other files that i had installed.
I have proven to compress the directories of the data
base in zip and to thus accede to the data base. But
the data stored in the cache was not readen.
URL:
jdbc:derby:jar:(C:/Iva2005/com/aeat/iva2005/datos/CloudScape/Red.zip)Red
Driver: org.apache.derby.jdbc.EmbeddedDriver
I need group the files of the DB in order to erase and
actualize versions withot danger of erase files that
an crazy user can laid in.
¿there is an log of the files created by derby?
¿Can be grouped/compressed?
Very Thanks

Hi Juan -
I am not clear on what your needs are, there seems to be a couple of
issues and I will need more information to make a helpful response. Can
you respond to the following?:
a) what do you mean by: " ...distribute an DB (and actualization or
deinstallation)". You can copy the database directory tree to any new
location. The system needs to be shutdown when the copy is made.
b) In regards to:"i cant delete other files" what are the names of the
files you are attempting to delete? - how are you attempting the delete?
and what is the error/messages returned by the attempt? Is the database
shutdown when the delete is attempted?
c) In regards to "But the data stored in the cache was not readen."
derby provides no way to monitor the cache - how were you determining
what happened to the cache? If by 'readen' you mean 'written' (that is:
saved to disk) you will need to unjar the database first. When placed
in a jarfile the database is read-only so you will not be able to write
to the database. The database files will need to be unjarred to create
a full read-write system.
d) In regards to: "¿there is an log of the files created by derby?" No,
there is not list of filenames that are created by Derby. All the files
contained in the database directory tree are what is created - for more
info see the FAQ: section "What are the basic components of a
Derby/Cloudscape deployment?"

http://www-128.ibm.com/developerworks/db2/library/techarticle/dm-0408bradbury/
e) In regards to: "¿Can be grouped/compressed?" Derby can access a
database stored in a jarfile - such a database is read-only until it is
uncompressed.
