perfSONAR User Q&A and Other Discussion

Hi Luuk,

There are two choices where you can set the LD_LIBRARY_PATH.

You only have to do it in one of them.

1) In the profile of the account used to run tomcat. This tomcat is the 
one used for java services. You can do this by adding the 
LD_LIBRARY_PATH declaration in the .bash_profile file.

2) Editing the tomcat start up script. You can declare the 
LD_LIBRARY_PATH at the beginning of the script. Please note that we 
haven't tested this approach so we can't be sure where it should be 
added and if it works.


We have explained where to set the LD_LIBRARY_PATH in the the 
requirements section of the 2.0 manual (right at the beginning. please 
see here: 
http://wiki.perfsonar.net/jra1-wiki/index.php/PerfSONAR_v2.0#Requirements). 
It says that you have to set it in your profile. By profile, we assumed 
that it is understood as setting it in the .bash_profile  file available 
in the home directory. If you think we need to add this to the manual, 
we are certainly happy to do this.
