Oracle have a kernel patching tool called Ksplice that they acquired

Given the high-availability mindset for VMS users, I wonder if VSI ever
considered creating something similar for VMS ?

What about process migration?

 Like Galaxy on Alpha?

I thought Galaxy was multiple logical systems on one physical system.
DEC answer to IBM LPAR.
I am thinking about a scenario like:
* cluster with node A and B
* critical process P that for whatever reason does not work
   running concurrent on multiple nodes runs on A
* node A needs to be taken down for some reason
* so VMS on node A and B does some magic and migrate P from A to B
   transparent to users (obviously require a cluster IP address or
   load balancer)

There is vMotion for virtual machines on ESXi, but that's not exactly the same.

I know about that.
Not exactly the same but similar concept.
