reduced. You must first define a new volume and extend the database if the
number in that column is smaller than the size of the volume you wish to delete.
Use the reduce db command to reduce the database size. Once the database is
reduced in size, the desired volume can be deleted. Example 5-14 shows the
procedure.

We see we have plenty of space for reduction, as the default database volume is
only 16 MB in size. We have one other mirrored volume of 1 GB, so there is
enough space to reduce the size or the database. The second query db shows
that the maximum extension is now 16 MB, since the default volume has not yet
been deleted.
Use the query dbvolume command to see the full name of the file. You can now
delete the default database volume using the delete dbvolume command, as
shown in Example 5-15.
