Thanks, Jesus. Since you and James are discussing it, I'll make some
comments about what's unclear to me from reading this page, as a novice:
-What is the path of server.xml?
-How do we "modify the objects that sessions of DSpace uses"?
The structure of this page
http://wiki.dspace.org/index.php//HOWTO_Clustering
is also unclear to me--it seems like a list of options that were tried. It
would be preferable to me (as a novice), to have a recommendation at the
top, clearly marked as such, followed by categorized alternatives. (For
instance, how does Terracotta relate to Tomcat)?
Scalability is definitely important, so and I hope that those who understand
it will continue improving these instructions, and provide some scalability
metrics as well at the stub
http://wiki.dspace.org/index.php/ScalabilityMetrics
Thanks again for your improvements!
