Sorry – I see Christian already answered this. No it isn’t a hoax – it is on the list of features to test with the 9.2 Beta. You should always trust in whatever Jerome or Kathy are presenting! :o)

But I remember clearly having seen this on the official SPETRUM roadmap presented by Kathy Hickey at a user meeting in Cologne. Mysteriuosly enough, I don't think it is too difficult to implement such a key feature - alarms are stored in the SSdb; it shouldn't be too hard to periodically sync a part of this database to a hot-standby instance (that is really running and not waiting for the primary to get lost and THEN start the local database!). We are also looking forward to having this, since a real redundancy is not just gapless monitoring from my point of view. Especially having a Netcool-like system on top, we've been experiencing very strange behaviours in cases of SS failovers, from total alarm loss to double alarms being shown on the non-SPECTRUM-console. As far as OneClick is concerned, docs talk about a load balancer based FT environment - which is no option for us ;-) I've built two identical servers that sync their customized xml files as well as PCause and Event-Files at night, so that each user can connect to the so-called "backup machine" when our primary OC server is in maintenance with the benefit of having to customize only one machine, not two. One might also think of a round robin DNS RR that points to two physical machines alternatingly. What I don't know is whether OC's Tomcat can deal with the machine's hostname and the hostname provided in the URL being different. What confused me though was that you wrote you have the same alarms on the secondary SS in case of a switchover. Did you mean you have identical alarms on primary and secondary SS, i.e. also in terms of date and time etc.?

All servers hold and generate their own alarms, resulting in an Ack, Status and Troubleshooter loss when FT failover occurs, not to mention unrealistic alarm creation date and time. Either implement a tool on top that handles that (some event correlation solution like Netcool etc.) or wait for 9.2 that is said to be scheduled around May or June this year. I've been told that an FT alarm sync feature will be implemented in this version. Something we've been waiting for since the 1990's!

I'm experiencing the same problems and I'm running 9.1 H09. Have you tried to adjust the SpectroServer polling interval in the OneClick Administration page? Besides the problem mentioned I also have another issue related to FT. When failing over from primary SS I still have the same alarms on the secondary SS, but the alarms lose their Trouble Ticket Id, and acknowledge information. Anyone else experiencing this?

My issue is that my landscape does not respond, then the global alarms do not respond after which it tries the FT system. It then proceed to swop back and forth between the FT and primary servers. At this time oneclick is unavailable you cannot logon as it says that there is no spectroserver available. What causes the landscape to not respond? And how do I resolve this. When in this state I reboot both spectrum server.
