Administrator Command Reference Manual
Command Details : Detailed Descriptions of Commands : DELETE (Project definition)
DELETE (Project definition)
Function:
Deletes elements from the project.
Notes on Deleted Files
When a database is deleted, its file is renamed by addition of the suffix .deleted. The renamed file is actually deleted on the next SAVEWORK or module switch, once the change has been saved in the system or global database.
This arrangement allows database files to be recovered after a crash, by the AVEVA E3D™ exit handler. However, if the exit handler cannot be invoked (for example, due to a loss of power) then the files with the .deleted suffix can be restored manually, to make the project directory consistent with the system or global database.
Description:
The DELETE command can be used to delete Admin elements.
The DELETE command cannot be abbreviated. This helps protect against accidental deletion. To avoid the risk of database corruption, all deletion of DBs (i.e. the files inside the Project Directory) must be done from the ADMIN module and not by using operating system utilities or commands.
Notes on Global Projects:
You can only delete Teams, Databases, Locations and Groups at the Hub.
Offline locations:
When a location is deleted, the system administrator must make sure that the system database for that location is deleted from all other locations.
Refer to Running Global Projects for further information about Deleting Databases and Using Extracts from a Global project.
