Dear Thomas,
Thanks for your inputs.
I am not much familiar with the APIs.
Let me tell you how I am proceeding:
1. I have copied the database folder "hatterastc" from the server to
my PC.(This database is embedded in 1 application.)
2. I get the error when I execute the following command:
ij> connect 'jdbc:derby:hatterastc';
ERROR 08004: Connection refused : Invalid authentication.
I suppose the CALL command can be executed only after connecting to a
database.
I have a Windows System and using the ij prompt from the cmd.
Please let me know how to reset the password from the ij prompt.
Hi Sonny,
Can you please specify which version of Derby you are using? I.e., is it
10.1 or maybe 10.5?
(10.0 was released in 2004, 10.6 in 2010)
Now, resetting the password isn't supposed to be easy, as it would
defeat the purpose of authentication.
Except from connecting as the system user (which may very well be the
user you have forgotten the credentials for), I'm not aware of any way
to reset the password for a user for which you don't have the password.
Unless the system security has been configured using derby.properties
(which isn't recommended because it is a weak mechanism), I don't know
how to help.

Thanks again.

login in with your data base owner account you can reset the
password of a user
by calling
SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY('derby.user.<username>' with
an empty password as the second parameter passed. Assuming you are
using the
builtin authentication provider. With the same stored procedure
you can also
create new users. (see reference guie on page 327 for details on
this system
built-in stored procedure)
To your second question: Yes, to clone a database you can just
copy the folder.
