C.- In the prove i erase the directories "log" and
"tmp", and sometimes the files "db.lck" and
"vssver.scc" too.
B.- Users can be telled for not store anything in
derby directories. Trully would choose another
location. But we want not to be this posibility. O
that an user can erase 2 or 3 files and damage the DB
without erase totally. The user will call us for it,
and we not understhood it.
Whith a lot of users is better an only file for all
DB.
¿If i make an new version is better erase all data
bases and copy the new or copy only changes?
I think that copy only changes is dangerous.
Thanks.

By "delete all the data base", I assume you mean
delete the directory
that was created when the database was created with
the "create=true"
flag. For example, given this connection URL:
connect 'jdbc:derby:test;create=true'
Derby creates a "test" directory with all the Derby
database files.
Deleting the database is as simple as removing that
"test" directory.
Could you tell users to not store their own files
under the Derby
database directory? that it is only intended for use
by the Derby
datbase itself? Instead they should choose another
location.

When you say that you erase the cache files, which
specific files are
you removing?

Please don't worry -- it might just mean that we need
to ask more
questions to make sure we understand what you mean.
