Hi Tino,
You can use the Sequoia mailing list for sequoia related questions. The
community mailing list is more targeted to announcements.
I try to start the controler the first time but it fails with an
Exception from jgroups (see full_cluster.log):
2008-05-15 09:28:17,107 ERROR controller.xml.DatabasesParser The

Anyone an Hint, what could be wrong?
I had that problem once with virtual machines. This is a JGroups
configuration problem.
You should alter the JGroups configuration file (likely to be
config/sequencer.xml) to force IP addresses and port numbers. I am not
sure where this 192.168.5.1 comes from, it might be a default value.
Don't hesitate to ask support on the JGroups mailing list if you still
have troubles.
Test runs in 3 VMs, Controller use default property files:
System 1 (Controller):
IP: 192.168.80.130
OS: Ubuntu 8.04
DB: MySql 5.0.51a
Java: 1.6.0_06-b02
System 2 (DB-Backend 1):
IP: 192.168.80.131
OS: Ubuntu 8.04
DB: MySql 5.0.51a
System 2 (DB-Backend 2):
IP: 192.168.80.132
OS: Ubuntu 8.04
DB: MySql 5.0.51a
Note that if you have a single controller, you do not need group
communications and you can remove the Distribution element from your
configuration file.
Thanks for your feedback,
Emmanuel
