My DECmcc non-stop requirements are very strigent. My client would like to see MCC running on a two node VAXcluster. The display would be on a workstation. If the cluster processor fails, MCC would failover with no noticable effect on the display except for maybe some slighly longer response times. The most obvious way to acheive non-stop is the FTvax. This is my first choice; we are looking into ramifications. As for the cluster platform, I would think we would need to add failover capabilty to the MCC code and write a custom distributed PM that could maintain context during failover. Either of these is no easy task, but if we are to manage critical networks, the network manager cannot a point of potential failure. Any comment?

I can't offer anything but the obvious. Configure the appropriate
machines, find the difference in cost. If the development cost exceeds the
difference, you have your choice.
Please be cognizant of the life cycle cost of these changes. In a VAXft
solution, there are NO code maintenance costs. Given that an VAXft
solution is usually only 20% higher than a comparably configured
dual-host solution, I would go for the VAXft solution.

| 2393.2 | Go for FT!!! | WOTVAX::HATTOS | I think, Therefore I'm paid less | Mon Feb 24 1992 08:26 | 8 |
I have T1.2.4 running on a 410FT and have no problems at all, (except
those already known)
The FT solution would seem to be the best for this situation. In a
cluster config. you will go through a cluster transition if you lose a
node, which will cause your MCC display to hang for a while.
