

   *   Multiple changes can be made to the same database in one
       DBchange/V session.

   *   Database restructure requests are input and stored in a change
       file.  DBchange/V uses the change file to process database
       modifications.

   *   Modifications can be processed immediately or scheduled for later
       batch processing.

   *   TurboIMAGE database modifications can be made in real-time,
       without requiring a DBUNLOAD and DBLOAD.

   *   On-line help facility provides information about commands and
       parameter requirements.

   *   The Root File is checked for path information inconsistencies,
       allowing DBchange/V the option to make corrections.

Interactive DBchange/V commands allow the user to:

   *   Rename a database
   *   Copy a database
   *   Change database security
   *   Restructure a database
   *   Print schema
   *   Change set capacity and blocking factors

All TurboIMAGE and MPE file security and capacities are respected.
DBchange/V verifies that the user has proper access before it allows
changes.

DICTDBA 

DICTDBA checks the integrity of synonym chains and identifies broken
chains.  It generates reports on synonyms and chains for master sets and
chain statistics for detail sets.

DICTDBU 

DICTDBU unloads the contents of an existing TurboIMAGE database.  It can
unload the database chained to either a disc or tape file, thus
organizing the records for efficient chained access.  DICTDBU also
provides the capability to unload only selected data sets.

DICTDBL 

DICTDBL loads the stored contents of a TurboIMAGE database.  It
simplifies and speeds up the database load function when only a few sets
must be loaded.
