RE: [nv-l] identical Netview environnement when modification

["Evans, Bill" <Bill.Evans@hq.doe.gov>]

This worked to keep two machines in sync at one account I worked.  It was run every night from a cron job on the primary host and the trap sent to the backup host caused it to run there. It could as well be run manually or by cron on the backup machine.  It may require some tuning and definitely requires trap definition on the backup machine. 

Happy reverse engineering.

Subject: [nv-l] identical Netview environnement when modification

Hello List, netview 7.1.3 fp 1 (aix 5.2)

 I've had a request from my telecom department about finding a way
(automatic) to have a identical Netview environnement for our 3 netview
server (lab, production and pre-production) when they do some netview
modification.

I mean, a script who copy all conf directories to another netview server or
something like that...
There exist a script ever made for that ? 
what files can i copy whitout any problem  (seed file, smarset file, mib
file (bin), trapd, ruleset ). 

Thanks
