I had read the requirements and checked with our netadmins: both controllers
are on the same subnet, connected to a switch and the admins say that nothing
should block the traffic, even in multicast (I specifically asked for that).
The controllers are hosted on 2 windows box (1 win2k and 1 XP) with no
firewall. Their network config seems pretty standard to me.
I am at loss...
I saw that appia.xml has 6 templates of channel config. The default one is
activated (tcp_sequencer). Is another channel config more likely to succeed or
is more advisable?

Thanks,
When I turn off JGroups debug logs, it looks like both controllers try to
exchange a message and then just hang (if I kill one of them, the other one
will detect it resume action - i.e. go to "listening mode" - sorry my wording
is not accurate). You can see this in the attached logs.
I also tried to swich to appia. Both controllers wait in "ready, listening to
requests" mode. They do not reach the "Checking virtual database configuration"
stage. So I guess they do not see each other.
For both JGroups and Appia, I used the default config files provided with
Sequoia 2.10.2. From the docs, I had gotten the idea that they were good to
use. Did I miss something? Are some settings to be changed?
This could be something in your network configuration. How are your machines
connected? The machines are just connected to a switch, or there is a WAN or a
firewall? Do you have multicast enabled between the controllers?
The default setting are for a fully connected cluster with multicast enabled.
You have several tips in the Sequoia installation guide ("Network Requirements"
and "controller group communication configuration files" sections).
If you still have problems on using Sequoia with Appia, please don't hesitate
to send your feedback to the Appia mailing list.
