[Dspace-general] Multiple instances of DSpace?

Hi,

(not quite sure which list this originated from, so apologies for the
cross posting)

I don't think it's that difficult.  You need a separate database for
each instance.  e.g.

dspace-1
dspace-2
dspace-3

and a separate config for each instance

dspace-1.cfg
dspace-2.cfg
dspace-3.cfg

and separate install directories:

/srv/dspace-1
/srv/dspace-2
/srv/dspace-3

now run the fresh_install target of ant with each of the relevant config
files:

ant -Dconfig=/path/to/dspace-x.cfg fresh_install

this should put all the code in /srv/dspace-x and the dspace.war and
dspace-oai.war in the build directory, and the data in the dspace-x
database.

Now just stick the war files in the [tomcat]/webapps directory as, for
example, dspace-x.war and dspace-x-oai.war

The thing to be careful of, if building from the same source tree is
that you empty [dspace-source]/build in between each fresh_install (or
update), else you might have problems with the web.xml file.

Anyway, do this for your 3 instances, so you should have 3 separate
dspace-x.war and dspace-x-oai.war files in your webapps directory.
Restart tomcat and you should be able to get them at:

http://my.dspace.edu:8080/dspace-x

Since they are now effectively entirely separate applications, there
shouldn't be any cross over between config or data if the original
configurations for each one are correct.

I tend to do this with different source trees, as I mostly run different
versions in parallel, and I have never had any problems; let me know if
there are any gotchas that I've missed.
