[kepler-dev] Kepler - bug related to user.home settings

[Michal Owsiak]

Hello Jianwu,

thanks for your suggestions, but I think this issue still remains. Maybe 
we have slightly different use-cases.

Use-case:

- I want to start multiple instances of Kepler at the same machine
- I want each of Kepler instances to be executed in separated HOME

I am using following scripts to achieve that:

(both scripts are executed inside $HOME/kepler_temp)

--- CUT multiple.sh ---
#!/bin/tcsh

mkdir $1
cd $1
setenv OLD_HOME $HOME
setenv HOME `pwd`
$OLD_HOME/kepler/kepler.sh -D"user.home"="$HOME"
--- CUT ---


--- CUT start_test.sh ---
#!/bin/tcsh

./multiple.sh 0 &
./multiple.sh 1 &
./multiple.sh 2 &
--- CUT ---

- Create directory kepler_temp in your $HOME
- put multiple.sh and start_test.sh inside $HOME/kepler_temp
- start ./start_test.sh

As you can see, only one Kepler instance is started.
