Hi Dave,
Thanks for pointing this problem out. I simply forget to provide an AMQ
patch to fix it; this is now done:
http://issues.apache.org/activemq/browse/AMQ-746.
Also, this feature is broken in 1.1. Basically, SharedLib and
FileKeystoreManager do not properly resolve their resources and, as a
consequence, the server simply shuts down.
Thanks,
Gianny

BTW, I think additional fixes are required in 1.1.1 before claiming
support for multiple concurrent server instances from a single
installation..
Awhile back I was able to start the server using an external var
directory (via -Dorg.apache.geronimo.server.dir). After changing all
the ports and trying to start a second instance from the default
location, I encountered a startup exception regarding the activemq
transaction journal. Suspect code changes are needed to relocate the
journal to a location outside the installation directory.
Thanks

---------------------------------------
Currently working on scripts as discussed at
http://www.mail-archive.com/dev@geronimo.apache.org/msg22807.html .
Have made changes but they need to be tested on windows, cygwin and
unix, so looks like this is going to be for 1.1.1 .
Multiple servers sharing the same repo and config store

Many people have talked on and off about how to set up multiple
servers sharing the same repository and config-store, but we
haven't arrived at an agreed on way to do it. We have a
prospective customer for this feature (Vincent Massol with Cargo)
so I'd like to move beyond thinking about it in my head, discuss
it, and have someone implement it. I believe any implementation
will be more or less trivial, the hard part is figuring out what to
do.
I've only thought of ways to extend what we have now, rather than
restructure anything or add big new capabilities. If someone sees
a better way, please speak up.
So, we have a ServerInfo gbean that knows where geronimo is located
and can resolve absolute locations for other components. Then we
have things like the repository and config store gbeans that
typically are "located" outside the var dir and things like the
logging framework, local attribute manager, derby, and tomcat,
that typically keep stuff in the var directory.
All or most of these start with the first configuration loaded so
they can't have any attributes overridden by config.xml: in fact
this file is read by one of the gbeans that we need to "relocate".
I've thought of two related solutions. Both of them involve giving
ServerInfo knowledge of another path and another resolve method.
One would be something like "resolveVar" and would normally resolve
to geronimo_home/var. This would involve all the gbeans currently
looking inside var having the "var" trimmed off the front of their
paths and using the new resolveVar method. In this case we'd have
different servers represented as e.g.
var1
var2
var3
...
The other would give ServerInfo something like resolveServer which
would normally resolve to geronimo_home. The gbeans looking inside
var would keep their current paths and just call the new resolve
method instead of the old one. In this case we'd have servers like
var
server1/var
server2/var
...
In either case I think starting geronimo with a command line
argument pointing to the var directory is the only way to specify
which server you want to run; the default would presumably be as
now "var".
Several people have suggested putting an additional config-store
into var for "private" use by a particular server. At the moment I
think that providing a different config-store class that uses the
new resolve method on server info would be the best way to do this.
I'm not attached to these ideas but this is as far as my thinking
has gone. Please comment.
thanks
