hi,

i want to install 2 servers that one will act as a full server and the other just for connecting and viewing alarms.
how do i do that ?
do i have to have 2 databases ?
does both servers have to collect data in order to for me to see status and dci values ?
how do i sync the nodes and containers between the servers ?
do i have to define the same user on both servers rather then having just one ?

10x,
lindeamon

Yes, you have to have two separate databases.

Yes, if you need to see DCI values on both servers. However, if you only need to see alarms on second server, you can use event forwarding mechanism to forward events from primary server to secondary.

Unfortunately there are no object synchronization mechanism yet.

Yes, you have to maintain two user databases. You can simplify password management by using external RADIUS server for password checking, but you still need to create user accounts twice.
