[kepler-users] Simultaneous Workflow runnings

[Christopher Brooks]

Hi Josep,
I'm just returning from vacation and catching up on my email, so
I'm not sure if this was handled or not.

There is a problem with running multiple versions of Kepler because
of the hsqldb database.  For details, see
http://bugzilla.ecoinformatics.org/show_bug.cgi?id=2315

When you started up the second GUI, did you see a stack trace?

I believe that in Kepler-1.0.0, various efforts were made to create
shell scripts that would run commands without the GUI and without
hsqldb, thus avoiding this issue.
There are some instructions at
https://dev.kepler-project.org/developers/reference/executing-kepler-from-the-command-line
but I could not run Kepler-1.0.0 from the command line twice
and avoid the bug.

Another trick would be to run each instances of Kepler from a separate
user account.

In the devel tree, the build system is being reworked and some
of these issues are being addressed.  You could take a look at
http://mercury.nceas.ucsb.edu/kepler/pipermail/kepler-dev/2009-February/013822.html
for more information.
