[jira] Commented: (GERONIMO-1638) Multiple servers sharing the same
repo and config store
[ http://issues.apache.org/jira/browse/GERONIMO-1638?page=comments#action_12415496 ]
John Sisson commented on GERONIMO-1638:
---------------------------------------
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 .

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
