Hi Alex, list,

as Sean wrote, it's not possible to access the SSdb more than once at a time, 
even if being placed on some sort of shared filesystem.
Each SpectroSERVER requires an exclusive database lock at startup.
What you could do is running a hot standby Spectrum installation, where both, 
primary and secondary SpectroSERVER will poll. However, this will just double 
network traffic and may reduce the time for the secondary to become active in a 
failover situation.
If you're running two separate servers, most of the things will be sparate 
(double), too: modeling, alarming, asset repoting, ...

Mit freundlichen Gruessen - Yours sincerely

Betreff: Re: [spectrum] [Spectrum] High availabilty model


In 8.1H15 which I am on you can model the same device on two separate 
landscapes, not sure what srm will do with it though but I believe it will show 
up separately in the srm database since the landsacpe/mh will be different but 
the names are what show up on most reports and not the devices so you may see 
duplicates depending on the report.  Also if you are using the built in trap 
forwarder it may have issues with the duplicates. As far as having a single 
database, if you are talking about the spectroserver sleepycat database I don't 
believe it is possible to have them share a single database either in 8.1 or 
9.1.  Both spectroservers should have backups to provide higher availability 
monitoring.  You could also use correlations to do this but I don't believe 
they are cross-landscape but I haven't played too much with correlations.


Regards,


Sean

Hi,

We are trying to have a high availability model with 2 Spectrum servers that 
connect to a single database that is available on a separate 3rd server.
We need to be able to monitor our assets from 2 different Spectrum servers live 
at the same time.
Is this feasible? If yes, is it tied to Spectrum 9.1?

Thanks in advance for your replies.

Best regards,

Alex Koueik
