Hi Giovanni,

Now, you can't install two perfSONAR instances on one Tomcat. The 
problem is configuration properties files -- different for various 
instances. Now, these files cannot be shared. There are a couple 
solutions of that problem, but they need some changes in perfSONAR.

So, for now, if you want to run multiple perfSONAR instances you have to 
install two Tomcat+Axis instances as well. But remember, that both 
Tomcats must work on different ports, for instance 8080 (the default 
one) and 8090. Database for LS and MA may be shared (if using eXist DB 
for MA, because for LS it's compulsory)

For suggestions how to do it, please contact Szymon 
(), because he did it for PIONIER MA and LS.
As far as I remember he wrote a wiki page about it, but I may be wrong.

The perfSONAR v.1.0 is our first release. Since it was released many 
changes have been done (some very important). You probably know that we 
work with SVN and all changes are commited on SVN server. When a 
developer wants to publish his work he does the "snapshot" of SVN 
repository. As snapshots are done by developers separately, so they may 
differ from each other. Although the snapshot for LS may contain java 
sources for all services, only LS classes are compiled and also 
configuration scripts for other services may be removed.

So, the snapshots are addressed for users who want to deploy the newest 
version of a service regarded by its developer as quite stable.

Since the last (and the first) release (v.1.0) there have been several 
changes, such as result codes, HTTP access for eXist database, new 
Message Handler, LSCleanup bugs were fixed, etc., etc.

So I'd suggest to use snapshot version for testing, especially for LS. I 
think we're very close to start the second release process.

Best regards

Maciej
