Export Data

One function of the utility vovdb_util is to export the database into jobs data files. The exported files are saved in the vnc.swd/data/dump directory.

To execute the utility, first set up the CLI:
% vovproject enable vnc


vovdb_util: Usage Message
  Utilities for use with the VOV database.


  help         -- Shows help information.
  backup <dest>
               -- Backs up the VOV database to the specified destination.
                  This command must be run on the same machine as the
                  database.  If the destination exists it must be empty.
                  The database must also be running.
  clearcfg [-noconfirm]
               -- Resets the VOV database configuration to the initial,
                  unconfigured state.  Pass -noconfirm to skip confirmation.
  configure [-v] [-reset] [-noconfirm] <host> <root> [<port>]
               -- Sets the host, root data path, and port for the VOV
                  database. Pass -reset to overwrite existing settings.
                  Pass -noconfirm to skip confirmation.
  showcfg      -- Prints out current VOV database configuration.
  startdb      -- Starts the VOV database.  Will restart a running database.
  status       -- Prints current VOV database status.
  stopdb       -- Stops the VOV database.
  upgrade [-noconfirm] [-noclean]
               -- Upgrades the VOV database to use the newest version of the
                  PostgreSQL engine.  There must be enough disk space for a
                  temporary copy of the database files.  The database will be
                  offline during the upgrade.  Pass -noconfirm to skip
                  confirmation, -noclean to not delete temporary files if the
                  upgrade fails.

    The following commands are only supported for NetworkComputer and

  dump [-pre201509] [-start <YYYYMMDD>] [-end <YYYYMMDD>]
               -- Generate data files, optionally limited to the start and
                  end times specified.  Pass -pre201509 to dump the database
                  that was used prior to upgrade to 2015.09 (or beyond.)

  trim <YYYYMMDD>
               -- Deletes data prior to the given date.

  -v           -- Increase verbosity.

Database Export

Database export is done using the vovdb_util dump command. Pass the optional -start YYYYMMDD and -stop YYYYMMDD to restrict the dump to after the specified start date and before the specified end date.

Dump Pre-2015.09 Databases

If updating Accelerator from a version prior to 2015.09, it is possible to pass the -pre201509 option to vovdb_util dump to generate data files from the old database. This can be used to save old data if the original data files are no longer present.

Exported Jobs Directory

The vnc.swd/data/dump/jobs directory contains the exported jobs data. The dumped data files can be loaded into a new database using the vovsql_load_jobs utility.
