We have enabled cluster as per the manual and we see the cluster comes up and then there is a message every 3 minutes which indicates that the server is removed from cluster.
In our configuration we have two machines and each run 3 instances of integration servers svr1,svr2 and svr3. The corresponding svrs in each machine are clustered.

Try setting the node names to the hostnames/ip-addresses of the machines instead of logical names and make sure the machine running the repository server is able to “ping” those names.
Hi Jordy,
Thanks for the tip. I have done it. The repository server is running on one of the IS machines and has access to both. Still the problem exists.
Can you elaborate? Implied in this statement is that there are two machines, each running 3 IS instances, both machines using the same set of names:
Machine 1
svr1
svr2
svr3
Machine 2
svr1
svr2
svr3
And there is one repo server being used by all instances on both machines? The machine 1 instances are in a cluster and the machine 2 instances are in a different cluster? What are the cluster names?
I had the same problem got this one resolved. I increased the log level and found out that the
second server is unable to register connections with the first.
There is a problem with the ACL created automatically with the
remote servers. I changed it to use ACL
And this issue doesn’t arise anymore.

When you use Settings → Repository to define Repository Server Aliases, IS automatically creates remote server aliases as well. However, it creates them using the Repository Server Alias as the “Host Name or IP Address”.
As of IS 6.5 SP2, the ACL settings for this remote server alias were correct. However, the hostname/IP address property had to be changed to an actual hostname or IP address rather than the repo server alias name.
