Hi Theo, You're right. I managed to install the 3 AR Servers by fooling the installer as you said. But when I configure them in a server group and start the servers one after the other, the service wouldn't start.
It complains armonitor.conf file cannot be found. It is looking for a folder in the Load balancer name in /etc/arsystem !

The only way you will be able to do this is to fool Remedy into thinking each instance is running on a diferent hostname by: 1) Aliasing the 3 different server names in the host file. 2) Setting the HOSTNAME variable before installing / starting each copy of ARSystem. This may or may not work, is a bit dangerous and can NOT be recommended for a production environment.

AR Server service refuses to start. It complains armonitor.conf file cannot be found. Each AR Server (arsystem startup script) is looking for /etc/arsystem/d1/armonitor.conf !! d1 is the Load balancer = Server-Name in ar.conf. I cannot use 1 armonitor.conf for 3 AR Servers. Can I? The server-connect-name is referred inside the armonitor.conf which is different for the 3 AR Servers! I find this architecture/requirement equally weird. It was decided by the client. They want 3 AR Servers on one physical server in a server group. I'm trying to squeeze Remedy into it now.

Our client gave us one physical server with 3 virtual IP Addresses. And asked us to install AR Server on each of the virtual IP Addresses, all on same port. I guess I'm not able to use iptables restriction because I want to use the other IPs too , but for a second and third instance of AR Server. I'll write back to them stating that the current version of AR Server doesn't support this. Perhaps I should raise an RFE.

I looked through all the ar.conf parameters and flags supported by arserverd and it does not look like there is a way to tell arserverd to listed on a specific IP. You could use iptables to restrict access on those other IP addresses since you are on linux.

They will bind to a TCP port if one is specified (and/or use portmapper if that is set). If you are not connecting to the AR Server one item to check is the /etc/hosts file.
