When running a mutually-aware setup do I need unique RCM's?

Hello,
I'm not sure I follow your question. You can only have one
RCM per each OpenSwitch instance.
In 15.0 they introduced what they call the "Concurrent
Coordination Module" feature:
http://infocenter.sybase.com/help/topic/com.sybase.help.openswitch_15.0.oswref/html/oswref/CHDHADFB.htm
Using this feature you could have two CM's connected to a
single OpenSwitch instance in case one of the CMs had a problem.
The RCM does not support this feature.
Thanks,
Neal

I think I found my answer. I wasn't sure if I needed a
separate RCM of each openswitch or if I could rely on the
same RCM to switchover replication in case of a failure on
the primary database. Looks like I need another RCM
according to the mannual.
