Hi List, Garry just send me an excellent solution to the problem I mentioned with regards to Alarm Notifier fault tolerance and he allowed me to share it. The beauty of his solution is, that it uses an attribute on the model which has the alarm instead of checking files of attributes on the vnm model. The latter could have some performance impact, especially if a lot of alarms are generated in a short period of time. Garry's solution just uses the SANM functionality to pass any attribute of the alarmed model at almost no cost.

On the primary if Precedence is 10 (primary running) it sends the message, if the precedence is 20 it stops email processing On the Secondary its the other way around - 20 = send , 10 do not send So if the Primary server goes down completeley then precedence is now 20 so secondary sends. If Spectroserver stops on Primary the precedence is now 20 so secondary sends If both are running but we have a comms error so they can;t see each other then both send (can't see a way around this but its not a common issue) Here is a line from the SetScript on the primary, hope it all flows from there if [ "$SANM_0X12C0A" = "20" ] then echo "SS Secondary is running" echo "Precedence = $SANM_0X12C0A" exit 0 fi On Fri, Jul 16, 2010 at 7:16 PM, Henrichs, Joern <[email protected]<mailto:[email protected]>> wrote: Hi Jim, we are running Notifiers only on the Main Location Server landscape for ease of administration. The Notifier itself is fault tolerant. If the primary SpectroSERVER application crashes it reconnects to the secondary. But be aware, that if the machine dies - you need to start the Notifiers manually on the secondary server. We have been thinking from time to time how we could run the same Notifiers on both primary and secondary and process alarms depending on the SpectroSERVER status, but we did not find a good way yet.

Juni 2010 16:27 An: spectrum Betreff: [spectrum] HA/FO SANM Hello fellow Spectrum admins- We're running Spectrum 9.1.3 on four landscapes, each with a primary and a failover server, along with another landscape pair acting as a trap director only. I've looked through the SANM documentation and the Wiki, but it's not clear to me how best to set up SANM in this environment to be fault-tolerant. It seems like we have two options: 1. Run SANM on every server, give each notifier process a unique name, and restrict each notifier to alarms from that server via policy 2. Run SANM on just one landscape pair and have it manage alarms for all landscapes I'm not certain that method 1 is necessary, or even possible; method 2 may be sufficient, since the odds of losing both machines in the same landscape seem quite small. Is there another option I haven't considered? How are y'all doing this?
