Re: [kepler-users] Multiple users run multiple workflows on shared computer
Hi,
We have similar case, as you have and but we are running Kepler 2.3.
Please find below what is our procedure, that works for our
applications/users.
I'm convinced others might give you better way to do it.
1. We are using central installation of the Kepler on the machine
2. We generate unique value for location of each instance of Kepler
running for each user
export HOME=$USER_HOME/kepler_tmp/${UNIQUE_VALUE}
export KEPLER_NEW_HOME=${HOME}/${KEPLER_SHADOW_DIR_NAME}
3. We do symbolic links to the central installation in that temporary
directory
4. We change configuration files to prevent mulitple kepler instances
from using the same hsql DB
(every single instance of kepler will be using separated hsql database
file)
(/common-2.3.0/resources/configurations/configuration.xml)
(/core-2.3.0/resources/configurations/configuration.xml )
5. We replace all necessary jars with provided kepler.jar with a patch
(there was one line needed to be patched in 2.3, I think it is not the
case for 2.4, but I'm not sure)
6. We run each instance of Kepler like that:
java -Duser.home=${HOME} -classpath
${KEPLER_NEW_HOME}/build-area/lib/ant.jar:${KEPLER_NEW_HOME}/kepler.jar
org.kepler.build.runner.Kepler -runwf -nogui ${PARAMETERS} -dir_path
${CURRENT_DIR}/ -nocache ${CURRENT_DIR}/${WORKFLOW_LOCATION}
${CURRENT_DIR}/kepler.log
I hope this will help you.
regards
Marcin Plociennik

Hi,
We are developing a Kepler workflow for users that will run on a shared
computer for many hours/days optimizing models of experimental data. Our
requirement is for multiple users to run kepler workflows on a shared machine
and those users run multiple workflows. We have made the changes on this
webpage, https://kepler-project.org/developers/reference/accessing-hsql, so
that kepler will run for multiple users, but now each user can only run one
workflow at a time. Much time has been invested in developing a complicated
workflow and we did not find this problem until two developers started running
on the shared machine. It is not mentioned in the user's manual.
Is there some way to turn off the HSQL database? Will this problem be fixed in
a future release? Is there some workaround?

Re: [kepler-users] Question about the Display actor and the composite class
Dear Daniel, thanks it works with 2.4, while the problem exist in 2.3, so it seams there are some bug fixes applied. regards Marcin W dniu 2013-04-17 20:41, Daniel Crawl pisze: Hi Marcin, I saw a similar exception in Kepler 2.3 by putting a Display actor inside a MultiInstanceComposite.

That way as you know I can use that composite in many place, and the changes would be applied to all the instances. 5. I can use that actor in the workflows , I can edit and add there inside most of the actors including other composite, and it works 6.
