Delete

There are times when you might need to delete a database. Here are some examples of times when deleting a database is recommended:

The database was a simulation database that you no longer want to have on the system.
The control strategy that the database defines is no longer being utilized due to plant reorganization or other reasons.
The database is no longer usable due to internal problems and cannot be repaired and you have already restored a good backup.
You have a backup of an old (that is, no longer used) database on the system.

Deleting a database removes the data files (including all configuration information) from the computer's hard drive. The files are deleted from the \\DeltaV\DVData\Databases\DatabaseName folder (where DatabaseName is the folder name of the database you are deleting). Once the database is deleted, the DeltaV nodes (workstations and controllers) that are defined in that database are no longer recognized.

Note

You must be logged on as the Windows user Administrator to delete a database.

The delete action automatically deregisters the database from the DeltaV system. The other workstations are no longer able to access that database.

If, after deleting a database, you continue to see the database name as a choice in your DeltaV Explorer (or in the Set Active Database tool), then you need to deregister the database manually. You manually deregister a database with the Register Database tool.
