Hi Sridhar,
You can specify derby.system.home on the java command line when you
bring up your server or embedded application. E.g.:
java -Dderby.system.home=/apps/myDerbyApps ...
Hope this helps,

thanks, rick. But, as per Scope of Derby properties in Derby property
reference,
I can not put that property in derby.properties. Scope of Derby
properties Please tell me where to give this property.
"The /derby.properties/ file is an optional file that can be created
to set properties at the system level when the Derby driver is loaded.
Derby looks for this file in the directory defined by the
/derby.system.home/ property. Any property except /derby.system.home/
can be set by including it in the /derby.properties/ file."
the second problem is completed it is working now. earlier it did not
work, i gave the correct syntax only.

Hi Rick Hillegas,
Thank you very much for your reply. I just want some more
information regarding derby.
I want to move this database directory from my home directory.
I use windows xp professional. My c drive is not having enough
space. So, it is not good to put the database in my home
directory. Moreover, When I have to install I will format my c
drive. So, I need a way to tell derby to store databases in
some other location.
You can use the derby.system.home system property to tell Derby
where to put your databases. For more information, please see the
following section of the Derby Developer's Guide:
http://db.apache.org/derby/docs/10.5/devguide/devguide-single.html#cdevdvlp27610
I am having 2 more problems with derby is that I am unable to
start derby network server using derbynet.jar and
derbyrun.jar. At present, What is working is thru
setNetworkServerCP,startNetworkServer and stopNetworkServer.
Can you or any body help me in this issues?
What command are you using to bring up the server and what error
are you seeing?
Thanks,
-Rick
Regards,
Sridhar

Hi Sridhar,
There is no Derby command for deleting a database. A
database is
simply a directory of files--if you want to delete it, you just
use operating system commands to remove the directory. In your
case, you would be deleting the sampleDB directory.
You also asked a question about schemas, which I didn't
understand. Forgive me if I am talking past your question:
You can
use the CREATE SCHEMA command to create schemas other than
sys and
app. If you use an authentication mechanism to control who logs
into the database and if you turn on fine-grained SQL access
checks, you can control who is able to read and write the
data in
the schema which you created. For more information, you may
want
to consult the security documentation in the Derby Developer's
guide:
http://db.apache.org/derby/docs/10.5/devguide/devguide-single.html#cdevcsecuree
Hope this helps,

Hi,
I hava a database, let us call it, sampleDB.
I connect to it using ij through the below command.
connect
'jdbc:derby://localhost:1527/sampleDB;create=false';
I want to remove sampleDB. So that nobody can connect to it
even using sys schema.
This database is in different schema other than sys and
app.
I am unable to find in docs and google on deleting
derby database.
Can I delete it from my own schema from which I usually
connect to this database?
what is the command for deleting database?
how to know the tables / data in the database?
bye
