Re: Intelligent IP sprayer or round robin

It sounds like you're looking for a load balancer; many of those now have
the capability to detect down services & not route to them. My former
employer used the Big IP boxes from F5: http://www.f5.com/products/big-ip/
You can do more than just load balancing; you can also offload SSL to the
appliance and do other network/traffic management tricks.

If you're looking for a purely i-based solution, I'm not sure. WebSphere
Network Deployment might work if your apps run on WAS.

I am looking for an intelligent IP sprayer or round robin configuration. A
simple ping is NOT sufficient. For example, if I have a location like
sametime.corp.dekko.com and I have two servers sametime01.corp.dekko.com
and sametime02.corp.dekko.com I want it to route it to one of these that
is actually working. Now, just because I can ping
sametime01.corp.dekko.com and it comes back successfully doesn't mean the
service is working. The ping will be returned by the OS. The service may
be a job running under the subsystem assigned to the a particular Domino
server.

Is there some way to do this?

I also don't want to go from saying:
"We only have one sametime server. If that is down we're toast."
to saying:
"We only have one intelligent IP sprayer. If that is down we're toast."
IOW, I don't want to just trickle up the single point of failure.
