Hi all,
I wanted to deploy my App with Derby in USB drive but I'm not sure
is there any restrictions or not ? or problems ?
Thanks
Hi,
I have tried copying the jre(for the operating system of the machine
into which you will plug in the USB drive),
derby.jar, derbytools.jar into a USB and tried to create a database,
create tables, insert data etc, and it worked
fine for me.
I noticed it was a bit slow, possible because it is doing IO to the
USB disk.
I used my creative muvo mp3 player which also doubles up as USB.
I haven't tried any serious testing though.
I just did it as a casual exercise.

I did something a little bit more interesting. I had two machines one
running
solaris and another linux. I copied derby.jar, derbytools.jar and the
jre's for both the
OS in my USB. I created the database and the tables in one OS, shutdown
the database
and tried opening it in another OS. I tried it both ways
create in solaris, open in linux
create in linux, open solaris.
It worked fine in this case.
As mentioned earlier I did not do any serious testing.
While doing this you just have to remember to boot the database
each time with the appropriate jre inside the USB.
I thought it would be interesting if I could find a mechanism by which I
could choose the correct jre automatically, but never got to doing that.
Thought this information might be useful to you,
Narayanan
