You can unload and reload a database using system commands or VDBA.

At the command line, use the unloaddb and sql commands. For details, see the Command Reference Guide.

In VDBA, start by using the Generate unload.ing and reload.ing dialog. This dialog is invoked by selecting a database and choosing the Database menu, Generate Scripts, and Unloaddb. For the detailed steps, see VDBA online help.
