Derby Users and Developers,
I have an application that has used Derby (with the Network Server) for years,
and overall I have
been extremely pleased. However, I ran into a problem when trying to upgrade
to 10.9.1.0.
I have three computing environments that I work in, which can be thought of a
development, test, and
production. For reasons not worth the trouble of explaining, these three
environments are slightly
different, but until the latest release of Derby I could make them appear to be
very similar by the
use of the Windows "subst" command, which associates a path with a drive
letter. For example, the
command "subst K: C:\SomeDir" makes the system appear to have a "K" drive,
which in reality is
simply mapped to the directory SomeDir on the C drive. All previous versions
of Derby handled
databases on this substituted K drive without any problems, but version
10.9.1.0 breaks on it. I
was able to get around this problem by setting up a virtual drive using a
different approach, so now
I have been able to upgrade Derby, but I wanted to point out the problem is
case others have
encountered it.
