Do I need two licenses to run Fail-over Mode on one box? We have a server running 24x7 as a service. It runs literally 24x7. The service crashes about once a week or so but we can’t seem to find a pattern or underlying cause. I will be looking into this more shortly. However I saw in the documentation that there is a feature called Fail-over Mode. Due to architectural reasons we cannot use another server. But I would still like to use the feature and I read in the help file a basic blurb that footnoted for FOM the standby service can be running on the same box as the master. I couldn’t get a clear picture on how to set it up though.

Would I need a second license or can I run two instances of the same install, one in master mode and the other in standby? If I can run two instances could you elaborate on how to set it up?

Thanks for any information you can provide.

You cannot actually run both master and standby schedulers on the same computer. They have to be physically on 2 different computers (or 2 virtual servers with 2 different IP addresses).

Regarding the weekly crashes try scheduling an automated service restart every night or every few days. You would need to make a batch file like
NET STOP "24x7 Scheduler"
NET START "24x7 Scheduler"
and schedule it to run as often as required.

I read in the help file that you could under [About Fail-over Mode]. It says, “Optionally you can run both Master and Standby Schedulers on the same machine. This secures continued processing in case of the Master Scheduler failure”. I hope that it can because it would be quite helpful.

Thanks for the idea. I actually had thought of that too. I got mixed responses on the team but I am planning on asking for mgr permission to set it up to see if it helps. In the past, with other services I’ve had sporadically crash, I have had them stopped/restarted each night and it greatly lessened the occurrence of crashes.

Thanks for the feedback. I appreciate it.

Yes, that is possible if you don't run them as a service. The same service name is used for both modes.

Ooh. That is a little silly. Darn. Thanks for the input. I guess I will have to see if we see any inprovement from stopping/starting the service each night. Thanks again. I appreciate it.
